-

several gross alpha sensitivities, sample backlog problems at the Environmental Radiological Laboratory due to a shortage of trained personnel resulting in excessive count times for Sr-89 analyses, and variation in the temperature and humidity in the laboratory possibly causing instrument abnormalities during the period from January through December 1983. The inspectors reviewed the licensee's response to the violation and the corrective actions taken to avoid further noncomplianc The licensee implemented a program to ensure adequate sample volumes are collected and that samples are shipped promptly to the laborator Additionally, ,

appropriate environmental limits for radioanalytical instrument operations I were defined and an engineering evaluation was made to determine the necessa y ventilation modifications. Additional staffing positions for the Environmental Radiological Laboratory were approved and partially fille An evaluation of the analysis procedures for water samples with large quantities of solids present was conducted to provide guidance on the actions taken when that type of sample was encountere This item is considered close . Employee Concerns, Discussions and Findings Concerns The following employee concerns were identified: (1) adequate temperature control could not be maintained in the Environmental Radiological Laboratory (ERL); (2) the Body Burden System at the ERL was experiencing problems and was out of service since November 1984; and (3) the Environmental Radiological Laboratory was understaffed and lab technicians were inexperienced in the environmental monitoring area and in evaluating nuclear dat Discussion The employee concerns were based on an approximately 21/2 year time period. During this time period the employee noted reluctance on the part of supervision to act in a timely manner to correct problems identified in the laboratory even though these problems were brought to supervision's attention. The inspector interviewed laboratory personnel and determined that temperature and humidity controls in the laboratory were not adequate in that temperature differentials of ten degrees were typical. As an interim fix, the licensee installed an automatic condenser by pass on the facility (verified by letter dated April 1, 1985). As a permanent fix, the licensee had drafted plans to upgrade the entire ventilation system. At the time of this inspection, environmental conditions in the laboratory were adequat The inspector determined that the Body Burden System was experiencing problems during the latter part of 1984 and had been out of service intermittently since that tim The Body Burden System was out of service at the time of this inspection. The Body Burden System at the

- . .

.

.

ERL was used mainly for General Office personnel and as a backup to the McGuire Nuclear Station. The inspector noted that the Body Burden System at the McGuire Nuclear Station was operabl Through _ interviews with licensee personnel, the inspector determined that the Environmental Radiological Laboratory was understaffed which resulted in sample backlogging problems and an NRC violation for failure to meet required analytical sensitivities for a total of 42 samples during the period January through December 1983 (50-269/84-19-02, 50-270/84-18-02, and 50-287/84-20-02). The licensee's response to the violation indicated that some of the sensitivities were not met due to both environmental conditions in the laboratory possibly causing instrument abnormalities and a shortage of trained personnel due to personnel turnover resulting in a sample backlog which made some normal counting durations unacceptably long. During this inspection, the ERL was comprised of a Junior Health Physicist, who was the Laboratory Coordinator, and two Health Physics Specialists, all qualified to work in the radioanalytical lab. Additionally, there were three technicians in training who were hired during 1984. The licensee stated that the Environmental Radiological Laboratory was budgeted for two more positions in 198 The licensee recently developed a comprehensive training and qualifications program described in the Radiological Health Physics Procedures Manual, Section 4.0 " Radiological Health Training and Qualification Program." The program was developed so that inexperienced techr.icians would become qualified to work independently in the radioanalytical lab. The licensee stated that the ERL staff was

'

working overtime to meet the environmental sampling and analysis requirements described in the plant-specific technical specification Finding The employee concerns regarding inadequate temperature control in the ERL, electronic problems with the ERL's Body Burden System, and

.

staffing problems at the Environmental Radiological Laboratory were all ( substantiated. Corrective actions are being implemented to alleviate j the employee's concerns.

! Audits and Appraisals (807,21)

i Technical Specification 6.5.2.9 required audits of station activities to be

'

performed under the cognizance of the Nuclear Safety Review Board (NSRB),

including the Radiological Environmental Monitoring Program and the results thereof at least once per twelve months. The inspectors reviewed selected

developed a radiological health training and qualification program in response to an audit finding in PS-84-2(PS). The inspectors also noted that the licensee developed a program to inventory the various radiological sources in the laboratory in response to an audit finding in PS-85-1(PS).

