IN5:ECTION RE00IREF.EV 5 TO REVIEW LICENSEE ACTION 5 IN RESPONSE TO IE BULLETIh NO. E0-24 I.
Obie::ive Ine cbje::ive of this inspe:: ion is :: verify that the a: ions required by IE Ecile:in 80-24 have oeen satisfa::crily completec, that suitably ce Eile descriptions of open cooling sy.tems within containment are provioed as requirec, and tna; acceptacle cocumentation is provided by
- ne licensee.
Additionally, since tne Coomissioners have requestec a summary briefing "within three or four days' of receipt of the licensee's submittals, the Inspector is requested to compile and submit the information oescribec in Section IV below.
This TI is provided te supplement IE Pro:eoure 92703E, whose general guidance should be followed during this inspection.
II.
Backcround Information IE Sulletin 80-24 was issued November 21,193C, to operating reactors.
Tne basis of the bulletin is unoetected accumulation of a sio~nificant amount cf water in the Indian Point Unit 2 containment that was discovered 0:tocer 17,1980.
III. Descriotion of NRC Insoection to Determine Acceotability of Licensee's Pian: Eculement anc Licensee's Resoonse tc Bulle:1n 80-24 The following describes acceptable li:ensee responses to Bulletin 80-24 in terms of Doth the written response to be submitted by the licensee and in terms of acceptable equipment recuired at the piant.
Plant specific unique situations should be consioered and accounted for as appropriate.
The NRC inspection should verify that the plant equipment and the licensee's written Bulletin response is acceptably similar to that discussed below.
NOTE: The numbered items below correspond to numbered " Actions to be Taken by Licensees" in IE Bulletin 80-24:
1.(a) Flow paths and eouioment used (pumps, piping, valves, sumps) should De described.
Separate descriptions for normal and post-LOCA operations should be included.
P & ID's with the flow paths marked are oesirable for a thorough but concise response.
(b) Self-explanatory (c) Service water system materials in contact with the water shoulc be listed; other materiais need no: De listec.

Tne licensee's escenses shoulc characterize the frecuencv and magnituos of isaks frer closed systems in containment.
M'agnituoe snould inclues flow ra e ana/or a cnaracterization of the leak as a " wet spot," "oripping", "small" or "large stream," "ceiuge,"
etc.
Responses shoule also describe how the leak was aetected (from inventory decrease, makeuo flow to system, sump level increase, etc.).
Any oamage causec by the leak to the ciesec' system or to eccipment in the vicinity cf the leak shoulc be oescriDed.
IV.
Recortinc Reovirements Tne Commissioners have requestea that tney oe briefed regarding results of this Bulletin "within three or four days" of the licensee submittals.
Accordingly, it is requested that the Inspector compile the information described below and submit it by January 9, 1981 (licensee responses are due January 5,1981) following as closely as possible the outline below.
The intent of the requested report is to provide a concise summary of the' most important pcrtions of the licensee's submittal in a format that will enable quick preparation of one sumr..ary covering all plants.
It is realizec that in all cases the exact format will not be completely appropriate.
however, please stay as close tc the forma: as possible to maintain tne usefulness of the report in quickly preparing the required material for the Commissioners.
1 NOTE: the numbered items below correspond to the numbered " Actions to be Taken by Licensees" in IE bulletin 80-14.
