Mumbai, India

The Nuclear Power Corporation of India Limited is a government-owned corporation of India based in Mumbai.It is wholly owned by the Central Government and is responsible for the generation of nuclear power for electricity. NPCIL is administered by the Department of Atomic Energy, Govt. of India . NPCIL was created in September 1987 as under the Govt. Act 1956, "with the objective of undertaking the design, construction, operation and maintenance of the atomic power stations for generation of electricity in pursuance of the schemes and programmes of the Government of India under the provision of the Atomic Energy Act 1962." All nuclear power plants operated by the company are certified for ISO-14001 . NPCIL was the sole body responsible for constructing and operating India's commercial nuclear power plants till setting up of BHAVINI. As of 10 August 2012 the company had 21 nuclear reactors in operation at seven locations, a total installed capacity of 5780 MWe. Subsequent to the government's decision to allow private companies to provide nuclear power, the company has experienced problems with private enterprises "poaching" its employees. Wikipedia.

The nodal methods are significantly more accurate than the traditional methods such as finite difference method (FDM), finite element method (FEM) etc. However, these methods can be used only for the nodes of only a few limited shapes such as rectangular (in 2D) or cuboidal (in 3D). In this paper the approach for solving neutron diffusion equation in 2-d cylindrical polar geometry (r,θ) using nodal method is discussed. The analytic nodal method using transverse integration process is used to solve the 2-d neutron diffusion equation in polar coordinate. The problem involved with the transverse integration in θ-direction has been resolved by approximating the average of products by product of averages. This approximation leads to three different formulations of the scheme. A detailed study of the numerical error for source problems having analytical solutions is carried out. Using this analysis it has been shown that the error is second order for these problems irrespective of the formulation used. In addition to that the methodology is used to solve criticality problems for which analytical or benchmark solutions are available. The solution of the source problem shows that method maintains its accuracy and order even with approximations made to deal with transverse integration in θ-direction. The comparison of eigenvalues obtained with current methodology with those obtained analytically or available as benchmark show that the method is capable of accurately predicting the eigenvalues. © 2017 Elsevier Ltd

