? "e No violations or deviations were identified.
5.
Solid Radwaste (IP 84750) I The inspector reviewed the licensee's solid radwaste management program, j including changes to equipment and-procedures; processing, control, and-l storage of-solid wastes; adequacy of required records, reports, and ! notifications; implementation of procedures to properly classify and j characterize waste, prepare manifests, and mark. packages; and experience ~ concerning iden.tification and correction of programmatic weaknesses.
The inspector reviewed selected portions of the licensee's documented i solid radwaste processing, storage, and shipping program for 1989. Also j reviewed was the licensee's compliance with their process control program.
l The licensee generated 736 cubic feet of solid waste in 1989 through
August.
The waste is mainly DAW compacted in 90 cubic foot steel boxes, ! condensate polisher resins dewatered in steel 1.iners, and reactor water , cleanup system resins dewatered in high integrity containers. -Also, the i inspector briefly reviewed the licensee's method of compliance with , 10 CFR 61 requirements. No problems were noted during the inspector's l review except for an incident described in Section 8.
-) ! No violations or deviations were identified other than as discussed in ' Section 8.

i The inspector selectively reviewed portions of the licensee's radwaste shipment records.for 1989 as of September 22, 1989.
The information on . the snippit papers appears to satisfy appropriate NRC, 00T, and burial . site reNi'ements. Shipment classification and manifest preparation is aided by. computer software program (RADMAN).
No problems were noted.
The licensee made five radwaste shipments in 1989 through September 22; one was'a. steel box shipment,.two'were steel' liner shipments', and two were high integrity container shipments. There were no transportation incidents.
No violations or deviations were identified.
7.- Effluent Reports (IP 84750) i The inspector selectively reviewed radiological effluent analysis results to determine accuracy of data reported in the Semiannual Radioactive Radiation Effluent Release Report for the first half of 1989. Technical Specification 6.9.1.11 states that the format and content of these reports shall be in accordance with Regulatory Guide 1.21 (Revision.1) ' dated June 1974.
Section 12.c. of the regulatory guide states that the term "not detected" should not be used.
Instead, a lower limit of detection (LLD) should be reported if the radioactivity in the sample is.below the sensitivity of measurement (for isotopes that have a high probability of being present).
The inspector noted that the licensee reported nondetected probably .present isotopes in liquid and gaseous releases as N/A,'and no references were made to the sensitivities of measurement. This matter was discussed with the' licensee during the inspection and at the exit meeting.
(0 pen Item No. 346/89023-01) No violations were identified.
8.
Effluent Incident-(IP 93702) On September 17, 1989, secondary system chemistry results indicated that backwash of one condensate polishing demineralizer was necessary.
Because there now is primary to secondary leakage, polisher backwash is directed to a condensate polishing demineralizer holdup tank instead of the settling basin (outdoor pond that decants to the lake).
After beirig notified by the chemistry department that a backwash was needed, an operations supervisor assigned an operator to perform the proper valve lineup; the operator was then to contact a chemistry tester.
(technician) to perform the backwash operation. The operator, who had not performed this operation before, did not perform a correct valve lineup; consequently, instead of the backwash being directed to a specific holdup tank, the backwash was directed to the settling basin.
Failure of the operator to follow the procedure was a violation of Technical Specification 6.8.1.a which requires that written procedures be established, implemented, and maintained; no Notice of Violation will
W= b. ;[ :,% f, oc h=' 'be issued because the violation meets the requirements of 10 CFR 2, ' Section V.G.I.
However, the licensee did not write a Licensee Event Report _ (LER) for failure to' perform the Technical Specification 4.11.1.1.1 sampling and-analysis requirements; failure to write the 'LER_ is'a violation of 10 CFR 50.73(a)(2)(1)(B)'(Violation No. 346/89023-03).
J . I N Because there was no intent to backwash the polisher resins to the . settling basin, no samples of the backwash materials were collected and v analyzed..Fai. lure to sample and analyze the condensate demineralizer , contents before release'is a violation of Technical Specification 4.11.1.1.1 (Violation No. 346/89023-02).
, In response to the event, the licensee initiated Potential Condition . Adverse to Quality Report (PCACR) No. 89-0453. The r_eport concludes that procedure DB-CH-0617 " Condensate Polishing Demineralizers -. Backwash Operations," which specifies valve lineups and backwash operations for
both. operations.and. chemistry personnel, was unnecessarily complex and .not s'pecific enough to assure that a proper valve lineup would be I performed. -The licensee revised the procedure by eliminating unnecessary information, designating which steps operators are to perform, simplifying , valve lineup verification lists, and requiring that the procedure be in l ' hand, i i After it was recognized that the resins were inadvertently directed to ' the settling pond, the licensee sampled the setting. basin outfall; no activity was detected. The licensee assumes that most of the resin
remained in.the settling basin.
The licensee estimated that the j ingestion dose commitment to members of the public from the tritium ] content of the backwash liquid was 1.68 E-6 mrem, j
1 The licensee's internal investigation and followup for this-event was j good except for failure to submit an LER. The violations were discussed .) at the exit meeting, j Two violations were identified.
' 9.
Exit Meeting (IP 30703)' The inspector met with licensee representatives (denoted in Section 1) at.the conclusion of the onsite' inspection on October 20, 1989, and by telephone on October.25 and October 31, 1989.
The inspector summarized ! the scope and findings of the inspection. The inspector.also discussed I the likely informational content of the inspection report with regard to - documents and processes reviewed by the inspector during tte inspection.
The licensee did not identify any such documents or processes as
, proprietary.
The following matters were discussed sperifically by the a inspector: ) ) a.
The use of N/A designations on semiannual efflyent reports. The l $"li, licensee stated that they would alter their reporting method to J-those recommended in Regulatory Guide 1.21 (Section 7).
