Activity Report

October 4, 1996
Prepared by Pacific Northwest National Laboratory, Richland, Washington


RUSSIA

Installation Rescheduled for Safety Parameter Display System at Kursk Plant. Meetings were held on September 18 and 19 between representatives from Parsons Power and personnel from RDIPE, Moscow Atomnergoproek (MAEP), VNIEM, Kursk nuclear power plant (NPP), Gosatomnadzor (GAN), and Rosenergoatom (REA) to resolve technical issues and align roles and responsibilities. Software development was observed on the developmental safety parameter display system and is proceeding at a reasonable pace. System installation was to occur during the scheduled maintenance outage in November 1996. However, that outage has been canceled. Cancellation of the outage has resulted in a schedule delay of at least 6 months for system installation. However, special procedures, approved by GAN, will be developed so that most of the installation can be performed during normal plant operation preceding the rescheduled outage. This phase of the installation is scheduled to begin in early December 1996 and last about 2 months. The schedule delay at Kursk NPP will not impact the installation schedules of the remaining RBMK safety parameter display system projects. (Norman Fletcher, DOE, 301-903-3275)

Quality Assurance Workshop Held in Moscow. Quality assurance measures related to the transportation of nuclear materials and spent fuel was the topic of a recent workshop held at Gosatomnadzor (GAN) headquarters in Moscow. During the workshop, representatives from the U.S. Department of Energy (DOE) Brookhaven Area Office, two DOE national laboratories, General Electric Company, and the Illinois Department of Nuclear Safety shared technical information on U.S. techniques for ensuring the quality of nuclear materials packaging and transport. Participants also took a field trip to the fuel manufacturing facility at Electrostal to inspect new fuel packaging and observe transportation techniques. The GAN workshop was one of a series of technical exchanges being held as part of the U.S. program's nuclear safety legislative and regulatory framework element. (Jan van Erp, ANL, 630-252-3193).

UKRAINE

Full-Scope Simulator Project Moving Ahead at Khmelnytskyy NPP. Control panel modification and refurbishment have been completed at the facilities of Energotraining. Most of the panels have been delivered to the plant site and are being installed inside the training center. S3 Technologies has shipped the computer complex to Khmelnytskyy NPP along with the input/output devices. The S3 Technologies hardware installation team will arrive at the plant on October 8, 1996, to start the integration effort. (Peter Kohut, BNL, 516-344-4982)

CHORNOBYL SHELTER PROJECT

Chornobyl Shelter Project Leaders Conduct Briefing. U.S. scientists and industry specialists from the Chornobyl Shelter Project met in Washington, D.C., to brief DOE managers on project activities and issues. The briefing was in preparation for the DOE staff trip to Ukraine and St. Petersburg planned for mid-October (see Planned Activities). (Dennis Kreid, PNNL, 509-375-2170)

CENTRAL AND EASTERN EUROPE

Slovakia: V1 Simulator Upgrade Project Achieves Milestone. Two program staff members completed 2 weeks of technical assistance to the simulator support staff at VUJE in Trnava, Slovakia. Computer terminal displays were developed and implemented on the instructor terminal and the six trainee stations. This equipment is part of the simulator upgrade project being conducted for the Bohunice NPP V1 block (two VVER-440/230s) at VUJE. At least one display per station was tested successfully. A major milestone was reached the instructor now can simulate changed conditions on individual systems at the console, and the respective trainee can respond to the perturbation at the remote console. (Bill Shier, BNL, 516-344-2385)

CROSS-CUTTING ACTIVITIES

Information Exchange on NPP Safety Assessment Techniques Yields Insights. On September 24-27, 1996, an information exchange was held at the Institute of Physics and Power Engineering in Obninsk, Russia. The forum, "Analytical Methods and Computational Tools for NPP Safety Assessment," covered topics related to the analysis methods and computational tools used in safety assessments of Soviet-designed reactors. Approximately 75 specialists attended, representing Canada, Czech Republic, Bulgaria, France, Germany, the International Atomic Energy Agency, Lithuania, Russia, Slovakia, Sweden, Ukraine, United Kingdom, and the United States. Ten NPP sites with Soviet-designed reactors were represented. Participants presented 38 papers on topics related to the safety assessment of Soviet-designed reactors.

The forum provided unprecedented overview and insight into the broad scope of activities underway in the area of Soviet-designed-reactor safety assessment. Participants shared the results of their countries' programs carried out both with and without international assistance. The open exchange of information was particularly valuable for the participants from the host-country NPPs.

The presentation describing the PRA work indicated that operator actions and component reliability dominated the risk spectrum for the VVER reactor type. However, it was made clear that much work needs to be done with regard to developing consistent modeling assumptions for VVER PRA work. The need for developing a robust reliability database for use in PRAs is high. With regard to deterministic analysis, it is apparent that much development work is needed to upgrade host-country computational tools or apply more modern ones.

A full report documenting the information exchange forum is planned. (Jeff Binder, ANL, 630-252-7265)

VVER-440/230 EOI Working Group Meets, Shares Progress. representatives from Armenia Nuclear Power Station and Kozloduy, Novovoronezh, and Bohunice NPPs met with VNIIAES and U.S. representatives at Kozloduy NPP on September 23 through 26. Four newly drafted and two revised Kozloduy NPP emergency operating instructions (EOIs) were discussed. Because Kozloduy NPP had not adopted an EOI Writers' Guide, some problems were found with these instructions. Additional workshops were planned to assist Kozloduy in resolving this issue. Kozloduy working group members also announced their plan to complete the first draft of 22 of the 32 EOIs by December 2, 1996.

Novovoronezh staff reported that the first drafts of five of the remaining 10 EOIs for their plant have been completed. Calculations concerning integrity and voids in the reactor core remain to be completed.

Armenia nuclear power station staff continued to state their intent to draft symptom-based EOIs. The station has requested introductory EOI training courses and Russian and U.S. EOI documents for reference. The Armenian representative noted that a formal plan for EOI development will be completed in the next several months. (Kent Faris, PNNL, 372-4068)

Contractor Chosen to Provide Valve Repair Equipment for RBMK Maintenance Technology Transfer and Training Project. A contract was awarded to ECO USA Inc. on September 30, 1996, for in situ valve repair equipment. The equipment will be transferred to host-country NPPs with RBMK reactors. (Andrea Fernandez, PNNL, 509-375-2649)
