Work Begins on Safety Maintenance Project for Bilibino. A new effort to enhance the safety maintenance program at Bilibino NPP got under way in early November. Five maintenance representatives from Bilibino attended an intensive three-day course on low-temperature corrosion. The workshop, presented in Anchorage, Alaska, by U.S. experts, treated a spectrum of issues related to corrosion in cold climates.
After they completed the corrosion course, the Bilibino staff traveled to Richland, Washington, to discuss project implementation strategy with U.S. team managers. After thoroughly examining the full range of maintenance improvement techno- logies available through the project, the group selected a set of goals and technologies and prioritized them for transfer to the Bilibino maintenance department. A formal protocol for project implementation was signed, and work was started to achieve the agreed-upon project deliverables.
While in Richland, the Bilibino group toured the Washington Public Power Supply System=s Nuclear Plant 2 (WNP-2) on the Hanford Site. The tour highlighted the WNP-2 maintenance training department and its practices with respect to the technologies expected to be transferred to Bilibino. During a second tour at Ice Harbor Dam on the Snake River, Bilibino staff observed major maintenance work being performed on one of the dam=s turbine-generators. (Don Jarrell, PNNL, 509-372-4096)

Three Ukraine Plants Active in Transfer of Training Technology. A team of U.S. and Khmelnytskyy NPP training experts recently completed a second work session with training specialists at South Ukraine NPP. The trainers are developing task lists, identifying learning objectives, and reviewing and completing instructional materials for the plant=s Instrumentation and Control course. The plant-specific course at South Ukraine emphasizes use of the Pace7 soldering station in repairing integrated circuit boards.
At Zaporizhzhya NPP, training experts from the United States and Khmelnytskyy NPP are working with Zaporizhzhya training specialists to develop teaching materials for the Chemical Operator pilot training course. In November, the trainers are concentrating on validating lists of operator tasks and reviewing course materials. Work will continue on the development of training material specific to operation of the condensate demineralizers. In late November, a tentative date will be set for course implementation.
Rivne NPP training specialists are working with U.S. and Khmelnytskyy trainers to develop an Instrumentation and Control Technician pilot training course. The Rivne-specific course focuses on differential pressure transmitters. By the end of November, a date for course implementation will be scheduled. (Sonja Haber, BNL, 516-344-3575)
Multi-Assembly Baskets en Route to Ukraine. After receiving copies of the certificates of conformance, the U.S. team shipped the remaining two multi-assembly baskets to Zaporizhzhya NPP. The baskets are integral components of the above-ground spent fuel storage system being constructed for the Zaporizhzhya plant with U.S. support. The baskets are expected to arrive in Ukraine in early December. (Mike McKinnon, PNNL, 509-372-4198)
International Experts Review Expressions of Interest in Early Biddable Projects. In collaboration with representatives of Ukraine and the European Bank for Reconstruction and Development, international experts evaluated the expressions of interest received for the early biddable projects under the Shelter Implementation Plan. The evaluations resulted in short lists of recommended bidders for each of the four early biddable projects. Those lists were provided to the European Bank representative for future action.

Agreement Reached on Funding for Chornobyl Unit 3/4 Ventilation Stack Work. The estimated cost (US$1.8 million) to repair the Chornobyl Unit 3/4 ventilation stack was finalized on November 12 in negotiations with Chornobyl Shelter representatives. It was agreed that the United States will fund $1 million of the work while Canada will cover the other $800 thousand. In addition, Ukraine will contribute approximately $500 thousand to the work beyond the $1.8 million cost of the contracted work. Signing of the actual task order is anticipated during the week of November 17, pending Shelter management final review and approval of the payment schedule. Actual repair work during the remainder of 1997 is unlikely because of the onset of winter weather and associated personnel safety considerations. However, orders will be placed before the end of December for the material delivery system, mockup materials, and actual replacement bracing. (John Schmidt, PNNL, 509-372-6377)
Prototype Monitoring System en Route to Chornobyl Shelter. The neutron monitoring system developed by U.S. experts for use in the Chornobyl Shelter was shipped to Ukraine on November 14. It is scheduled to arrive in Odessa on December 21. The system is designed to determine whether the high neutron count rate in some parts of the Shelter is indeed caused by fission reactions. If so, the system will serve as a prototype for a more permanent monitoring system to be produced under international funding as part of the work described in the Shelter Implementation Plan.