NucNet: Private companies have invested over $1bn in the development of small modular reactors (SMRs), but more investment through public-private partnerships is needed to assure that SMRs are a viable option in the mid-2020s, the US-based SMR Start industry consortium said in a policy statement. SMR Start is urging Congress to authorize sufficient funds for an SMR commercial deployment program and called for the continuation and expansion of the existing licensing technical support program to include the design and engineering, regulatory review and approval of SMR technologies and facilities. The statement said that in addition to accomplishing the public benefit from SMR deployment, the federal government would receive a return on investment through taxes associated with investment, job creation and economic output over the lifetime of the SMR facilities that would otherwise not exist without federal investment. It also called for continuation of the loan guarantee program to support financing for the design and construction of SMR facilities and SMR component manufacturing facilities. The policy statement is online: http://bit.ly/2kQM1vG Members of the consortium include AREVA, Bechtel, BWXT, Dominion, Duke Energy, Energy Northwest, Fluor, Holtec International, NuScale Power, Ontario Power Generation, PSEG Nuclear, Southern Nuclear, TVA, and UAMPS Plant Vogtle could use new fuel when MOX is complete Augusta Chronicle: Proponents of the Savannah River Site’s mixed-oxide (MOX) fuel fabrication facility are touting the possibility that once in production, its output, PWR type fuel assemblies in the form of MOX fuel, could be used at Units 3 and 4 at Southern Nuclear’s Plant Vogtle. According to Areva Nuclear Materials LLC, one of the companies involved in MOX design and construction, the Energy Department planned for a subsidized cost structure to make the MOX fuel more attractive. Plant Vogtle, which could have four operating reactor units when the MOX plant is finished, could make the switch to the mixed-oxide fuel. Up to one-third of the reactor’s fuel assemblies could be MOX fuel. The advantage of the fuel is that there are longer periods between fuel outages during which time the reactor is not generating electricity nor making any money for its investors. “In order to accommodate the potential use of MOX fuel, modifications would be required for the plant’s physical structure, as well as the processes and procedures used to operate the facility.” He might have also added that the plant would have to modify the NRC license for each reactor based on the change in fuel type. The agency has no experience with this kind of modification of a license. AP: A federal appeals court has rejected a Virginia company’s bid to end the state’s decades-long ban on uranium mining. A panel of the 4th U.S. Circuit Court of Appeals in Richmond has upheld the ruling of a district judge who threw out a lawsuit from Virginia Uranium Inc. challenging the ban. The Pittsylvania County company wants to mine a 119-million-pound deposit of the radioactive ore. It argued that a federal law should pre-empt state regulations, but the courts disagreed. Does India still want the Westinghouse reactors despite Toshiba meltdown? Reuters, PTI: In a burst of what can charitably be characterized as wishful thinking, an Indian government official said he does not expect fallout from the financial meltdown at Toshiba Corp to halt plans to buy six nuclear reactors from the Japanese company’s U.S. nuclear unit Westinghouse. Indian wire services added details to the report. This statement was not made by NPCIL which is the main actor in all matters related to building new nuclear power plants. This raises a question of how credible the statement is as an expression of the Indian’s government’s views on Toshiba’s financial troubles. India has been in talks for years to build six Westinghouse AP1000 reactors in the southern state of Andhra Pradesh under its drive to expand nuclear generation and to move the economy off polluting fuels like coal. “As for the technical execution of the project, I do not see many problems,” Sekhar Basu, secretary of the Department of Atomic Energy that reports directly to Modi, told Reuters in a short telephone interview. The wire service reported that negotiations on the technical and commercial terms of the reactor deal have reached an advanced stage. Not mentioned in the report is any measure of relief from the terms of the supplier liability law that has kept U.S. firms out of the Indian market. Industry experts said that, if the project is still at all viable, the main logistical challenge would be to locate civil engineering contractors since Westinghouse would only provide the reactors. India has not yet signed a contract with Westinghouse, nor has cash changed hands. Basu said that talks on financing had not yet begun in earnest. Significantly, he also said the state-owned Nuclear Power Corporation of India (NPCIL) had yet to be updated by Westinghouse on recent developments. Westinghouse and NPCIL did not respond to requests for comment from wire service reporters. Separately, there is considerable pressure within India’s nuclear industdry to abandon the Westinghouse reactor project and build 700 MW PHWR reactors based on an Indian adaptation of the CANDU technology. Further, an amendment to the enabling legislation for NPCIL allows it to do joint development efforts with heavy industry such as steel and petrochemicals and even provide electricity for India’s vast electrified rail network. This is seen as an advantage and would build domestic capabilities, supply chains, and not have India relying on western technology. Albuquerque Journal: WIPP said it expects to begin accepting shipments of nuclear waste from storage sites around the country in April. Feb 14th marked three years since a radiation accident contaminated the Waste Isolation Pilot Plant outside Carlsbad. After struggling to clean up the deep underground repository, WIPP commenced waste emplacement last month. WIPP has been moving waste drums underground from an above-ground warehouse, where waste was being temporarily held when a drum of radioactive material burst underground on Feb. 14, 2014, and WIPP was shut down. WIPP has started off slowly, making just two emplacements per week from the waste handling building, according to a spokesman. When shipments begin, the facility is aiming to make about four emplacements per week by the end of the year compared with an average of 17 per week before the accident. Los Alamos National Laboratory is on the list of those sites expected to begin shipping in April, along with Department of Energy facilities at Idaho, Oak Ridge and Savannah River. LANL faced its own issues after investigators discovered that the drum that burst at WIPP had been improperly packed by a LANL subcontractor. The Idaho Falls Post Register reported that the Idaho Cleanup Project will send an estimated 61 shipments of radioactive waste to New Mexico’s Waste Isolation Pilot Plant over the next year, more than any other site, U.S. Department of Energy officials said. While Idaho cleanup contractor Fluor Idaho will send more than twice the number of shipments of any other site, it will not be nearly enough to make the necessary progress toward meeting a Dec. 31, 1995, Settlement Agreement deadline with the state of Idaho. Idaho has more than 900 shipments — or more than 20,000 individual containers — of transuranic waste that are supposed to leave by the end of next year.

