Letter dated 6/30/87 from JEGagliardo, NRC, to BDWithers, WCNOC Subj :
Response to Deviation 482/8712-02 l
Gentlemen:
Attached is a detailed response to deviation (482/8712-02) which was documented in the Reference.
The deviation concerns a failure to keep the Continuous Airborne Radioactivity Monitors operating as specified in the Updated Safety Analysis Report.
If you have any questions concerning this l
matter, please contact me or Mr. O. L. Maynard of my staff.
Very truly yours, l

Deviation (482/8712-02): Failure to Implement a Continuous Airborne
]
Monitoring Program Finding:
l The USAR for the Wolf Creek Generating Station, Section (WCGS),
Section 12.3.4.2.2.2.9, portable monitors, und Section 12.5.2.1, health physics equipment and instrumentation, establish a commitment to use Continuous Airborne Radioactivity Monitors (CAMS) as a primary means of measuring and trending airborne radioactivity concentrations at five specific locations:
the 1974-foot elevation in the auxiliary building, the 2000-foot elevation j
in the auxiliary building - north and south ends, the 1976-foot elevation in I
the radwaste building, and the 2047-foot elevation in the fuel building, l
l 1
In deviation from the above, the NRC inspectors determined on May 20,
- 1987, that the licensee did not have operable CAMS available to measure and trend l
airborne radioactivity for the 2000 foot elevation. in the auxiliary
- building, the 1976-foot elevation in the radwaste building, and the 2047-foot elevation in the fuel building.
This is a repeat deviation previously identified in NRC Inspection Report 50-482/8542-01.

)
Reason For Deviation:
The Updated Safety Analysis Report, (USAfi), Section 12.5.2.1 describes the Continuous Airborne Radioactivity Monitors, as a three (3) channel monitor.
The TEAC CAMS used at Wolf Creek Generating Station have i
experienced numerous operational and maintenance problems which have resulted in an excest',e amonnt of down time. This excessive amount of down I
time is a deviation of the USAR commitment to have operating CAMS in l
specific areas to provide. airborne monitoring.
Corrective Steps Which Have Been Taken and Results Achieved:
Continuous Composite Air Samples are pulled and analyzed on a daily basis in the five specific locations:
the 1974 foot elevation in the auxiliary building, the 2000 foot elevation in the auxiliary building; north and south j
- ends, the 1976 foot elevation in the radwaste building, and the 2047 foot i
elevation in the fuel building.
This sampling is performed whether or not the CAMS are operating.
A change so tne USAR has been initiated which will allow the use of single i
or multi channel CAMS.
The use of a single or dual channel CAM will allow for continuous measuring and trending of airborne concentration when the three channel CAM is not functioning.
Corrective Steps Which Will Be Taken To Avoid Further Deviations:
WCGS Health Physics personnel are continuing to work with the TEAC CAM manufacturer to improve the units reliability.
Continuous Composite Air l
Samples in the five areas will continue to be pulled and analyzed on a daily basis.
A single channel CAM or multi channel CAM will be used in the five arear to comply with the commitment to have five CAMS operating, t

1 The Date When Full Compliance Will Be Achieved:
Full compliance has been achieved when the USAR. change which allows use of single or multi channel CAMS is approved by Wolf Creek Nuclear Operating Corporation. This will be done by August 31, 1987.
