2.0 Status of Previously_ Identified j (Closed) Inspector Follow-Up Item (50-423/86-06-02):  !

Licensee to implement a program to compare radiation monitor readings to actual samples. The licensee compares gaseous samples monthly and liquid samples are compared during each release. This item is close ,

(Closed) Inspector Follow-Up Item (50-423/86-16-01):  !'

Review licensee's actions to resolve ALARA concerns on taking reactor coolant sample from the hot leg. The licensee has blanked off the sample line from the hot leg and is using a sample from the cold le Dose i rates have been reduced from 900 mR/ hour to 5-10 mR/hr. This item is l close l (Closed) Inspector Follow-Up Item (50-423/86-16-03): i Licensee to correct deficiencies in hot well sampling for detecting steam l condensor tube leaks. The licensee has modified the system, increasing ;

flow rates on the system and decreasing the time to detect which ;

condensor is affected by about a factor of five. This item is closed, i l

(Closed) Inspector Follow-Up Item (50-423/86-16):  !

Licensee to resolve sulphate problem in steam generators. The licensee determined th1t a sulfonated organic group existed on the resins used in the condensate polishing system and has changed to a d iferent nuclear i grade resin. This resulted in a change in seconda.y water conditions from 10-15 parts per billion (ppb), which o :eedeJ the steam generator owner's group guidelines to 2-3 ppb, which is well within the guid This item is close >

3.0 Chemistry The inspector reviewed-the licensee's organization for implementing the effluents control program. The Assistant Supervisor, Chemistry is ~

responsible for implementing the day to day program. This individual reports to the Chemistry Supervisor who reports to the Station Services Superintenden The. licensee uses a Master Surveillance Schedule, ACP-QA-9.02C.to implement the routine. surveillance tasks. LC0 driven requirements are controlled within the department as neede The licensee implements a chemistry controls program using procedures, CP3802C, "Chemistry Controls" and NE0 2.17 "Secondary Water Chemistry Program" in control of Primary and Secondary Coolants, Balance of Plant (80P) and steam generator owner's group (SG0G) guideline The licensee implements inter-and intra-laboratory quality control programs using split sample spikes and unknowns. With. regard to vendor activities, monthly duplicates are used to evaluate precision ano semi-annual spikes for accuracy. The inspector noted that the May, 1987 spiked sample was biased by 40% for Sr-8 '

The licensee stated that this was acceptable using the criteria for comparing analytical results used in conducting confirmatory measurements inspections. The licensee uses the vendor's uncertainty in calculating resolutions, which in turn is used to determine acceptabilit The '

inspector stated that since the licensee purchases NBS traceable standards which are provided with a statement of uncertainty to spike the samples, that this value could be combined in quadrature with other sources of error in preparing the sample, to estimate the overall uncertainty, and therefore require stricter performance by a vendo .1 Reactor and Secondary Coolant Chemistry Surveillance Program l

The inspector reviewed the licensee's program for implementing surveillance requirements germane to reactor and secondary coolant chemistry. Areas reviewed included the following:

,

Technical Specification 3/4.4.8-Dose Equivalent Iodine Gross Activity Average Energy (E-BAR)

Technical Specification 3/4.7.1.4- Gross Activity Dose Equivalent lodine Technical Specification 3/4.4.7 - Chloride, Conductivity Technical Specification 3/4.1 4 - Boron Determination (RWST)

Procedures for complying with these requirements and selected records for 1987 were reviewed. No items of noncompliance were note .2 Effluent Release Program The inspector-reviewed the licensees program for sampling and measurement of radioactive effluents. Technical Specifications 3/4.11.1 and 3/4.11.2 requirements for continuous and batch releases apply for liquid and gaseous wastes, respectively. The licensee conducts liquid waste discharge from the Waste Test Tanks. Gaseous releases from the auxiliary building, ventilation, and gaseous wastes from cover gases ~, air ejector and CVCS are released continuously. Containment purges are conducted in a batch mod The inspector reviewed release permits for liquid and gaseous releases, weekly charcoal and particulate' samples / releases and '

selected one liquid release, and compared two gaseous releases ~.

