PP.ELIMINARY NOTIFICATION OF EVENT OR UNUSUAL OCCORED:CE== PNO-70-67AN (Carre This preliminary notification constitutes summary information of an event of safety or public interest signific_ance.
Facility:
Three Mile Island.Unir. 2 Middletown, Pennsylvania (DN 50-320)
Subject:
NUCLEAR INCIDENT AT T1012E MII.E ISLWD
~.
Operational Status 1.
The average coolant temperature is being maintained at 170 degrees F
~
by natural circulation.
Preasure is about 650 psi.
Steam is being admitted to the main condenser through the turbine bypass valves from the A Steam Generatcr. The highest incore temperature read-ing is 308 degrees F.
2.
All four trains of the independent, additional charcoal filter system are presently operable. Normally three trains are operating at any one time to provide additional filtration for the entire gas-cous effluent flow from Unit 2.
Iodine concentrations in the gas-eous effluent have been below instantaneous release limits and below detectable levels most of the time.
3.
Preliminary hydrostatic testing of the existing decay heat removal r"
system ("A" and "B" loops) has been performed.
Leaks have been identified and are being corrected.
4.
The pressurizer has been taken " solid" periodical)- to obtain con-firmatory information on pressurizer level and to check primary system leak rate.
5.
Measurements of the liquid level inside containment is planned in the near futuro by measuring the hydtuataLit Lead una Lhe nump discharge piping using a recently installed Heise gage.
Environmental Status Environmental radiation levels continue to be consistent with natural back-ground levels.
There were approximately four minor releases during the past week (May 7-13, 1979) associated with venting of the primary makeup tank and work on the new r11ter train system anc monttors.
During this period 14 24-hour continuous air samples and 27 air. grab (1 to 2 hr.) samples were collected, and all were less than MDA. A goat milk sample taken on May 8, 1979 contained an I-131 concentration of 12 pCi/ liter.
The latest goat milk sample collected and analyzed on May 13 showed less than MDA for I-131 (F10 pCi/1).
Grass samples taken at the goat farm showed I-131 levels less than MDA.
Cow milk samples and grass samples from other locations show less than MDA levels for I-131.
Ground surveys continued to show radiation to be at background levels. Aerial surveillance flights have not shown any levels of I-131 above MDA. Other Federal Agencies have not reported any positive values for samples taken during this period.
