IIIMEDIATE PRELIMINARY NOTIFICATION May 29, 1979 PRELIMINARY NOTIFICATION OF AN EVENT OR UNUSUAL OCCUR!tENCE -- PNO-79-67AQ Ihis preliminary notification provides updated information of safety or public interest significance.
Facility: Three Mile Island Unit 2 Middletown, Pennsylvania (DN 50-320)
Subject:
NUCI. EAR INCIDENT AT THREE MILE ISL\\ND Operational:
1.
The average coolant temperature is 158 degrees F and being maintained around that temperature by natural circulation.
Pressure is about 450 psi with the pressurirer in solid operation.
Steam 1s being admitted to the main condenser through the turbine bypass valve from the A Steam Generator.
The highest incore temperature reading is 291*F.
2.
Water 1cvel in the reactor building is being measured daily, and was 6.8 feet above floor level this morning.
The lowest decay heat nyatem motor-(~.
operated valve (DH-V2) in the reactor building was opened on May 25 as a precautionary ceasure, due to increasing water level.
Secondary cources of water into the reactor building have since been isolated, including the fan coolers water supply, to reduce water in-leakage.
3.
Preoperational testing is in progress for the Spent Fuel Pool Tank Farm, Once-Through Steam Generator "B" Long-Term Cooling System, and the codified rad waste treatment system (EPICOR). The testing is scheduled for completion by June 1.
Environmental Status Environmental radiation levels continue to be consistent with natural background levels. A slight change in background level on May 24 and 25 was shown to be due to changing levels of naturally occurring Rn-222 caused by a weather front moving through the area.
Airbdene releases have been below Technical Specification limits. During the period May 21-23, approximately 35 air samples were collected by the NRC and all were less than MDA. Vegeta-tion and milk samples collected during this period also showed no activity above MDA. EPA air, water and milk samples collected during this past week tr to May 24 showed no detectable activity f rom TMI.
The State of New Jersey reported that they detected no I-131 in any of the 83 s milk samples they analyzed between March 29, 1979 and April 24, 1979. These samples included milk from counties within 50 miles of Harrisburg, Pennsylvania and supplied to New Jersey consumers, the Salem, New Jersey area, and northern
