1.0 INTRODUCTION

By letter dated March 10, 1995, IES Utilities Inc. submitted a request for revision of the Technical Specifications (TS) for the Duane Arnold Energy Center (DAEC).

The proposed changes remcve redundant requirements for containment hydrogen and oxygen analyzers. Surveillance Requirements cited in TS Section 4.7.H.3 are redundant to the requirements of Table 4.2-H in the DAEC TS. Table 4.2-H requires a semiannual test of the containment hydrogen and' oxygen analyzers. This duplicates and exceeds the requirement for an annual functional test required in TS Section 4.7.H.3.

TS Section 3.7.H.3 refers directly to Table 3.2-H for Limiting Conditions for Operation.

Therefore, deleting TS Sections 3.7/4.7.H.3 will eliminate redundant requirements without reducing the frequency of equipment testing or changing the applicable Limiting Conditions for Operation.

These changes are consistent with the BWR/4 Draft Improved Technical Specifications, NUREG-1433.

2.0 EVALVATION The proposed change in the DAEC TS removes redundant Limiting Conditions for Operation and Surveillance Requirements for the containment hydrogen and oxygen analyzers.

This change does not reduce the frequency or modify the type of testing of equipment.

Based on this information, the staff finds the proposed changes to the DAEC TS acceptable.
