PROPOSED ALTERNATE AMERICAN SOCIETY OF MECHANICAL  !

ENGINEERS BOILER AND PRESSURE VESSEL CODE (ASME CODE),

SECTION XI, EDITION FOR THE THIRD 10-YEAR INSPECTION INTERVAL CALVERT CLIFFS NUCLEAR POWER PLANT, UNIT NOS,1 AND 2 (TAC NOS. MA4647 AND MA4648)

Dear Mr. Cruse:

By letter dated June 16,1999, Baltimore Gas and Electric Company (the licensee) for Calvert l Cliffs Nuclear Power Plant, proposed an alternative to the requirements of 10 CFR 50.55a(g)(4) '

in regard to compliance with the latest approved edition of the ASME Code, Section XI, for the third 10-year inspection interval at Calvert Cliffs Units 1 and 2 beginning on July 1,1999.

Pursuant to 10 CFR 50.55a(g)(4)(ii), the applicable Code for inservice examination during the third 10-year inspection interval would be the 1983 Edition of the ASME Code, Section XI, which is currently incorporated by reference in 10 CFR 50.55a(b)(2). The licensee had earlier proposed in its submittal to the NRC dated January 29,1999, to adopt the 1998 Edition of the ASME Code, Section XI, for the third 10-year inspection interval and had provided a paragraph-by-paragraph analysis of the 1998 Code with that of the 1989 Edition which is currently being reviewed by the NRC. In the laterim, the licensee, therefore, proposes to continue with the use of the 1983 Edition of the ASME Code, Section XI with the Summer 1983 Addenda for all Class l 1,2, and 3 components at least through the upcoming Unit 1 refueling outage during the year 2000 and until such time into the interval that the NRC completes its review of the 1998 Edition of the ASME Code, Section XI. Further, the licensee has requested that inservice examinations performed during an inspection period under the 1983 Code and any additional examinations

! that the licensee selects to perform in accordance with the 1998 Code may be credited to the percentage requirement of the 1998 Edition of the ASME Code, Section XI, when approved.
