Draft Regulatory Analysis For Current Proposed Amendment Revision of 10 CFR 650.55a Codes and Standards 1.
Statement of the Problem The General Design Criteria (Appendix A of Part 50) of the NRC Regulations require that structures,
- systems, and components of light-water-reactors be designed, fabricated, erected, constructed, tested and inspected to quality standards commensurate with the importance of the safety function performed.
Without a set of specific rules to implement these quality standards, it would be necessary for each applicant / licensee to develop its own program for submittal to the NRC.
Each program would have to be reviewed by the staff on a case-by-case basis. This would in-b crease significantly the licensing review time and would make inspections '
by the staff more difficult because of the nonstandard nature of each program.
To provide a consistent set of rules, which the industry has participated in developing, 650.55a mandates use of Section III of the American Society of Mechanical Engineers Boiler and Pressure Vessel Code (ASME Code) for construction of Class 1, 2, 3 components, and Section XI of the ASME Code for inservice inspection of those components.
Section III and Section XI are implemented by applicants / licensees of all light-water-cooled reactors.
The NRC first endorsed the ASME Code by reference in 10 CFR 550.55a in 1971.
The ASME publishes a new edition of the Code every three years and new addenda every 6 months.
It has been a continuing policy of the Comission to update this section of the regulations to keep the references current.
In those cases where an item in the ASME Code is inconsistent with NRC criteria, an exception may be taken to endorsing that portion of the Code, or supplementary criteria may be incorporated to make the item consistent with staff requirements.
Section 50.55a last endorsed the 1980 Edition and addenda through the Sumer 1982 Addenda.
Since then, the Winter 1982 Addenda, Sumer 1983 Addenda, Winter 1983 Addenda, Sumer 1984 Addenda, and 1983 Edition have been published by the ASME.
The purpose of this proposed rule is to incorporate the new edition and addenda into the regulations.
The ASME Code is developed by the consensus process, which ensures that the various industry sectors (e.g., utility, NSSS suppliers, regula-tory) are represented on the standards writing comittees and that their viewpoints are considered in the standards writing process.
Endorsement of the ASME Code by the NRC provides a method of incorporating rules into the regulatory process that are acceptable to the NRC and have received industry participation in their development.
If the NRC did not take action to endorse the ASME Code, the NRC position on the methods for construction and inservice inspection would have to be established on a case-by-case basis.
If the NRC did not take action to update the ASME Code references, improved methods for construction and inservice inspection might not be implemented.

Objectives The proposed rule would:
Incorporate by reference into $50.55a of the NRC's regulations o
the Winter 1982 Addenda. Sumer 1983 Addenda. Winter 1983 Addenda, Sumer 1984 Addenda, and 1983 Edition of Section III, Division 1, and the Winter 1982 Addenda, Sumer 1983 Addenda, and 1983 Edition of Section XI, division 1, of the ASME Code, Incorporate revisions to corref t certain existing footnote and o
paragraph references; to simplify the language of the rule; and to delete two obsolete provisicus.
3.
Alternatives b
An alternative to incorporating 'oy reference into NRC's regulations 3 the latest requirements of Section III, Division 1, and Section XI, Division 1, and making certain editorial revisions would be to take no action.
This would mean that the NRC position on the methods for construction and inservice inspection contained in the latest edition and addenda of the ASME Code would have _to be provided on a case-by-case basis; certain incorrect footnote and paragraph references would remain in the present rule; and obsolete provisions would remain to clutter the rule.
A second alternative to incorporating by reference the latest requirements of Section III, Division 1, and Section XI, Division 1, is to incorporate the entire text of these sections of the ASME Code into the NRC regulations.
Because of the volume of these sections, this approach is not practicable.
4.
Consequences Incorporating by reference the latest edition and addenda of the ASME Code will establish the NRC staff position on these Code rules on a generic basis for applicants / licensees thereby minimizing the need for case-by-case evaluations and reducing the time and effort. required for submittal preparations and license reviews.
The cost / benefit of ASME Code revisions is balanced by the manner in which these revisions are achieved through the American National Standards Institute (ANSI) consensus process.
