NUCLEAR INCIDENT AT T/REE MILE ISLAFD Overstional:
1.
The average coolant temperature is 157 degrees F.
The highest incore thermocouple temperature reading is 280 degrees F.
Core cooling is being
=aintained by ratural circulation. Pressure is about 340 psi with the pressurizer in solid operation.
Steam is being admitted to the e.ain con-denser through the turbine bypass valve from the A Steam Generator.
2.
Vater level in the reactor building is being measured daily, and is 7.3 feet above floor level this corning.
3.
Preoperational testing for the Spent Fuel Pool Tank Farrs, Once-Through Steam Generator "B" I.ong-Term Cooling System, the modified rad waste treat =ent system (EPICOR), and the pressure / volume cont.rol system should be completed by June 15.
Envirenoental Status:
Environ = ental radiation levels remain consistent with natural background levels.
Airborne releases have been below Technical Specification limits. From June 5 -
June 10, about 37 air samples were collected by the NRC.
