Other licensee employees were contacted and interviewed during this inspection.
2.0 PURPOSE The purpose of this inspection was to review the licensee's capability to implement the radioactive liquid and gaseous effluent control programs required by the Technical Specifications (TS) during normal and emergency operations.
3.0 MANAGEMENT CONTROLS 3.1 PROGRAM CHANGES The inspector reviewed the organization and administration of the radioactive liquid and gaseous effluent control programs and asked the licensee if any program changes were made since the previous inspection conducted in August 1993.
The inspector determined that the organization and administt ative control of these programs have not changed since the last inspection.
The Chemistry Department still has the responsibility to implement the radioactive liquid and gaseous effluent control program AUDITS 3. 3 The inspector reviewed the 1 icensee '
1 993 NgA Audit (Audit ¹ : 93-141 )
and 1 994 N(A Audit (Audit ¹: 94-1 1 0 ) for the radioactive effluent control programs as part of the evaluation of the impl ementat ion of the TS requirements
.
These audits were performed by Nuclear gual ity Assurance (NgA) Department personnel with assistance from other technical experts.
No findings were identified during these audits.
'everal observations were made for enhancing the effluent control programs, however, none of them had a safety significance.
The inspector noted that the NgA personnel used a tracki ng system to follow the status of findings, if any.
The inspector determined that the aud its were of sufficient technical depth and detail to assess the effluent control programs.
The inspector also reviewed the 1 995 gA Audit Report Number 95-1 1 for the contractor laboratory, Teledyne Brown Engineering.
No findings were made, but minor deficiencies were identified.
These were non-s afety related.
Based on the above reviews, the inspector determi ned that the licensee had implemented the gA Audit Program very effectively.
REVIEW OF THE ANNUAL RADIOACTIVE EFFLUENT RELEASE REPORTS The inspector reviewed the 1 993 and 1 994 Annual Effluent Release Reports.
These reports provided total released radioactivity for liquid and gaseous effluents
, including pr ojected radiation exposures to the public.
Projected dose calculation results to the public were listed in these reports and the results were well below regulatory limits (about 0. 0 1X of the limits specified in the ODCH).
The inspector al so revi ewed available 1 995 effluent r el ease records and determined that these records did not contain anomalous measurements or omissions.
4.0 4.1 Based on the review of reports and records, and discussions with licensee personnel, the inspector determined that the licensee met the TS reporti ng requirements
.
RADIOACTIVE LI UID AND GASEOUS EFFLUENT CONTROL PROGRANS TOUR The inspector toured radioactive liquid process facilities including:
radioactive liquid effluent radiation monitoring station, sampling station, mixed ion exchange bed, and the Radwaste Operation Control Room.
All equipment was operable at the time of the tou.2 IMPLEMENTATION OF THE EFFLUENT CONTROL PROGRAMS The inspector reviewed selected radioactive liquid and gaseous discharge permits and the associated procedures as part of the examination of the implementation of the TS and the Offsite Dose Calculation Manual (ODCH)
requirements for both units.
The inspector noted that the reviewed effluent control procedures were detailed and well written to allow performance of all necessary steps.
The inspector also determined that the reviewed discharge permits were completed appropriately and met the TS/ODCM requirements for sampling and analysis frequency, and for lower limits of detection.
As part of the examination of the implementation of the radioactive liquid effluent control program, the inspector reviewed ten Condition Reports issued during March, April, and Hay 1995.
Condition Reports were being used as part of a programmatic tracking of any task, system, or program weakness.
For example, these ten Condition Reports related to the radioactive liquid effluent control program [e.g.,
(a) liquid radwaste surge tank overflowed, (b) liquid radwaste discharge line isolated due to high radiation monitoring system (RHS) response, and (c)
inoperable liquid radwaste effluent flow recorder].
The root causes of these reports appeared to be either (1) contamination of the liquid radwaste system piping or (2) mechanical problems associated with the radwaste system.
The inspector reviewed the licensee's investigation results and determined:
1.
2.
3.
4.
No radwaste releases occurred; The licensee employed excellent investigation processes; The RHS responded as expected; and Corrective actions included replacement of a filter, and replacement or decontamination of piping.
