SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION SUPPORTING AMENDMENT NO. 95 TO LICENSE NO. DPR-49 IOWA ELECTRIC LIGHT AND POWER COMPANY CENTRAL IOWA POWER COOPERATIVE CORN BELT POWER COOPERATIVE DUANE ARNOLD ENERGY CENTER DOCKET N0. 50-331 1.0 Introduction By letter dated December 20,1982(IELPNG-82-2761) the Iowa Electric Light and Power Company (the licensee) requested changes to the Technical Specifi-cations (Appendix A) appended to Facili6y Operating License No. DPR-49 for Duane Arnold Energy Center (DAEC). The proposed amendment and the revised Technical Specifications would incorporate the following administra-tive changes into the DAEC Technical Specifications: modifications made as part of Mark I Containment Modifications Program; removal of a reference to the Chairman of Safety Committee; additions complying with ANSI-N18.7; editorial changes to avoid a redundancy; :larif ccticn of Safety Committee quorum requirements; increase in Emergency Plan auditing frequency in com-pliance with 10CFR50.54(t); increase in Security Plan auditing frequency in compliance with 10CFR73.40(d); and a revision specifying frequency,of performing Design Change Request Safety Evaluation audits.
Since the receipt of the licensee's request, the affected pages were revised as a result of subsequently issued amendments 80 and 81. We have therefore based our review on the current version of the affected pages which differ from those submitted at the time of the. licensee's request.
2.0 Discussion The requested changes to the Technical Specifications were described in the Commissiomn's Notice of the licensee's application published pursuant to Public Law 97-415 on l
l 3.0 Evaluation The first proposed change revising tb Technical Specifications to clarify the Mark I Containment Modification Program, involves only the bases to the Technical Specifications.
Since no changes in Limiting Conditions:for Operation or Surveillance Requirements are involved, this change is deter-mined to be a clarification of existing Technical Specifications and as such is administrative. We have, therefore, determined that this change is acceptable.

- This second proposed change deletes the reference to the Chairman of the Security Committee to Plant Security Plan and Emergency Plan are no longer submitted to the Chairman of the Safety Committee.
Since the impacted function is not identified as a Safety Committee function, the deletion of reference to the Chairman of Safety Committee is considered to enhance con-sistency of the Technical Specifications. The reouested change is con-sidered administrative only and is acceptable to us.
The third proposed change adds non-destructive testing and administration under the review and audit functions of the Safety Committee to comply with ANSI-N18.7. The addition of this function to the Safety Committee review and audit authority will enhance quality of the non-destructive testing and administration, and is acceptable to us.
The fourth change deletes the list of items (a) through (g) from section 6.5.2.2 and references the same in section 6.5.2.1.
This change was re-quested to eliminate redundancy between the two sections and as such is considered administrative only.
This change is acceptable to us.
The fifth requested change, which clarifies the Safety Committee quorum requirements, has been previously approved by Amendment 80, dated January 7, 1983 and therefore is not considered in the Safety Evaluation.
The sixth proposed change increases the frequency of auditing the Emer-gency Plan to comply with 10CFR50.54(t) from once every 24 months to once every 12 months. This change would enhance the control on the quality of the energency plan and complies with the latest Commission regulations.
This change is therefore acceptable to us.
The seventh proposed change increases the frequency of auditing the Se-curity Plan to comply with 10CFR73.40(d) from once every 24 months to once every 12 months. This change is acceptable to us for the same reason as cited in the above paragraph.
The eighth proposed change specifies the frequency of performing design change request audits. This change was previously approved in Amendment 80, and is not considered in this Safety Evaluation.
l 4.0 Environmental Considerations We have determined that the amendment does not authorize a change in effluent types or total amounts nor an increase in power level and will not result in any significant environmental impact.
Having made this determination, we have further concluded that the amendment involves an action which is insignificant from the standpoint of. environmental impact, and pursuant to 10 CFR 651.5(d)(a), that an. environmental
. impact statement, or negative declaration and environmental impact appraisal need not be prepared in connection with the issuance of th.is amendment.
5.0 Conclusion We have 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 Commission's regulations, and the issuance of this amenoment will not be inimical to the common d2fense and security or to the health and safety of the public.
