The nuclear fuel cycle is investigated for the perspective of the nuclear non-proliferation. The random number generation of the Monte-Carlo method is utilized for the analysis. Five cases are quantified by the random number generations. These values are summed by the described equations. The higher values are shown in 52nd and 73rd months. This way could be a useful obligation in the license of the plant construction. The security of the nuclear fuel cycle incorporated with nuclear power plants (NPPs) is investigated using social impact theory. The dynamic quantification of the theory shows the non-secured time for act of terrorism which is considered for the non-secured condition against the risk of theft in nuclear material. For a realistic consideration, the meta-theoretical framework for modeling is performed for situations where beliefs, attributes or behaviors of an individual are influenced by those of others. © Carl Hanser Verlag, München.

The power increase in the nuclear power plants has been investigated for the safety aspect. Most equipment could be affected by the power uprate, which could increase the electricity power level. The quantification of the uprate reliability is performed by the system dynamics method, which is processed by the feedback and accumulation algorithms. The Vensim software package is used for the simulations, which is made by the Monte Carlo method. There are two kinds of considerations as the economic and safety properties. The result shows the stability of the operations when the power can be decided. This shows the higher efficiency of the reactor. The maximum value of risk is 157,887 in 2065 and the minimum value is 2 in 2010. Thus, the risk of the power uprate increases 78,954 times higher than the initial value in this study. © 2015 Taylor and Francis Group, LLC. Source

The dynamical assessment has been performed in the aspect of the nuclear power plants (NPPs) security. The physical protection system (PPS) is constructed by the cyber security evaluation tool (CSET) for the nuclear security assessment. The systems thinking algorithm is used for the quantifications by the Vensim software package. There is a period of 60 years which is the life time of NPPs' operation. The maximum possibility happens as 3.59 in the 30th year. The minimum value is done as 1.26 in the 55th year. The difference is about 2.85 times. The results of the case with time delay have shown that the maximum possibility of terror or sabotage incident happens as 447.42 in the 58th year and the minimum value happens as 89.77 in the 51st year. The difference is about 4.98 times. Hence, if the sabotage happens, the worst case is that the intruder can attack the target of the nuclear material in about one and a half hours. The general NPPs are modeled in the study and controlled by the systematic procedures. © 2013 Tae Ho Woo. Source

The operation of nuclear power plants (NPPs) has been investigated in the aspect of safeguard assessment. The risk of the terrors in NPPs is one of the critical points in secure power operations. The basic event of the related incidents is quantified by game theory. The Cobb-Douglas function of the production function is modified and developed as the Safeguard Production Function. The standard productivity is compared with the interested power. Using the life extension, the range of the secure operation in 2,000 MWe is between 1.00 and 8.00 and the range in 600 MWe is between 0.00 and 1.00. This means the highest value in the range of secure power operation is about 8 times higher than that of the interested power operation in this study. The safeguard assessment is quantified by the life extension of the NPPs. Finally, the nuclear safeguard protocol is constructed for the successful safe operation. © Taylor & Francis Group, LLC.

Nano-robotics is introduced for the nuclear industry for radiation treatment as a complete cure of cancer because it leads to the removal of cancerous cells. In order to ensure the reliability of treatment, one needs to control the radiation behavior of the therapy. The omni-directional cancer treatment program (OCTP) is suggested for the therapy planning in which all cancerous cells are killed without damage to normal cells. This is one of the most important issues in the conventional radiation therapy planning. The clinical cancer therapy planning is performed by nanorobots. The tiny machine treats the cancer cells effectively. The collision event occurs approximately over 35 nm. Therefore, if the diameter of tumor is 1 cm, the curable length is about 5 nm. Thus, one movement of nanorobot radiates about 10 nm in two dimensional planning. The example organ in this study is the breast. Nanorobots enter from the upper side of breast and exit from the lower side of the breast in the clinical example. © 2015 Elsevier Ltd. All rights reserved. Source