National Security Group commandos prepare to launch an assault during a drill to tackle a mock terror attack ahead of Republic Day in New Delhi, India, Thursday, Jan. 21, 2016. India is tightening security with extra paramilitary soldiers and police deployed across the capital after a French consulate in southern India received a letter warning against the visit of French President Francois Hollande. (AP Photo/Altaf Qadri) More NEW DELHI (AP) — Amid the pomp of a military parade, the leaders of France and India are planning ambitious discussions next week in New Delhi that could end with a multibillion-dollar deal for combat airplanes and closer cooperation on counterterrorism and clean energy. French President Francois Hollande arrives Sunday to tour the northern city of Chandigarh before traveling to the Indian capital for meetings with officials and a place as guest of honor on Tuesday at India's Republic Day parade, celebrating 66 years since the country adopted its constitution. High on the agenda will be India's desire to purchase 36 Rafale combat planes for its air force, which Modi had announced during a visit to Paris in April, touching off several rounds of negotiations over pricing, offsets and servicing. Indian Defense Minister Manohar Parrikar said last week that the deal was "close to completion," and another Indian official said this week that the two sides hoped to sign a deal during Hollande's visit. That official spoke on condition of anonymity because he was not authorized to speak with media. India and France have shared close ties for decades, holding high-level meetings every year since signing a strategic partnership agreement in 1998. They share concerns over terrorism, climate change, space exploration and military cooperation. India first began talking to France four years ago about buying 126 Rafales — a deal that would have cost roughly $12 billion, with a majority of the planes to be made in India. New Delhi has since pared that order down to 36 "ready to fly" planes, to be built in France. France has also promised support for India's clean-energy quest, including a solar energy alliance launched last month during the global climate talks held in Paris. Hollande and his French officials are also likely to press India about ongoing delays in building a six-reactor nuclear power plant complex in the town of Jaitapur in the west Indian state of Maharashtra. French nuclear giant Areva SA and the Nuclear Power Corporation of India agreed in 2010 to build the 9,900-megawatt facility, but progress has been slow amid disputes over land rights and Indian laws on accident liability. Paris has said it could help India upgrade its crumbling railway infrastructure, especially with its expertise in high-speed trains. Japan also said recently that it would fund a "bullet train" connecting the Indian financial capital of Mumbai with the western city of Ahmadabad. Indian officials said France and India were working hard on an agreement for another high-speed link in northern India, but would not immediately say which cities might be along the route. Hollande begins his trip Sunday by visiting Chandigarh, which stands as the capital of both Punjab and Haryana states. Designed in the 1950s by Swiss-French architect Le Corbusier, Chandigarh is one of three cities that France has pledged to help develop as so-called "smart cities" — with clean water supplies, efficient sewage disposal and public transportation, among other programs. The other two cities adopted by France are the central city of Nagpur and the former French colony of Pondicherry in the south. Hollande will be accompanied by a high-profile delegation including the ministers of defense, foreign affairs, economy and culture and dozens of top corporate leaders. In Chandigarh, Hollande and French business leaders will meet with Indian counterparts eager to boost bilateral trade, which in 2014 stood at $8.6 billion. New Delhi is also trying to encourage French companies to tap into India's economic boom. On Monday, Hollande will hold talks in New Delhi with Modi and other Indian officials. The two leaders are expected to touch on anti-terrorism efforts including speeding up extradition requests and cracking down on money laundering used to fund militant activities. Vikas Swarup, spokesman for India's foreign ministry, noted that both countries had been hit by militants recently, with 130 people killed across Paris on Nov. 13 and a four-day siege against the north Indian air force base of Pathankot that left seven Indian soldiers dead earlier this month. "Following the horrendous attack in Paris and the recent terrorist attack at the Pathankot air base, it would be worth highlighting that cooperation between France and India on matters related to counterterrorism has acquired a very significant dimension," Swarup said at a media briefing Thursday. "Both India and France are victims of terrorism and we can expect a lot of discussions on this particular issue." Hollande caps his visit on Tuesday by attending a two-hour parade displaying India's military hardware and marching bands. He would be the fifth French president invited as the guest of honor at the ceremony. Last year, U.S. President Barack Obama joined Modi at the parade.

