IMMEDIATE PRELIMINARY NCTIFICATION June 13, 1979 PRELIMINARY NOTIFICATION OF AN EVENT OR UNUSUAL OCCURilENCE -- PNO-79-67AT This preliminary notification provides updated information of safety or public interest sis;nificance.
Facility: Three Mile Island Unit 2 Middletown, Pennsylvania (DN-50-320)
Subiect:
h'UCLEAR INCIDENT AT TICIEE MILE ISLAND
@erational:
1.
The average coolant temperature is 155 degrees F and the highest incore thernoccuple temperature reading is 273 degrees 7.
Core cooling is beicg r:.sintained by natural circulation.
Pressure is about 350 psi with the pressurizer in solid operation.
Steam is being admitted to the :cain con-denser through the turbine bypass valve from the A Steam Generator.
2.
Reactor building water level is being ceasured daily, and is ncv 7.0 1 0.5 feet above' fic>r level.
This lower than previously reported level is due to refine =e of the measurecent technique, and does not reflect an acutal level dec; ease.
3.
Preoperational testing for the Spent Fuel Pool Tank Farm, Once-Through Steaa Generator "B" Long-Term Coolina System, the modified radwaste treatment. system (EPICOR), and the pressure / volume control sycten pro-grossed slowly during the past week due to various eperational/procuresent problems encountered.
The testing may be completed within the next two weeks.
Ecviron: catal Status:
Environnental radiatiou levels recain consistent
.tural background levels.
Airborne releases have been below Technic acciiication limits.
From June 11-17, 42 cir samples, 2 milk sa=ples, 4.egetation samples and 2 soil sniples were collected by the h~dC.
All analytical results were less than MDA. IPA air, water and milk samples collected during the week (up to June 15) showed no detectable activity frco TMI.
