Activity Report

December 6, 1996
Prepared by Pacific Northwest National Laboratory, Richland, Washington


RUSSIA

Balakovo Trainers Implement Water Chemistry Training Course. A team from U.S. contractor Sonalysts, Inc. worked with personnel from Balakovo Nuclear Power Plant (NPP) to implement the pilot training course for water chemistry personnel. The course was presented over four days and included both classroom and laboratory training sessions. (Sonja Haber, BNL, 516-344-3575)

CHORNOBYL SHELTER PROJECT

Working Group Discusses Chornobyl Shelter Project. U.S. experts and contractor Stone & Webster Engineering Company, coordinator of the U.S. European Commission Project team, participated in meetings in Paris and Slavutych to review the results and recommendations of the Chornobyl Shelter Project. The G-7 Nuclear Safety Working Group conducted the meeting in Paris; the Chornobyl Shelter Manager chaired the meeting in Slavutych, which was attended by representatives of several Ukrainian ministries and institutes, including the Ukrainian Nuclear Regulatory Administration.

The consensus on short-term measures is that they are appropriate and should be implemented quickly. Consen- sus was not reached on long-term measures, largely due to the complexity and funding issues associated with the Ukrainian position that removing fuel-containing masses must proceed as soon as possible. The U.S. team proposed a process for developing implementation, finance, and management plans, including a proposal to initiate early starts on appropriate short-term measures. (Dennis Kreid, PNNL, 509-375-2170)

New Equipment Will Monitor Criticality Safety. U.S. technical experts discussed the criticality safety of fuel debris in the Shelter with representatives from the Chornobyl NPP, Khlopin Radium Institute, and VNIPIET. Participants reached agreement on specifications for monitoring equipment that will provide real-time indications of fuel debris neutronic characteristics. (Dennis Kreid, PNNL, 509-375-2170)

CENTRAL AND EASTERN EUROPE

Technical Support Given for Bulgarian Emergency Operation Instructions Development. A report summarizing the predicted results from applying the RELAP5 computer code to an accident scenario for Kozloduy Unit 5 (VVER-1000) has been transmitted to the Kozloduy emergency operating instruction (EOI) team. The accident scenario is a trip of all four main coolant pumps, with SCRAM, and the transition of the plant to natural circulation conditions. The Kozloduy plant staff requested the predicted response to this accident sequence to support their ongoing EOI development and establishment of a technical basis. The Kozloduy EOI team requested that their technical expert resident at Brookhaven National Laboratory conduct an additional two transient calculations related to specific EOIs.

CROSS-CUTTING ACTIVITIES

Consultancy Meeting Held in Richland. International Atomic Energy Agency (IAEA) consultants met with Program staff of Pacific Northwest National Laboratory in Richland, Washington. The meetings focused on sharing United States experience in establishing spent fuel dry storage temperature limits accepted by the U.S. Nuclear Regulatory Commission. A second aspect of the meeting was COBRA-SFS Code training for Hungarian and Ukrainian staff members. The COBRA-SFS Code predicts spent fuel temperatures in dry storage. Both activities support IAEA programs that were developed on the recommendation of the IAEA-coordinated Association of VVER Regulators that involves ten countries including the U.S.

The U.S. efforts on developing dry storage criteria for Zircaloy-clad spent fuel are expected to help refine an experimental program sponsored by IAEA. VNIPIET will characterize the performance of Zircaloy 1% niobium cladding used for VVER fuel. The IAEA will distribute information from the study to countries, reactor operators, and regulatory agencies needing it to qualify dry storage technologies. An IAEA program makes the COBRA-SFS code available to all VVER reactor operators and regulators. This will help reactor operators and regulators predict storage temperatures in proposed dry storage facilities. IAEA has contracted with Hungary to make necessary modifications to the COBRA-SFS code to better model the hexagonal VVER fuel assemblies. (Mikal McKinnon, PNNL, 509-372-4198)