Knee and hip joint replacement implants involve a sliding contact between the femoral component and the tibial or acetabular component immersed in body fluids, thus making the metallic parts susceptible to tribocorrosion. Micro-motions occur at points of fixation leading to debris and ion release by fretting corrosion. β-Titanium alloys are potential biomaterials for joint prostheses due to their biocompatibility and compatibility with the mechanical properties of bone. The biotribocorrosion behavior of Ti-29Nb-13Ta-4.6Zr was studied in Hank's balanced salt solution at open circuit potential and at an applied potential in the passive region. Reciprocating sliding tribocorrosion tests were carried out against technical grade ultra high molecular weight polyethylene, while fretting corrosion tests were carried out against alumina. The wear of the alloy is insignificant when sliding against polyethylene. However, depassivation does take place, but the tested alloy showed an ability to recover its passive state during sliding. The abrasivity of the alloy depends on the electrochemical conditions of the contact, while the wear of polyethylene proceeds through third body formation and material transfer. Under fretting corrosion conditions recovery of the passive state was also achieved. In a fretting contact wear of the alloy proceeds through plastic deformation of the bulk material and wear resistance depends on the electrochemical conditions. © 2011 Acta Materialia Inc.

In a practical situation, it is difficult to model exact contact conditions due to challenges involved in the estimation of contact forces, and relative displacements between the contacting bodies. Sliding and seizure conditions were simulated on first-of-a-kind displacement controlled system. Self-mated stainless steels have been investigated in detail. Categorization of contact conditions prevailing at the contact interface has been carried out based on the variation of coefficient of friction with number of cycles, and three-dimensional fretting loops. Surface and subsurface micro-cracks have been observed, and their characteristic shows strong dependence on loading conditions. Existence of shear bands in the subsurface region has been observed for high strain and low strain rate loading conditions. Studies also include the influence of initial surface roughness on the damage under two extreme contact conditions. © 2013 Elsevier B.V.

