Activity Report

August 16, 1996
Prepared by Pacific Northwest National Laboratory, Richland, Washington


RUSSIA

Novovoronezh Safety Analysis. Two groups of NPP staff from Novovoronezh will arrive at BNL on September 1, 1996, to train and perform safety analysis calculations. One group will be using the NPA input decks for Unit 5 while the other group will begin developing an input deck for Units 3 and 4. BNL is preparing for them by setting up the agenda and training materials that will be needed during their stay. (Greg Slovik, BNL, 516-344-7983)

VVER-1000 Working Group Meeting. The VVER-1000 Emergency Operating Instruction (EOI) Working Group met this week in Moscow. The meeting, hosted by VNIIAES, was held to coordinate the NPP activities with those of Gidropress and review the analytical calculations being performed by Gidropress in support of the EOIs. Results of this meeting will be reported following receipt of the meeting protocol. (Kent Faris, PNNL, 509-372-4068)

UKRAINE

Chornobyl Shelter Project. The kickoff meeting was held in Washington, D.C., on August 13 with the team of industrial specialists tasked to support working groups of the European Commission (EC) Chornobyl Shelter project. The meeting included specialists from Bechtel, Halliburton NUS, Parsons Power, SAIC, and Stone & Webster Engineering Company plus INSP staff. The working group coordinator, from Stone & Webster, left the meeting bound for Darmstadt, where he will provide on-site support to the EC project manager, Trischler and Partner. Most of the team will attend an organizing meeting in Darmstadt the week of August 19. That meeting will be followed immediately by working meetings at the offices of the working group team leaders in France, Italy, Great Britain, and Spain. (Dennis Kried, PNNL, 509-375-2170)

South Ukraine Unit 3 Full-Scope Simulator. Contract negotiations between PNNL and S3 Technologies for the U.S.-funded tasks were concluded on August 13. (Narinder Tutu, BNL, 516-344-4929, or James Anderson, PNNL, 509-372-4721)

CENTRAL AND EASTERN EUROPEAN COUNTRIES

Ignalina NPP Configuration Management Project, Lithuania. Three Ignalina NPP staff received training at the Comanche Peak and North Anna nuclear plants in configuration management establishment and use. All three, who manage the configuration management effort at their plant, stated that the training greatly improved their understanding of how to institute and use configuration management. Following the plant visits, meetings were held at Stone & Webster Engineering Company offices. Agreements were reached on how to complete the initial configuration management project and coordinate the U.S. and Swedish joint project on configuration management implementation. (Dan Couch, PNNL, 509-372-4591)

Kozloduy NPP, Bulgaria. On August 7, a shipment of spare parts/consumables was delivered to the Kozloduy NPP for the portable diesel generator supplied earlier under the program. This represents the last deliverable to be shipped for this project. (Bob Fitzpatrick, 516-344-7204)

Nuclear Plant Analyzer Project ( Bulgaria). A research scientist from the Bulgarian Institute for Nuclear Research and Nuclear Energy is at BNL working on the nuclear plant analyzer (NPA). To check out the NPA deck that has been developed for Kozloduy Unit 6, the NPP staff has requested that several transients related to the EOI development be preformed. A transient in which a single pressure relief valve is stuck open in the pressurizer is being analyzed. Discussions with the Kozloduy NPP are under way to obtain the latest procedures for the operators to follow for the calculations. The results will be used by the power plant for their review and feedback into the EOIs being developed for their VVER -1000 reactor. (Greg Slovik, BNL, 516-344-7983)

Lithuania. Two Lithuanian specialists from the Lithuanian Energy Institute (LEI) have completed the section of their BNL training in which the geometrical and operational information on the RMBK-1500 reactors at Ignalina has been discussed. A list of missing information has been compiled for them to investigate when they return to Lithuania. The available data is now being used to develop input decks to perform some cell calculations for the different fuel types in the core. The ultimate goal is to develop the reactivity feedback models needed to enhance the nuclear plant analyzer that LEI uses for thermal hydraulic calculations. (Greg Slovik, BNL, 516-344-7983)

Slovakia Nuclear Plant Analyzer. A training program date is being discussed with the power plant and the regulators. The proposed time is during November 1996. The material needed for the training is being developed. (Greg Slovik, BNL, 516-344-7983)

Ignalina NPP Workshop. An emergency operating instructions (EOIs) workshop, specific to the Ignalina NPP site, was conducted August 6 through 9 at the RELCON offices in Stockholm, Sweden. Participants included representatives from RELCON (Sweden), Ignalina (Lithuania), and PNNL. Major meeting topics included a project status review, discussion of basis document requirements, and comparison of probabilistic risk assessment (PRA) results to EOI strategies.

Selected PRA-identified accident sequences were used to assess the completeness of the current EOI guidance. Several important EOI limitations were identified and corrected. Overall, the assessment demonstrated that the Ignalina NPP EOIs provide valuable guidance to assist the plant's operators in responding to abnormal and emergency plant conditions. Future workshops will involve the continued use of dominating accident sequences in assessing the adequacy of the EOIs.

The PRA importance analysis of basic individual events was reviewed and discussed with regard to EOI development. Specifically, those basic events that involved operator performance and provided the highest fractional contribution to the core damage frequency were reviewed. Although not complete, the Ignalina NPP EOI staff plans to conduct a comprehensive importance analysis, to identify important operator performance issues that must be addressed in the EOIs before the first complete EOI draft is issued.

In support of the need to develop a basis document, PNNL stressed the need to involve a design representative in future meetings. PNNL agreed to contact ENTEK concerning this issue at the upcoming RBMK working group meeting. (Sam McKay, PNNL, 509-372-4059)
