DEFUELING t..j
?
Defueling activities to date have resulted in approximately 19 A
percent (57,279 lbs.) of_ the total core debris being loaded into defueling canisters. Two shipments, involving three loaded shipping k, ;
casks, have resulted in-the transfer of approximately 4 percent (12,000 lbs.) of the core debris to the Idaho National Engineering Laboratory.
The licensee has issued (10/8/86) a revised Program 11 aster Schedule for the THI-2 cleanup project. The latest schedule continues to project the current phase of the cleanup to be complete by the end of the third quarter of CY 1988. ~In-vessel and ex-vessel defueling completion dates, however, have been delayed approximately 21 months to mid-December 1987.
Pick and place dafueling has been discontinued to perform a core debris bed video survey. The video survey is used to verify the T,1 absence of end fittings on the debris bed prior to core bore operations. End fittings can cause rapid degradation of drill bit cutting rates. Any end fittings observed during the video survey P'
will be removed.
Installation of the drilling rig is expected for f
the week of October 13, 1986.

ENVIRONt1 ENTAL MONITORING p
b US Environmental Protection Agency (EPA) sample analysis results W
show that THI site liquid effluents are in accordance with f
regulatory limits, NRC requirements, and The City of Lancaster Agreement.
The Lancaster water sample taken at the water works river intake and analyzed by EPA consisted of a seven day composite sa.aple taken D
September 20 - 27, 1986. A gamma scan detected no reactor related activity.

October 10, 1986 Frank J. Miraglf a flRC/TilI-86-100 Tl1I water sanples teken by EPA at the plant discharge (includes Units 1 and 2) to the river consisted of seven daily composite scaples taken fro:n Septcaber 20 - 27, 1986. A gama scan detected no reactor related activity except.
The EPA analyses of the llRC outdoor air sanple for the period October 2 - 10, 1986 showed that cancentrations of Cs-137 and I-131 were below the lower liait of quantitative detection (LLD) for the system. The LLO varies around a value of 1E-13 uCi/cc.

PUBLIC MEETIliG The Advisory Panel for the Decontamination of Three l111e Island Unit 2 not on October 0, 1986 in Harrisburg. At the meeting the licensee briefed the Panel on the progress of defueling and on the status of furding for the remainder of the cleanup. The EPA presented the results of its recent revitu of the TMI offsite radiation nonitoring program.
The next panel meeting is t6ntatively scheduled for December 10, 1986.
At that meeting the licensee will give a presentation en their licensing subnittal for the Post Defueling Plant Status. That submittal is schaduled for issue to the !!CC staff in Nove.aber.
