Federal Register Notice NUCLEAR REGULATORY COMISSION
~
10 CFR Part 50 Codes and Standards for Nuclear Power Plants -
AGENCY: Nuclear Regulatory Comission.
ACTION: Proposed Rule.
SUPMARY: The Commission proposes to amend its regulations to incorporate by reference the Winter 1982 Addenda, Sumer T983 Addenda, Wint r 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, and 1983 Edition of Section XI, Division 1 of the ASME Code. The sections of the ASME Code being incorporated provide rules for the construction of light-water-cooled nuclear power plant components and specify requirements for inservice inspection of those components. Adoption of these amendments would permit the use of improved methods for construction and inservice inspection of nuclear power plants.

FOR FURTHER INFORMATION CONTACT: Mr. G. C. Millman, Division of Engineering Technology, Office of Nuclear Regulatory Research, U.S.
Nuclear Regulatory Conusnission, Washington, D.C. 20555, Telephone-(301)443-1860.
SUPPLEMENTARY INFORMATION: On February 7, 1983, the Nuclear Regulatory Commission published in the Federal Register (48 FR 5532) amendments to its regulation, 10 CFR Part 50, " Domestic Licensing of Production and Utilization Facilities," which incorporated by reference new addenda to i the American Society of Mechanical Engineers Boiler and Pressure Vessel i
Code (ASME Code). The amendment revised $50.55a to incorporate by reference the Winter 1981 Addenda to Division 1 rules of Section III,
" Rules for. the Construction of Nuclear Power Plant Components," and l
Division 1 rules of Section XI, " Rules for Inservice Inspection of Nuclear
[
i Power Plant Components " of the ASME Code. On November 4,1983, the Comission published in the Federal Register (48 FR 50878) an amendment to 150.55a to incorporate by reference the Sumer 1982 Addenda to Section III, Division 1, of the ASME Code. The ASME did not publish a Sununer 1982
! Addenda to Section XI. On March 15, 1984, the Comission published in the Federal Register (49 FR 9711) an amendment to 650.55a to, among other l

things, incorporate by reference those subsections of Section III which I
apply to the construction of Class 2 and Class 3 components. i l
1 Since publication of the last ASME Code addenda incorporated by-reference in 650.55a, the Winter 1982 Addenda, Sumer 1983 Addenda, Winter 1983 i Addenda, Sumer 1984 Addenda, and 1983 Edition, to the ASME Code have been issued. The 1983 Edition is equivalent to the 1980 Edition, as modified by the Summer 1980 Addenda, Winter 1980 Addenda, Sumer 1981 Addenda, Winter 1981 Addenda, Sumner 1982 Addenda, and Winter 1982 Addenda. The-Comission proposes to amend 550.55a to incorporate by reference all editions through the 1983 Edition and all addenda through the Summer 1984 Addenda that modify Section III, Division 1, and all editions through the
- 1983 Edition and all addenda through the Summer 1983 Addenda that modify Section XI Division 1, of the ASME Code. The Sumer 1983 Addenda for Section XI does not include any technical requirements related to Division 1, but is being included in the reference to avoid confusion that might occur with a lack of continuity in the addenda references.
4 Editorial revisions are proposed to correct certain existing footnote and paragraph references that are inconsistent with the last amendment j (49 FR 9711) to this rule and to simplify the language. These editorial
! revisionsarecontainedentirelyin550.55a(g).

For facilities whose operating licenses were issued prior to March 1, 1976, this rule provides the effective date for implementing the inservice inspec-tion requirements and for defining the effective edition and addenda of the Codeforthestartofthenextone-thirdofa120-monthinspecjion-interval after September 1, 1976. Since this one-third of an inspection interval has already been completed for all applicable facilities, it is proposed that the part of the rule addressing it in 650.55a(g)(4)(iii) be deleted.
1 Power reactors for which a notice of hearing on an application for a provi:
i sional construction permit or a construction permit had been published on or before December 31, 1970, were pennitted to use the rules for construction required by power reactors that had received their construction permits prior to January 1, 1971. Itisproposedthat550.55a(i)whichcoversthispro-vision be deleted because it is no longer necessary. Section50.55a(c)(4) provides that for these and other facilities that received a construction pennit 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 Comission regulations for the component at the time of issuance of the construction pemit.
4 REGULATORY ANALYSIS
- The Comission has prepared a draft regulatory analysis on this pro-posed regulation. The analysis examines the costs and benefits of the
{
I alternatives considered by the Comission. The draft analysis is available for inspection in the NRC Public Document Room,1717 H Street l

PAPERWORK REDUCTION ACT STATEMENT This proposed rule amends information collection requirements that are subject to the Paperwork Reduction Act of 1980 (44 U.S.C. 3501 et
- seq.). This rule has been submitted to the Office of Management and
) Budget for review and approval of the paperwork requirements.
i REGULATORY FLEXIBILITY CERTIFICATION In accordance with the Regulatory Flexibility Act of 1980, 5 U.S.C.
605(b), the Commission hereby certifies that this rule will not, if pro-mulgated, have a significant economic impact on a substantial number of small entities. This proposed 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 j
regulations issued by the Small Business Administration at 13 CFR Part 121.
1 5
[7590-01]
Since these companies are dominant in their service areas, this proposed rule does not fall within the purview of the Act.
