ENCLOSURE 3 The maximum allowable releases of radioactivity from nuclear poi;er plants as ex-pressed in the regulations have uncergone two somewnat major revisions since the first commercially operating f acility, Shippingport in 19b7. The initial effluent limitations plus the revisions can be summarized as follows:
- 1) Prior to 1971 all operating reactor licenses tnat were issuea naa maximum effluent limitations which corresponded to off-site concentrations equal to the values in 10 CFR Part 20, Appencix B, Taule 11. In general, tnese con- '
centrations if continued over a year period represent potential ooses via the innalation and drinking water patnways of 500 mrem to tne whole bocy or 1500 mrem to the tnyroid, cepending on tne racionuclides in question.
'2) With the issuance of staff proposed "As Low As Practicaole" (ALAF) cri-teria (Feaeral Register, Vol. 36, No.11, Wecnesday, June 9,1971) the then AEC oegan imple.nenting more restrictive raaioactive effluent limits J
with the issuance cf new licenses. Tnese proposeo ALAP criteria limitea the releases to a small percent of the 10 CFR Part 20 limits, i.e. , a small fraction of the annual 600 mrem whole Docy cose. The actual cetails of these proposeo criteria and the rulemaKing proceecing that followea are too lengthy to discuss here.

- 3) On May 6,1975, the riuclear Regulatory Commission issueu its cecision in the rulemaking proceeding concerning tne criteria "as low as practicaole" for racioactive effluents (40 FR 6439). The Commission nas furtner amenceu the regulation to incorporate tne tenn "as low as is reasonaoly acnlevaole" 1
(ALARA) not to reflect a change in tne criteria, out rather to .use a lan-guage that more clearly cescribes its intention. The 14RC 1s currently in tne midst of imposing Technical Specifications ana Limiting Concition of Opera- !
l tion on all operating LWRs that implement this ALARA naling. The major uit- l 1
ferences oetween tne staff proposed rule in 1971 anc the t1nal rule tnat was l issueo are 1) effluent limits' are on a per reactor casis ano not per site and 2) tne absolute curie limitations wnicn were initially incluceu to limit population cases have Deen replaced by a cost-cenet1t type approacn wnicn J l

The actual racioactive effluent limits from nuclear power plants are not expressed
- as curie quantities out as cases to an inciv1cual. These cases are calculational limits whicn cepena on the racionuclices present and the envi ronmental patnway s.
A copy of tne final rule (Appencix I to 10 CFR Part su) is enclosea for your use in perceiving tne current criteria for releases of racioactivity from nuclear pcwer plants. The staff is presently implementing tne "As Low As Is Reasonaoly Acnievable" type technical specification limits on radioactive effluents on all nuclear power plants. Presently all operating plants have tecnn1 cal specifications caseo upon the staff proposeo ALAP except the follcwing plants: naccam Necx, San Onofre, Yankee Rcwe, Dresden 1, :sig Rock Point, Lacrosse, anu Uyster Creex. For tnese facilities, tne effluent limitations are caseo on tne pre-b71 criterla (i.e., concentrations of-10 CFR Part cu).
