Operational:
1, The average coolant temperature is being maintained at 170 degrees F by natural circulation.
Pressure is about 300 psi.
steam is being admitted to the main condenser through the turbine bypass valves from the A Steam Generator. Tie highest incore temperature reading is 301 degrees F.
2.
Hydrostatic testing of the existing decay heat removal system "B" loop
~
has been performed satisfactorily.
Leaks have been identified and are being corrected in the "A" loop.
3.
The pressurizer has been taken " solid" periodically to obtain confirmatory information on pressurizer level and to check primary sys'em leak rate.
4.
The water level in th'e reactor building was measured and found to be 6.1' above floor level.
This is about 450,000 gallons.
5.
One of two primary system pressure indications now in use is giving erratic readings. Direct reading pressure gages can be connected to the system if needed.
Environmental. Status Environmental radiation levels continue to be consistent with natural background levels. Approximately six minor releases have occurred during the past week (May 14-20) in conjunction with changing levels in the primary make-up tank and sampling the primary system. Aerial and ground surveys taken during these releases indicated no radiation levels above background, except for a release at 1300 on May 16, when an aerial measurement above the stack read 0.05 mR/hr.
No radiation was detected on the ground.
During the period May 14-20, approxi.-
mately 36 air sa=ples were collected and all were less than MDA.
Vegetation -
and milk samples collected during this period also showed no activity above HDA. ' EPA and FDA air, water milk and food samples collected during this past week up to May 19 showed no detectable activity from TMI.
