SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION SUPPORTING AME,NDMENT NO.12 TO FACILITY OPERATING LICENSE NO. R-59 IOWA STATE UNIVERSITY _
DOCKET NO. 50-116
1.0 INTRODUCTION
' By letter dated December 22,1997, as revised on February 10,1998, the Iowa State University (licensee) requested that the Definitions in the Technical Specifications (TS) be added to specify grace periods associated with surveillance and maintenance intervals.
2.0 EVALUATION in order to avoid misinterpretations of the grace periods associated with surveillance and maintenance intervals in the TS, the licensee has proposed the following definitions.
SURVEILLANCE TIME INTERVALS - The average ovr r any extended period for each surveillance time interval shall be closer to the identified surveillance time then to the maximum allowed time, (e.g, for the annualinterval the average shall be closer to 12 months than to 13 months).
Biennial -
once every 2 years (interval not to exceed 25 months)
Annual - once every 12 months (interval not to exceed 13 months)
Bi annual - once every 6 months (interval not to exceed 7 months)
Quarterly - once every 3 months (interval not to exceed 4 months)
Monthly - once every 30 days (interval not to exceed 6 weeks)
Any extension of these intervals shall be occasional and for a valid reason and shall not affect the average as defined.
.The definition provides some latitude in performing surveillance to account for periods when they couldn't be performed during the required interval, but precludes repetitive use of grace periods. Grace periods similar to these are permitted at other facilities. The staff finds this acceptable.
3.0 ENVIRONMENTAL CONSIDERATION
This amendment changes recordkeeping, reporting, or administrative procedures or requirements. Accordingly, the amendment meets the eligibility criteria for categorical exclusion' set forth in 10 CFR 51.22(c)(10). Pursuant to 10 CFR 51.22(b), no environmental impact statement or environmental assessment need be prepared in connection with the issuance of this amendment.-

4.0 CONCLUSION
The staff has concluded, based on the considerations' discussed ab'ove, that (1) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner, and (2) such activities will be conducted in compliance with the Commission's regulations and the issuance of this amendment will not be inimical to the common defense and security or the health and safety of the public.
