May 19, 1979 MEMORANDUM FOR: Victor St.ello FROM:
Richard H. Vollmer
.i
SUBJECT:
'DII DAILY REPORT A.
Reactor and Plant Status 1.
Operations found a large diameter penetration of the RB near the water on the floor that might be used to insert a probe and measure radiation levels.
Possibility being pursued.
Dome monitor reading has decreased - will look for half life correlation.
2.
Decay Heat Loop A seems leak tight except for bonnet leak on valve. Will fix and try again.
Pressure. decay was ~ 15#
in several hours. DH-V6B seems to be tight based on pressure test and rad surveys.
3.
Status of modifications as indicated in attach =ent.
No major problems but minor ones will likely cause a couple day slip.
These dates correspond to turnover to operations following a functional test.
4.
Reactor Coolant and "A" Bleed Tank samples were taken 5/18 at 9:00 a.m.
Results are as follows:

Reactor Status - At 373# with a bubble and drifting toward 300#. Bypass valve now 567. closed. See attachme.at for details of reactor and releases.

Radwaste and EP 2
1.
On May 18 some workers without respirators entered an Aux Building area requiring respiratory protection after getting
~
lost. After being in the area for approximately two minutes,
they found their way to the Health Physics check point.
Whole body counts revealed a maximum intake of 16 nci of I-131 2.
Met-Ed is trying to operate the compactor 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> per day to rid themselves of the backlog of low-level trash. More druns, approximately 29, were moved to the paint shed en May 19, bringing the inventory to 89.
It is anticipated that Met-Ed may resolve the problems concerning the shipment of solid radwaste and that shipments may resume next week.
C.
Environmene veasurement, 1.
Grounu surveys made between 1200, 5/18/79 and 1200, 5/19/79 on both the east and west side of the river showed no levels above a background of 0.02 mR/hr.
2~
Two milk samples collected on 5/17 and counted on 5/18 showed no I-131 over the MDL of 10.5 picoeuries per liter. A grass sample collected near the south gate showed no I-131 activity over the MDL of LE-4 microcuries per square meter.
3.
The three 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> air senples showed no I-131 above the MDL of 1E-12 microcuries per milliliter.
Three grab samples showed no I-131 above the MDL of 6E-12 microcuries per milliliter.
