Leningrad Plant-Specific Safety and Risk Analysis. Representatives from INSP met on July 3 and 4 with the Research and Development Institute of Power Engineering (RDIPE) to finalize the statements of work for the Leningrad Plant-Specific Safety and Risk Analysis. The effort is a multilateral cooperative agreement. Sweden and the United Kingdom are funding a probabilistic risk assessment (PRA) of Leningrad Unit 2; the United States is providing the necessary deterministic analysis, system descriptions, and selected system engineering assessments to support the PRA. Project objectives are to assess the impact of recent safety improvements to Leningrad Unit 2 and to establish a common perspective pertaining to RBMK severe accident risk and mitigation.
Before the meeting, U.S. participants had prepared and proposed to RDIPE detailed statements of work and examples of expected deliverables, costs, and schedules. With minor changes, the work statements were agreed to by all parties and RDIPE agreed to begin activities in August 1996. PNNL will revise the detailed work scopes and RDIPE agreed to prepare a fixed-price proposal consistent with the agreements reached in Vienna in April 1996. All agreements and work activities have been integrated with PRA needs schedules, and requirements. (Gary L. Smith, PNNL, 509-375-4482; Sam McKay, PNNL, 509-372-4059)
Novovoronezh Safety Parameter Display System. Burns and Roe has issued a request for proposal for a U.S. vendor for the safety parameter display system (SPDS) for Novovoronezh Unit 3. The proposals will also include options for additional SPDS units for VVER-440/230 and VVER-440/213 plants. The U.S. vendor will work with and transfer technology to the Russian firm ConSyst. In addition to providing an SPDS for the Novovoronezh plant, a developmental unit will be provided to ConSyst for use in developing displays and making future upgrades of the system.

Plant Safety Evaluation Sites. A July 1, 1996, letter from N. Nigmatullin of Derzcomatom, the Ukrainian State Committee on Nuclear Power Utilization, notified the International Nuclear Safety Program that lead reactor units have been selected for the in-depth plant safety evaluations in Ukraine. Zaporizhzhya Unit 5 will represent the VVER-1000/320 reactor series. The South Ukraine NPP Unit 1 is designated as the lead unit for earlier versions (V-302 and V-328) of VVER-1000 reactors. To implement the probabilistic risk assessment for Zaporizhzhya Unit 5, a U.S. contractor will be selected to provide project management and technical expertise. After the contractor is selected, an early September meeting with Derzcomatom is planned in Kyiv to begin the project. (Christian A. Kot, ANL, 708-252-6151)
Training Activities at Khmelnytskyy NPP. During the period June 24 through 28, General Physics personnel held a working session at the Khmelnytskyy NPP. Khmelnytskyy staff have increased the number of full-time instructors at the training center from 3 to 19. They continue to meet milestones for the development of the Refueling Floor Operator, Chemical Operator, and Control Room Reactor Operator training courses. During the working session, Khmelnytskyy staff provided two sets of deliverables for technical review. (Sonja Haber, BNL, 516-344-3575)
Probabilistic Risk Assessment Training. Scientech, Inc., has completed 3 weeks of PRA training in Kyiv for Ukrainian participants. From June 10 to June 14, Scientech presented an overview course on PRA methods and principles at the Energoprojekt Kyiv Institute. A 2-week training workshop (June 17 to June 28) on computational methods in PRA followed. In addition to familiarizing the Ukrainian participants with the IRRAS computer code, the workshop covered practical aspects of failure mode and effects analysis, human reliability analysis, development of fault and event trees, selection of success criteria and initiating events, and risk screening. Participants in the courses included staff from the Energoprojekt Institutes (Kyiv and Kharkiv), the Nuclear Research Institute, and the South Ukraine, Rivne, and Zaporizhzhya NPPs. (Christian A. Kot, ANL, 708 252 6151)
RELAP Training for Ukrainian Analysts. A RELAP workshop for nine Ukrainian analysts was held at Argonne National Laboratory (ANL). Nodalization schemes were completed for the important subsystems of a VVER-1000, i.e., the reactor vessel, the primary system and secondary system, including the steam generator. Generic data from the literature as well as plant-specific data (South Ukraine Unit 1) were used in the modeling. Missing data were identified. Emphasis in the workshop was on the preparation of validated input decks. The objective was to prepare and check out a RELAP input-deck/model based as much as possible on plant-specific data for a VVER-1000 reactor in Ukraine. (Christian A. Kot, ANL, 708 252 6151)
CENTRAL AND EASTERN EUROPEAN COUNTRIES
Ignalina NPP. A task order was issued to Halliburton NUS to develop a project work plan and schedule for the replacement or upgrade of qualified, state-of-the-art instrumentation and control modules with superior reliability at the Ignalina NPP. Meetings are scheduled for the week of July 15, 1996, in Vilnius, Lithuania. (Andrea L. Fernandez, PNNL, 509-375-2649)
ESREL 96 - PSAM III CONFERENCE. PNNL attended, as a presenter, the PSAM III conference, June 24 through 28. The conference represented the merging of two major risk-based technical conferences: the European- based ESREL conference and the U.S.- based PSAM conference. The conference objective was to promote communication about experiences and relevant applications of system-based approaches to improve design and operation of technological systems. The PNNL paper, "Application of Risk Assessment Results in the Development of RBMK EOIs," addressed the combined activities of the U.S. Department of Energy and Swedish SIP-funded projects to develop emergency operating instruction (EOIs) for the Ignalina NPPs (Soviet-designed RBMK systems in Lithuania). Western international interest appears to focus on reducing the risk presented by the continued operation of Soviet-designed reactor systems in neighboring countries. Panel members repeatedly expressed concern about the uncertainty of available assessment results and reiterated the international community's desire to continue supporting activities aimed toward better understanding the design and operation of Soviet-designed reactor systems. Three-hundred sixty-three technical papers were presented at the conference, held in Crete, Greece. (Sam McKay, PNNL, 509-372-4059)
