v o Code of Federal Regulations, Title 10, Part 50, Paragraph 50.55a (10 CFR 50.55a) specifies use of the ASME Eoiler and Pressure Vessel Code,Section XI for con-trolling inservice inspection (ISI) at nuclear nower plants.

Paragraph 10 CFR 1

50.55a current 37 specifies use of the 197h Edition of this code with Addenda through Summer 975 Requirements of 10 CFP 50.55a also sp *cify periodic updating of ISI programs, and permit the HRC to grant relief frca specific code requirements. Purcuant to these requirements, Jonsumers Poser mar.pany submitted a propcsed update and requests fcr relief for Big Rock Poirt iS' by letter dated December 22, 1978.

Consumers Pcwer Cc=pany has elected to change the ACTE code basis. rom that cited in our December 22, 1978 update sutaittal-

' he ASBE code version to be used is i

the 1977 Edition with Addenda through Summer 1978 (77078).

For certain ccaponents, requirements of the 197h Edition a Addenda through Summer 1975 (ThS75) supersede 77378 requirements; these substitutions are detailed in Table I-1.

Cons ume rs Pcwer Company 1130 has elected to adopt Subsecticn IWF of the Winter, 1978 Addenda t o s r e c i.^a' require ents for corpcnent s ur.to rt s ; Subsection IWF is undecstood to be a ecnoilation of other code requirenents technical _, equivalent to 77S78.

Adoption of Subsection IWF necessitates deletien of certain requirements from 77378 which are now incorporated in Subsection IWF; these deletions are tabulated in Table I-2.

Consumers Power Cc pany has cctpared the requirements of the composite code discussed above to the requirements of TLS75 including consideration of our pending relief requests.

The results of this tabulation are reported in Attachten 3 Tron this comparison, Cencumers Pcwer Company concludes that the proposed code basis is equivalent to or more restrictive than the code referenced in 10 CFR 59.55a.
