- Debris Drywell Transport Study
- of NRC Contract NRC-04-95-047 j
- Technical Assistance in Resolving Generic Safety issues
- j (FIN No. W6325)
BACKGROUND in December 1995, .:.e Office of Nuclear Reactor Regulation (NRR) requested that the Office of Nuclear Regulatory Research (RES) develop analytical models or approaches for debris i transport in the drywell that are suitable for evaluating licensee solutions to the BWR suction l
strainer debris blockage issue. The results of the Debri?Orywell Transport Study (DDTS) are
! intended to provide a reasonable basis for making an informed engineering judgement on the magnitude of debris transport from the drywell to the wetwell. Because of the resources available to conduct this study, the DDTS was not intended to produce quantitative results nor develop accurate predictive analytical models. RES contracted with Science and Engineering Associates, Inc. (SEA) in late July 1996 to pedorm the DDTS.
In May__1997 SEA completed the study, but the completed study placed less reliance on severe L accident and computational fluid dynamic codes and more reliance on experiments and simpler -
analytical methods that will integrate the experiments and analytical work than the original study (i.e., plan). An unanticipated result of that technical, directional shift was a greater need for
- documentation. The original statement of work only specified one technical report, but at least three are needed to adequately document the study. -
QRJECT*NES Subtask 1-Prepare NUREG/CR reports to document the results, methodology, experimental basis and engineering basis of the DDTS.
Subtask 2 Participate in the Phenomenon identification Ranking Table (PIRT) Panel meeting scheduled to take place in Albuquerque, NM during the 3rd quarter of the calender year 1997.
