Site Evaluation

Abstract Site survey in the potential site of the Nuclear Power Plant (NPP) construction is an essential preliminary activity. Site survey has a crucial role in successful NPP construction. Several factors are contributing to a successful site evaluation. One of them is the Site Evaluation Management System (SEMS). Indonesia National Nuclear Regulatory Body (BAPETEN) had stipulated Head of BAPETEN Decree No. 4 the Year 2010, about Management System for Activities and Facilities. A site survey activity needs to adhere to the requirements in the regulation above, consisting of the management system, management’s responsibility, resources management, implementation process, monitoring, measurement, evaluation, and correction. The implementation of SEMS is conducted with the methods of a plan, do, check, and action and applied to these site survey phases: survey planning, survey implementation, survey audit, and survey review. It found that the SEMS implementation with the preliminary risk assessment significantly improves the safety of the site survey activity. The risk assessment result is categorized as follows: acceptable risk, tolerable risk, intolerable risk, and unacceptable risk. The risk assessment was conducted by following site survey activities: seismic, volcanic, meteorologic, hydrologic, geotechnical and foundation, human-induced events, and population distribution and density. It found that the implementation of SEMS with preliminary risk assessments supports the Indonesia energy security, which includes 4A: Availability (the availability of the energy kind), Accessibility (the accessibility to utilize the energy), Affordability, and Acceptability (public’s acceptance to the energy utilization). Site survey activities that meet the Availability criteria are from these aspects: seismic, volcanic, meteorologic, hydrologic, geotechnical, and foundation; while the site survey activities that meet the acceptability criteria are from these aspects: human-induced events, and population distribution and density. The implementation of SEMS has a better impact on the site survey activity when a series of risk assessments is conducted beforehand. It also found that the implementation of SEMS with preliminary risk assessments fulfills the 4A of Indonesia Energy Security: availability, accessibility, affordability, acceptability.

Abstract This paper addresses the use of a new nuclear power plant performance risk analysis tool. The new tool is called Versatile Economic Risk Tool (VERT). VERT couples Idaho National Laboratory’s SAPHIRE and RAVEN software packages. SAPHIRE is traditionally used for performing probabilistic risk assessment and RAVEN is a multi-purpose uncertainty quantification, regression analysis, probabilistic risk assessment, data analysis and model optimization software framework. Using fault tree models, degradation models, reliability data, and economic information, VERT can assess relative system performance risks as a function of time. Risk can be quantified in megawatt hours (MWh) which can be converted to dollars. To demonstrate the value of VERT, generic pressurized water reactor and boiling water reactor fault tree models were developed along with time dependent reliability data to investigate the plant systems, structures, and components that impacted performance from the year 1980 to 2020. The results confirm the overall notion that US nuclear power plant industry operational performance has been improving since 1980. More importantly, the results identify equipment that negatively or positively impact performance. Thus, using VERT, individual plant operators can target systems, structures, and components that merit greater attention from a performance perspective.

After several years of intense labor by many industry people, ASME is about to issue its newly approved PRA standard. This standard is for probabilistic risk assessment (PRA) for nuclear power plant applications. It is not a standard on how to build a PRA model; although, that could be inferred from the standard’s technical requirements. This Standard sets forth requirements for PRAs used to support risk-informed decisions related to design, licensing, procurement, construction, operation, and maintenance. It also prescribes a method for applying these requirements depending the degree to which risk information is needed and credited.

The data on the current state of energy in Uzbekistan are given. The need to diversify the structure of the energy balance of the republic is shown, which ensures the energy security of the state in the medium and long term. It is argued that the construction of a nuclear power plant in Uzbekistan is not only expedient, but also necessary. In the future, renewable energy and nuclear power plants will become the basis of energy in Uzbekistan.
