Harold R. Denton, Director Office of Nuclear Reactor Regulation Frank J. Miraglia, Director Division of PWR Licensing-B FR0il:
William D. Travers, Director THI-2 Cleanup Project Directorate
SUBJECT:
NRC Tt!I-2 CLEANUP PROJECT DIRECTORATE WEEKLY STATUS REPORT FOR AUGUST 30 - SEPTEMBER 7, 1986 1.
DEFUELIliG Bulk defueling operations continue. New tools have not been successful in increasing the rate of naterial placed in canisters.
Progress has been slow because of the difficulty breaking the crust ar.d interference frca fused upper end fittings, and continued poor visibility.
2.
PLANT STATUS The reactor renains in long tena cold shutdown, vented to the alNosphere.
Core cooling is by natural heat loss to arabient building atmosphere. The average incore thernoccuple reading is 79"F.
The airborne radioactivity on the defueling platform above the reactor vessel is about 4.9 E-7 uC1/cc Tritium and 2.6 E-10 uCi/cc particulates, predominately Cesium-137 and Strontium-90. About 15 feet of water over the core region and 6 feet over the carousel holding the defueling canisters provide shielding.

$8 on US Environmental Protection Agency (EPA) sample analysis results W
show that TMI site liquid effluents are in accordance with y
regulatory limits, NRC requircaents, and The City of Lancaster oo Agrecuent.
The Lancaster water sample taken at the water works river intake and g
analyzed by EPA consisted of a seven day composite sar:ple taken om August 17 - 23, 1986. A gar.na scan detected no reactor related j@@g activity.

The EPA analyses of the i;RC outdoor air sample for the periods August 21 - 29 and August 29 - Septeaber 4, 1986 showed that concentrations of Cs-137 and I-131 vere below the lower limit of quantitative detection (LLD) for the systen. The LLD varies around 1E-13 uCi/cc.
