3.0 Implementation of the Radiological Environmental Monitorirn Ptuytam (REMP)

3.1 Direct Observation he inspector examined selected environmental nonitorirg stations including air samplers for iodines and particulate, TID stations for the roastuuusit of direct radiation (TID stations), and milk ard vegetable sampling locations. All air samplirg equi];rnent at the selected stations was operational at the time of the inspection. All TIDs were placed at the nonitoring stations. Milk ard vegetable samples were available at the identified sampling station .2 Review of Annual Reports he inspector reviewed the Annual Radiological Environmental Reports for 1986, 1987, and 1988. Rese reports provided a comprehensive summary of the results of the RmP around the Yankee Rowe site, and met the Technical Specification reportiry recitirements. Exceptions to the program, such as missing data, were noted and explained. The irdpr also reviewed the available 1989 analytical data for the RmP. No violations were identifie .3 Procedures m e inspector reviewed the following procedures to determine the implementation of the Rm o CP-4952, Rev.16, " Radiological EnvitunmenLal Samplirg" o OP-4971, Rev. 2, " Environmental Composite Sampler Operability" o OP-6606, Rev. 6, "'Ibtalizing Gas Flow Meter Calibration Check" o DP-9730, Rev.1, " Preparing ard Retrieving Envirumsstal TID's for Field Application" h e inspector also reviewed the calibration results for the air sampler and noted all the calibration results were within the licensee's defined acceptance criteria.

'Ibe inspector reviewed the quality control analytical results for 1988 perforned by the contractor laboratory and fcund these results were within the licensee's defined acceptance criteria. We inspcetor also noted that the licensee corriucted investigations of anomalous QC results and resolved those result .0 Environmental Dosinntry Fivytcuu 4.1 Dosimetry System The inspector noted that the Yankee EnvirumuAal laboratory (E-lab) was assigned the responsibility to roasure direct radiation levels using the Panasonic 'Ihermoluminescense Dosimetry (TID) System in 1987. 'Ihe licensee had used the Teledyne TID System prior to the Panasonic TLD Syste The licensee monitored direct radiation levels usirg both TLD systems and evaluated the monitoring results before charging to the Panasonic TID System. 'Ihe E-lab performed a study to deucroLtate compliance with Regulatory Guide 4.13 (Performance, Testing, arri Procedural Specifications for 'Ihernoluminescence Dosimetry (TID): Environmental Application). We inspector reviewed these test results during this 5spection and fourxl them satisfactory. 'Ihe inspector had no further questions in this are .2 Enviiviumntal Dosimetry

'Ihe U.S. Nuclear Regulatory rw-nhion (NRC) Direct Radiation Monitoring Network is operated by the NRC Region I to provide continuous measutusents of the ambient radiation levels around nuclear power plants, throughout the United States (72 sites). Each site is nonitored by arrangirg about 30 to 50 TID stations in two concentric rirgs extending to about five miles from the power plant. 'Ihe monitoring results are published quarterly in IUREG-083 One of the purposes of this program is to serve as a basis of comparison with similar programs corriucted by individual utilities which operate nuclear power plants. Duriry this inspection the nonitoring results of the licensee's TIDs collocated with IRC's were coq. ured and the results are listed in Table 1. Although there were some differences between the NRC's and the licensee's results, they were generally in agreemen .0 Meteorological Monitoring he inspector reviewed meteorological instrumentation calibration results for 1988 arrl 1989 for wind speed, wind direction, and temperature. 'Ihe licensee uscx1 a contractor to perform the calibration of meteorological equipment quarterly usirg the procedure, "OP-4150, Vendor Calibration an.Vor Maintenance of the Meteorological Data Gathering System Instrumentation".

the meteorological tower to the recorders i the control room to compensate any line los(chart recorder noted s. The inspector and computer) in '

.that the wind speed and temperature calibration results were out of '

tolerance specified in the above procedure several times due to the chart i recorder drift. The licensee suspected that the sensitivity of the chart !

recorder was not adequate to differentiate small changes. The licensee, however, did not have any calibration problems with the computer output-data and these computer data were the primary data to implement the REM The inspector determined that all calibration results were within the acceptance criteria after readjusting the chart recorde The licensee-calibrated the meteorological monitoring equipment more frequently (quarterly) than required by the Technical Specifications (semiannually).

6.0 Exit Interview The inspector met with the licensee representatives denoted in Paragraph 1.0 at the conclusion of the inspection on July 7,1989. The inspector summarized the purpose and scope of the inspection and discussed the result __ . _ . _
