NUCLEAR INCIDENT AT THREE MILE ISLAND
@erational:
1.
The average coolant temperature is 155 degrees F and thn highest incare ther:ncouple temperature reading is 273 degrees ?.
Core cooling is being r:.sintained by natural circule. tion.
Pressure is about 350 psi with the pressurizer in solid operation.
Steam is being admitted to the main con-denser through the turbine bypass valve from the A Steata Generator.
2.
Reactor building water Icvel is being ceasured daily, and is nev 7.0 i 0.5 feet abovi~ floor level.
This lower than previously report :d level is due to refinement of the measurement technique, and does not reflect an acutal level decrease.
3.
Preoperational testin2 for the Spent Fuel Pool Tank Faro, once-Through Steaa Generator "B" Long-Term Coolina System, the clodified radwaste treatment system (EPICOR) and the pressure /voluc:e control system pro-gressed slowly during the past week due to various operational / procurement problems encoantered. The testing may be completed within the next two weeks.
Ecvirom:2eatal Status:
Enviro mental radiation levels remain con:istent with natural background levels.
Airborne releases have been below Technical Specification limita.
Froa June 11-17, 42 air samples, 2 milk sample;, A vegetation samples and 2 soil sr.ples were collected by the NRC.