The ANSI consensus process ensures that participation in ASME Code development is open to all persons and organizations that might reasonably be expected to be directly and materially affected by the activity, and ensures that such persons and organizations shall have the opportunity for fair and equitable participation without dominance by any single interest.
Consensus is established when substantial agreement has been achieved by the interests involved. Consensus requires that all views and objectives be considered, and that a concerted effort be made toward resolution. ASME Code proposed revisions are published for public comment in the ASME Mechanical Engineering and ANSI Reporter publications prior to being submitted for final ASME and ANSI approval. Adverse public coments are referred to the appropriate technical comittee for resolution.
2
The consensus process ensures a proper balance between utility, regulatory and other interests concerned with revisions to the ASME Code, and ensures that the cost of any Code revision is consistent with its benefit.
Implementation of the new ASME Code rules requires certain additional information collection requirements.
The Supporting Statement for Information Collection Requirements in 10 CFR 550.55a is provided in Appendix A.
The 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 in the Small Business Size Standards set out in regula-tions issued by the Small Business Administration at 13 CFR Part 121.
Since these companies are dominant in their service areas, this proposed.
k rule does not fall in the province of this Act.
The proposed rule willi have no significant effect on a substantial number of small companies.
5.
Decision Rationale From the above analysis it is concluded that the proposed revision to incorporate the latest edition and addenda of the ASME Code will save applicants / licensees and the NRC staff both time and effort by providing uniform detailed criteria against which the staff can review any single submission. No significant additional cost to the applicants / licensees is expected as a result of NRC endorsement of the new ASME Code edition and addenda.
6.
Implementation No implementation problems are anticipated. The framework for imple-mentation is already established in both the industry and the NRC.

Appendix A Supporting Statement for Infonnation Collection Requirements in 10 CFR 650.55a 1.
Justification I
a.
Need for the Infonnation Collection NRC Regulations in 10 CFR 550.55a incorporate by reference Section III, Division 1, and Section XI, Division 1, of the American Society of Mechanical Engineers Boiler and Pressure Vessel Code (ASME Code). These sections of the ASME Code set forth the requirements to which nuclear power plant components are designed, constructed, tested and inspected.
Inherent in these requirements are certain recordkeeping functions.
Incorporation of the Winter 1982 Addenda, Sumer 1983 Addenda, Winter 1983 Addenda, Summer 1984 Addenda, and 1983 Edition for Section III, Division 1, of the ASME Code would add the following recordkeeping requirements.

Section III o
Winter 1982 Addenda NB-2125, Fabricated Hubbed Flanges - New provision l
for surface examination requires documentation of examination results.
+
o Summer 1983 Addenda No additional recordkeeping o
Winter 1983 Addenda NCA-3650, Design Documents for A>purtenances -
l Requires Design Document for eac1 appurtenance that is to be attached to a component unless it is already included in the component Design Documents.
i o
Sumer 1984 Addenda NB/NC-7240, Review of (Overpressure Protection) Report After Installation - Addendum to report required to document any modification of the installation from that used for preparation of the Overpressure Pro-tection Report.

T I
The Winter 1982 Addenda of the ASME Code references ANSI /ASME NQA-1-1979,
" Quality Assurance Program Requirements for Nuclear Power Plants."
NQA-1-1979 is based upon the contents of ANSI /ASME N45.2-1979, " Quality Assurance Program Requirements for Nuclear Facilities" and seven daughter standards. These standards are referenced in Regulatory Guides 1.28, 1.58, 1.64, 1.74, 1.88, 1.123, 1.144, and 1.146 as providing methods acceptable for implementing certain NRC quality assurance program requirements. NQA-1-1979 incorporates no recordkeeping beyond that originally required by the N45 standards upon which it is based. There is, therefore, no additional recordkeeping burden associated with the endorsement of NQA-1-1979.
b.
Practical Utility of the Information Collection These records are used by the licensees, National Board j
inspectors, insurance companies, and the NRC in the review of a variety of activities, many of which affect safety. The records are generally historical in nature and provide data on which future activities can be based. NRC Inspection and Enforcement personnel can spot check the records required by the ASME Code to determine, for example, if proper inservice examination test l
methods were utilized.
c.
