Meetings Held on In-Depth Safety Assessment (ISA) Projects for VVER Plants in Ukraine

An ANL technical specialist attended meetings in Kyiv, Ukraine on the in-depth safety assessment (ISA) projects being sponsored at their VVER plants. In particular, a meeting was held to discuss the status and schedule for the ISA projects. The meeting resulted in an updated working schedule for the ISA projects. The working schedule presents the current plans for carrying out the ISA studies by the nuclear power plant project teams and their consultants, and includes the schedule for the project peer reviews. Energoatom (the Ukrainian utility) emphasized that the NNSA safety assessment program has been of great benefit to Ukraine. As a result of this program some subtle safety risks were revealed and some proposed plant upgrades were found to have limited impact on safety. The completion of the remaining ISA tasks will be important to more accurately identify safety needs to prioritize safety improvements. (Mark Petri, ANL, 630-252-3719)

Sixth International Information Forum on Safety Analysis for Nuclear Power Plants of the VVER and RBMK Types (Forum-6) Takes Place in Vienna

Two ANL technical representatives traveled to Vienna, Austria and then to Kiev, Ukraine to help with final preparations and assist in conducting the Sixth International Information Forum on Safety Analysis for Nuclear Power Plants of the VVER and RBMK Types (Forum-6). The meeting was attended by several ANL specialists, a representative from the Idaho National Engineering and Environmental Laboratory (INEEL), and approximately 150 other attendees. The purpose of the meeting was to bring plant, utility, regulatory, and research institute personnel together in an open forum to exchange information concerning past, present, and planned safety assessment work at Soviet-designed reactors.

The INEEL representative chaired sessions devoted to the International RELAP5 Users Group (IRUG) attended by about 40 people and included 17 presented papers. Good discussions were held and the attendees felt that including these sessions as part of the forum was very valuable and should be continued.

An ANL representative chaired the closing session of the forum during which participants made recommendations for future forums. Recommended future forum topics included the regulatory review of safety assessments; internal and external hazard analyses, uncertainty analyses, probabilistic risk assessment applications (including the implementation of risk monitors; safety of staff, the public, and the environment; emergency operating instructions; and severe accident management.

A decision was also made on the best option for SUNPP to use in properly monitoring the Projects nuclear fuel assemblies. The meeting met its objective and the parties were successful in determining and agreeing on a design architecture version for the core monitoring system upgrade.

    UNFQP Regulatory Workshop

    During the week of May 20, 2002, two PNNL technical specialists participated in a Regulatory Workshop on the Ukraine Nuclear Fuels Qualification Project (UNFQP). Prior to the workshop, meetings were scheduled the first two days of the week with, 1) NAEC Energoatom (NAEC) to discuss the Westinghouse Proprietary Agreement, and with 2) the State Nuclear Regulatory Committee of Ukraine (SNRCU) to discuss overall regulatory requirements for the UNFQP.

    The discussions and negotiations with NAEC on the Westinghouse Proprietary Agreement were consummated in a signed unilateral agreement between the two organizations for the protection of proprietary information that will be transferred during the implementation of the UNFQP.

    In the second meeting, one of the PNNL specialists met separately with the Head of SNRCU and a colleague to participate in discussion of the envisioned regulatory process for the UNFQP. The Head of SNRCU started the discussion with a commitment to have the State Scientific and Technical Center (SSTC) work closely and openly with Westinghouse to facilitate an effective and timely SNRCU regulatory approval/concurrence process during the implementation of the UNFQP. He also requested that NAEC immediately submit the Concept Technical Decision on the entire project to facilitate the beginning of the regulatory process with SNRCU.

    The Regulatory Workshop on UNFQP was held during May 22 24, 2002. Presentations and discussions were held between SNRCU, Ministry of Fuel and Energy (MF&E), NAEC, Center for Reactor Core Design (CRCD), South Ukraine NPP, SSTC, DOE, PNNL, and Westinghouse. A focus of the meetings was the need for NAEC to immediately submit the Concept Technical Decision on the project to SNRCU. SNRCU agreed that the submittal of this key licensing document should not await the approval of the revised Work Implementation Schedule.

