to assess plant and environs conditions during and following an accident. 2. Information to be Reviewed The information to be reviewed for accident monitoring instrumentation is described in Standard Review Plan (SRP) Section 7.5. 3. Acceptance Criteria The design and qualification criteria identified in Regulatory Guide 1.97 should be supplemented by the considerations outlined below: Environmental Qualification 10 CFR 50.49(b)(3), “Certain post-accident monitoring equipment,” has been interpreted by the staff as follows: For plants using Revisions 2 or 3 of Regulatory Guide 1.97, accident monitoring equipment that falls within the scope of Category 1 or 2 equipment should be environmentally qualified as required by 10 CFR 50.49, or the applicant/licensee should provide an acceptable alternative for complying with 10 CFR 50.49(b)(3). For plants using Revision 4 of Regulatory Guide 1.97, accident monitoring equipment identified as Type A, B, or C in accordance with that guide should be environmentally qualified as required by 10 CFR 50.49. Type D variables should be environmentally qualified for the particular accident's postulated environment at the installed location in accordance with the plant's licensing basis. Licensees converting to Revision 4 or performing modifications based on Revision 4 may reference previously accepted alternatives as their basis for deviations from the environmental qualification criteria in Revision 4. Seismic Qualification For plants using Revisions 2, 3, or 4 of Regulatory Guide 1.97, if a reactor licensing basis does not include a commitment to Regulatory Guide 1.100, “Seismic Qualification of Electric Equipment for Nuclear Power Plants,” and credit is taken for original equipment in meeting the guidelines identified in Regulatory Guide 1.97, installation of the original equipment in conformance with the licensing basis for seismic qualification is acceptable, provided the other BTP 7-10-4 Revision 5 - March 2007 guidelines
