Activity Report

for the period April 19 through May 2, 1997
Prepared by Pacific Northwest National Laboratory (PNNL), Richland, Washington


Russian Training Technology Transfer Group Plans 1998 Work. U.S. and Russian personnel associated with the Russian effort to transfer training technology met in Phoenix, Arizona, on April 23 through 29. The group discussed and assigned priorities to planned program activities, with emphasis on fiscal year 1998. Participants also toured Palo Verde nuclear power plant (NPP) and its training facilities. Both the Russian and American participants agreed upon and signed a meeting summary that identified commitments and action items. (Sonja Haber, BNL, 516-344-3575)

Gosatomnadzor Staff Attend U.S. Safety Analysis Workshop. In mid-April, ten representatives from Gosatomnadzor participated in a workshop at Oak Ridge National Laboratory that focused on safety analysis for research reactors and fuel cycle facilities. Presenters shared their experience gained in the preparation and review of safety analyses for the High Flux Isotope Reactor at Oak Ridge and gaseous diffusion plants at Portsmouth, Ohio, and Paducah, Kentucky. Participants toured the High Flux Isotope Reactor and related facilities. (Ed Branagan, DOE, 301-903-6509; George Vargo, PNNL, 509-375-6836)


Simulator Verification and Validation Workshop Held. During the week of April 7, staff from Khmelnytskyy and South Ukraine NPPs and the Engineering Technical Center in Kyiv participated in a workshop on the verification and validation process for nuclear power plant simulators. The workshop, presented at Brookhaven National Laboratory by U.S. specialists, covered seven major topics: experience of U.S. utilities in full-scope simulator verification and validation; verification tasks during simulator purchasing; human factors related to simulator fidelity during testing; methodology for validating simulators; scenarios for transients; evaluation of acceptance test results; and a step-by-step verification and validation procedure. The participants agreed that the workshop should be presented next at Khmelnytskyy NPP to a wider audience comprising staff from Khmelnytskyy, South Ukraine, Rivne, and Chornobyl NPPs. (Peter Kohut, BNL, 516-344-4982)

Chornobyl Staff Complete Training Course. Representatives from Chornobyl NPP participated in a 15-day training course at the General Physics facility in Aiken, South Carolina. The course presented a two-day overview of the Systematic Approach to Training and a week-long session on the fundamentals of instructor training with a discussion of developing learning materials for on-the-job training. Participants spent the final week developing instructional materials for the Control Room Reactor Operator course, which will be implemented in late 1997. (Sonja Haber, BNL, 516-344-3575)

Safety Parameter Display System Request for Proposal Issued. On April 18, the U.S. team issued a request for proposal to prospective bidders on safety parameter display systems planned for two NPPs in Ukraine. Installation of the systems--one each for Zaporizhzhya Unit 5 and Khmelnytskyy Unit 1--is planned for the spring outages of 1998. Bids must be returned by May 19. (Mike Durst, PNNL, 509-372-4968)

Startup Meeting Held for Khmelnytskyy NPP Safety Assessment. In April, U.S. team members and staff of Science Applications International Corporation met with representatives from Khmelnytskyy NPP to discuss the start of a plant-specific safety assessment. The American representatives introduced the approach and structure of U.S.-supported plant-specific safety analyses to key personnel at the plant, including the general director and the deputy chief engineer of safety.

The plant team discussed the Ukrainian requirements for completion of an in-depth safety assessment (ISA) and the Ukrainian utility industry plan to meet those requirements. The plan calls for completing an ISA for three lead plants in Ukraine and then extending the results to the remaining units. The lead unit for VVER-1000 Series 320 reactors is Zaporizhzhya Unit 5. Khmelnytskyy NPP's reactor is of the same series. Khmelnytskyy representatives expressed concern regarding the extent of applicability of the Zaporizhzhya study to Khmelnytskyy because of design differences between the two plants.