Additionally, the inspector reviewed an ERL audit conducted by the System

'

Health Physics Unit of Nuclear Technical Services conducted February 19 -

20, 1985 (File: GS-750.05, 778.00, March 28, 1985). This comprehensive

-

audit was more accurately described as a " program assessment" of the Environmental Radiological Laboratory. The assessment covered a broad range of activities including staffing, personnel communications, communications between the ERL and the nuclear stations, laboratory QC, and calibration The licensee stated that this was the first assessment of this type performed and that future assessments would be incorporated into the annual QA audit program. The inspectors noted that incorporation of this kind of assessment into the QA audit program would enhance the quality of the audit and improve the overall program. The ERL staff had prepared responses to the assessment findings and were tracking the items in a similar manner to

The inspectors noted that ER/0/B/2300/01 Step 4. stated that water samples were to be mixed thoroughly to distribute solids for gamma analysis. The procedure did not take into account the changes in counting geometry due to solids settlin Licensee representatives agreed to evaluate this area. ' The inspectors noted that the procedures did not adequately describe a formal means to review anomalous data with provisions for timely and appropriate followup. The licensee informed the inspectors that procedures were being developed to cover this area. These items will be reviewed during future inspections (50-369/85-19-01 and 50-370/85-20-01).

Within the areas examined no violations or deviations were identifie . Records, Reports, and Evaluations (80721) The inspectors reviewed selected portions of the following records:

Detector B showed a positive trend for the same time period. Although both trends were within the two-sigma limit, no mention of either trend was made in the Equipment History Logbook indicating the data was not being reviewed thoroughl Licensee representatives agreed to evaluate this area, Technical Specification 6.9.1.6 requires an Annual Radiological Environmental Operating Report covering operation of the unit during the previous calendar year to be submitted prior to May 1 of each yea The inspectors reviewed the McGuire Nuclear Station Annual Radiological Environmental Monitoring Program Operating Reports for January 1, -

December 31, 1983 and January 1 - December 31, 1984. The' inspectors reviewed the reports for omissions, obvious mistakes, anomalous measurements, observed biases, and trends in the data. The inspectors ;

noted in the 1984 Annual Radiological Environmental Operating Report that prior to April 1984, air filter and cartridge samples were counted as a composite as opposed to being counted separately. The licensee had identified' this problem and subsequent to April 3,1984, the air i filter and cartridge samples were counted separately. The inspectors also noted that the licensee identified the need to perform weekly gross beta analyses on air filters in response to an interpretation of Technical Specification 3.1 These analyses began on September 1, 19f4. The _1984 Radiological Environmental Monitoring Operating Report

l l

also indicated that I-131 analyses for drinking water composites and surface water composites during October 1984 did not meet the lower limit of detection (LLD) specifications. As required by Technical Specifications 4.12.1, Table 4.12.1 and 6.9.1.6, the licensee identified and described the reasons for not meeting the LLD The licensee purchased two additional alpha / beta counters in 1984 to avoid future incidences of missed LLDs due to sample backlog. This area will be reviewed during future inspections.

8. Implementation Of The Radiological Environmental And Meteorological Monitoring Programs (80721)

The inspectors conducted a detailed review of the radiological environmental monitoring and surveillance program to determine if the status of the program was consistent with sampling, analytical requirements, and schedules defined in Table 3.12-1 of the Environmental Technical Specifications. The Inspection included the following: (1) review and discussion of monitoring, surveillance, and radiological procedures; (2) review of selected sampling and analytical logs; (3) examination of all air particulate and radioiodine monitoring stations; (4) examination of selected area TLD stations (5) examination of a dairy farm for milk sampling; (6) examination of a continuous surface water sampler and a ground water sampling station, and (7) examination of a shoreline sediment sampling station and two vegetation sampling sites. The inspection disclosed that the radiological environ-mental monitoring and surveillance program was implemented in accordance with Environmental Technical Specification requirement The inspectors verified by direct observation and by record review that the meteorological monitoring instrumentation channels required by Technical Specification 3.3.3.4 were operable and maintained. The inspectors reviewed the meteorological monitoring instrumentation channel calibration records for the wind speed, wind direction, and air temperature- Delta T sensor The inspectors verified that the sensors were calibrated semiannually during 1984 and the first half of 1985 as required by Table 4.3-5 in the technical specifications. The inspector verified that the meteorological readouts in the control room were functioning properl The licensee used strip chart records to record wind speed, wind direction, and air temperature - Delta Meteorological data in the control room were also obtained by means of computer readout. The licensee performed weekly functional checks of the meteorological instrumentation channels by means of a voice relay between the control room and meteorological towe Within the areas examined, no violations or deviations were identified.

