DETAILS 1.0 Individuals Contacted

• E. Boulette, Plant Manager 0. Lemieus, I&C Supervisor R. O' Clair, Environmental Service Field Supervisor, Central Maine Power P. Radsky, Chemistry Section Head J. Stevens, Lead Chemist

• 0. Sturniolo, Principle Radiological Engineer

• Denotes those present at the exit interview on September 16, 198 .0 Management Controls The inspector reviewed the licensee's management controls for the radiological environmental monitoring programs (REMP), including assignment of rer.ponsibility, program audits, and annual reports required by the Technical Specification .1 Assignment of Responsibility The inspector reviewed the organization and administration of the REMP. The program is administered by the Principle Radiological Engineer, who has the responsibility for ensuring that federal, state, and corporate requirements are fulfilled, as well as for review of analytical results and reports generated within the p ro g rar.i. Actual day-to-day performance of the REMP requirements is carried out by the Environmental Service Field Supervisor, an employee of Central Maine Power, a part owner of the Maine Yankee Nuclear Power Station. This individual will be employed by Maine Yankee in the near future and will report to the Principle Radiologi-cal Engineer. The principle Radiological Engineer reports through the Manager, Nuclear Engineering and I.icensing, to the Vice President for Quality Program and Engineering (Maine Yankee Atomic Power Company corporate office). The inspector determined that the REMP remains essentially the same as it was at the time of the last inspection in this are l 2.2 Audits The inspector reviewed the following audit reports for the REMP and audits of the contractor laboratory, Yankee Environmental Laboratory I (YEL):

'MY-87-02 "Chemistry, Radiological Effluent Technical Specifications /0DCM, and REMP," October 8, 1987 l

This labo atory participates in the EPA crosscheck program. In addition, approximrtely 25% of the laboratory through put consists of various QC samples: blind duplicates, blanks, replicates, and spike sample The licensee prepares blind duplicate samples and sends them to the YEL for analyses. The results from these blind duplicate samples are used to check for precision in laboratory analyse Analyses of QC data are listed in the annual report. The inspector reviewed these statistical analyses of the data and determined that the YEL performed a good QC program for analytical measurement .0 Implementation of the REMP 4.1 REMD Manual and Procedures The inspector reviewed following procedures: l

• Procedure No. 26.1, "Cffsite Environmental Sample Collection Requirements and Dose Calculation Methods,"

Revision 1. March 30, 1933 Procedure No. 26.301, "Environmental Media Sample Collection Methods,' Revision 2, April 11, 1938 1 l

Procedure 26.301 is designed to provide guidance for using the

"Procedures Manual for the Maine Yankee Offsite Radiological Environmental Surveillance Program." The inspector reviewed the manual. The manual describes sampling procedures for air, milk, l water, soil and ingestion pathway samples such as lobster, crabs and vegetables. The manual also describes the calibration and maintenarce of the air sampling equipment. No problems were j identifie I I

l 4.2 Ofrect Observation The inspector examined selected air sampling stations; all of the examined stations were operating at the time of this inspectio i'

The inspector observed ti,e land use census on September 14, 198 The land use census is required annually by Soction 4.8.B of the Technical Specificotions. The inspector noted that the licensee perft..wed the census as required by the Technical Specificatio No problems were identifie .0 Environmental Dosimetry l

The U. S. Nuclear Fegulatory Commission (NRC) Direct Radiation Monitoring Network is operated by the NRC (Region I) to provide continuous measurement of the ambient radiation levels around nuclear power plants, (71 sites) throughout the Un's, States. Each site is monitored by arranging approximately 30 4 e thermoluminescent dosimeter (TLD)

stations in two concentric r ngs extending to about five miles from the power plan The monitoring esults are published in NUREG-0837 quarterl One of the purposes of this progrsm is to serve as a basis of comparison with similar programs conducted by individual utilities which operate nuclear power plants. In general, several NRC TLDs are collocated with each licensee's TLD stations. During this inspection the monitoring results of the licensee's TLDs collocated with NRC's were compared and the l results are listed in Tabla 1. It should be emphasized that the collocated TLDs are not alwajs situated next to each other, but may be as much as one tenth of a mile apart or more. Although there are some differences betweer, the NRC's and the licensee's results, they are generally in agreemen .0 Meteorological _ Monitoring The I&C Department has responsibilities to perform calibration and preventive maintenance of the meteorological instrumentation. The inspector reviewed the calibration procedure and the current calibration results for wind speed, wind direction, and air temperatur ! Procedure 6-100-2, "Quarterly Calibration of Meteorological System,"

l 1 Revision 3, July 1, 1988 describes all calibration steps including

acceptance criteria. The inspector reviewed calibration results for 1987 i

and 1988 and found all results within the acceptance criteri .0 Exit Interview i

The inspector met with the licensee representatives (identified in ;

Paragraph 1) at the conclusion of the inspection on September 16, 198 The inspector summarized the purpose and scope of the inspection and the inspection finding !
