Agreement Reached on Organization of Novovoronezh Safety
Assessment. A U.S. program representative met with staff of
Rosenergoatom and Novovoronezh nuclear power plant (NPP) regarding the
safety assessment for Novovoronezh Units 3 and 4. Agreement was reached
about the main organizations involved in the project and their roles;
Novovoronezh NPP will have the technical leadership of the project. Both
organizations have agreed to participate in a planning meeting at Argonne
National Laboratory in December. (Jordi Roglans, ANL, 630-252-3283)
Technical Support Provided for Deterministic Analysis at
Novovoronezh NPP. Two Russian teams, who were at BNL for eight
weeks, have now returned home. One team represented Novovoronezh NPP Unit
3, which is a VVER-230; the other represented Unit 5, a VVER-1000. The
Unit 3 team was successful in constructing a RELAP5 input deck (including
representations of all six coolant loops) and conducting initial
calculations for a small-break loss of coolant accident. The Unit 5 team
used a previously constructed RELAP5 deck to conduct large- and
small-break calculations important for the technical bases for emergency
operating instruction (EOI) implementation. (Greg Slovik, BNL,
Meetings Held with Derzhkomatom and Ukrainian NPPs. The U.S. team
involved in safety analysis projects for VVER reactors in Ukraine met in
Kyiv with representatives from the Ukrainian Com- mittee on Nuclear Power
Utilization (Derzhkomatom) and the Zaporizhzhya and South Ukraine NPPs.
The overall approach for implementing program support to conduct plant
safety evaluations in Ukraine and the organization of the plant-specific
projects were discussed. A steering committee will be formed to provide
overall guidance and oversight for the safety analysis projects in
Ukraine. The committee will include a representative from Derzhkomatom,
a senior management representative from each of the participating NPPs,
and the U.S. program manager for plant safety evaluation. The program
team also met with a senior management representative of Zaporizhzhya
NPP. The approach, scope, and principles of support for plant safety
analysis and requirements for the Zaporizhzhya NPP safety analyses were
discussed. The plant staff will organize a project team for the Unit 5
safety analysis. The project startup meeting will be held in early
December. (Christian Kot, ANL, 630-252-6151)
South Ukraine Unit
1 Safety Analysis Planned. U.S. project members from Argonne National
Laboratory and Scientech, Inc. met with staff from South Ukraine NPP and
their subcontractor, Energorisk, Ltd., in Yuzhnoukrainsk for the first
planning meeting of the South Ukraine Unit 1 safety analysis project.
Project organization and schedules were discussed, and a preliminary plan
was developed with schedules and staffing allocations for the first phase
of the project. The first phase consists of data collection and a level 1
probabilistic risk assessment to determine the probability of core damage
from possible initiating events. The next planning meeting is scheduled
for early December. (Christian Kot, ANL, 630-252-6151)
Khmelnytskyy NPP Trainers Prepare to Implement Refueling Operator Training

Reactor Core Fire Protection Methodology
Document to Be Translated. two Ukrainian fire protection experts will
arrive in the United States November 15 to work with U.S. contractor Burns
& Roe to ensure correct technical terms are used in the Russian
translation of the methodology document. The methodology document was
developed by Burns & Roe and Bechtel National under the direction of a
working group. Final comments from the working group have been resolved
on Draft C. In December, separate workshops are planned in the United
States with executives from Ukraine and Russia, as a step in the adoption
of the methodology as a standard. These executives will meet with
Nuclear Regulatory Commission staff and U.S. utility executives, tour
U.S. power plants that have performed safe shutdown analyses, and receive
training in the use of the methodology. (Rich Denning, PNNL,
Maintenance Advisory Board Meeting Held in
Kyiv. The semiannual meeting of the RBMK Maintenance Advisory Board
was held; all RBMK representatives to the board were in attendance. The
purpose of the meeting was to review the progress of the project since
the inaugural meeting in Charlotte, North Carolina, in February 1996, to
discuss the tasks to be undertaken in 1997, and to develop and sign a
protocol outlining project actions for FY 1997. Each member thanked the
U.S. team for the tangible assistance that this project had provided in
the past year. The members also related the positive benefits provided by
the project to the maintenance of their facilities and praised the
effectiveness of training on the laser and mechanical shaft alignment
systems provided at the Smolensk Training Center.
concluded with signing a protocol that outlines project activities for FY
1997 and made some specific comments on the progress and the members'
opinions of the project. A brief description of these points from the
- The members stated that they approve of the
Project Management Plan.
- Taking into account the importance that
improving maintenance technologies and practices has on enhancing the
safety of overall plant operations, they propose to request additional
funding for this project in FY 1997 to ensure a comprehensive solution of
issues related to safety provided by the transferred maintenance
technologies and training.
The overall impression resulting
from this meeting is that of a truly cooperative effort between
like-minded individuals sharing a common goal -- the improvement of
maintenance at the RBMK plants to enhance safety. The meeting was
conducted in a cooperative atmosphere that demonstrates the maturity of
the project and the true understanding of the overall project goal. (Tom
Vehec, PNNL, 509-372-4072)

Workshop Held on VVER Probabilistic Risk
Assessment Model Assumptions and Data. A workshop sponsored by the
U.S. and jointly organized with the International Atomic Energy Agency,
"Harmonization of VVER PRA Model Assumptions and Data," was held in Rez,
Slovakia. Participants from the Czech and Slovak Republics, Hungary,
Russia, and Ukraine discussed differences in approaches of existing VVER
probabilistic risk assessments (PRAs). Participants from Kola and
Novovoronezh NPPs, with PRAs in their early stages, also had the
opportunity to learn from completed PRAs about key assumptions and their
impact on the results. The main topics addressed included loss of
coolant accident frequencies, success criteria, pump filter clogging, and
component reliability data. Participants suggested that another workshop
should be held in the spring to address human reliability and common
cause failure modeling in the VVER PRAs. (Jordi Roglans, ANL,
Regulators, VVER NPP Representatives Discuss
Common Issues. A VVER emergency operating instruction (EOI)
Regulatory Workshop was conducted at the NRC Technical Training Center in
Chattanooga, Tennessee. Attending were representatives of regulatory
organizations from six nations and their VVER NPPs. This workshop
covered the basic strategies of symptom-based EOIs using the Trojan NPP
control room simulator, a computer-driven, full-scale model of an NPP
near Portland, Oregon, that was shut down recently. Using computer
models, the instrumentation operates in a real-time environment; accidents
can be simulated and operators perform recovery actions. Program
representatives demonstrated the use of the EOIs during simulated control
room emergency conditions. Other topics discussed were validation without
a simulator, basics of EOI analytical calculations, history of EOI
development in the United States, the relationship between the regulator
and the group, and the role of the regulator during the approval process.
This workshop is the first time representatives responsible for
review and approval of the EOIs from Russia, Ukraine, and Eastern Europe
have met to discuss common issues. The workshop provided a venue for the
representatives to learn more about EOIs, share ideas, and discuss
"lessons learned." It also was an opportunity for the regulators to
learn from U.S. industry experts. The regulators were excited about the
opportunity to interface with their NPP representatives.
regulators were united in their evaluation of the significance and benefit
of this meeting. The program received a written request (signed by all
regulatory representatives) for future assistance concerning regulatory
issues for EOIs, operator licensing, onsite inspections, operator
training, NPP licensing, and other issues. As a result, a follow-up
workshop has been scheduled tentatively for February 1997. (Kent Faris,