9. Facilities, Equipment and Supplies (80721)

The inspectors toured the Environmental Radiological laboratory facilities and noted an orderly laboratory with adequate cleanlines Space and configuration of the wet chemistry laboratory and the counting room allowed for efficient processing and analyzing of environmental sample _

. .

The inspectors noted recent additions to the laboratory counting room equipment. In 1984, two Tennelec proportional counters and one additional Ge(L1) gamma detector were acquire Additionally, the ERL Staff was increased by hiring three entry-level technician It was noted that two positions were still ope Licensee representatives indicated that the additional equipment and personnel should alleviate previous sample backlog problem Within the areas inspected, no violations or deviations were identifie . Quality Assurance Program (80721)

The inspectors reviewed the licensee's quality assurance program for the Duke Power Company's Environmental Radiological Laboratory which was the corporate laboratory supporting the operational radiological environmental monitoring programs at the licensee's Catawba, McGuire, and Oconee facili-ties. The inspectors used the guidance contained in Regulatory Guide 4.15 (Quality Assurance for Radiological Monitoring Programs (Normal Operations)

- Effluent Streams and the Environment - February 1979) to evaluate the licensee's progra The licensee's organizational structure as it related to the management and operation of the monitoring programs, including quality assurance policy and functions, was defined. The duties responsibilities, and authorities of the positions within the organization were described in the Radiological Health Procedures Manual. Responsibilities for initiating, writing, reviewing, and approving procedures were also described in the Radiological Health Procedures Manual. The inspectors noted that the licensee was developing a procedure for the review and evaluation of environmental monitoring data and report The qualifications of individuals involved in radiological monitoring and analysis activities were specified and documented. The indoctrination and orientation program for new technicians was described in the Radiological Health Procedures Manual Section 4.0. Laboratory technicians and analysts were qualified for selected radiochemical and analytical procedures after a formalized training check-off list was completed. Although presently the licensee does not have a formal requalification program, licensee representa-tives agreed that each qualified technician should participate in the EPA cross check program to maintain laboratory analytical skill The licensee had the ability to track and control various environmental samples by maintaining records for field collection of samples, radio-activity measurements of samples, and instrument backgroun Quality control records for laboratory counting systems included the results from measurements of radioactive check sources, calibration sources, backgrounds, and blanks. Daily QC logs were maintained and kept next to the appropriate laboratory counting systems. The inspectors noted that records were well organized and easily accessibl ~

c

.. .

The inspectors reviewed the Environmental Radiological Laboratory's procedures for environmental sample collection. In addition to sample analysis, laboratory personnel were responsible for McGuire Nuclear Station sample collection activitie The procedures specified sample types, sampling frequency, method of sample collection, and sample analyse The inspectors noted the Environmental Radiological laboratory quality control program included the use of NBS traceable reference standards to determine counting efficiencies for specific radionuclides and to determine counting efficiency as a function of gamma-ray energy for gamma-ray spectrometry systems. The licensee also conducted daily performance checks of laboratory counting system and the results of these measurements were recorded in a log and plotted on a control chart. The inspectors also noted that the licensee's QC program was involved with interlaboratory crosscheck analyses. The interlaboratory program included participation in EPA's Environmental Radioactivity Laboratory Intercomparison Program and the licensee' in-house intercomparison progra . Inspector Followup Item (92701)

(Closed) 50-413/84-21-01 and 50-414/84-13-01, Qualification Records of Laboratory Personnel. This item pertained to the inspection finding that qualification records for laboratory personnel were inadequate and that some qualification records were not available. The inspectors noted that the licensee had developed a radiological health training and qualifications program which included the completion of formalized training check-off lists as a technician became qualified to perform a particular radioanalytical procedure. The inspectors reviewed individual training and qualification records of selected laboratory personnel and determined that the records were complete and in order. This item is considered closed.
