ble to the Staff for instrumentation to assess plant and environs conditions during and following an accident. 2. Information to be Reviewed The information to be reviewed for post-accident monitoring systems is in the SRP Section 7.5. 3. Acceptance Criteria The design and qualification criteria identified in Reg. Guide 1.97 should be supplemented by the considerations outlined below: Environmental Qualification of Category 1 and 2 Instrumentation 10 CFR 50.49(b)(3) has been interpreted by the Staff to require that all post-accident monitoring equipment that falls within the scope of Category 1 or 2 equipment (as defined in Revision 2 of Reg. Guide 1.97) 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). 10 CFR 50.49 provides an acceptable basis for environmental qualification of Category 1 and Category 2 instrumentation as defined in Reg. Guide 1.97 Revision 2 or Revision 3. In addition, the use of Reg. Guide 1.97 Revision 3 in lieu of Revision 2 in itself does not exempt the applicant/licensee from addressing environmental qualification of Category 1 and 2 equipment. Seismic Qualification of Category 1 Instrumentation If a reactor licensing basis does not include commitment to Reg. 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 Reg. Guide 1.97, then installation of the original equipment in conformance with the licensing basis for seismic qualification is acceptable, provided the other guidelines identified in Reg. Guide 1.97 and this BTP are satisfied. However, for all reactors, new instrumentation that is installed for the purpose of satisfying Reg. Guide 1.97, or new instrumentation that is installed to replace original equipment for which credit was taken in satisfying Reg. Guide 1.97, should satisfy the seismic qualification
