NUCLEAR INCIDENT AT TIIREE MILE ISLAND Operationa_1_:
1.
Th? average coolant temperature is 155 degrees F and thn highest incore thern couple temperature reading is 273 degrees F.
Core cooling is being m:.siotained by natural circulation.
Pressure is about 350 psi with th-pressurizer in solid operation.
Steam is being admitted to the main con-denser through the turbine bypass valve from the A Steam Generator.
2.
Reactor building vater Icvel is being measured daily, and is new 7.0 t 0.5 feet above' floor level.
This lower than previously reported level is
~
due to refinement of the measurement technique, and does not reflect an acutal level decrease.
3.
Preoperational testing for the Spent Fuel Pool Tank Faro, once-Through Stesa Generator "B" Long-Term Cooling System, the modified radwaste treatment system (EPICOR), and the pressure / volume control system pro-grassed slowly during the past week due to various operational / procurement problems encountered. The testing may be completed within the next two weeks.
EcViron:leatal Status:
Enviro ne stal radiation levels recain consistent with natural background levels.
Airborne releases have been below Technical Specification limits.
Froa June 11-17, 42 air samples, 2 milk sar.:ples, 4 vegetation sas:ples and 2 soil sn..ples were collected by the NRC.
