The State review on nuclear and radiation safety is a set of organizational, scientific and technical, expert and analytical activities that is carried out by the authorized body of state nuclear and radiation safety regulation – SNRIU with the purpose of independent assessment of technical safety level in the area of nuclear energy, taking into account all factors resulting in nuclear and radiation hazard for human health and the environment, including physical protection assurance.
SSTC NRS is the SNRIU main expert organization and upon SNRIU requests reviews the materials submitted by the Licensee, verifies the compliance of technical decisions with the requirements of the current Ukrainian legislative and legal acts, standards, rules and regulations on nuclear and radiation safety, analyzes the completeness and adequacy of initial data and assumptions, correctness of calculations performed, results and conclusions received in order to assess safety in nuclear energy use.
Methodological basis for expert reviews is based on quality management system regulations. The most important review methodologies were implemented by SNRCU as the branch regulations.
Information support is implemented through the existing databases operating within the unified information system. Calculation-analytical support of the expert activity includes about 40 software tools.
The SSTC NRS expert activity is up to 70% of the annual scientific and technical activity. Efficiency of the Center expert activity is ensured by direct interaction of SSTC NRS experts while performing technical assessments with experts of NAEK “Energoatom”, Ukrainian NPPs, design and scientific-research organizations participated in development of the documents submitted for review.
Scientific and technical support to the SNRIU inspection activity is focused on:
identification of methodological approaches to target inspections;
development of inspection procedures;
analytical research on mastering the advanced experience and its implementation;
conduction of joint inspections, analysis of the results obtained and development of corrective measures.
Special attention was paid to scientific and technical assistance in the inspection activity at Khmelnytsky NPP power unit No.2 and Rivne NPP power unit No.4 commissioning stage, and in SIP implementation.
A set of documents consisting of procedures for target inspection examinations was developed for regulatory support to the state supervision at the Shelter.
In 2007 SSTC NRS scientific and technical product, “Review of materials on nuclear and radiation safety substantiation”, within the All-Ukrainian competition on production quality (goods, activities, services) “100 the best goods of Ukraine” was awarded with two diplomas and a medal, and was presented in catalogue “100 the best goods of Ukraine” in 2006-2007.