Duplication With Other Collections of Information ASME requirements are incorporated to avoid the need for writing equivalent NRC requirements. The final rule will not duplicate the information collection requirements contained in any other generic regulatory requirement.
i d.
Consultations Outside the NRC i
No consultations.
i 2
The 1983 Edition of Section XI is equivalent to the 1980 Edition, as modified by the Winter 1980 Addenda, Winter 1981 Addenda, and the Winter 1982 Addenda.
A-2 i
e.
Other Supporting Information NRC applicants and licensees have been complying with the infomation collection requirements of the ASME Code since 1971.
No problems with these information collection requirements have been identified to the NRC by the applicants or licensees.
2.
Description of the Infomation Collection l
a.
Number and Type of Respondents In general, the information collection requirements incurred by i
650.55a through endorsement of the Code apply to the owners of the 34 nuclear power plants under construction and to the owners of the 93 nuclear power plants in operation. The actual number of plants that would implement the edition and addenda addressed by the proposed revision, and thereby be affected by their s
k infomation collection requirements, is dependent on a variety of factors. These factors include whether the application is for Section III or Section XI, the class and type of components involved, the dates of the construction permit and construction permit application, the schedule of the inservice inspection program, and whether the plant voluntarily elects to implement updated editions and addenda of the ASME Code.
b.
Reasonableness of the Schedule for Collecting Infomation The information is generally not collected, but is retained by the licensee to be made available to the NRC in the event of an i
NRC inspection or audit.
c.
Method of Collecting the Information See Item 2(b).
d.
Adequacy of the Description of the Infomation I
The ASME Code provides listings of information required and i
(
specific foms to assist, where necessary, in documenting j
required infomation.
e.
Record Retention Period The retention period for information is in accordance with a schedule provided in Table NCA-4134.17-1 of the ASME Code. The retention periods for information keeping requirements specified j
in Item 1.a above are:
A-3
Retention Period (3)
Infomation Design document for appurtenances Lifetime Overpressure protection report Lifetime Reports for repair and replacement Lifetime Final nondestructive examination report Lifetime Lifetime retention of the above records is necessary to ensure adequate historical infomation on the design and examination of components and systems to provide a basis for evaluating degra-dation of these components and systems at any time during their service lifetime.
i 3.
Estimate of Burden i
a.
Estimated Hours The infomation collection requirements inherent in incorporating y
by reference the latest edition and addenda of Section III,
~
Division 1, and Section XI, Division 1, of the ASME Code are identified in Item 1.a above. These requirements may be categorized in tems of Section III requirements that document component / system design and the results of construction examinations, and Section XI requirements that document repairs and replacements.
The additional Section III requirements incur a one-time burden on plants under construction. The information collection requirements associated with the proposed edition and addenda are generation of the design documents for appurtenances and the overpressure protection report. Section 50.55a specifies that the Code Edition, Addenda, and optional Code Cases to be applied to reactor coolant pressure boundary, and Quality Group B and Quality Group C components must be detemined by the provisions of paragraph NCA-1140 of Subsection NCA of Section III of the ASME Code. NCA-1140 specifies that the owner (or his designee) shall establish the ASME Code edition and addenda to be included in the Design Specifications, but that in no case shall the Code edition and addenda dates established in the Design Specifications be earlier than three years prior to the date that the nuclear power plant construction permit is docketed. NCA-1140 further states that later ASME Code editions and addenda may be used by mutual consent of the Owner (or his designee) and Certificate Holder. The earliest Section III addenda being addressed in the proposed rule is the Winter 1982 Addenda. Since the last plant to be docketed that is still under construction was docketed in October 1974 (Palo Verde Units 1, 2, 3), there is no plant under construction for which implementation of the Section III edition and addenda specified in the proposed rule is a requirement. Plants may implement these improved rules on a voluntary basis, but unless they make that choice, there is no additior.al paperwork burden associated with incorporating the proposed Section III edition and addenda.
3Service lifetime of the component or system.
A-4
- I__,
The additional Section XI requirements incur a burden associated with the documentation of component repairs and replacements.
