Dear Mr. Keppler:
MONTICELLO NUCLEAR GENERATING PLANT Docket No. 50-263 License No. DPR-22 The reviews and evaluation requested in items 1 through 3 of IE Bulletin 75-04 have been completed for the Monticello Nuclear Generating Plant.
In accordance with item 4 of the Bulletin, the results of these reviews and evaluation are hereby submitted.
Existing Administrative Directives governing installation and test procedures require identification of unusual mechanical, cicetrical, chemical, thermal, or other hazards associated with equipment and its environs.
Instructions and precautions necessary to control these hazards are required to be included fu the procedures. Existing Directives and instructions governing work authorizations require a second IcVel of review by technical and operating personnel prior to commencing work related to equipment, instruments, and systems which are designated on a " critical" list. Cabic spreading room penetrations have been added to this list.
Design of the floor and wall penetrations in the cabic spreading room requires the penetrations be covered with a non-flammable material.
Inveatigation revealed that penetrations which were scaled or rescaled subsequent to completion of original construction were scaled with a flame retardent material. A non-flammabic covering has been applied to these penetrations.
A task force has been designated to review the areas identified in IE Bulletin 7 5-04 A. Their review is expected to be completed by June 30, 1975.
Yours very truly,
$.tol&
