Assessment Environment

It’s the trend to extend the operating license time, called Operating License Extension (OLE) in China, of nuclear power plants (NPPs) in the future. It needs to be adequately demonstrated by licensees and approved by the regulator to gain an extended license time, such as 20 years. The demonstration methods for OLE are different among countries due to the different management systems for NPPs. Safety assessment, environment effect evaluation and update of the final safety analysis report (FSAR) will be the main aspects during OLE demonstration of NPPs in China according to the technical policy issued by National Nuclear Safety Administration (NNSA). Technical methods for scoping and screening, aging management review and time-limited aging analyses, which are the main contents of safety assessment are established based on the technical policy drafted by NNSA and international experiences in order to assist the operators to implement the safety assessment for OLE of NPP.

Regulations governing the safety of drilling and offshore production operations have changed since the Macondo spill. This paper suggests management level perspectives on the nexus of human factors and safety management systems including an overview of ideas from: Congressional Testimony; the Bipartisan Policy Center inputs to the Presidents Commission on the Spill; the National Academy of Engineering and National Research Council Deepwater Horizon Report, and workshops and initiatives by RPSEA (Research Partnership to Secure Energy for America), SPE, and ASME. The value of benchmarks from risk management practices from the aviation, nuclear power, and financial community are also discussed. The paper will also consider questions as to what management might consider reducing risk and treating risk management as not just a cost center, but as a way to integrate safety management systems into improving corporate performance for all stakeholders.

The paper presents comparison of regular TVSA with average enrichment of 4,386% and hypothetical TVSA with enrichment of 10% based on design parameters and materials of TVSA fuel assemblies produced by TVEL (Russia), which today are widely used at nuclear power plants in Ukraine. It is shown that implementation of new fuel assemblies will result in improved use of fuel and increase of installed capability factor. At the same time, fresh and spent fuel management systems shall be modernized to meet relevant nuclear safety criteria. The paper analyzes possible criticality initiation at different stages of severe accidents related to core melt and using fuel with higher enrichment.

New Perspective

Safety culture (SC) is a modern paradigm of safety management of ultra-complex technical systems, primarily NPPs. According to the latest researches, the probability of an error made by a human, who professes the principles of safety culture, and the occurrence of accidents in general, compared to previ-ous methods of safety management, is reduced by hundreds of times. Therefore, it is necessary to pro-vide support as much as possible at all levels of government, to train all specialists and explore new pos-sibilities of this paradigm. This article is aimed at developing offers for an algorithm for automated as-sessment of the level of SC power units based on current indicators and indicators of structural units with a selected discreteness in order to further develop an appropriate cloud-based software which will eliminate subjectivism and record the smallest deviations, which, in its turn, will allow to take appropri-ate measures to improve the safety of nuclear power plants in the early stages of negative processes. The term «safety culture» was first formulated by the IAEA in 1986 in the course of the analysis of the causes of the Chernobyl disaster, and published in INSAG-1. The report stated that the lack of safety culture was one of the main causes of the disaster. Safety culture is defined as a set of values and ac-tions that occur as a result of an agreement reached in the team between the top managers and employ-ees to give security the highest priority in order to protect people and the environment. Further under-standing of this concept has led to a new perspective on the causes of other accidents and incidents at nuclear power plants that occurred in the past. The experience of NPP operation shows that their occur-rence is somehow related to people's behavior (namely, their attitude to safety issues), i.e., the current state of the level of safety culture. But as a current safety parameter (SC) it is estimated with a long pe-riod of time. The article offers automation of the assessment process.
