Licensee Action on IE Bulletins 78-07 and 78-08 IE Bulletin No. 78-07 - Protection Factors for Air Line Respirators and Supplied Air Hoods. Southern California Edison (SCE) Chemical and Radiation Protection personnel reviewed their respiratory protec tion progra No demand mode air line respirators are used in the program. Supplied air hoods are used in two system One system uses a.ir lines from a manifold on the service air compressors. Proper air flow to hoods is provided by maintaining 50 psi pressure in a manifold. The pressure guage on the manifold was calibrated to confirm the accuracy of reading The second system is a self-contained unit that uses a battery powered blower to draw air thru a filter into the hood. Proper air flow, 6 CFM minimum, was confirmed on two of the units by use of a calibrated vane velometer provided by the manufacturer. Proper flow rates of other units were to be verified by measurement before us The SONGS procedure for respiratory protection system use specifies a maximum protection factor of 1,000 for use of these hoods. A written reply to the bulletin had been submitted to NRC R IE Bulletin 78-08 - Radiation Levels from Fuel Element Transfer Tubes. The inspector discussed the requested response actions with the SCE nuclear engineer assigned to the task. He and the Chemical and Radiation Protection Supervisor had discussed the topic and rel viewed plant engineering drawings (569098-2, Reactor Structure, Fuel Transfer Tube). There are no open access points along the SONGS-l Fuel Transfer Tube. Drawings show a minimum of 5' 6" of concrete sur rounding the tube inside containment and 2' of concrete and 11'

of soil between containment and the Fuel Storage poo The Chemical and Rad iation Protection Supervisor plans to conduct a survey of levels at accessible distances along the tube during fuel transfers in the September refueling outag No items of noncompliance or deviations were identifie. Neutron Dosimetry/Monitoring Practices The inspector discussed neutron dosimetry methods and neutron monitoring practices at SONGS-1 and reviewed personnel exposure records for 1977 and part of 197 The licensee presently uses NTA Type film for neutron dosimetr Reported exposures in 1977-78 were infrequent and low. In most instances, the persons with reported neutron doses of 20-30 mRem had job assignments which did not involve access to neutron radia tion. Most, if not all reported exposures in the period examined, were considered to be dosimetry methodology artifacts not related to actual exposur The licensee has used neutron sensitive self-reading dosimeters in the past for containment entries during reactor operation. Presently, a Studsvik "REMETER" type instrument is used for neutron monitoring during infrequent containment sphere entries. Surveys in the past have identified areas of limited access with neutron levels as high as 1,000 mRem/hr and general levels on the operating deck of 20 to 50 mRem/hr. Other levels have been noted, but the gamma radiation level in these areas is known to be high and limits on access is es tablished based on the gamma levels. The licensee is evaluating Harshaw TLD Albedo Type dosimeters for possible neutron monitoring use with their in-house TLD personnel monitoring syste No items of noncompliance or deviations were identifie. Post-Strike Operations in the Chemical-Radiation Protection Area The inspector discussed the impact of post-strike return of bargaining unit employees. On their return to work, all Chemical-Radiation Pro tection technicians worked together for a one or two day phase in period with nonbargaining unit staff, who had been performing analyti cal and monitoring duties during the strike. The technician foremap counselled with returning employees on an individual basis to ident fy and resolve any problems. All Chemical-Radiation Protection techni cians have returned to wor Samples of surveys and gaseous and liquid release reports were examined covering the period of April to August. This included the pre-strike, strike, and post-strike periods. There was no evidence of significnt data reporting errors or omissions in the changeovers between pre strike, strike and post-strike statu No.items of noncompliance or deviations were identifie. Status of Confirmatory Measurements Sample Analysis The inspector discussed the status of the current series of confirmatory measurement samples. The charcoal and particulate samples provided 1y the HSL were received by the licensee and are presently being analyze Resolution of quantitative values for one isotope in the gas sample was not accomplished by the conference between licensee, HSL and NRC representatives. A new gas sample will be taken, analysed and sub mitted at the time of the next inspectio No items of noncompliance or deviations were identifie.

Status of SCE/ff-Site Agency Action Related to Recent Emergency Dril The inspector contacted the lead licensee representative and discussed the status of the followup actions projected following the emergency drill of June 13th. The licensee representative indicated that some off site agencies had corresponded with the licensee relating proposals for improvements in emergency response communication and coordination with SCE. SCE has held an additional in-house review meeting and plans to contact all off-site agencies to set up a mid-September meeting to to discuss and implement improvements that have been suggeste The SCE representative will place the NRC inspector on the mailing list for announcement of the next meetin No items of noncompliance or deviations were identifie. Status of Plans, Training for Refueling Outage The inspector interviewed licensee representatives regarding the status of radiation protection aspects of plans for the refueling outage. Scheduled shutdown is September 15, 1978. Special sessions of the three day Qualified Escort Training and one Day Requalifica tion Training programs are being conducted to assure that the ex pected large influx of contract personnel will be properly escorted and all appropriate SCE Headquarters personnel will be currently qualified for unescorted access during the refuelin Two additional access control stations will be set up to provide quicker identification and personnel dosimetry tabulation and verifi cation for contractor and SCE "non-station" personnel. A computeriied system has been devised to provide essentially real time accumulated dose and restricted area access authority for all persons who are issued a personnel dosimete Protective clothing, respiratory protective equipment and personnel dosimetry supplies have been ordered and accumulated in preparation for the outag No items of noncompliance or deviations were identifie. Review of Reports The inspector reviewed portions of the SONGS-1 Semi-annual Operating Report and Annual Environmental Studies Report. A table summarizing personnel exposures was found to be in error as a result of the typo graphical omission of one dose category. The error was called to the attention of the licensee and noted and corrected on the origina No items of noncompliance or deviations were identifie.

Exit Conference An exit conference was held with SCE staff and management personnel to review the scope and findings of the inspection. The inspector advised licensee representatives that no items of noncompliance were identified.
