This meeting related to apparent violations identified in NRC Inspection Report 50-285/96-17. These apparent violations included maintenance, configuration control, and operability concerns with the postaccident sampling system. During the meeting, representatives of the Omaha Public Power District presented information related to the identification, causes, and corrective actions for the apparent violations and presented their analysis related to the ' operability of the system. In accordance with Section 2.790 of the NRC's " Rules of Practice," Part 2, Title 10, Code of Federal Regulations, a copy of this letter will t,e placed in the NRC's Public Document Room. Should you have any questions concerning this matter, we will be pleased to discuss them with you. , Sincerely, " Ir J. E. yer, Director Division of Reactor Projects Enclosures: 1.

. f une I,190 System Encincering Depaniment POST ACCIDENT SAMPLING SYSTEM ACTION PLAN I. PROBLEM STATEMENT These are sescral issues associated with the Post Accident Sampling System (PASS) which bring into question the ability of the PASS to operate rejiab' under all conditions, per the requirements of NUREG-0737 and OPPD's associated commitments. . II. GOALS A. Verify the ability of PASS equipment to operate reliably in both the NORMAL and ACCIDENT modes. n. Verify the design basis and operational constraints of the PASS. C. Verify adherence to commitments associated with the PASS. D. Develop a comprehensive program document for the PASS which: 1. Ensures that the PASS will operate reliably, under all conditions when called upon to do so. 2. linsures that equipment problems which arise will be given the appropriate priority commensurate with the level of importance to maintaining the system in an operable status. 3. Capti res and maintains system operational constraints and references to the system design basis. 4. Captures, and verifies adherence to, all OPPD commitments associated with the PASS. 5. Delineates qualification and proficiency requirements for personnel operating the PASS. 6. Meets the requirements of Tccimical Specification 5.15. , PASSPLAN.CilF Rev. 6, 3/22/94 Page 1 of 5 + -- - - -- - - - - - . . - - .
