ENCLOSURE 1 Guidance to Holders of Per=1ts to Construct or Licenses to Operate Light-Water-cooled Reactors for Which Application was Filed Prior to January 2, 1971 to Meet the Requirements of Appendix I to 10 C7R Part 50 1.
Licensees should provide an evaluation showing their facility's capability to =cet the require =ents set forth in Section II of Appendix I to 10 CFR Part 50.
2.
Radioactive Source Ter=s used in the evaluation should be consistent with the paraceters and =cthodology set forth in Draft Regulatory Guides 1.3B or 1.CC (as appropriate).
Note: For BWRs gaseous releases from the containment building and auxiliary building should be combined to form reactor building release for pre-BWR/6 Mark III Contain=ent designs.
3.
M2teorolo2v/E.drolegy infor=ation used in the calculation of doses should be consistent with Draft Regulatory Guides 1.DD and 1.EE.
.4 Dese Calculations should be consistent with Draft Regulatery Guide 1505 162 1.ix.
5.
Effluent Release Data from previous reactor operation should be provided, if available, for use in evaluating the source tern calculations.
Such data should include at least one full year of effluent release data tabulated by effluent release point, conth,
= ode of operation (e.g., full power operation, refueling shutdown),
excluding the first year of reactor operatien.

The above evaluations should be accenpanied by the infor:stien requested in Enclosure 2 Ex.eptions from the infor=ation requested will be considered on a case-by-case basis.
7.
The staff is preparing standard Technical Specifications and will issue further guidance to licensees regarding changes to Technical Specifications to i=plement the Appendix I objectives.
Proposed revisions to Technical Specifications by licensees based on the limiting conditions for operation set forth in Section IV of Appendix I should~ be withheld pending further guidance from the staf f.
