Oyster Creek Nuclear Generating Station Sp;cial Report Report Date: February 18, 1993 Occurrence Datc February 4,1993 Identification of Occurrence:
The Control Room Heating, Ventilation, and Air Conditioning (HVAC) System 'B' was inoperable for a period greater than 7 days. This is a condition which requires a special report per Oyster Creek Technical Specification 3.17.B (2).
Dese_ription of Occurrence; On January 28,1993 the 'B' Control Room HVAC System did not pass the acceptance criteria of Procedure 654.3.006 (Control Room HVAC " System B" Flow and Differential Pressure Test) and was declared inoperable. A system walkdown was conducted and a broken access hatch was discovered on the Control Room supply duct downstream of the
'B' HVAC Fan. This created an open now path to the environment, resulting in low flow to the Control Room and a reduced differential pressure across the Control Room doors. A work request was submitted on the same day to fix the broken access hatch.
The access hatch on the 'B' HVAC System was repaired and the system was declared operable after successfully passing the acceptance criteria of the surveillance procedure on February ll,1993.
As required by section 3.17.B(1) of the Technical Specifications, the A Control Room HVAC system was tested daily in the partial recirculation mode to verify system operability.
