These exemptions meet the staff recommendations from SECY 93-087 which were approved by the Commission in a Staff Requirements Memorandum (References 19 and 20).61 7. EMCB determines that a post-accident sampling system administrative program has been established, implemented and will be maintained to ensure the plant has the capability to DRAFT Rev. 3 - April 1996 9.3.2-14 obtain and analyze reactor coolant samples, containment atmosphere samples, radioactive iodides and particulates in plant gaseous effluents under accident conditions (References 21 and 22). The administrative program should include: a) training of personnel b) procedures for sampling