VVER-1000 Working Group Discusses EOI Analysis Results and Future Work. The working group for VVER-1000 emergency operating instructions (EOIs) met during the last week of October at Kozloduy NPP to discuss EOI analysis results and define plans for future EOI development activities. Participants included representatives of Balakovo, Kozloduy, Zaporizhzhya, Temelin, and Khmelnytskyy NPPs. Also in attendance were representatives from VNIIAES, Rosenergoatom, Gidropress, the Kurchatov Institute, Atomenergoproekt, and both the Moscow and Atlanta offices of the World Association of Nuclear Operators. U.S. team members from Science Applications International Corporation (SAIC) and Pacific Northwest National Laboratory also participated.
Gidropress specialists presented results of their analyses for five scenarios involving loss-of-coolant accidents of differing sizes. The associated calculations had been completed using Russian computer codes and contained no equipment failures or operator actions. As such, they resembled calculations for a safety analysis rather than those for validating EOI methodology. Gidropress reported that the calculations lacked the technical accuracy demanded for EOI calculations because of the limited-capability computer codes and hardware used to perform them.
In response to Gidropress= report, the SAIC representative provided an expanded explanation of the EOI analysis process and answered many questions from the group concerning EOI analysis methodology. In addition, the U.S. team scheduled additional workshops to provide site-specific technical assistance on EOI analysis to specialists from Kozloduy, Zaporizhzhya, and Balakovo NPPs. These workshops will be presented to regulatory, analytical, and NPP representatives over the next two months. Representatives of the NPPs, analytical organizations, and the U.S. team agreed to better define the purpose and scope of the EOI analysis activities for each of the NPPs and confirm plans for completing the work.
Group members from Temelin NPP reported on their activities and recommendations related to preparing EOIs with the assistance of Westinghouse Electric Corporation specialists. Khmelnytskyy NPP representatives indicated their intent to evaluate the need to develop symptom-based EOIs for their plant.
At the meeting, it was noted that Kozloduy NPP staff have completed the first deliverable for the EOI contract for their VVER-440/230 units. This deliverable consists of a plan for completing the VVER-440/230 EOIs and supporting analysis as well as agreements of support from the Bulgarian regulatory agency and analytical support organizations.

RBMK Plant Maintenance Staff Train on New Equipment. Twenty representatives from the five participating RBMK reactor sites (Chornobyl, Kursk, Ignalina, Smolensk, and Leningrad NPPs) spent the last two weeks of October in Desnagorsk, Russia, training on the use of specialized safety maintenance equipment. The course included classroom instruction at the Smolensk Training Center and hands-on training at Smolensk NPP. Classroom topics included database setup and configuration control, analysis of individual data including trending, and diagnostic evaluations. Hands-on training concentrated on using the new equipment for data collection, evaluation, and analysis of the vibrational condition of actual operating rotating equipment in the Smolensk Training Center and Smolensk NPP.
U.S. specialists presented the training using the vibration monitoring and analysis equipment systems supplied by U.S. contractor SKF Condition Monitoring. Each of the five RBMK sites has been provided four of the systems as part of the U.S. team=s maintenance technology transfer and training project for RBMK plants. The new systems will enable plant maintenance personnel to collect data on shaft acceleration and velocity, in addition to displacement, on numerous safety-grade pumps and equipment. The new systems are capable of completely analyzing and storing historical data as well as performing trending and diagnostic evaluations of all equipment monitored.
