• Denotes those present at the exit meeting on January 28, 1988, Purpose The purpose of this routine inspection was to review the licensee's radioactive effluent controls program for the following eierents:

-

Effluent Release Records and Reports

-

Effluent Sampling and Analysis

-

Offsite Dose Calculation Manual Implementation

-

Radioactive Waste System Operations 3.0 Status of Previously Identified items 3,1 (Closed) Unresolved Item (50-213/85-08-03), "Develop procedures covering preparation of Quality Control (QC) Samples." The inspector reviewed two procedures:

-ES-511,"Preparation of Radioactive Solutions", and-ES-512. "Preparation of Spikes and Splits" and found them adequat This item is close .2 (0 pen) Inspector Follow-Up Item (50-213/85-08-04), "Review Meteoroingical System Calibration Following Cable Switchover; Review-Licensee Actions to Ensure Reliable Data Transmission." The inspector noted the licensee's capabil!ty to receive the meteorological data using a phone / modem interface data link in the control room. This is the short-tem fix; the long tem fix - a real time monitoring system has not yet been installed but has been scheduled, 4.0 Effluent Release Records and Reports The inspector reviewed selected radioactive liquid, gaseous and particulate release discharge permits, as well as associated procedures, analysis printouts and calculations for 1987. The inspector also reviewed the licensee's Semi-Annual Effluent Report (for January-June, 1987)issuedAugust 28, 198 .

'

L The inspector determined that no Technical Specificaticn limits were exceeded in 198 The inspector verified that the radioactive waste treatment systems were used for all releases during the sane time perio The inspector performed dose calculations for gaseous and liquid releases as a spot chec Gaseous Releases:

With regard to

{ gaseous discharges, no concerns were identifie The inspector identified a concern regarding the steam generator blowdown discharge pathwa Technical Specification 7/8.2.1, "Radioactive Liquid Effluent Instrumentation" applicability requirements are established in Table 7.2- The automatic termination of blowdown requirement of these specifications is not currently in effect but will become effective upon i completion of a planred systen redification. Under the current system, uson receipt of a high alarn, the licensee samples the blowdown and, if

"

t1e activity exceeds limits, the flow is diverted to the Aerated Waste

Tank (AWT). Discharge continues until the sample is analyzed. If limits

are exceeded, discharge is terminated. During the tine the sample is being analyzed, limits could be exceeded. This concern was expressed to the licensee at the exit meeting and the Station Superintendent determined

. that, in the future, the flow would first be diverted to the AWT and then i sampled / analyze .0 Effluent Samplina and Analysis Program

specifications in the Radiological Environmental Monitoring

Offsite Dose Calculation Manual (REMODCM). The inspector also reviewed selected procedures including the following:

-SUR 5.4-4, "Reactor Coolant, RWST, BAMT and RHR Chemistry Surveillance"

-SUR 5.4-13. "Liquid Radwaste Release Surveillance"

-SUR 5.4-14. "Gaseous Radwaste Release Surveillance"

-SUR 5.4-18 "Surveillance of Unmonitored Potential Radioactive Release Paths"

-SUR 5.4-21, "Sampling and Analysis of Containment Purges"

-SUR 5.4-23, "Waste Gas Decay Tank Sampling and Analysis"

-SUR 5.4-24, "Main Stack Sampling and Compositing"

-SUR 5.4-27, "Test Tank Sampling and Analysis" Within the scope of this review, no violations were note The inspector noted a strength in the analysis progran in that the licensee is perfoming radioanalytical deteminations of Fe-55, Sr-89, and Sr-90 rather than using a vendor laborator This provides a greater control of quality results and decreases the time to obtain and use analysis results for determination of compliance and offsite dose .0 Radiation Monitoring Systy (RMS)

The inspector reviewed the licensee's perfomance for compliance with Technical Specification Surveillance requirements for the RM Tables 8.2-1 and 8.2-2 provide channel check, source check, channel calibration and functional test requirements for the liquid and gaseous effluent monitors, respectivel The inspector detemined that all surveillances were performed as required in 198 The inspector identified two weaknesses pertaining to RMS calibrations and test ) The licensee is required to use only one source that is traceable to 1 the National Bureau of Standards (NBS) for celibrating gaseous monitor '

Kr-85 is used as the NBS traceable source. The isotope Xe-133 is also used for calibration by taking a sanple of the waste gas decay tank (WGDT)

which contains Xe-133 which has been isolated long enough to allow short lived isotopes to decay. An aliquot of the sample is analyzed in the chemistry lab and then another portion of the sample is used for calibra-tion. Because the lab uses liquid standards for primary calibration, an approximate 20 to 30% error is introduced (in the conservative direction)

which will result in higher activities and doses calculated than the true values using the Xe-133 metho ) The inspector reviewed an I & C calibration procedure, SUR-5.2-81,"RMS Calib ration. " Section six of this procedure provides instructions and applicability to radiation monitors of various types. GM, scintillation, etc. The inspector noted an absence of deteil regarding CM detectors for ;

I which the procedure states "perfocm plateau if required", without stating !

! the nothod or when a plateau is required. The inspector discussed this t l with Instrument and Control Personne! who were fully krewledgeable as to l j what a plateau was but specific critaria as to when a plateau is required ;

3 were limited to faulty detectors and did not include criteria such as gain

or voltage changes. The licensee stated that they would consider ,

modifying their procedures in this area, i

Within the scope of this review, no violations were noted.

i i 7.0 Air Cleaning System j

'

i The inspector reviewed the licensee's program for compliance with Technical i Specification 4.4, "Containment Testing" paragraph IV, "Air Filtration i System."

l The Containment Air Recirculation System (CAR) recirculation fan darper

'

test and filter inspection (monthly) ard filter challenge (refueling ;

i cycle) tests and records were reviewed by the inspector. The operations !

group perforns the monthly surveillances and a contractor is used for the i filter challenge tests under the auspice' of the In Service Inspection !

(ISI) grou '

I The January 1988 monthly surveillance and refueling cycle records fron

July to September 1987, were reviewed. The inspector noted that the  ;

! licensee had cetermined that one of the accumulated run thers indicated J greater than 720 hours0.00833 days <br />0.2 hours <br />0.00119 weeks <br />2.7396e-4 months <br /> had clapsed on the Number 1 fan of the CAR. On 11/4/87, the licensee issued Plant Incident Report Number EN-87-1072 on j this event. The root cause of this was that the face damper which i l initiates tirer operation was open, but fans were not actually running, i

j i

Concomitant with the efforts that determined that the run time did not !

exceed 720 hours0.00833 days <br />0.2 hours <br />0.00119 weeks <br />2.7396e-4 months <br />, the charcoal beds were changed and a subsequent Filter !

challenge test series performed 11/10 to 11/20/8 !

Within the scope of this review, no violations were note !

i j 8.0 Audits .

<

)i The inspector reviewed the licensee's audit program as it pertained to radiological effluents. The Ouality Assurance group performed audit  !

!' number A25002 frem Fay 5, 1986 to June 17, 1986, satisfying the Technical t l Specification Requirenent in 6.5.2.8 for biennial reviews of the  !

implementation of the REMODCM. The inspector noted that the scope of the ;

i audit was thorough and findings were, in most cases, adequately resolved l

in a timely manner. Audit number A25019, conducted from October 22, 1987 ;

to January 28, 1908 was a comprehensive review of the Radiological '