    Project Construction Management Group - Status of Heat Plant Commissioning Discussed

    A technical specialist from PNNL traveled to Kyiv and Slavutych, Ukraine in late April and again in late June, 2002. The specialist met with the manager of the Project Construction Management Group (PCMG) in Ukraine to discuss the status of Chornobyl Nuclear Power Plant (ChNPP) replacement heat plant commissioning and final spare parts orders.

    All hot water and steam boilers have been commissioned on natural gas but are just now being cleared for Mazute. A mazute test on one boiler was conducted in May and revealed a problem with the burner atomizers that must be corrected before commissioning on Mazute can be completed. The First Deputy General Direct of ChNPP indicated that the individual boiler tests on Mazute would be accomplished after the burner atomizers are modified and the comprehensive tests would occur in fall 2002 when there is a sufficient heat load.

    All remaining spare parts should be received by the end of June 2002. Discussions also took place on the feasibility study performed by Energoprojekt on the use of excess steam and natural gas capacity for producing electrical power for ChNPP infrastructure usage using steam and/or gas turbines.

    The PNNL technical specialist toured the heat plant site to observe progress since December 2001 and met with the Startup and Adjusment General Contractor Management and reviewed status and completion of their subcontract. Both subcontracts involving the U.S. contributions and the General Contractor are complete and being closed out. (James Hartley, PNNL, 509-372-4428)

    Design Document System Managment and Other Ukraine Projects Discussed

    In mid-May 2002 a representative from PNNL attended a Ukraine reliability database (URDB) seminar in Yalta, Ukraine. Representatives from the primary host-country vendor, Information and Technologies Ltd. (INIT); utility, Energoatom; each of the nuclear power plants (NPPs) in Ukraine; and various other interested parties attended and provided presentations. The PNNL specialist chaired the second days session and presented information on a reliability database use in the United States. The Ukrainian NPPs are now fully engaged in directing the future use of the URDB. A few issues remain, however, these as well as other feature and capability concerns are expected to be resolved using the Energoatom-led URDB working group.

    Following the seminar, the representative from PNNL traveled to Kyiv and met with utility and vendor representatives on the design document system management (DDSM); the event analysis, reporting, and lessons learned (EARLL); Ukraine Quality Assurance (QA); and Ukraine Infrastructure projects. Specific issues were reviewed and statements of work for near-term activities were developed for all four projects. (Tyrone Blackburn, PNNL, 509-372-4092)

    Ukraine Code Support Project Representatives Meet

    Two meetings essential to the Ukraine Code Support Project took place in May in Kyiv, Ukraine. An ANL technical specialist conducted the meetings while a second ANL representative participated.

    The first of two meetings was a Ukraine code support planning meeting between ANL, The International Chornobyl Center (ICC) Safety Analysis Laboratory (SAL), the Laboratory for Engineering Research and Technology (LERT), and the Institute for Electric Power research in Budapest, Hungary (VEIKI). These organizations will provide responses to requests from Ukrainian NPPs for support with usage of the MELCOR and CONTAIN computer codes. Decisions were made on how to formally handle requests for support and responses. All requests and responses will be entered into a MELCOR/CONTAIN Code Support web page for future reference.

    The second meeting was a Ukraine Code Support Project Meeting involving ANL, SAL, LERT, VEIKI, South Ukraine NPP, Khmelnytskyy NPP, Zaporizhzhya NPP, Rivne NPP, and Kyiv Energoprojekt (KIEP). An ANL representative led a discussion during which each NPP described the status of their design basis accident (DBA) analyses, beyond design basis accident (BDBA) analyses, and In-depth Safety Assessments (ISAs), as well as plans involving usage of MELCOR and CONTAIN codes.

    All NPPs requested a workshop on usage and application of MELCOR plus advice on South Ukraine NPP staff who will work on extending their MELCOR 1.8.3. input deck to BDBAs at the workshop. The workshop is tentatively scheduled to be held in Kyiv at the Kyiv National Taras Shevchenko University (KSU), September 2 6, 2002.