To address this concern, it was agreed that, at a minimum, a plant-specific data collection and system description activity would be initiated for Khmelnytskyy NPP so the Zaporizhzhya study results can be compared appropriately to the Khmelnytskyy plant. During the meeting, the U.S. team presented a draft technical work scope for carrying out the data collection and system description effort. Khmelnytskyy representatives are expected to respond by May 15, 1997. (Jeff Binder, 630-252-7265)


Ukraine Accepts Shelter Implementation Plan. The working group for the Shelter Implementation Plan met on April 21 in Kyiv with the G-7 and on April 22 in Slavutych with the G-7 and Ukrainian government representatives. The G-7 concurred with the Shelter Implementation Plan and subsequently provided guidance to clarify a number of key issues (primarily the need for a new shelter and a reduction of the degree of stabilization). In the meetings at Slavutych, the Ukrainian government representatives accepted the Shelter Implementation Plan "in principle." The representatives provided the working group with a list of questions and requests for consideration in completing the plan.

The working group reconvened in Darmstadt, Germany, on April 24 to complete the final Shelter Implementation Plan. The group also is preparing responses to guidance provided by the U.S. Department of State for the G-7 as well as the guidance provided by the Nuclear Regulatory Administration of Ukraine.

Meetings are scheduled in Slavutych and Kyiv during the week of May 12 to review those responses and the final draft of the plan. Production and distribution of the final Shelter Implementation Plan is planned for the end of May. (Dennis Kreid, PNNL, 509-375-2170)

Progress Made on Efforts to Improve Chornobyl Shelter Safety. The neutron monitoring system being developed for use in the Chornobyl Shelter was the focus of a two-day design review at Chornobyl NPP in late April. U.S. technical specialists conducted the review in response to concerns voiced by shelter staff and scientists at the Ukrainian Academy of Sciences Interdisciplinary Scientific and Technical Center-Shelter (ISTC-Shelter). In question was the adequacy of the system to perform in the stringent environment of the shelter. Representatives from the ISTC-Shelter, the Chornobyl Shelter, and Russia's Kurchatov Institute and the Institute of Physics and Power Engineering participated in the review. The review resulted in consensus support for the adequacy of the system to assess the reactivity status of fuel and fuel-containing masses within the shelter. ISTC-Shelter researchers presented data indicating that detector placement could influence overall effectiveness. The U.S. team will perform additional calculations in conjunction with the researchers in Ukraine to finalize detector locations.

While at Chornobyl for the design review, the Institute of Physics and Power Engineering and the Kurchatov Institute submitted proposals for Russian involvement in shelter cleanup work. U.S. representatives performed initial reviews, but more information is required to support evaluations of the proposed work. (John Schmidt, PNNL, 509-372-6377)


Contacts at Bratislava Workshop Support Methodology Development. During the week of April 21, the International Atomic Energy Agency (IAEA) and the U.S. Department of Energy (DOE) held their second jointly sponsored workshop on the harmonization of data structures and collection techniques for probabilistic risk assessments for Soviet-designed reactors.

The workshop was convened to obtain comments and suggestions for improving a generic methodology for structuring and collecting data. The methodology is intended for use in U.S.-funded efforts involving the development of reliability databases and the collection of data for plant-specific safety analyses. The participants agreed to provide comments on the methodology and support its finalization.

The Bratislava workshop was staged in cooperation with UJD, the Nuclear Regulatory Authority of Slovakia. In addition to U.S. team members and IAEA staff, attendees included representatives from Slovakia, the Czech Republic, Russia, Ukraine, Romania, Hungary, Holland, and Spain.

The workshop provided an opportunity to establish contacts between host country personnel working on U.S.-funded safety projects and personnel from other NPPs working on similar projects funded by other sources. Those contacts may help the U.S. team to include data already collected at those plants in the generic database for reliability analysis and probabilistic risk assessment being developed for Russian and Ukrainian NPPs.
