+ 6 Novemb r 28, 1986 MEMORANDUM FOR: Sholly Coordinator Distribution 6 Docket F,11e "PKreutzer FROM: Ashok C. Thadani, Director 'NRC/L'oial'PDR'~DSells PWR Project Directorate #8 OGC-Bethesda Sholly File Division of PWR Licensing-B Sholly Coord.

SUBJECT:

REQUEST FOR PUBLICATION IN BIWEEKLY FR NOTICE - NOTICE OF CONSIDERATION OF ISSUANCE OF AMENDMENT TO FACILITY OPERATING LICENSE AND PROPOSED NO SIGNIFICANT HAZARDS CONSIDERATION DETERMINATION AND OPPORTUNITY FOR HEARING Omaha Public Power District, Docket No. 50-285, Fort Calhoun Station, Unit No. 1, Washington County, Nebraska Date of amendment request: November 5, 1986 Description of amendment request: The amendment would change Section 3 of the Technical Specifications to incorporate revisions to the surveillance criteria for the steam generator tube inspections. The change would remove Section 3.3(2) and Table 3-8 from Section 3.3 and put them into a new section, Section 3.17. The change would correct the criteria for Sample Selection and Inspection Results from fixed numerical criteria to comparable percentages. This would acommodate steam generator tube inspection where the sample size has been increased from the minimum size required by the Technical Specification and regulatory commitments.

Basis for proposed no significant hazards consideration determination: The

staff has completed its preliminary review of the proposed changes and

oncluded that the changes meet the criteria of 10 CFR 50.92. A discussion of the criteria follows

(i) Involve any significant increase in the probability or consequences of an accident-previously evaluated.

-2 The change affects the organization of the Technical Specifications and not the contents of the sections involved. It would affect those inspections where the sample size exceeds the minimum size used as a basis for the previous evaluation increasing the reliability of the inspection results.

This will not affect any of the sssumptions or conditions that were used in the analyses used for licensing the plant. Therefore, there will be no significant increase in the probability or consequences of accidents previously evaluated.

(ii) Create the possibility of a new or different kind of accident from any accident previously evaluated.

Since this change does not change the surveillance requirements and will not affect the assumptions or operating conditions in the plant, no new path is created that could lead to a new or different kind of accident from any previously evaluated.

(iii) Involve any reduction in the margin of safety.

The main purpose of this change is to remove the steam generator tube inspection requirements from Section 3.3 to a new section, Section 3.17, that is dedicated specifically to steam generator tube inspection. This does not change the surveillance requirements. For the larger sample sizes addressed in the change, the inspection reliability is greater. Since this, I along with the fact that assumptions and operating conditions used in the analysis of the plant are not affected, the margin of safety will not be affected in a positive or negative manner.

. \

In addition, the Commission has provided guidance concerning the application of the standards for determining whether a significant hazards consideration exists by providing certain examples (51 FR 7751) of amendments that are considered not likely to involve significant hazards considerations. Example (i) relates to a change which is administrative in nature, intended to achieve consistency or a change in nomenclature. The proposed change is representative of Example (i) in that it moves the steam generator tube inspection requirements from Section 3.3 to a new section, Section 3.17.

Based on the above, the Commission proposes to determine that the proposed amendment involves no significant hazards considerations.
