Subject:

Calvert Clifis Nuclear Power Plant Unit No.1; Docket No. 50-317 Request for License Amendment Gentlemen:

Baltimore Gas and Electric Company hereby requests an Amendment for Operating License DPR-53, for Calvert Cliffs Unit No.1, with the submittal of the enclosed proposed change to the Technical Specifications.

PROPOSED CHANGE Revise Technical Specification 3.6.1.6, Limiting Condition for Operation for Containment Structural Integrity, to allow a specified time period for the performance of an engineering evaluation of potentially abnormal conditions detected during surveillances of the containment post tensioning system. The purpose of this change is to ensure that plant shutdown is only required for conditions indicating an abnormal trend or phenomena which could adversely affect the ability of the containment to perform its design function.

Revise Technical Specification 4.6.1.6.1, Surveillance Requirements for Containment Tendons, to more clearly identify those conditions that shall be considered as evidence of possible abnormal degradation of the containment structure and to include time-dependent limits for lift-off forces (tension levels) for tendons within each of the three tendon groups (dome, vertical and hoop).

A copy of the existing and the proposed technical specifications are provided for your use as Enclosures I and 2, respectively. The extent of the proposed changes precludes a simple markup of the existing specification for your review purposes.

S DISCUSSION AND 3USTIFICATION

< (/O Enclosure 3 presents a detailed background discussion of the need for the changes, a comparsion between the existing and the proposed specifications, and an evaluation of the impact of the changes on safety.
