The project coordinator from Argonne National Laboratory (ANL) met with staff members of the Scientific and Engineering Center for Nuclear and Radiation Safety and representatives from Atomenergoproject (AEP) to discuss the progress of the peer review of the Novovoronezh NPP Unit 3 probabilistic risk assessment (PRA). Problems concerning the availability of documentation from AEP and the NPP were addressed and resolved. The task order to carry out a limited scope of external events in the extension of the PRA was discussed. The work scope was agreed upon and a detailed discussion of labor efforts for each technical subtask was discussed as well as requirements for translation and travel. Atomenergoproject agreed that the work would be completed by December 2002. (Philip Pizzica, ANL, 630-252-4847; Walt Pasedag, NNSA, 301-903-3628)

A DOE representative and two PNNL specialists met with Volgodonsk NPP staff to agree upon a detailed work breakdown structure for the Volgodonsk full-scope simulator project. Contracts for the control panels, input and output system, computers, instrumentation and controls, and wiring are in place. The facility for the simulator will be completed by the end of this year and the entire project is scheduled for completion in December 2003.

The Kalinin NPP full-scope simulator, currently assembled for the development stage at the Russian Research Institute for Nuclear Power Plant Operations (VNIIAES), is essentially complete. It includes an advanced core and thermal hydraulic model that VNIIAES developed. The simulator will be disassembled in April 2002 and shipped to the site at Kalinin NPP to be reassembled and site tested. The simulator is scheduled to be ready for training by August 2002.

A technical specialist from PNNL traveled to Russia and Europe for a series of meetings on the Leningrad NPP ISA and EOI projects. The meetings took place in January and February and covered numerous topics.

The Leningrad ISA meeting participants assessed project production, funding, and planned future activities. At a session in late January, the PNNL specialist participated in planning the disposition of the remaining Unit 2 ISA DSA deliverable issues and in clarifying the scope of analysis for the Unit 1 ISA project deliverables. Also discussed was the disposition of a loss of coolant accident frequency sensitivity analysis related to primary circuit integrity (PCI). Leningrad NPP management realizes the importance of resolving international concerns regarding PCI at the earliest opportunity following review of the sensitivity analysis.

Efforts toward completion of the Leningrad EOI project also were discussed at four separate meetings including participants from Leningrad NPP, PNNL, the Kurchatov Institute (KI), a Lithuanian technical service provider, and the Finnish Center for Radiation and Nuclear Safety (STUK). Meeting objectives included clarifying statements of work for initial EOI activities and PNNL providing KI with a list of EOI production tasks. As a result of meeting discussions, the Leningrad EOI project manager requested assistance of the Lithuanian experts during all phases of the EOI project.

A representative from PNNL traveled to Leningrad NPP in early February for the first meeting of the Leningrad Unit 3 & 4 Safety Parameter Display System (SPDS) project team. Project managers from Leningrad NPP have identified a satisfactory area for the assembly of the SPDS. Supplies necessary for the installation were reviewed and Customs paperwork was filed with Rosenergoatom (REA). Factory acceptance tests should be completed in December 2002. Leningrad NPP will begin installation of the Unit 4 SPDS in the fall of 2002. The next outage for Unit 3 will begin in December 2003 and that SPDS project will be completed in spring of 2004.