The inspector noted further that the Chemistry Department personnel conducting the radioactive liquid and gaseous effluent control programs maintained excellent knowledge in the areas of:
1.
2.
3.
Radwaste system operation, Quantifying the total amount of gaseous effluent release using RHS, and TS and ODCH requirements.
4.3 As a result, the licensee appropriately maintained protection of the public health and the environment.
QUALITY CONTROL OF ANALYTICALMEASUREMENTS FOR THE EFFLUENT SAMPLES The inspector reviewed the licensee's quality control (gC) program of analytical measurements for effluent samples to determine whether the licensee had adequate control with respect to sampling, analyzing, and evaluating data for the implementation of the effluent control programs.
The gC program for analyses of effluent samples was conducted by a
contractor (Analytics, Inc.). The gC program consisted of measurements
g.4 of spike samples for all effluent matrices, such as water, particulate filters, and charcoal cartridges.
These spike samples were prepared by the contractor and analyzed by the licensee and the contractor laboratory, Teledyne.
The analytical results were sent to the contractor and the contractor compared the results.
All analytical comparisons for 1994 and the first quarter of 1995 were in agreement CONCLUSIONS 5.0 Based on the above tour, record reviews, and discussions with personnel, the inspector determined that the licensee continued to implement excellent radioactive liquid and gaseous effluent control programs.
CALIBRATION OF EFFLUENT/PROCESS RADIATION MONITORS The inspector reviewed the most recent calibration results for the following radiation effluent/process monitors to determine the implementation of the Technical Specification requirements for both units.
o Liquid Radwaste Effluent Monitor (common to both units)
o Service Water Effluent Monitors o
RHR Service Water Radiation Honitors o Hain Steam Line Monitors o Standby Gas Treatment Vent Monitors (common to both units)
o Reactor Building Vent Noble Gas Monitors (low, mid, and high ranges)
o Turbine Building Vent Noble Gas Monitors (low, mid, and high ranges)
The Chemistry and the 18C Departments had the responsibilities to perform radiological and electronic calibrations, respectively, for the above monitors.
During the review of the calibration results, the inspector noted that the radiological calibration technique for the liquid radwaste and service water effluent monitor continued to be excellent.
Radiological calibrations of the liquid radwaste effluent monitor were primary and secondary calibrations using a mockup system and solid button sources.
The mockup calibration standards contained (1) Cd-109 for low gamma energy, (2) Cs-137 for medium gamma energy, and (3) Co-60 for high gamma energy, and the sources were traceable to the National Institute of Standards and Technology (HIST).
Then five solid button sources (Cs-137)
were used to obtain a secondary calibration factor.
All reviewed calibration results were within the licensee's acceptance criteria.
Based on the above review and discussions with the licensee, the inspector determined that the licensee had excellent calibration techniques and appropriately implemented these techniques for the above monitor.0 AIR CLEANING SYSTENS The inspector reviewed the licensee's most recent surveillance test results for the following systems to determine the implementation of the Technical Specification requirements:
(1) control room emergency outside air supply system, and (2) standby gas treatment system.
For the above systems, the inspector reviewed the surveillance test results of the following inspections and tests:
o Visual Inspection, o In-Place HEPA Leak Tests, o In-Place Charcoal Leak Tests,
'o System Air Flow Rate Tests, o Pressure Drop Tests, and o Laboratory Tests for the Iodine Collection Efficiencies.
The inspector noted that the licensee performed these surveillance tests more frequently than Technical Specification requirements and also met Technical Specification acceptance criteria.
The inspector also discussed with the licensee other aspects of the air cleaning system, such as the plant air balance and system enhancements implemented by the licensee.
The inspector noted that the System Engineer had excellent knowledge of the system, and also was knowledgeable of the current industry practices applicable to the system.
Based on the above review and discussions with the licensee, the inspector determined that the licensee had an excellent air cleaning system program.
8. 0 EXIT INTERVIEW The inspector met with the licensee representatives denoted in Section 1. 1 of this inspection report at the conclusion of the inspection on July 28, 1995.
The inspector summarized the purpose, scope, and findings of the inspection.
The licensee acknowledged the inspection findings.
