The facility remains in long term cold shutdown with the Reactor

The plenum is on its storage stand in the deep end of the fuel transfer canal. A dam has been installed between the deep and

'

t shallow ends of the fuel transfer canal. The deep end is filled with water to a depth of about 20 feet (about 5 feet above the top of the plenum).

The modified internals indexing fixture is installed on the reactor

vessel flange and is flooded to elevation 327 feet 6 inches (151 n feet above the top of the core region). The defueling platform is

y installed over the Internal Indexing Fixture in preparation for

-

Decontamination activities are continuing on the 281' level of the auxiliary buildin Average general area radiation dose rate is 40 meen per hour on the 347' level of the reactor building and is 67 mrea per hour on the 305' level of the reactor buildin . STRONTIUM-90 INSPECTION

-

A special inspection was conducted on Septercher 30 through October 2,1935 to review the licensee's report that due to nisinterpretation of a calibration procedure, the Strontium-90 (Sr-90) activities reported for some solid waste shipments were one-half the actual activities. The inspectors also reviewed the licensee's efforts to determine the extent of the corrections which may be needed. The licensee agreed to perform an independent assessment of the chemistry Quality Assurance / Quality Control (QA/QC) program; inplement a formalized QA/QC program; ard to assure that all procedures used at TMI-2 for Sr-90 analyses are clear and accurat . ENVIRONMENTAL i;0NITORI!!G

US Environmental Protection Agency (EPA) sample analysis results show THI site liquid effluents to be in accordance with regulatory linits, NRC requirements, and the City of Lancastar Agreemen TMI water sacples taken by EPA at the plant discharge to the river consisted of seven daily composite samples taken from Septeober 14 through September 21, 1985. A gama scan detected no reactor related activit The Lancaster water sample taken at the water works intake and analyzed by EPA consisted of a sesen day composited sample taken frco Septenber 15 through September 21, 1985. A garna scan detected no reactor related radioactivit The NRC outdoor cirborne particulate sampler at the THI Site collected a sample between September 25 and October 2,1985. Ilo reactor related radioactivity was detected. Analysis showed lodine-131 and Cesium-137 concentrations to be less than the lower limits of detectabilit "'CE > ........... ............. ............ .............. ............. ............. .............