The licensee generated the dose values using the models and equations of the Radiological Environmental Offsite Dose Calculation Manual (REM 0DCM). The licensee values were found correct. Gaseous releases are summarized by the corporate health physics grou Values generated in March, 1987 were checked:

Date Curies Gamma Air Beta Air Gaseous: 3/26 0.024 1.11E-5 3.18E-5 3/28 0.089 4.1E-5 1.18E-4 (values are in mrem) NRC calcalated values were identica Total Body Organ Liquid: 11/10/87 3.27 2.5E-4 2.6E-3 Licensee 2.51E-4 2.64E-3 NRC ,

These differences were due to roundin No concerns were identified in this are .0 Radiation Monitoring Instrumentation The licensee's Instrumentation and Controls (I&C) group is responsible for this system.

! The inspector reviewed the licensee's program for calibration and l functional testing of the Radiation Monitoring System (RMS). I Requirements of Technical Specifications 3/4.3.3.9 and 3/4.3.3.10 for

liquid and gaseous RMS were reviewed. The inspector conducted a walkdown of plant systems and components, including several radiation monitors:

CHS 69 Reactor Coolant Letdown Monitor RE10A/B Turbine Building Vent Monitor RE22A/B Containment Vent Monitor

RM31-1 Component Cooling Monitor

RMSSR08-1 Steam Generator Blowdown Monitor

DASS0-1 Condensate Polishing Monitor

ARC 21-1 Condensor Air Ejector Monitor The following procedures were reviewed: -

SP3450 H01, Liquid Waste Monitor Calibration SP3450 H11, Liquid Waste Monitor Operability SP3450 L41, Radiation Monitor Source Check SP3449J01 ESF Building-Radiation Monitor Calibration SP3449J11, ESF Building Radiation Monitor Operability ,

SP3449J21. ESF Building Discharge Flow Rate Channel Calibration The inspector reviewed selected records of RMS tests, calibrations, and >

channel checks. Records from July to October, 1987 were reviewed. In addition to monthly source and quarterly analog checks, the calibrations required once per refueling cycle, were reviewed.-

The inspector also reviewed records of performance of surveillances on hydrogen recombiners and monitors pursuant to the requirements in Technical Specification 3/4. Included in this review were '

procedures:

SP3447C01 Hydrogen Monitor Train B System Calibration SP3447C02 Hydrogen Monitor Train "B" Channel Calibration SP3447L01 Hydrogen Recombiner Test and records of tests:

Train "A" Channel Calibration 9/1/87  ;

Train "B" Channel Calibration 10/19/87

Hydrogen Recombiner 01/21/86 Within the scope of this review, no violations or deviations were note .0 Air Cleaning Systems

The operations group is responsible for fulfilling requirements in this area. The inspector reviewed requirements in Technical Specifications 3/4.6.6, 3/4.7.1, 3/4.7.7, 3/4,7.8, 3/4.7.9 and 3/4.9.12 and reviewed pertinent regulatory guides and ANSI standards to whi;h the licensee is committed.

Accumulated run times are recorded on a compute No surveillances were misse Some records were misfiled but successfully foun Within the scope of this review, no violations or deviations were foun . Audits The inspector reviewed audits germane to the liquid and gaseous effluent control program. Audit No. A24001 was conducted on 10/86 by the licensee's Radiological Assessment Branch (RAB) in the corporate offic The audit was found comprehensive and technically complete. The RAB is due to perform an audit of setpoint methodology and program implementation in December, 198 A Technical Specification audit is presently being conducted. Aspects germane to chemistry and the effluents program were reviewed in Augus The inspector received the checklist of the Audit and discussed it and the results with the licensee. No violations were found by the license Quality Control inspections are presently performed in a manner which is driven by activities initiated as work order Thus, routine preventative maintenance, surveillances and tests are exclude Intra-departmental check by supervisors and on-the-job training are relied upon to control activities in the chemistry are The I&C group uses an independent verification of system operability when equipment is restored to service post calibration or testin Within the scope of this review, no violations were note .0 Exit Interview The inspector met with licensee representatives (denoted in Section 1.0) I at the conclusion of the inspection on November 20, 1987.
