Subject:
NUCLEAR INCIDENT AT THREE MILE ISLAND 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 pressurizer in solid operation. Steam in 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 level in the reactor building is being measured daily, and was 6.8 feet above floor level this morning. The lowe9* decay heat system motor-operated valve (DH-V2) in the reactor building was opened on May 25 as a precautionary ceasure, due to increasing water level. Secondary sources of water into the reactor building have since been isolated, including 3 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 modified rad waste treatment system (EPICOR). The testing is scheduled for con:pletion by June 1. Environmental Status Environmental radiation levels contirue to te consistent with natural background levels. A slight change in background level on May 24 and 25 vas shown to be due to changing levels of naturally occurring Ra-222 caused by a weather front movirrg through the area. Airborne releases have been below Technical Specification limits. During the period May 21-28, approximately 35 air samples were collected by the NRC and all were less than HDA. Vegeta-tion and milk samples collected durin;; this period also showed no activity above MDA. EPA air, water and milk samples collected during this past week up to May 24 showed no detectable activity from TMI.
