20555 IE Bulletin No.79-01B Supplement No. 3 Date:
October 24, 1980 Page 1 of 2 Description of Circumstances:
Two issues were raised by Supplement No. 2 which require clarification. These (1) the dates required for submittal of qualification information for are:
TMI reisted equipment, and (2) whether the equipment required to achieve a Cold Shutdown condition must be environmentally qualified if the licensing basis for the plant was a Hot Safe Shutdown condition.
(1) Supplement No. 2 (Q.1, Q.5) uddressed the minimum cold shutdown require-meats.
The staff position on this issue is that the licensee must identify and environmentally qualify the equipment needed to complete one method (path) of achieving and maintaining a cold shutdown condition.
The equipment of other paths must be reviewed to assure that its failure will not aggravate or contribute to the accident (ref. Q.5 Supplement No. 2).
Due to an inconsistency between Supplement No. 1 and Supplement No. 2, the staff position on this issue was unclear.
Therefore, the following will apply:
a.
The qualification information for equipment needed to achieve and maintain a Hot Safe Shutdown condition must be submitted not later than November 1, 1980.
b.
The qualification information for equipment required to achieve and maintain a Cold Shutdown condition (ref. Q.1 and Q.5 of Supplement No. 2) must be submitted not later than February 1,1981.
(2)
IEB 79-01B 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 be addressed in that response. Some of this equipment has since been ins talled.
Supplement No. 2 (Q.5, Q.21) identified that the staff posi-tion was that equipment which is installed should be traated in a manner similar to all other safety-related electrical equipment and be addressed in the November 1, 1980 submittal. This position represents no change in staff position regarding the scope of the review..However, since the staff position on this issue was unclear the following will apply:
x-IE Bulletin No.79-01B Supplement No. 3 Date: October 24, 1980 Page 2 of 2 Qualification information for installed TMI Action Plan equipment a.
must be submitted by February 1, 1981.
b.
' Qualification information for future TMI Action Plan equipment (ref.
NUREG-0737, when issued), which requires NRC pre-implementation review, must be submitted with the pre-implementation review data.
Qualification information for IMI Action Plan equipment currently c.
under NRC review should be submitted as soon as possible.
d.
Qualification information for TMI Action Plan equipment not yet installed which does not require pre-implementation review should be submitted to NRC for review by the implementation date.
The above items 1 and 2 represent no change in staff position regarding tne scope of the 79-013 Supplement 2 review.
IE Bulletin No. 79-013 was issued under a blanket GA0 clearance (3180225 (R0072), clearance expired July 31, 1980) specifically for identified generic problems.
Supplement No. 3 to Bulletin 79-013 is for information, hence no GAO clearance is required.
