MEMORANDUM FOR:

D. Ziemann, Chief, Operating Reactors Branch #2, DOR FROM:

G. Lainas, Chief, Plant Systens Branch, 00R

SUBJECT:

OYSTER CREEK CONTROL ROOM VENTILATICH SYSTEM Our fire protection SER for Oyster Creek dated March 3,1978, indicated that Jersey Central Power and Light Corpany (JCPSL) would install isolation dampers in the exhaust ductwork for the cable spreading room and control roca ventilation s/ sten to limit recirculation of smoke between these areas. By letter of Cecember 28,1979, JCP&L orovided further datails on ventilation system rodifications for these areas. The modifications include: autonatic tripping of the suoply fan to the control roon and cable spreading room by sroke detectors in these areas.. installation of a sroke detector in the control roca supply air duct that will autonatically trip the supply fan; and installation of a back-draft prevention type snoke damper in the return air register in the contml room. To provide even greater assurance that snoke from a fire will not inhibit control roca operations, JCP1L has also procosed to install a smoke removal fan in the exhaust duct that can be actuated ranually.

'cle find that these modifications to the ventilation system for the contml room and cable spreading roo-' will provide the crotection the staff intended in preparing the Oyster Creek fire protection SER, and are therefore, acceptable.
