Activity Report

for the period June 28 through July 11, 1997
Prepared by Pacific Northwest National Laboratory (PNNL), Richland, Washington


Bid Specifications Being Prepared for Chornobyl Shelter Early Biddable Projects. The team developing bid specifications for the Chornobyl Shelter early biddable projects (EBPs) met in Darmstadt, Germany, during the week of June 23. Specifications Team members include U.S. and European Commission (EC) experts plus a participant from the European Bank for Reconstruction and Development (EBRD). The team finalized a work plan, established assignments, developed templates for the EBP bid specification packages, and prepared strawman drafts of packages that served as points for focussing discussion. The team members now are working at their home sites, but in close coordination, to prepare the bid specification packages for the first-phase projects--the tasks of highest priority relative to the overall schedule. Individual members are planning to meet again as a team on July 21 through 25 in Darmstadt to review progress at that point on those first-phase tasks. The team also will begin developing the bid specification packages for the second-phase projects. The EBP specification packages are scheduled to be completed by the end of September 1997.

The Specifications Team has been asked to expand its support to the EBRD to complete the entire slate of documentation for tendering of the early biddable projects. The U.S. and EC participants have agreed to do this and have started negotiating the necessary contracts. (Dennis Kreid, PNNL, 509-375-2170)


Bulgaria: Training Methodology Seminar Held for Kozloduy Senior Managers. During the week of June 23, a seminar on the Systematic Approach to Training (SAT) methodology was conducted for senior management at Kozloduy nuclear power plant (NPP). The seminar was held to enhance plant management understanding of the SAT methodology. Seminar leaders discussed the benefits of SAT, described the roles and responsibilities of management in developing and implementing training programs, and reviewed lessons learned in implementing SAT in the United States, Russia (Balakovo NPP), and Ukraine (Khmelnytskyy NPP). The seminar was well attended by Kozloduy senior management and will enhance support of the ongoing U.S./Bulgarian cooperative project to transfer SAT methods and develop training programs at the Kozloduy plant. All translated seminar materials (viewgraphs, student workbooks, and instructor lesson plans) were provided to the Kozloduy training department for future use in training other plant personnel on the SAT methodology.

Bulgaria: Scientists Training on RELAP5 for Bulgarian VVER Plants. A fourth basic training course on the RELAP5 code began on June 26. Students in this course are eight scientists from Bulgaria--six from Kozloduy NPP and two from the Institute for Nuclear Reactors and Nuclear Energy in Sofia. Technical experts from two national laboratories are presenting the course in Idaho Falls, Idaho. The training provides lectures introducing the RELAP5 code and hands-on workshop exercises illustrating use of the code for performing thermal-hydraulic analyses of VVER reactors. To meet the specific needs of the Bulgarian students, the last week of the course will be focused on modeling Kozloduy's VVER-1000 reactors. This fourth session of the RELAP5 basic training will end on July 23. (Don Fletcher, INEEL, 208-526-7652; Ross Jensen, ANL, 208-533-7911)

Slovakia: Transfer of Reactor Confinement Analysis Codes Completed. During the week of June 23, Slovakian participants received hands-on training in the use of two computer codes, PACER and NEPTUNE, for performing confinement analyses of their Soviet-designed reactors. PACER calculates short-term confinement loads for postulated coolant system failures. NEPTUNE is a three-dimensional code for analyzing structural response. Three staff members of Argonne National Laboratory conducted the course in Trnava for representatives of the Nuclear Regulatory Authority and the Slovakian Academy of Science. The training course was the final activity in this cooperative project to transfer confinement analysis capability to Slovakia. (Nick Grossman, DOE, 301-903-3299)
