sidered a full implementation of the AST. With this approval, the previous accident source term in the <facility> design basis is superseded by the AST proposed by <licensee>. The previous offsite and control room accident dose criteria expressed in terms of whole body, thyroid, and skin doses are superseded by the TEDE criteria of 10 CFR 50.67 or small fractions thereof, as defined in RG-1.183. All future radiological analyses performed to demonstrate compliance with regulatory requirements shall address all characteristics of the AST and the TEDE criteria as described in the <facility> design basis. 7. For a selective implementation of an AST, text similar to the following is to be included in the conclusion: This licensing action is considered a selective implementation of the AST. With this approval, the selected characteristics of the AST and the TEDE criteria, if applicable, become the design basis for the <explain the boundaries of the approved implementation>4. This approval is limited to this specific implementation. Subsequent modifications based on the selected characteristics incorporated into the design basis by this action may be possible under the provisions of 10 CFR 50.59. However, use of other characteristics of an AST or use of TEDE criteria which are not part of the approved design basis, and changes to previously approved AST characteristics, requires prior staff approval under 10 CFR 50.67. The selected characteristics of the AST and the TEDE criteria may not be extended to other aspects of the plant 15.0.1-16 Rev. 0 -- July 2000 design or operation without prior NRC review under 10 CFR 50.67. All future radiological analyses performed to demonstrate compliance with regulatory requirements shall address the selected characteristics of the AST and the TEDE criteria as described in the <facility> design basis. V. IMPLEMENTATION The preceding material in this SRP section is intended to provide guidance to operating power reactor licensees applying
