The isolation and anti-misopertaion control system utilises HMI (Human Machine Interface) software, smart keys and NFC (Near Field Communication) locks to provide electronic management and verification of Isolations and switching procedures. The smart keys can be used for all the functions of an Android mobile phone but also includes an NFC reader-writer to work with specialist hardware and our own NFC locks. The NFC lock is a specially formulated padlock with NFC chip that can store data and be controlled via a smart key. The Smart Isolation and Anti-Misoperation System consist of the following major components: HMI (Human Machine Interface) software - Utilising the HMI software, operations engineers can rehearse the isolation or operation process via interactive electronic Process & Instrument Diagrams (P&ID's). The operational sequence and logic is then automatically checked by the system and alarms and highlights used where required. Once the correct sequence and process is identified the details can be downloaded to the smart key ready to be implemented on the plant. Another very useful validation can be gained from analysing the equipment status from DCS via 4G, WIFI or Bluetooth. This data can look at voltage, flow rates or pressure in a particular part of the system to see if the Isolation or switching process was successful. In such cases the system can also send a blocking signal back to the DCS or Operations engineer to prevent arbitrarily starting or shutting down the equipment. NFC (Near Field Communication) locks - Have 2 modes of operation, utilising keys or utilising the smart lock technology. The NFC locks with keys work in the same way a conventional padlocks but with the ability to store data on their internal RFID chip of the lock. Normally only the Isolation tag is available for data but with NFC Locks much more information can be stored and read with any Android device. When operations engineers use the NFC locks the data relating to the Isolation or OT is stored on the NFC Lock. Any Android mobile device with an NFC reader can then be used to read the data by contacting the devices. Thus, the interaction between manual operation and DCS operation is bridged by "Internet of Things (IOT)" technology. Smart key - On critical plant and equipment, permanent NFC locks can be used to ensure that points of isolation are kept in the operational position. When switching process via an Operations Ticket (OT) these locks must be removed with the smart key which also acts as a verification that this is the correct point. This is achieved via the NFC chip data holding the Equipment ID for the selected equipment, if this ID does not match the equipment ID in the approved, downloaded sequence it will not open the lock, thus preventing mis-operation. The Smart key is not designed to replace full Isolation management which should still use a lock, key and LOTO box setup as described. In these cases, the smart key would only be used to remove permanent locks on critical equipment before changing the state of the isolation point and applying a lock with a key (Weather that is an NFC lock or conventional padlock).

This article presents a structural equation model for exploring the impact of environmental regulations - administrative-based environmental regulation (command-and-control regulation) (AER) and market-based environmental regulation (MER), on Chinese firm behavior and competitiveness on the basis of data collected from Chinese electric power and iron and steel firms (most of these firms are state-owned enterprises). Our results show that both AER and MER promote the firm behavior shift toward green development, and enhance firm competitiveness. However, AER and MER have different impacts on firm specific behaviors such as strategy choice, production decisions, technical progress, and environmental management and different extent of impact on firm competitiveness. In addition, whilst AER has a strong significant positive impact on technological innovation and plays a direct role in competitive improvement, MER does not. On the other hand, only MER plays significant roles in promoting the behavior shift of strategy toward green development. These findings signify that it is important for China to pursue the coordination between AER and MER, and to identify the line of playing roles between AER and MER. © 2014 Published by Elsevier Ltd.

The power industry is the largest air polluter in China, contributing nearly 40% of CO2 emissions and 60% of SO2 emissions. Under mounting pressure to improve standards of environmental protection, it is imperative that the industry increases the efficiency and environmental performance of power plants in China. We investigate the impacts of three different environmental regulations on efficiency improvement and CO2 reduction: command and control regulations (CCR), market-based regulations (MBR), and government subsidies (GS). We find that MBR and GS have a positive impact on efficiency improvement and CO2 reduction. However, CCR have no significant impacts. This finding has important implications since CCR dominates China's environmental policy. We discuss the policy implications of these findings, such as China should further release the potential of MBR in the power industry, instead of solely relying on CCR; and pay more attention to the coordination of different policy instruments. © 2015 Elsevier Ltd.

In an electron beam irradiation flue gas desulfurization and denitrification technical model, the track and the equivalent dose field of electron beams with different inject energy were simulated with Geant4 toolkit. Simulation results show that electron beam with 1.75 MeV matches with 1 000 MWe level power plant flue gas desulfurization and denitrification technical design. The simulation results will be beneficial to the engineering design and the accelerator parameter optimization.

To study the neutron leakage spectrum of spallation target of ADS, the neutron leakage spectrum of lead-bismuth eutectic target with 1 GeV proton was simulated by Geant4 toolkit. The simulated neutron leakage spectrum and target optimization parameters, which will be beneficial to the reactor core design, are obtained.
