President, Nuclear and Environmental _ Engineering.
Laboratory oversight, review and analysis of data, and i
i preparation _of the annual radiological environmental monitoring program report are the responsibility of engineers in the Radiological Assessment Branch (RAB).
The Manager, RAB, reports through_the Director of the Nuclear Engineering Department to the Vice President,
,
tuclear and Environmental Engineering. The inspec'or determined that the licensee met the criteria for an independent audit.
The inspector reviewed the following procedures and audits:
NE0 2.02; Nuclear Engineering and Operations Procedure Charter for Nuclear Review Boards, Rev. 3.
May 2, 1988 NE0 3.01; Nuclear Engineering and Operations Procedure Conduct and Format of Nuclear Review Board Audits.
Rev. 3. March 28, 1988

NRB Audit A25002, May 1986 NRB Audit A25019, December 1987 Based on a review of the NRB Audits, the inspector noted that the licensee followed appropriate procedures including requirements, findings, resolutions, root causes, and corrective actions. The inspector determined that the above referenced audits were very thorough and followups were excellent.
The audits were performed by a qualified lead auditor, and appeared to be quite thorough and of
,
sufficient technical depth to adequately assess
'
performance of the REMP.
3.2.2 Audit of Contractor Facilities The audits of contractor laboratories (Teledyne and Clean Harbors of Natick) is performed in accordance with the procedure RAB 1-4, "Radiological Environmental Monitoring Audit Program." The inspector reviewed several 1986 and 1987 audits of contractor facilities and determined that they were being per'ormed in accordance with the above-procedure and that findings were being followed and adequately resolved.
3.2.3 Internal Audit The Environmental Audits Group (Environmental Programs),
independent from the Quality Services Departnient, conducts internal audits for the meteorological s3.tems at the t

.
Production Operation Services Laboratory (POSL),_in accordance with EPD 6.02, Environmental Programs Department Procedures, Annual Meteorological System Audit, Rev. 2, March 1987.
The inspector reviewed 1987 audit results and determined that the audits were performed as required by the above procedures.
3.3 Quality Assurance The licensee described the methods used by its contractor laboratories, Teledyne Isotopes and Clean Harbors of Natick, to assure the accuracy of its analytical measurements.
These include participation in the EPA crosscheck program, an intralaboratory program for analysis of spiked, split, and blank samples, and a program for analysis of duplicate and replicate samples from various locations and sample media within the REMP.
The inspector reviewed selected quality control data submitted to the licensee by its contractor.
These data indicate that the contractor's re*ults are for the most part in agreement with the EPA values and that its intralaboratory results are normally in agreement with the actual values.
For those instances in which the results did not agree, reasons for the differences were investigated and the discrepancies were resolved. Generally good agreement was noted among the licensee's duplicate and replicate samples.
4.0 Implementation of the Radiological Environmental Monitoring Program The inspector reviewed the licensee's commitments pertaining to its operational radiological environmental monitoring program, by discussions with the licensee, by review of reports, and by direct observation.
The inspector concluded that an effective program is in place, and that it conforms to the licensee's Technical Specifications.
,
The inspector examined selected environmental monitoring stations including air samplers for iodines and pai ticulates and TLDs for direct raatation measurement. All equipment at these stations was operational at the time of the inspection. The inspector reviewed procedures and records for calibration and maintenance of the air samplers and vacuum
.
gauges, and found that these calibrations were performed regularly and on schedule.
The inspector reviewed the 1985, 1986 and 1987 Annual Radiological Environmental Operating Reports regarding sample media, sampling j
frequencies, sampling stations, and analytical results.
The inspector
{
determined that these were complete and comprehensive summaries of
'
sampling, analyses, and results of the REMP, including various aspects of quality control.

5.'0 Environmental Dosimetry The U.S. Nuclear Regulatory Commission (NRC) Direct Radiation Monitoring Network is operated by the NRC (Region I) to provide continuous measurements of the ambient radiation levels around nuclear power plants (71 sites) throughout the United States.
Each site is monitored by arranging approximately 30 to 50 thermoluminescent dosimeter (TLD)
stations in twc concentric rings extending to about five miles from the power plant.
The monitoring results are published in NUREG-0837 quarterly.
One of the purposes of this program is to serve as a basis of comparison with similar programs conducted by individual utilities which operate nuclear power plants.
Therefore, four NRC TL0s are collocated with each licensee's TLD stations.
The licensee monitors the environmental radiation levels monthly (2 TLDs each station) using EG&G TLDs (Model TL-34, CaF2:Mn) and Victoreen TLD readers (Model 2800 and 2810). During this inspection the monitoring results of collocated TLDs were compared and the results are listed in Table 1.
Although there are some differences between the NRC and licensee's programs, such as monitoring period, starting date of quarter, and monitortag height, results are generally in good agreement. The inspector noted that the licensee did not report a standard deviation in the annual reports. However, the licensee calculates the mean and a standard deviation in separate note'oooks.
The licensee stated that standard deviations will be included in the future.
The Environmental Dosimetry Program is being performed by the POSL. The inspector reviewed the following procedures:
ES#141; Thermoluminescent Dosimeter Readout, Rev. 10, April 1986, ES#142; Thermoluminescent Oosimeter Calibration, Rev. 5, March 1988, ES#143; TLD Self Irradiation Determination, Rev. 5, July 1987.
Through review of the above procedures and calibration results, the inspector noted that the lice.nsee did not complete the TLD fading study.
The inspector recommended to complete the study and apply the corrections if there are any differences.
The licensee participates in the International Environmental Dosimeter Intercomparisons Program.
The inspector reviewed the results of the sixth (1982), seventh (1984), and eight (1986) intercomparisons. All results, known field and laboratory exposures, were in good agreement.

6.0 -Meteorological Monitoring The POSL has responsibility for the maintenance and calibration of the
'
meteorological monitoring system.
Calibrations of the system are performed quarterly.
The inspector reviewed the following procedures and calibration results:
ES#201; Wind Direction System Calibration, ES*202; Dew Point System Calibration, ES#203; Temperature / Delta Temperature System Calibration, ES#205; Wind Speed System Calibration ES#206; Analog Recorder Calibration ES#211; MET Tower Equipment Surveillance ES#214; Meteorological Tower Inspection ESt403; Meteorological Tower Preventative Maintenance Calibration Results; June 1987, November 1987, January 1988 Within the scope of the above review, the inspector noted that calibrations were performed as scheduled and results were within the tolerance values.
The inspector reviewed all meteorological parameters (temperature / delta temperature, wind speed, and wind direction at 33 feet and 196 feet levels) at two termina'is; meteorological tower station and the control room.
The inspector found there was no disagreement between the two terminals.
7.0 Exit Interview The inspector met with licensee represe.satives denoted in Paragraph 1 at the conclusion of the inspection on May 15, 1988 at the Haddam Neck Plant
,
and on May 27, 1988 at the NUSCO.
The inspector summarized the purpose and scope of the inspection and discussed the inspection results.
