1.
DEFUELING The two-week data acquisition outage was ccmpleted on Sunday,
,,m February 22, 1987. Video inspection results of the reactor coolant system c.old leg piping and reactor coolant pumps showed a laycr of i pf very finely divided material. Similar naterial was found in the "B" not leg. The decay heat drop line was full of material of i
'd apparently larger average particle size. Video surveys of the top
?
of the current core, the core support assembly and lower reactor t
w vessel head were also obtained. Localized damage including melting of incore instrument guide tubes and small portions of the CSA were.
i-observed.
The information gathered will be of significant value in planning further defueling activities and in understanding the n-P course of the accident at TNI-2.
.F Defueling operations will resume on February 23, 1987 with a day of l'
defueling training followed by fuel removal activities.

ENVIROCENTAL MONITORING I..
!?
US Environmental Protection Agency (EPA) sample analysis results U
show that TMI site liquid effluents are in accordance with 40 regulatory limits, NRC requirements, and the City of Lancaster fF' Agreement.
TMI water effluents are sampled from the station (Units 1 and 2) discharge and analyzed by EPA. Gama spectrum analyses of the seven daily composited samples for January 31 - February 7,1937 indicated
- 6 no TMI-2 related radioactivity.
f EPA's gama spectrum analysis of the NRC's TMI outdoor air sample
- 1-for the period February 12 - 19, 1987 showed no reactor related iW radioactivity, j?;
The Lancaster water works intake composited seven daily samples February 1 - 7, 1987. The garma spectrum analyzed by EPA showed no reactor related radicactivity.
