Dear Ms. Barickman:
This letter provides a response to your letter of June 25, 1980, with regard to
the May 10, 1980 event at Arkansas Nuclear One, Unit 1.
Enclosed you will find a copy of the Licensee Event Report Number 80-015/01-0
dated May 19, 1980.
The licensee is still evaluating this event and will submit
a supplemental report. We have also enclosed a copy of our inspection report
number 50-313/80-07,50-368/80-07.
Section 10 of this report contains information
pretaining to the May 10, 1980 event.
You also asked some specific questions regarding this event. We have provided
answers to these questions below.
1.
Is the water (57,700 gallons spilled onto the reactor building floor) still
in a holding tank on the reactor site? Will it be recycled to cool the
reactor or released into Lake Dardenelle?
Ans.-All of the spilled water was reprocessed and reused.
40,000 gallons of this
water was returned to the borated water storage tank (BWST) and the remainder
was returned to the reactor coolant system.
None of the water was released
to Lake Dandenelle.
After the 57,700 gallons of water was reprocessed approximately 3000 gallons
of water was used to clean and decontaminate the reactor building.
This
water was processed and released to the lake.
2.
What is the radioactive content of the water?
Ans.-The spilled water was analyzed prior to processing and had the following
activity levels:
Isotope
Activity (microcuries/cc)
O.9753
'
Iodine-133
.
0.7166
Xenon-133
/
0.155

After the. water was processed it was analyzed and found to have the
following activity levels:
Isotope
Activity (microcuries/cc)
3
1.054X10 4
Iodine-133
1.866X10-
Xenon-133
8.308X10-2
Total Activity

.
3.
How many curies of Tritiu::1 does it contain?
Ans.-The spilled water was not analyzed for Tritium content.
4.
How many curies of noble gases were released from the containment building?
Ans.-A total of 2423.91 curies of noble gas were released.
The majority
(2322 curies) of the noble gas was Xenon-133.
Other isotope included in
the noble gases released were:
Xenon-131M
Xenon-133M
Xenon-135
I hope t*~t the above information satisfies your concerns.
If we can be
of any f ,i ther assistance, please do not hesitate to contact this office.
