:Two issues were raised by Supplement No. 2 which require clarification. Theseare: (1) the dates required for submittal of qualification information forTMI related equipment, and (2) whether the equipment required to achieve aCold Shutdown condition must be environmentally qualified if the licensingbasis for the plant was a Hot Safe Shutdown condition.(1) Supplement No. 2 (Q.l, Q.5) addressed the minimum cold shutdown require-ments. The staff position on this issue is that the licensee mustidentify and environmentally qualify the equipment needed tocomplete one method (path) of achieving and maintaining a cold shutdowncondition. The equipment of other paths must be reviewed to assure thatits failure will not aggravate or contribute to the accident (ref.Q.5 Supp. No. 2).Due to an inconsistency between Supplement No. 1 and Supplement No. 2,the staff position on this issue was unclear. Therefore, the followingwill apply:a. The qualification information for equipment needed to achieve andmaintain a Hot Safe Shutdown condition must be submitted not laterthan November 1, 1980.b. The qualification information for equipment required to achieve andmaintain a Cold Shutdown condition (ref. Q.1 and Q.5 of SupplementNo. 2) must be submitted not later than February 1, 1981.(2) IEB 79-O1B required a 90 day response which was due in mid-April 1980.Supplement 1 (Feb. 1980) informed licensees that equipment which was"planned" to be installed as a result of lessons learned need not beaddressed in that response. Some of this equipment has since beeninstalled. Supplement No. 2 (Q.5, Q.21) identified that the staff posi-tion was that equipment which is installed should be treated in a mannersimilar to all other safety-related electrical equipment and be addressedin the November 1, 1980 submittal.

Description of Circumstances
- Two issues were raised by Supplement No. 2 which require clarification. Theseare: (1) the dates required for submittal of qualification information forTMI related equipment, and (2) whether the equipment required to achieve aCold Shutdown condition must be environmentally qualified if the licensingbasis for the plant was a Hot Safe Shutdown condition.(1) Supplement No. 2 (Q.l, Q.5) addressed the minimum cold shutdown require-ments. The staff position on this issue is that the licensee mustidentify and environmentally qualify the equipment needed tocomplete one method (path) of achieving and maintaining a cold shutdowncondition. The equipment of other paths must be reviewed to assure thatits failure will not aggravate or contribute to the accident (ref.Q.5 Supp. No. 2).Due to an inconsistency between Supplement No. 1 and Supplement No. 2,the staff position on this issue was unclear. Therefore, the followingwill apply:a. The qualification information for equipment needed to achieve andmaintain a Hot Safe Shutdown condition must be submitted not laterthan November 1, 1980.b. The qualification information for equipment required to achieve andmaintain a Cold Shutdown condition (ref. Q.1 and Q.5 of SupplementNo. 2) must be submitted not later than February 1, 1981.(2) IEB 79-O1B required a 90 day response which was due in mid-April 1980.Supplement 1 (Feb. 1980) informed licensees that equipment which was"planned" to be installed as a result of lessons learned need not beaddressed in that response. Some of this equipment has since beeninstalled. Supplement No. 2 (Q.5, Q.21) identified that the staff posi-tion was that equipment which is installed should be treated in a mannersimilar to all other safety-related electrical equipment and be addressedin the November 1, 1980 submittal. This position represents no change instaff position regarding the scope of the review. However, since thestaff position on this issue was unclear the following will apply:a. Qualification information for installed TMI Action Plan equipmentmust be submitted by February 1, 1981.b. Qualification information for future TMI Action Plan equipment (ref.NUREG-0737, when issued), which requires NRC pre-implementationreview, must be submitted with the pre-implementation review data.
IEB 79-Ol Sup #3October 24, 1980 c. Qualification information for TMI Action Plan equipment currentlyunder NRC review should be submitted as soon as possible.d. Qualification information for TMI Action Plan equipment not yetinstalled which does not require pre-implementation review should besubmitted to NRC for review by the implementation date.The above items 1 and 2 represent no change in staff position regarding thescope of the 79-OlB Supplement 2 review.IE Bulletin No. 79-OIB was issued under a blanket GAO clearance (8180225(R0072), clearance expired July 31, 1980) specifically for identified genericproblems.
