0FFICE OF INSPECTION A'O ENFORCEMENT REGION III May 29, 1979 IE Information Notice No. 79-13 INDICATION OF LOW WATER LEVEL IN THE OYSTER CREEK REACTOR Su==ary A loss of feedwater transient at the Oyster Creek facility on May 2, 1979, resulted in a significant reduction in water inventory within the reactor core shroud area as reasured by one set of water level instruments (triple low level), while the remaining level instrucents, sensing from the reactor annulus area indicated water levels above any protective feature setpoint (Figure 1). Tiie water level within the core shroud area was reduced below the " triple low level" retpoint of 4-feet, 8-inches above the top of the fuel. Subsequent analysis by the licensee has determined that the minicu= collapsed water level (solid, without steam voids) over the top of the fuel was 1 to 1-1/2 feet. Coolant sample analyses and offgas release rates do not indicate any fuel damage occurred. General Oyster Creek is a non-jet pump BWR with licensed power of 1930 MWt. The plant was first u.ade critical May 3, 1969. Status Before Transient Operating at near full power with the main parameters at levels as follows: 1895 MWt power level 79" Yarway (13'4" over top of fuel) reactor water level 1020 psig reactor pressure 7.1x106 f/hr feedflow 14.8x104 gpm recirculation flow rate (4 pumps) 2288 223 12 psid core op Eguipment Out of Service (00s) DUPLICATE DOCUMENT "D" recire pump OOS due to sea "B" startup transformer DOS fo Entire document previously entered into system under:
