and guidance and in general describe a basis acceptable to the staff that may be used to meet the requirements of 10 CFR §50.48 , GDC 3 and 5: 29 a. Branch Technical Position (BTP) CMEBSPLB 9.5-1 as it relates to the design 30 provisions given to implement the fire protection program. b. Regulatory Guide 1.78 as it relates to habitable areas such as the control room and to the use of specific fire extinguishing agents. c. Regulatory Guide 1.101, as it relates to fire protection emergency planning. 9.5.1-5 DRAFT Rev. 4 - April 1996 d. For new applications, the standard design must comply with 10 CFR Part 50, Appendix R, Section III.G.1.a and ensure that safe shutdown can be achieved assuming all equipment in any one fire area will be rendered inoperable by fire and that re-entry into the fire area for repairs and operator actions is not possible. The design must ensure that smoke, hot gasses, or fire suppressant, will not migrate into other fire areas to the extent that could adversely affect safe shutdown capabilities including operator actions. The control room is excluded because an alternative shutdown capability is provided which is physically and electrically independent of the control room. In the reactor containment, redundant shutdown systems must be provided with fire protection to ensure, to the extent practical, that one shutdown division be free of fire damage. Because of unique design layout, other areas may be accepted on an individual basis.31 e. For new applications, the fire protection program should address protection of safe shutdown functions, specifically decay heat removal, during shutdown and refueling operations. NUREG-1449 (Reference 8) provides the NRC's evaluation, findings and other relevant information regarding fire protection in these modes of operation.32 Technical Rationale:33 The technical rationale for application of the above acceptance criteria to the fire protection program is discussed in the following paragraphs. 1.
