Federal Register Notice NUCLEAR REGULATORY COMMISSION 10 CFR Part 50 Codes and Standards for Nuclear Power Plants AGENCY: Nuclear Regulatory Comission.
ACTION: Final rule.
SUMMARY
The Comission is amending its regulations to incorporate by reference the Winter 1982 Addenda, Sumer 1983 Addenda, Winter 1983 Addenda, Sumer 1984 Addenda and 1983 Edition of Section III, Division 1, of the American Society of Mechanical Engineers Boiler and Pressure Vessel Code (ASME Code) , and the Winter 1982 Addenda, Sumer 1983 Addenda, a The sections of 1983 Edition of Section XI. Division 1, of the ASME Code.
the ASME Code being incorporated provide rules for the construction of light-water-cooled nuclear power plant components and specify requireme for inservice inspection of those corr.ponents. Adoption of these amendments would permit the use of improved methods for construction and inservice inspection of nuclear power plants.
I EFFECTIVE DATE:
(Insert date 30 days after publication in the FR).
incorporation by reference of certain publications listed in the The regulations is approved by the Director of the Federal Register as of (Insert date 30 days after publication in the FR).

SUPPLEMENTARY INFORMATION: On May 17, 1985, the Nuclear Regulatory Comission published in the Federal Register (50 FR 20574) a proposed amendment to its regulation, 10 CFR Part 50, " Domestic Licensing of
- Production and Utilization Facilities," to update ' existing references .
i to specific editions and addenda of the American Society of Mechanical Engineers Boiler and Pressure Vessel Code (ASME Code); to make editorial corrections to the existing rule; to simplify the language of the rule; and to delete two obsolete provisions.
This amendment revises $50.55a to incorporate by reference all editions P through the 1983 Edition and all addenda through the Sumer 1984 Addenda that modify Division 1 rules of Section III, " Rules for the Construction of Nuclear Plant Components " and all editions through the 1983 Edition .
and all addenda through the Sumer 1983 Addenda that modify Division 1 rules of Section XI, " Rules for the Inservice Inspection of Nuclear Power Plant Components," of the ASME Code. The Sumer 1983 Addenda for Section XI does not include technical requirements related to Division 1, but is
^
included in the reference to prevent the confusion that might occur with a lack of continuity in the addenda references.
f y Editorial revisions are included in this amendment to correct certain existing footnote and paragraph references that are inconsistent with the last amendment (49 FR 9711) to this rule and to simplify the language.
These editorial revisions are contained entirely in 650.55a(g).

For facilities whose operating licenses were issued prior to March 1,1976, this rule provided the effective date for implementing the inservice inspection requirements and for defining the effective edition and addenda of the Code for the start of the next one-third of a 120-month inspection interval after September 1,1976. Since this one-third of an inspection 4 interval has already been completed for all applicable facilities.
4 550.55a(g)(4)(iii) which addresses the implementation of that inspection
' is unnecessary and is deleted by this amendment.
Power reactors for which a notice of hearing on an application for a provi-sional construction pemit or a construction permit had been published on or before December 31, 1970, were pemitted to use the rules for construction required for power reactors that had received their construction pemits prior to January 1, 1971. This amendment deletes 150.55a(1) which covers this provision because it is no longer necessary. Section 50.55a(c)(4) provides that for these and other facilities that received a construction pemit prior to May 14, 1984, the applicable Code Edition and Addenda for a component of the reactor coolant pressure boundary continue to be that Code Edition and Addenda that were required by Connission regulations for the component at the tim of issuance of the construction pemit.
i Interested persons were invited to submit written connents for considera-tion in connection with the proposed amendment and the draft regulatory analysis by July 16, 1985. No adverse connents or significant questions were received in response to the notice of proposed rulemaking.

REGULATORY FLEXIBILITY CERTIFICATION As required by the Regulatory Flexibility Act of 1980, 5 U.S.C.
l 605(b), the Comission hereby certifies that this rule does not have a significant economic impact on a substantial number of small entities.
This rule affects only the licensing and operation of nuclear power
' plants. The companies that own these plants do not fall within the scope of the definition of "small entities" set forth in the Regulatory Flexibility Act or the Small Business Size Standards set out in regula-tions issued by the Small Business Administration at 13 CFR Part 121.
