Denotes those present at the exit interview on April 2,1993.

Other licensee-l

employees were contacted and interviewed during this inspection.

!

i 2.0 Pumose i

The purpose of this inspection was to review the licensee's ability to control and i

quantify effluent radioactive liquids and gases, and paniculates during normal and '

emergency operations.

'

3.0 hianagement Controls 3.1 Pmgram Changes q

The inspector reviewed the organization for administation of the radioactive'

t liquid and gaseous effluent control programs and discussed with the licensee.

any changes made since the last inspection conducted on September 23-27, j

1991. The inspector determined that the administration of the radioactive i

liquid and gaseous ef0uent control progmms remained the same as at the time

of the last inspection in this area.

3.2 Review of Radiological Semiannual Effluent Recons The inspector reviewed the semiannual radioactive effluent release repons for y

the second half of 1991 and all of 1992. The inspector also reviewed the annual radioactive effluents dose report for 1992. The annual radioactive

.

efnuent dose repon pmvided a summary of the assessment of the maximum l

individual dose resulting from routine radioactive airborne and liquid effluents.

The inspector determined that the licensee met the Technical Specification requirements and them were no anomalous measurements, omissions or trends in these repons.

3.)

Audit The inspector reviewed the 1992 Quality Assurance Audit Repon Numoer 92.

,

A06-OL This audit covered the radioactive liquid and gaseous effluent control programs, and the implementation of the Offsite Dose Calculation Manual (ODCM). - The inspector noted that the audit was conducted by the QA Depanment with assistance from other technical personnel. The inspector

noted that the audit covered the stated objectives and was very thorough and of.

i good technical depth. The audit identified one minor finding and one.

I observation which were not significant to public health 'and safety. The responsible department responded to these findings in a timely manner. The

inspector stated that the scope and technical depth of the audit were excellent to assess the radioactive liquid nd gaseous effluent control pmgrains.

4.0 Radioactive Liauid and Gaseous Ef0uent Control Programs

-

The inspector reviewed the following procedures and sew 8ed radioactive liquid and gaseous effluent release permits as pan of the examination of the implementation of Technical Specification and the ODCM tequirements.

i o CX 0917.01 Liquid Effluent Release o CS 0917.02 Gaseous Ef0uent Release-

o CS 0917.03 Unmonitored Plant Release i

o CS 0910.02 Gaseous Waste System Sampling o CS 0910.03-Liquid Waste System Sampling-a l

The inspector discussed with the licensee various aspects and actions regardmg

)

the above procedures. The inspector noted that the licensee understood these aspects and actions to be taken during normal and emergency operations. The J

inspector determined that the above effluent control procedures were j

sufficiently detailed to allow performance of all necessary steps. The inspector also determined that the reviewed radioactive liquid and gaseous effluent discharge permits were completed and met the Technical Specification requirements for sampling and analyses at the frequencies and lower limits of detection established in the Technical Specifications. The inspector had no

[

further questions in this area.

j

!

During discussions with the Chemistry Department staff, the inspector noted that the responsible individuals had excellent knowledge in the areas of: (1)

radioactive liquid and gaseous effluent controls, (2) effluent Radiation l

,

Monitoring Systems (RMS), (3) quantifying the total amount of liquid and i

gaseous effluent release using the RMS, (4) protection of the public health and

!

the environment, (5) actions to be taken for an unmonitored plant release, and (6) ODCM requirements.

j

Based on the review of the above procedures, release permits, and discussions

with the licensee, the inspector determined that the licensee implemented excellent radioactive liquid and gaseous effluent control programs.

5.0 Calibration of Effluent / Process Radiation Monitorine Systems (RMS)

The inspector reviewed the most recent calibration results for the following l

effluent / process RMS.

l

,

t o Steam Generator Blowdown Flash Tank Radiation Monitor (R-6519)

o Waste Liquid Test Tanks Radiation Monitor (R-6509)

-

o Turbine Building Sump Pump Radiation Monitor (R-6521)

o Primary Component Cooling Water Monitors (R-6515 & 6516)

o Containment Purge Radiation Monitors (R-6527-A & B)

o Plant Vent Wide Range Gas Monitor (R-6528)

o Condenser Air Evacuators Discharge Monitor (R-6505)

l

'

o Waste Gas Compressor Inlet Radiation Monitor (R-6503)

o Waste Gas Compressor Discharge Radiation Monitor (R-6504)

t

,

The I&C Department had the responsibility to perform electronic, radiological

.

and flow meter calibrations for the above RMS. All reviewed calibmtions-i were perfonned at the required frequencies and results were within the

!

licensee's established acceptance criteria. The inspector also reviewed selected

.l functional test results for several monitors and all reviewed results were within j

the licensee's acceptance criteria.

!

During the review of radiological calibration results, the inspector independently verified several calibration results including linearity tests and

'

conversion factors. Using the licensee's raw data, the inspector perfonned

!

statistical analyses (linear regression) for comparison. The inspector i

detennined that these independent comparisons were excellent. The inspector

,

discussed with the licensee the benefit of using a statistical method (e.g., linear j

regression method) to detennine the linearity and the conversion factor. The

-

licensee stated that the method will be evaluated and incorporated in the near

'

future.

-l Based on the above reviews, the inspector determined that the licensee has an j

effective calibration progam for the effluent / process radiation monitors.

.I 6.0 A_ir Cleaning Systems I

The inspector reviewed the licensee's most recent surveillance results for the following air cleaning systems as part of the examination of the implementation of the q

Technimi Specification requirements and FSAR commitments.

l

'

(1) Containment Purge Exhaust
