Licensee Action on Previous Inspection Findings (Closed)
Open Item (78-23-04)
Supplement to Semi-Annual Repor Corrected copies of two pages to January-June, 1978, Semi-Annual Report have been received and reviewe (Details I, paragraph 6.d.) Unresolved Items No new unresolved items were identified during this inspectio.
Radioactive Effluent Releases -
Liquid An inspector discussed processing and release of liquid radwaste with licensee representatives and reviewed the controls applied through the liquid waste release permits (LWRP).
A licensee representative stated that a new liquid waste evaporator was installed about one year ag He said the evaporator is rated at 15 gpm and has performed well thus fa RII Rpt. No. 50-261/78-28 1-2 Based on information provided in the Semi-Annual Reports for the periods July-December, 1977, and January-June, 1978, the release rates of radioactive liquid effluents were well within the limits specified in Technical Specification 3. An inspector reviewed all LWRP's for the 1st Quarter, 1978, and verified that the release rates over that period were well within the technical specification limits. The inspector also verified that where the licensee's more restrictive administrative limits were exceeded, the appropriate review and approvals were obtained prior to release. This review further verified that liquid waste sampling and analysis was done during that period in conformance with the technical specification requirement The routine analyses performed prior to each release consist of tritium, by liquid scintilation counting; gross particulate, by proportional counting of an evaporated sample; and dissolved noble gases, by Nal gamma spectrometr The sum of the particulate and noble gas concentrations is entered on the LWRP as gross beta-gamma concentration, which forms the basis for the daily administrative limit on activity release In reviewing the 1st Quarter, 1978, LWRP's, the inspector found several examples where errors were made in adding the particulate and noble gas concentrations. Also, a few errors were noted in the calculation, for accountability purposes, of activity released based on sample concentration and volume released. Although the net effect of the errors observed did not appear to be significant, the inspector stated that the need for more care and attention to detail by the technicians was indicate The RC&T foreman concurred, and held a meeting with the technicians to emphasize those concern.
Radioactive Effluent Releases - Gaseous An inspector discussed with licensee representatives the sampling and evaluation of gaseous effluents prior to releases and for accountability purposes, and reviewed the application of the gaseous waste release permit (GWRP) to the control of release During these discussions, a licensee representative said that the steam generator blowdown system was modified during the Spring, 1978, refueling outage to install a heat exchanger prior to the flash tan This mode of operation is used for reactor power above 30%,
effectively eliminating gaseous releases from the blowdown syste Prior to this modification, the licensee assumed steam generator blowdown to be released as 30% steam and 70% wate RII Rpt. No. 50-261/78-28 1-3 Based on information provided in the Semi-Annual Reports for the periods July-December, 1977, and January-June, 1978, the release rates of radioactive gaseous effluents were well within the limits specified in Technical Specification 3.9.2. An inspector reviewed all GWRP's for the 2nd Quarter, 1978, and verified that the release rates during that period were well within the technical specification limit The inspector also verified that sampling and analysis of gaseous wastes was performed during that period in conformance with T.S. 3.9.2 and Table 4.1-2, Item 1.
Records and Reports of Radioactive Effluents Based on detailed reviews of waste release permits and weekly summary reports, as well as spot checks of other supporting documentation, the inspector had no questions regarding the adequate maintenance of effluent record The inspector performed a detailed review of the liquid and gaseous effluent data provided in the Semi-Annual Report for the period January-June, 197 This included verification that the summary totals of activity released agreed with the sum of the isotopic activities reported, verification of the average concentration released (liquid) and the average release rate (gaseous),
and verification of the reported percent of applicable limit for the various types of emission The inspector verified that the isotopic activities released, as reported, agreed with the on-site summary data for liquid (1st quarter) and gaseous (2nd quarter) releases. Additional independent checks were made of specific isotopic data in the on-site weekly summary report No significant discrepancies were identified in any of the reported dat In performing a spot check review of daily computer printouts of gaseous activity released from condenser off-gas, the inspector noted an apparent computer error in summing microcuries/hour to get microcuries/da The printouts for June 1, 1978 through June 5, 1978 were checked, and errors were found in the totals for June 2 and June 3. The two errors identified were conservative; that is, the off-gas activity released was over-estimate The inspector stated that a review of past data should be made to determine the scope of the problem and whether any significant errors exist in the reported gaseous activity release Since the plant vent gas activity released is similarly computed, the inspector stated that the review should also include a check of plant vent dat Licensee representatives acknowledged the
RII Rpt. No. 50-261/78-28 1-4 inspector's comments and stated that such a review would be mad (78-28-01) IE Report No. 50-261/78-23 discussed an error in the solid waste shipment section of the January-June, 1978, Semi-Annual Effluent Report (78-23-04). Corrected copies of pages 12 and 14 of that report have been submitted to Region I there are no further questions on that ite.
Procedures for Controlling and Evaluating Effluent Releases An inspector reviewed Health Physics Procedure 14,
"Liquid Release Accountability",
and Health Physics Procedure 15,
"Gaseous Effluent Accountability", taking note of changes and revisions over the past yea All changes and revisions appeared to have been made in accordance with the procedural control system and reviewed and approved by appropriate management. A complete revision to HP-15 was approved in November, 1978, and a similar revision to HP-14 is planned in the near futur The licensee appeared to be complying with the approved procedure The licensee has recognized a need to develop and upgrade written instructions to provide the step-by-step details needed for consistency in the sampling, analysis, approval, documentation, and accountability associated with effluent releases. These are being developed in the form of Health Physics Instructions requiring review and approval by the E&RC Superviso The inspector noted that a considerable effort will be required to get the necessary instructions completed and issue Licensee management acknowledged the inspector's comment, and indicated that emphasis would be placed on the projec The status of these implementing instructions will be reviewed during a later inspection. (78-28-02) Exit Interview The inspector met with management representatives (denoted in paragraph 1)
on December 1, 1978, and summarized the scope and findings of the inspection.
