PLANT STATUS
,

s
'
'
The facility remains in long term cold shutdown with the Reactor
-
i Coolant System (RCS) vented to the reactor building atmosphere and
'y the reactor vessel head and plenum assembly removed from the reactor
.
a:
vessel.
- .
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).
C
-
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
1 defueling.
~;'
Calculated reactor decay heat is less than 12 kilowatts.
-
RCS cooling is by natural heat loss to the reactor building ambient
-
atmosphere, Incore thermocouple readings range from 70*F to 91*F
'
with an average of 79 F.
Average cold leg temperature will no
'~k longer be reported.
.g The average reactor building temperature is 56*F. The reactor
-
,',
building airborne activity is 4.8 E-9 uC1/cc Tritium and 1.5 E-10
,, ;..
uCi/cc particulate, predominantly Cesium 137, 2.
WASTE MANAGEMENT if
.The Submerged Demineralizer System (SDS) commenced processing batch
-
\\>p.
124 from neutralizer tanks (WDL-T-8 A/B) to SDS monitor tanks
',
(SDS-T-l'A/3). To date 3,036 gallons from this batch have been processed.

EPICOR II comacaced processing batch 267 frem CC-T-1 to CC-T-2.
To
-
date 16,296 gallons from this batch have been processed.
Total volume processed through SDS to date is 2,631,270 gallons, and
-
the total volume processed through EPICOR II is 2,96o,411 gallons.
3.
DOSE REDUCTIO!l/DECONTAhl4ATION ACTIVITIES
-
Decontamination activities are continuing on the 281' level of the auxiliary building.
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 building.
4.
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 accurate.
5.
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 Agreement.
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 activity.
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 radioactivity.
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 detectability.

REACTOR BUILDIliG ACTIVITIES Defueling Water Cleanup System (DWCS) preoperational testing and
-
modification continued.
-
Work is in progress on the canister positioning systen and canister handling bridge.
Installation of the vacuum defueling system is in progress.
-
7.
AUXILIARY AND FUEL HANDLING BUILDING ACTIVITIES Installation of the D'.lCS continued.
Partial DWCS turnover for
-
processing RCS during early defueling is expected to be co@leted in October.
All four of the fuel canister storage racks have been inspected.
-
Three of the four fuel canister storage racks have been positioned in the spent fuel pool "A" and their position is being adjusted.
The fourth rack has been installed into the fuel pool.
