identified:the failure to include certain monitoring information in 1 individual personnel monitoring files. -It was established that at the time of the inspection individual personnel monitoring. files in the custody of Corporate Documentation Management (CDM) were being microfilmed. Records received by CDM after the start of the microfilming procedure were stockpiled at CDM for later inclusion in the individual-file .

.- 2 The licensee's methods for recording and documenting personnel exposures were reviewed. The dosimetry records system is fully computerize Individual exposures are input to the computer on an on line basis for pocket ionization chamber (PIC) measurements from terminals in Units 1 and 2/3 as workers leave the access controlled area. TLD exposure data is input on a batch basis. Quarterly a~ report, SCE-SONGS Personnel Dosimetry Monitoring Control Report is generated listing personnel exceeding the maximum and 25 percent of the maximum administrative exposure limits. This quarterly report is used to demonstrate compliance with 10 CFR 20.101. The computer data base is backed up daily on tap In addition, a streaming backup (forward recovery system) when combined with the daily tape backup permits recreation of the disc record in the event of a disc crash. Annual records are transferred to tape at the end of the year and stored in a Halon protected vault. Individual records are documented on microfiches in the form of the licensee's equivalent of NRC Form Current individual records are immediately available on the system terminal The computer program requires validation of exposures when PIC and TLD measured exposures differ by 25 percent for exposures;t100 mre The computer system uses two programs SRC and TSO. SRC (SONGS Radiation Control) contains the current records data base, this program which is under the control of the Corporate Computer Group had been rigorously tested to ANSI standard TSO, the archive records system, used to generate quarterly and annual reports, is not a tested program but u ea the SRC data base. The password protected TSO programming can be changed only by the Dosimetry

Supervisor or his singic delegat Personnel Dosimetry Monitoring Control Reports for 1984 and first quarter 1985 were examined. A total of 109 individuals exceeded 25 percent of the maximum quarterly limit with a high whole body exposure of 1957 mre No individual had exceeded 25 percent of the quarterly limit during the first quarter of 198 Termination letters are' computer generated. Undeliverable letters are retained in the individunis fil Procedures reviewed as a part of the inspection:

employed under circumstances where personnel monitoring is required. The

' inspector had no.further questions with respect to.this matte U-(Closed) Followup (50-361/85-09-06) Inspection Report No. 50-361/85-09 identified two observations regarding apparent radiological posting-deficienciesiin the Units 2/3 protected area. Followup inspection with respect'to these matters established the followin *

L Radioactive Materials Storage Area MaterialLremoved from th'e Units 2/3 contro11'ed access area i surveyed and smear tested prior to' release. Prior to uncontrolled release.all' items are moved to a low background laydown area

' adjacent to the Unit 2. makeup water demineralizer for a final

- survey. .All items found t'o'be. contaminated are logged and the maximum count rate measured.with a calibrated GM survey instrument is recor'ded. During first quarter 1985 approximately 150 such items

~

representing a tocal activity of approximately six microcuries were identified. Title 10 CFR 20.203(e) requires posting as a radioactive materials area, locations where more than 10 times an Appendix C quantity of radioactive materials are stored. Based on'

an examination of records,'the lay down area did not contain in om excess of 10 times an Appendix C quantity at any time during the

first quarter of '198
b '. Contamination /High Airborne Area
On March 2, 1985, it was observed that the posting associated with the vent wier structure'was obscured. Discussions with licensee

<

- personnel established.that the vent wier structure is subject,to-routine surveys and air' sampling at times when liquid radioactive

'

<

. waste'is being discharged.. The surveys and' air sampling have never .

resulted in the identification of surface or airborne ' contaminatio Discussions with licensee representative' established that-in both cases identified above, posting had been inconsistent with the-licensees procedures. Prompt-corrective action had been taken to

'

correct the deficiencie In addition, the, licensee established a routine. surveillance program with specifically assigned responsible individuals, to assure.that postings are maintained consistent with-NRC and procedural requirements. In both cases.the licensee's postings were more, conservative than that required by 10 CFR-20, which would ~notihave required that either area be posted. This-s matter;is considered close i Review of Licensee Reports r The inspector reviewed Licensee Event Reports -(IIR) related to radiation protection, chemistry and waste management matters for all units. The

. inspector verified that reporting requirements were met, causes identified or under investigation, that corrective actions appeared Lappropriate and that LER forms were complete.

1 Semiannual Effluent Report Evaluation High Unit- 3 primary system activity and the licensee's decision not to

< recycle water reclaimed from the liquid waste processing system (see Inspection Report.No. 50-206/85-03, 50-361/85-02 and 50-362/85-02 report section 2) had resulted in significant liquid releases. ;The releases reported in Semiannual Effluent Reports for 1984 were compared with projected releases contained in Units 2/3 FSAR Tables 11.3-9,' gaseous effluents and 11.2-38, liquid effluents.

The licensee had established a task force whose goal was the reduction of radioactive material contained in liquid effluents (Inspection Report No /85-03, 50-361/85-02 and 50-36.2/85-02 section 2). This matter was addressed during the exit intervie No violations or deviations were identifie . Unapproved Burial of High Integrity Container (HIC)

On March 20, 1985, the licensee shipped (shipment No. II-SW-85-1) a NUPAC EA-190 HIC containing 112.127 curies as LSA for burial at the Ecology, Richland, Washington, low-level radioactive waste disposal facility. A confirmation of receipt dated March 25, 1985, was received from U.S. Ecology, which noted no discrepancies between wastes listed on the manifest and the waste materials receive On March 26, 1985, the Radioactive Materials Control (RMC) Supervisor at SONGS received a telephone call from the Department of Social and Health Services, State of Washington. The RMC Supervisor was informed that the HIC had been received at U.S. Ecology, inspected by the state inspector, and found to be in order, then buried. The State representative stated that although a letter from the Head of Radiation Control Section,

' Department of Social and Health Services to NUPAC had authorized SONGS to use two EA-190 HICs, that use was contingent on (1) successful completion of drop and pressure tests, (2) approval of the tests by the State of Washington and (3) issuance of a formal written approval of the HIC by the State of Washington. He stated further that although the test data on NUPAC HIC's EA-50, EA-142 and EA-190 had been received and written approval issued for the EA-50 and EA-142 HICs, the EA-190 had not received written approva The RMC Supervisor contacted NUPAC and the RMC Shipping Broker and obtained the following informatio Since this was the first HIC used by SONGS, the RMC Shipping Broker had maintained regular contact with NUPAC prior to shipment. On the day before the shipment NUPAC informed SONGS that no problems existed and that if any developed NUPAC would contact SONGS before the shipment departed. The shipment was made as scheduled in the belief that all requirements had been satisfied. On March 25, 1985, SONGS contact at NUPAC learned that the.necessary approval for the

. HIC had not been issued. NUPAC then telephoned the Department of Social and Health Services and notified them that the HIC EA-190 shipment had been made. The state representatives reportedly assured NUPAC that the necessary letter approving the EA-190 HIC would be issued that day and that there would be no problem in burying the HI (Inspectors note: If
