Ways of Involving New Project Partners

  21. Analysis of the Russian practice in development PCS is based on sufficiently developed base of standards, norms and regulations and demonstrates the following: Referring to standards, norms and regulationsdefining the requirements to HW, there exist a high degree of Russian and international standards’ requirements correspondence. At the same time one should consider that over 300 Russian standards relating to HW and about 15 relating toSWare fully identical to IEC and ISO standards; Referring to standards, norms and regulations defining the requirements to SW,the Russian normative base is insufficiently developed and does not satisfy the present-day requirements. Arrangement of NPP PCS Normative Base (1/4)

  22. Arrangement of NPP PCS Normative Base (2/4) JSC “VNIIAES” elaborated proposals on application of international IAEA and IEC standards to SW in PCS designs of NPP Units under construction and design. Proposals for introducing a package of standard documents, international ones including, were discussed with Rostechnadzor. These proposals are timely and urgent in the context of changes in Federal Law № 184-FZ, dated of 27 December 2002, “On Technical Regulation” accepted at the initiative of the Russian Federation President, determining a possibility of acknowledging and using the international and foreign standards and codes in the Russian Federation.

  23. JSC “VNIIAES” in cooperation with Institut fur Sicherheitstechnologie GmbH, Germany and Institutt for Energiteknikk, Norwayelaborated the first drafts of the following normative documents: ”Nuclear Plants. Control Systems. Assessment of Software Tools Quality and Reliability”; ”Nuclear Plants. Control Systems. Classification and Qualification”; ”Nuclear Plants. Control Systems. General Requirements”. The above normative documents on development of computer-based PCS may become the basis for elaboration of federal safety norms and rulesin the area of nuclear energy use. The elaboration is carried out by joint efforts of the State Corporation “Rosatom” organizations and Rostechnadzor. Arrangement of NPP PCS Normative Base (3/4)

  24. JSC “VNIIAES” elaborated a package of guidelines, defining requirements to new generation of PCS on the basis of SW and programmable facilities, requirements to testing, verification, validation, qualification and certification, five of which are submitted for approval to JSC “Atomenergoproject”, JSC“SPbAEP”, RSC“Kurchatov Institute”, JSC OKB“Gidropress” In February 2010 the first draft of the guideline “Nuclear Plants. Control Systems. Stages and Phases of Development. General Provisions” was elaborated and distributed for review, where the requirements are set out to all stages and phases of PCS development and introduction, to the composition and contents of the documents at all stages and phases.

  25. The Russian enterprises have sufficiently great scientific and industrial potential for creation of competitive Russian PCS, which allows us today together with foreign companies to ensure the world scientific and technical level of NPP PCS, and in the near future to compete with the West on equal terms in the area if information technologies. JSC “VNIIAES” in cooperation with the industry enterprises elaborated, introduced and currently are improving and introducing state-of-the-art control systems of in-house design, well comparable with foreign analogues;the PCS test site is functioning. In the industry a complex of activities is being implemented on improving the works on development and introduction of a competitive Russian PCS, specifically, in frames of standard design of optimized and informatized VVER Unit (VVER-TOI). Conclusions (1/2)

  26. Technical and commercial proposals were prepared to participate in tenders on supply and putting into operation of PCS for NPP of Russian design (NPP in Turkey, India, Czechia, Hungary). Currently a new enterprise JSC “VNIIASU” is in the process of creation in the interests of the industry to perform the development and complete supply of “turnkey” PCS for the NPPs being finished and the NPPs of new generation. An up-to-date normative base is under arrangement for NPP PCS development and introduction based on computing machinery and harmonized with the international standards Conclusions (2/2)
