1.0 INTRODUCTION

By application dated March 20, 1984, and modified by letter dated August 24, 1984, Dairyland Power Cooperative (DPCI (the licenseel requested a change to Provisional Operatino License No. DPR-45 of the la Crosse Boiling Water Reactor (LAC 8WRI.

This amendment would incorporate the reporting requirements of 10 CFR 50.73 and would also add details on the reouirements of the report to be submitted to the NRC on each failure of a diesel generator. Th'roughout the Technical Specifications (TS) references to Reportable Occurrences would be changed to reflect the terminology and reporting requirements of 10 CFR 50.73. There are changes to the Definitions section, Action Statennts Surveillance Requirements, and Administrative Controls of the LACnWR Appendix A TS.

7.0 EVALUATION In Generic letter (GL) 83-43, dated December 19, 1983, the Commission stated that Section 50.7? of Title 10 of the Code of the Federal Regula-tions was revised and a new Section 50.73 was added, effective January 1, 1984 Section 50.72 revises the immediate notification requirement for operating nuclear power reactors and Section 50.73 provides for a revised License Event Report System.

The Comission requested licensees to propose revisions to the "Adminis-trative Controls" and " Definitions" sections of th ir plant's TS to implement the 50.73 requiation changes.

(; 'f ,..

The licensee proposed to add the following definition to Section 4.0.1, Definitions: Reportable Event, a REPORTABLE EVENT shall be any of those conditions specified in Section 50.73 to 10 CFR Part 50. A Licensee Event Report shall be submitted for REPORTABLE EVENTS. The first sentence of the licensee proposed definition is the NRC recomended definition. Since the second sentence is accurate and provides continuity for the use of the term " Licensee Event Report," this definition is acceptable to the staff.

The Commission requested in Generic Letter 83-43 that the licensee revise the responsibilities of the Unit Review Group and Company and Puclear >

Review and Audit Group to include review of all Reportable Events. The licensee proposed to revise the responsibilities of its respective ,

, Operations Review Comittee and Safety Review Comittee to do this.

The Comission requested in GL 83-43 that the licensee revise TS Section l 6.6, Reportable Event Action, to implement the regulation changes to 10 CFR 50.73. The licensee proposed words which are consistent with guidance in GL 83-43 for this section.

The Comission requested in GL 83-43 that the licensee delete the TS '

Section on Reportable Occurrences, with its references to prompt notification with written followup and thirty-day written reports. .The licensee has proposed to delete this section.

The Comission requested in GL P3-43 that TS Section 6.10.1, Record Retention, item c, be revised to state "All Reportable Events." This was requested to maintain the new nomencisture of Reportable Events of 10 CFR 50.72 and 50.73 throughout the TS. The licensee proposed to revise the item accordingly.

The licensee also r.-: posed changes to other sections to reflect the terminology and reporting requirements of 10 CFR 50.73, as requested by Generic letter 83 43. The sections modified were: 4.2.2.22, 4.2.17, 4.2.18.1, 4 4.2.18.2, 4.2.18.3, 4.2.18.5, 5.2.10.1.4, 4.2.21 and Bases 4/5.2.18. These l chances are acceptable to the staff as they implement the request of the l Generic Letter.

j One of the affected sections was 5.7.10.1.4 on diesel generator failure reports. The licensee's existing wording did not correctly identify the ,

i basis for the reporting requirement. The licensee submitted a proposed a revision to 5.2.10.1.4 in its August 24, 1984 letter which included this

! information. The staff finds the wording in the August 24, 1984 submittal j to be acceptable.

In submitting a change to Section 4.2 21, Emergency Service Water Supply System..due to Generic Letter 83-43, the licensee also clarified wording in the Limiting Condition for Operation (LCO). The wording change was minor, but better reflects the actual system and how it is described in the Bases. The staff finds this minor word change acceptable.

Based on the above, the staff concludes the changes proposed by the licensee to implement the 50.73 regulation changes are acceptable. The addition of detail in the report requirements for diesel generator failures and the minor wording change in the Emergency Service Water Supply System LCO are also acceptable.

3.0 ENVIRONMENTAL CONSIDERATION

4.0 CONCLUSION

The staff has concluded, based on the considerations discussed above, 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 Comission's regulations and the issuance of this amendment will not be inimical to the comon defense and security nor to the health and safety of the public.