In nuclear power plants, continuous efforts are made to ensure that plants are operated in safe, reliable and economical manner. While utmost care is taken during design, construction and commissioning of the structures, systems & components (SSCs), continued healthiness has to be ensured during operation phase in accordance with the design intent. This is primarily achieved through the establishment of a comprehensive life management programme of surveillance, condition monitoring, periodic Inservice inspections (ISI) and maintenance, the purpose of which is to ensure that required safety margins are maintained for all important SSCs throughout plant service life. In any industry, the important mechanisms which lead to SSCs degradation are general corrosion, Flow accelerated corrosion, erosion, thermal effects, fatigue and mechanical wear & fretting. In a Nuclear Power Plant, in addition to these, degradation also occurs due to irradiation and creep. Therefore SSCs need to be designed with due consideration of all such degradation mechanisms. During operation phase, the limiting conditions for operation and requirements of surveillance & condition monitoring for all components important to safety are documented in Technical Specification. A plant specific ISI manual defines and elaborates the ISI internal inspection methods and acceptance criteria. The ISI requirements are decided taking into account best industry practices and operational experience and meet the requirements of existing codes and standards. Both these documents are approved by AERB. In pressurized heavy water reactors, major components covered in ISI programme are coolant channels, feeder pipes, steam generators, heavy water heat exchangers, pressure boundary components, relief valves etc. The inspection methods adopted include use of UT, ECT, DPT and visual inspection. In addition to functional checks for some of the components, ferrography, vibration monitoring and thermography etc are also utilized for rotating equipment. The SSCs where unacceptable indications are revealed by ISI are repaired, replaced or isolated. The base line data generated during Pre-Service inspection is used for comparing and trending of observations. The observations made during ISI are subjected to thorough review and analysis by qualified experts to obtain assurance that unacceptable degradation in component quality is not occurring and it remains fit for service. The containment system of a NPP plays a crucial role in minimizing dose to the public in case of an accident situation. The integrity of Primary and Secondary Containment is assessed by conducting integrated leak rate tests in every Biannual Shut Down. The concrete structure is also subjected to NDT checks on a specified frequency to ensure continued healthiness. Indian nuclear power plants have accumulated an operating experience of more than 380 reactor years of operation. Over the years, the programmes for surveillance, condition monitoring and in-service inspections have been improved significantly and match with best in the industry. As a result, there has been no major age related failure in any of the important SSCs and thus continued safe and reliable operation of NPPs is assured. This paper brings out the ISI & health monitoring methodology adopted at Indian NPPs, to ensure safe and reliable operation. © 2014 Published by Elsevier Ltd.

This paper reports the state of the art of using a solid-state Nd:YAG laser for material processing applications such as cutting, welding and drilling of several components of operational nuclear reactors in radioactive environment. We have demonstrated several advantages of laserbased material processing over conventional methods, and these are discussed briefly. At NPCIL, we have used laser techniques to cut stainless steel sheets up to 14 mm thickness and stainless steel weld up to a depth of 3 mm. This remotely operable laser system has been engineered for its robustness with proper fixtures and tooling for various material processing operations on industrial scale. © Indian Academy of Sciences.

The Asian region, most populous and fastest growing in terms of economic growth, has countries with lowest per capita energy/electricity consumption. Barring the Middle East, the rest of the region is, by and large, modest in conventional energy resources. This is also a region where large sections of population suffer from income inequality and inadequate economic development. Economic growth and quality of life of a population depend heavily on per capita availability of energy/electricity, and thus there is an urgent need to increase the per capita electricity production/consumption in the region. Unlike in the past, it is the Asian region that is poised to dwarf the today's developed world in new capacity addition in the coming years. This fact alone asks for sensible choices to be made. Also, the Asian region is quite vulnerable to the effects of climate change, given the geography and population distribution. Today, governments must seriously consider the environmental impact of electricity generation, in order to help mitigate global warming and its consequences. Nuclear power, being environmentally benign, affords sustainability at the very outset. But that's not all. The other compelling reasons in favour of nuclear power are its compact nature as a source of energy and the promise of long-term energy security. Nuclear power is, therefore, inevitable for the region. Recognising this, the rapidly developing countries in the region - such as India and China - are pursuing ambitious nuclear power programmes, while several other countries in the region are also planning to embark on the nuclear power route for electricity generation. As nuclear power is inherently technology-intensive, there is a need for greater cooperation, to reach out to countries that presently do not have the technology base for starting nuclear power programmes on their own. Even in the countries with established commercial nuclear power programmes, there is a need to reach out to the people to demonstrate the merits, safety aspects and economic competitiveness of nuclear power, and also the role of nuclear power in the preservation of the environment. The imperatives of the current scenario warrant building confidence among the people regarding nuclear power through sharing of credible information on all its aspects to remove misconceptions. This paper describes the current scenario, key issues, challenges and possible ways to address them. The paper also briefly describes the Indian nuclear power programme for being the second-most aggressive player in the nuclear arena in this region, after China. © 2011 Published by Elsevier Ltd.
