Notice of the Office of Management and Budget review of information collection.
SUMMARY
The Nuclear Regulatory Commission (NRC) has recently submitted'to the Office of Management and Budget-(OMB) for review the following proposal l
for the collection of information under the provisions of the Paperwork Reduction Act (44 U.S.C. Chapter 35).
1.
Type of submission, new, revision, or extension: Revision 2.
The title of the information collection:
10 CFR Part 50.65 - Requirements for Monitoring the Effectiveness of Maintenance at Nuclear Power Plants.

Abstract: The Commission is proposing to amend its regulations in 10 i
CFR 50.65 to change the frequency for commercial nuclear power plant i
1 licensees to evaluate the effectiveness of maintenance activities for j
safety significant plant equipment in order to minimize the likelihood of failure and events caused by the lack of effective maintenance. The annual evaluation requirement currently in 10 CFR 50.65 is being amended from annually to once per refueling cycle but not to exceed 24 months because the Commission believes that the quantity and quality of data obtained during refueling outages would be substantially greater than that available on an annual schedule and would provide a more meaningful basis for the recognition and interpretation of trends.
Copies of the submittal may be inspected or obtained for a fee from the NRC Public Document Room, 2120 L Street, (Lower Level) NW, Washington, DC 20555.

l OMB SUPPORTING STATEMENT FOR 10 CFR E 50.65,
{
" REQUIREMENTS FOR MONITORING THE EFFECTIVENESS OF i
MAINTENANCE AT NUCLEAR POWER PLANTS" (3150-0011)
Description of the Information Collection The final maintenan'ce rule, published in July of 1991 and effective July 10, 4
l 1996, requires that the licensees monitor the performance of certain j
structures, systems, and components (SSCs) within the scope of the rule against licensee-established goals, in a manner sufficient to provide l
reasonable assurance that such SSCs are capable of fulfilling their intended j
functions. Monitoring is not required where it has been demonstrated that the
(
perfomance or condition of an SSC is being effectively controlled by l
1 appropriate preventive maintenance, such that the SSC remains capable of j
l perfoming its intended function. Performance and condition monitoring j
activities and associated goals and preventive maintenance activities shall be evaluated at least annually. The objective of preventing failures through j
maintenance is to be balanced against the objective of minimizing unavailability of SSCs.
In performing monitoring and preventive maintenance activities, an assessment of the total plant equipment that is out of service should be taken into secount to determine the overall effect on perfomance of safety functions.
This proposed rulemaking modifies the requirement in section 50.65 (a)(3) by l
reducing the required frequency for evaluations of perfomance and condition i
i monitoring activities and associated goals and preventative maintenance actions from annually to once every refueling cycle not to exceed 24 months.
The NRC believes that the quantity and quality of data obtained during j
refueling outages will generally be substantially greater than that which would be available on an annual schedule because evaluations of data i
accumulated over a period of a refueling cycle, as opposed to the shorter annual period currently required by the rule, will provide a more meaningful basis for the recognition and interpretation of trends and problem areas.
i i
A.
JUSTIFICATION 1
1.
Need for the Collection of Information.
Licensees must collect j
and analyze infomation concerning the performance of SSCs within the scope of the maintenance rule in order for them to use J
infomation from past experience to predict future plant i
vulnerabilities.and plan appropriate maintenance activities aimed at eliminating or mitigating them.
)
2.
Anency Use of Infomation.. Information on performance criteria, goal setting and monitoring 'results, failure data, unavailability data, and documentation of periodic assessments required by the
-rule will be reviewed at the licensee's facilities by the NRC's inspectors in order to evaluate SSC performance and ensure that a
the SSCs are capable of fulfilling their intended function, and

l thereby maintain safe operation of the plant. Reporting of information to NRC headquarters or regional offices is not required.
3.
Reduction of Burden Throuah Information Technoloav.
The requirements in i 50.65 do not require licensees to use any particular information technology. However, the NRC encourages the use of new and effective technology that would reduce the burden for the collection and management of information.
~
i 4.
Effort to Identify Duplication.
Licensees are currently required i
to collect and document information concerning the condition and behavior of plant equipment in accordance with 10 CFR 50, Appendix 1
B (e.g., procedures, quality assurance programs, records),
5 50.36 (surveillance requirements), 5 50.48 (fire protection),
50.49 (environmental qualification), f 50.55a (in-service inspection requirements), i 50.61 (pressurized thermal shock),
5 50.62 (anticipated transient without scram), 5 50.63 (station blackout), and 10 CFR 54 if applicable (license renewal). At j
least some of this same information will be used by licensees to partially meet the requirements in 5 50.65 with respect to safety-related SSCs.
5.
Effort to Use Similar Information.
Currently required or voluntary information and documentation will be used where j
available, i.e.,10 CFR 50 sections listed under item 4 above.
j i
6.
Effort to Reduce Small Business Burden.
The rule affects only nuclear power reactor licensees. None of these licensees fall within the definition of a small business, as defined in the Comission's Size Standards (50 FR 50241; December 9,1985).
7.
Consecuences of less Frecuent Collection.
Licensees are required to assess the overall effectiveness of their maintenance efforts at least once every refueling cycle provided the interval between evaluations does not exceed 24 months. Collection of failure and unavailability information and attendant cause analyses are driven by the frequency and type of failures. NRC inspectors will be expected to judge the adequacy of each licensee's efforts by the results in terms of acceptability of failure rates and unavailability rates for plant equipment. Accordingly, the frequency of collection of data is driven by events as well as the existing maintenance schedule for each plant.
It is not possible to collect the information less frequently and yet insure the safety of the public and pir.nt operation.
8.
Circumstances Which Justifv' Variation From OMB Guidelines There are no variations from the OMB Guidelines.
9.
Consultations Outside the Acency.
The NRC staff has had several interactions in public meetings with NUMARC since the publication of the maintenance rule. At one of the meetings in the spring of 1992, NUMARC made a suggestion that the NRC consider the possibility of going to a refueling cycle outage in lieu of an annual requirerent for performance evaluations. NRC agreed to consider the matter.
10.
Confidentiality of Information.
None.
~
11.
Justification for Sensitive Ouestions.
No sensitive information is requested under this regulation.
12.
Estimated Annualized Burden to the Federal Government. The NRC already performs maintenance inspections and maintenance evaluations as a routine part of the inspection process. The proposed change to the maintenance rule is not expected to impact the burden associated with the inspection activity.
13.
Estimate of Burden. The industry burden will actually be reduced because the performance evaluations performed by power plant licensees will change from annually to once every refueling outage but not to exceed 24 months.
It is currently estimated that the time to complete a periodic assessment (including data collection) is approximately 1400 hours0.0162 days <br />0.389 hours <br />0.00231 weeks <br />5.327e-4 months <br /> per plant. The staff estimates that the reduced frequency of performing the required evaluation will result in a burden decrease of approximately 150 hours0.00174 days <br />0.0417 hours <br />2.480159e-4 weeks <br />5.7075e-5 months <br /> per plant The reduction in burden to the industry is therefore 16,500 hours0.00579 days <br />0.139 hours <br />8.267196e-4 weeks <br />1.9025e-4 months <br /> (150 hours0.00174 days <br />0.0417 hours <br />2.480159e-4 weeks <br />5.7075e-5 months <br /> X 110 plants) and a cost reduction of approximately 2 million dollars (16,500 hrs X $123.00/ hour).
- 14. Reason for chance in burden. The proposed rulemaking would reduce the frequency of licensee evaluations from annually to once every refueling outage, not to exceed 24 months.
15.
Publication for statistical use. None.