To facilitate this documentation Section XI provides Form NIS-2, " Owners' Report for Repairs or Replacements."
Information required by this fom relates to identifying the owner and facility; identifying the components repaired or replaced and replacement components; identifying the type of work, the repair organization and by whom the work was perfomed; and identifying the type of tests conducted. A l
portion of this infomation, such as that to identify the owner, facility and components is already required by Fom NIS-1, "0wners' Data Report for Inservice Inspections," (Form NIS-1 was part of an addenda previously incorporated by reference into 550.55a). Most of the remaining information required by Form NIS-2 can be obtained from the previously prepared component work / repair order.
It is estimated that the time required to complete the required documentation on Form NIS-2 is ten hours. y Nuclear power plants are required to update their inservice inspection programs by incorporating into their initial 120-month inspection interval requirements of the latest edition and addenda of Section XI, Division 1, that have been incorporated by reference into 650.55a as of 12 months prior to the date of issuance of the operating license; and by incorporating into successive 120-month inspection intervals requirements of the latest edition and addenda of Section XI that have been incorporated by reference as of 12 months prior to the start of a 120-month inspection interval. On this basis, many plants will at one time be required to implement the Section XI, Division 1, edition and addenda specified in the proposed rule. The number of plants that will be implementing the specified edition and addenda will grow gradually as each plant updates its inservice inspection program at the 10-year interval. Therefore, conservatively, the total number of plants that may ultimately be required to implement the specified edition and addenda is 127 (i.e., 93 operating plants and 34 plantsunderconstruction).
Inservice inspections are typically performed at the time of refueling (i.e., approximately every 18 months). The need to complete an NIS-2 form would occur as a result of a repair required by the results of an inservice inspection, or as a result of an unanticipated repair between refuelings.
It is estimated that 2 NIS-2 foms are completed for repairs resulting from the inspection and 2 for repairs required during operation.
Assuming applicability to 127 plants, and the completion of 4 NIS-2 foms by each plant every 18 months, with ten hours required to collect information and complete each form, it is estimated that the total time required by all utilities to complete the NIS-2 form is approximately 3400 hours0.0394 days <br />0.944 hours <br />0.00562 weeks <br />0.00129 months <br /> / year (i.e.,
4 forms x 127 plants = 508 foms per 18 months, 508 forms x 2 =
1016 forms per 3 years,1016 forms / 3 = 339 forms per year.
I 339 forms x 10 hours1.157407e-4 days <br />0.00278 hours <br />1.653439e-5 weeks <br />3.805e-6 months <br /> per form = 3390 hours0.0392 days <br />0.942 hours <br />0.00561 weeks <br />0.00129 months <br /> per year). The time required to maintain these repair and replacement records for A-5
i f
e the period noted in Item 2.e is estimated to be 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> / year for each plant. Thus, the total time required by all utilities to complete and maintain the NIS-2 form is approximately 3517 hours0.0407 days <br />0.977 hours <br />0.00582 weeks <br />0.00134 months <br /> / year.
b.
Estimated Cost Required to Respond to the Collection Based upon the hours specified in Item 3.a. it is estimated that the cost of responding to the information collection required by the Section III, Division 1, and Section XI Division'1, edition and addenda specified in the proposed amendmeht to 650.55a is a total of $211.020/ year (3517 hrs x $60/hr) for 127 plants.
c.
Source of Burden Data and Method for Estimating Burden Estimates of the number of NIS-2 forms that are completed during a year and the time required to collect the necessary
,T im information and to complete the forms, were obtained from utility staff inservice inspection specialists and NRC staff in the Office of Inspection and Enforcement (regional and headquarters) engaged in inservice inspection activities.
d.
Reasonableness of Burden Estimate The estimate of the burden is considered reasonable because of the reliable source of the burden data.
4.
Estimate of Cost to the Federal Government NRC inspection personnel who audit plant quality assurance records would include in their audit verification of the proper implementation of the NIS-2 form. The time associated with NRC inspectors verifying use of the NIS-2 form would be extremely small when the activity is performed as part of a normal quality assurance audit.
