SUBJECT:
I&E Inspection Report 81-28
REFERENCE:
NRC Letter Dated February 17, 1982 (G-82051)
Dear Mr. Collins:
This letter is in response to the Notice of Violation received as a result of the inspection conducted by Messr.'s B. Murray and W. L. Holley of your staff on December 7-11, 1981.
The following response to the item contained in the Notice of Violation is hereby submitted:
1.
Technical Specification LCO 4.8.1(c) states in part:
" Plant equipment in the helium purification system
(... including the titanium sponge),
.shall be utilized to keep releases of radioactive materials to unrestricted areas as low as practicable.
Contrary to the above, the titanium sponge in the helium purification system has not been in operation since April, 1980.
This is a Severity Level V Violation (Supplement I).
8205070352 820401 PDR ADOCK 05000267 0
. (1) The corrective steps which have been taken and the results achieved:
Titanium sponge has been placed in the helium purification system and is available for use upon activation of the system. The system is currently not in use, as the PCRV is depressurized.
This pla es us in compliance with LCO 4.8.1(c).
(2) The corrective steps which will be taken to avoid further violations:
This Technical Specification will be evaluated to determine the need for having operable titanium sponge in the helium purification system.
Based on a review of effluent discharges from Fort St. Vrain in the 20 months between April 1980 and January 1982, approximately 370 curies of tritium were released via the liquid waste discharge path, while approximately 14 curies were released via the gas waste discharge path.
In the 20 months preceeding April 1980, approximately 4 curies of tritium were released via the gas waste discharge path, while the titanium sponge was in service.
The electrical generation of the plant for the above two time periods was approximately 1,300,000 MWH (net) and 565,000 MWH (net), re3pectively.
From the above information it can be seen that:
a.) Tritium in the primary coolant is being removed in the liquid form prior to reaching the titanium sponge; and b.) The curies of gaseous tritium, released per net MWH for periods when the titanium sponge was in service and was out of service are essentially the same.
Based on the above preliminary evaluation, we feel that the presence or absence of the titanium sponge has little effect on gaseous tritium release, and we seriously question the need for the present. Technical Specification.
We will in all probability, be requesting a change to this Technical Specification in the immediate future.
. (3) The date when full compliance will be achieved:
Full compliance was achieved when the titanium sponge was returned to service on March 10, 1982.
Should you have any further questions, please contact Mr. Edwin D. Hill, (303) 571-7436, Ext. 218.
Very truly yours, O. R. Lee Vice President ORL/skd
