OKB “Gidropress” was established in 1946 to design nuclear installations of different type. At present, 50 WWERs of 35 GWe capacity are under operation in 8 countries (23 WWER-1000 and 27 WWER-440).More than 1000 reactor-years have demonstrated high level of WWER-type reactor safety and acceptable economical indices.National program of nuclear power expansion for near future is mainly oriented to advanced WWER-type reactors.Construction of a few advanced WWER-1000s are already licensed in different countries.
Average load factor for 14 Russian WWERs was 77,8% in 2002. In 2003, load factor for NVNPP (3 units) was 78%, for Kalinin (2 units) was 86.6%.
Nuclear electricity cost is 13% less than conventional.
First stage is lifetime extension and commissioning of units postponed in 80 / 90-ies.
NV-3, NV-4, Ko-1: additional licenses for 5 yrs
Second stage is based on new generation NPP designs, first of all - on advanced WWER-type reactors with passive safety features.
Implementation of passive safety features originally developed for AES 92 design (WWER-1000/V-392) is already started at Kudankulam, Tianwan, Balakovo projects.
WWER-1500/V-448 design is underway to be the basis for large-scale nuclear power extension.
Normative/legal docs of President and Government
Federal norms and rules

Normative docs of State management bodies
Clause 23: State regulation of safety…is… issuing of permissions (licenses) on the right to perform the works in area of atomic energy use, supervision on safety….
Clause 24: State regulation of safety… is being performed by special authorized Federal bodies of executive power for regulation of nuclear, radiation, technical and fire safety.
Clause 26: Permissions (licenses)… are being issued by State regulatory bodies to utilities and also to organizations performing works and providing services in area of atomic energy use.
Clause 35: Utility is fully responsible for safety of nuclear installation...
Federal supervision of Russia on nuclear and radiation safety (Gosatomnadzor RF) is Federal body of executive power.
It organizes and performs the state regulation of safety for atomic energy use (except of activities related to nuclear weapons and military nuclear power installations).
In accordance with the Law on Use of Atomic Energy (Clause 23), Gosatomnadzor RF is assigned to perform the above activities by Decree of President RF (No. 26 of January 21, 1997).
Supervision on nuclear and radiation
safety of NPPs
confirmation from relevant State management body on atomic energy use that applicant is capable to perform siting, design, construction, operation and decommissioning of NI;
Main document to be presented by applicant for NPP siting, construction, commissioning, operation and decommissioning: Safety Substantiation Report (SSR)
As for reactor plant, Chapter 15 is to verify the meeting of so called acceptance criteria:
Basic mean to verify the fulfillment of above acceptance criteria is accident analyses for full list of initiating events and scenarios using TH and other codes.
Main safety standard OPB-88/97 indicates that sample lists of initiating events for DBAs and BDBAs shall be given in normative documents.
Up to now, no “normative” list for BDBAs is available.
Sample minimal list for DBAs (internal and external events) is given in PNAE G-01-036-95 (format and content of SSR).
