Operations-General Spent Fuel Shipment In the period during which the inspection was conducted the plant was in the normal operating mode at full power (-450 MW) until Thursday March 6th when the rupture disc of the Pressurizer Relief Tank. (PRT) was accidently blown out during a tank purging operatio The facility was taken to hot shutdown for twelve to fifteen hours to replace the rupture disc and return the PRT to operable statu This event was reported to Region V by the resident inspector who would follow up on the ite Spent Fuel movement and shipment operations were under way during the inspection. Loaded fuel cask decontamination, AT testing, and licensee radiation monitoring surveys were observed by the inspecto The radiation monitoring operations were discussed with radiation protection personnel and fuel shipment procedures were examined. A survey of radiation levels around the loaded shipping cask was made and levels noted confirmed those reported by the license No items of noncompliance or deviations were identifie. Radioactive Waste Systems - Quality Assurance and Confirmatory Measurements Quality Control The licensee's program for quality control of analytical measurements has not undergone any major change in the past two years. Laboratory procedures are reviewed internally under the standard SCE review and revision program. Small revisions and changes have been made in laboratory procedures in response to changes in published standard chemical procedures and changes announced in-ASTM publication IE Circular 79-21 regarding prevention of unplanned releases of radioactivity. The circular was received, routed to the appropriate section and assigned to an engineer for evaluation. An extensive program of reviews and functional tests of systems handling radio active liquids has been started but other items of higher priority related to TMI lessons learned programs have delayed completion of the preventive measures suggested in the circular. Licensee activity in response to this circular will be checked in a future inspectio This item remains ope (#lC-79-21)
IE Bulletin 80-03 regarding loss of charcoal from certain tray type adsorber cells. The bulletin was received and routed to the appro priate section for review. The.reviewing engineer investigated and determined that the existing charcoal adsorber cell in use at
-
SONGS-1 was not the type described in the bulletin. The cell in use was examined and previous in-place test results were reviewe The licensees report to NRC for this bulletin had been drafted and was in the internal review process at the time of this inspectio This item is considered close No items of noncompliance or deviations were identifie. Licensee Event Report #80-05 Temperature Gradient in Excess of T. S. Limits The temperature gradient across the condenser in the circulating water system exceeded the environmental technical specifications for a short period on February 18, 1980. Preliminary information regarding this matter was transmitted to NRC Region V on February 19, 1980 and a formal, more detailed licensee event report was submitted on February 29, 1980. The inspector discussed the event, its causes and the licensee'scorrective action with the supervisor of plant operations. The circumstances surrounding the event were described as reported, and based on the supervisors' account, the licensee's immediate and followup corrective action was proper and should prevent reoccurrenc This item is considered closed (#80-05 TO).
No items of noncompliance or deviations were identifie. Other Items The inspector attended the licensee safety meeting covering radiation protection practices. Basic principles of radiation protection, concepts of radiation dose and terminology, radiation area designation and posting, and applied practices of contamination and exposure control were presented. This presentation is used for annual requalification of Qualified Escorts of SONGS-The licensees Quality Assurance Program is not directed toward specific laboratory procedures. Quality Assurance audits of laboratory operations are conducted to assure compliance with technical specification requirements and audits of SCE contractor's operations in the area of environmental monitoring and analysis are conducte Radiometric analytical equipment is checked weekly with NBS traceable standard sources for energy and efficiency stability. Annual checks of the energy resolution of Geli detectors are made using standard methods and an NBS Cesium-137 source. The licensee possesses two operating Geli gamma-spectrometric systems and cross checks are frequently made with the same source The.Chemical and Radiation Protection Supervisor and the C&RP technician foreman both review the reports of laboratory results of routine samples. Samples which gives unusual or unexpected results are usually resampled and back-up samples are analysed to identify erratic results or to confirm anamolie Confirmatory Measurements The inspector met with licensee representatives who are responsible for review of radioanalytical methods and for the computer manipulation of analytical data. Analytical results of previously submitted confirmatory measurement samples were reviewed and comparative methods were examined to identify problem areas. The problem areas identified included typographical errors in reports, misreading of efficiency curve data for one hand calculated report and differences in length of counting times between the licensee and NRC contract laboratories for gamma spectrum measurements (with possible ramifications in reporting isotopes in low concentrations and reporting results at high confidence levels). Where possible, differences between NRC and licensee results were resolve A liquid waste tank sample was collected, treated, split and a pre liminary analysis was made at the licensee's facilities prior to shipment to the NRC contract laboratory. A charcoal cartridge and a particulate filter with a mix of isotopes were provided to the licensee for analysis. The results from these samples will be submitted during the week of March 10 to 14, 1980 for comparison with the known activities on the sample No items of noncompliance or deviations were identifie. Licensee Response to IE Circulars and Bulletins IE Circular 79-15 regarding failure of some components in MSA Self Contained Breathing Apparatus (SCBA), SurvivAir I. The licensee received the circular in a timely manner and it was reviewed by an SCE engineer who determined that the type SCBA referenced in the circular was the high pressure type not the type possessed by SONGS-1 for emergency breathing air supply. This item is close The inspector attended a videotape showing the licensee's security orientation program for qualification and granting access into secured area These meetings were attended to maintain qualification for access to radiation protection and security controlled areas on sit. Exit Interview The inspector conducted an exit interview with licensee representatives at the close of the inspection. The elements of the inspection that were completed were reviewed and discusse No items of noncompliance or deviations were identified in the areas examined.
