_ _ _ NRC HEALTH PHYSICS NETWORK TELEPH0 HTS The NRC's Health Physics Network (HPN or Black Phone) connects all Nuclear Power Plants and Fuel Facilities to NRC Regional Offices and to NRC Head-quarters Operations Center. The phone is intended to support Health Physics Operations in an emergency but can be used for daily voice traffic and fac-simile transmittal. The Station has jacks for the HPN phones in the Performance Office (Control l Room 1 & 2) and in the Oconee Training Center. The phone is used normally with the exception; NO DIAL TONE OR RINGING IS HEARD. In addition, ringing only lasts 30 seconds, so after 30 seconds if the party has not answered, you must hang up and redial. For convenience, the codes most often used are listed below: ' HPN Phone Code 1. NRC region 2 (Atlanta) office 2. NRC headquarters (24 hours) 3. B&W Research Center 4. Oconee NRC Resident Inspector 5. Oconee Nuclear Station 6. All NRC region 2 Resident Inspectors 7. All region 2 Operating Nuclear Plants In addition, the calling party may " conference" any phones during convers'ation by simply dialing the appropriate code (s). Any number of stations may be added in this manner. l l I Rev. 83-3 9/30/83 l

Depressing the Activate button starts operation of the newly selected mode. 3.6 The radiation monitor on the control panel wi11 provide levels of i radiation at the sample panel. If the radiation monitor is not j working properly, then a portable survey instrument will be used to determine radiation levels. l~ 3.7 If problems with the pressure and/or temperature gauge are evident, j~ such as going off scale or erratic response, the Selector Switch must be turned to the OFF mode and sampling discontinued until the i problem is corrected. ) 3.8 If the sampling system cannot be operated, then HP/0/B/1009/15 (Ref. l 2.4) will be used as an alternate method for obtaining a containment l air sample. j. 3.9 Enclosure 5.5 will be used to check off the steps as the procedure is completed. t 3.10 Operations must complete Enclosure 5.3 or 5.4 to bypass the Hydrosea Analyser to bring containment air to the sampling system and to return { the Hydrogen Analyser to service after sampling is complete by Enclosure 5.6 or 5.7. These enclosures shall be independently verified to ensure that containment integrity is maintasned. The Operations 2 Unit Supervisor shall desigaste one " doer" and one " verifier" as required by References 2.6 and 2.7. t 1 3.11 The front side o'f the sample panel is the side which contains the door. 1 The left and right side of the sample panel will be determined by ] using this fact. j-3.12 If radiation levels eaceed 16 R/hr and cannot be reduced by purging 3: the system, secure operation of the panel, move to a low background area, and contact the Station Nealth Physicist or his designee for i further instructions. 3.13 Before sampling operations besia, the decision must be made based on radiological conditions La the reactor building and the sampling area { whether to use a 100 mi gas bomb or a calibrated syringe for the gas sample. During emergency conditions, this decision will be ande by the Station Nealth Physicist or his designee. 3.14 Enclosure 5.8, Va1ve Checklist for Sample Panel, any be used to provide assistance is determining flow inside the sample panel.

ff-{i DUKE POWER COMPANY OCONEE NUCLEAR STATION OPERATING PROCEDURE FOR POST-ACCIDENT CONTAIN> LYT AIR SAMPLING SYSTEM 1.0 Purpose This procedure' describes the operation of the Post-Accident Containment Air Sampling System which is used to obtain a prompt containment air sample under accident conditions while keeping radiation exposure ALARA.

This procedure is also used to perform the semi-annual functional test of the system. 2.0 References 2.1 Duke Power Company Nuclear Station Post-Accident Containment Air Sampling System Manual 2.2 HP/0/B/1006/07 Procedure for Preparation of Gas Calibration Sources 2.3 CP/1/A/2002/04C, Operating Procedure for the Post Accident Liquid Sampling (PALS) System 2.4 HP/0/B/1009/15, Procedure for Sampling and Quantifying High Level Gaseous, Radiciodine and Particulate Radioactivity 2.5 EP/0/A/1800/04, Loss of Coolant j. 2.6 Station Directive 4.2.5, Independent Verification Requirements 2.7 Station Directive 3.1.37, Interim Control of Independent Verification Requirements 3.0 Limits and Precautions l 3.1 The sampling cycle will require two (2) qualified technicians approximately one (1) hour per sample, of which about ten (10) minutes will be spent in the sample panel area. One qualified technician will operate the control panel while the other will perform transit duties to and from the panel. l' l 3.2 Personnel communications can be achieved by phone. l t Unit 1 & 2 - Ext. 1268 (by column AX-38) l Unit 3 Ext. 1396 (by door to RCA) 3.3 The following items' will never be used on the panel. a. Trap Area Evacuation l b. Fast Sample Dilution

i HP/3/A/1009/17 Page 2 of 8 3.4 The Recire Pumo must never be used at any pressure other than 0 inches of Mercury. 3.5 Moving the Selector Switch from one mode to another stops all current system operations. Depress'ing the Activate butt'on starts operation of the newly selected mode. 3.6 The radiation monitor on the control panel will provide levels of radiation at the sample panel. If the radiation mon'itor is not working properly, then a portable survey instrument will be used to determine radiation ~1evels. 3.7 If problems with the pressure and/or temperature gauge are evi ent, such as going off scale or erratic response, the Selector Switch must be turned to the OFF mode and sampling. discontinued until the 2 problem is correctrl. 3.8 If the sampling system cannot be operated, then HP/0/B/1009/15 (Ref. 2.4) will be used as an alternate method for obtaining a containment air sample. 3.9 Enclosure 5.5 will be used to check off the steps as the procedure is completed. i 3.10 Operations must complete Enclosure 5.3 or 5.4 to bypass the Hydrogen Analyzer to bring containment air to the sampling system and to return the Hydrogen Analyzer to service after sampling is complete by Enclosure 5.6 or 5.7. These enclosures shall be independently verified to ensure that containment integrity is maintained. The Operations Unit Supervisor shall designate one " doer" and one " verifier" as required by References 2.6 and 2.7. 3.11 The front side of,the sample panel is the side which contains the door. The left and right side of the sample panel will be determined by using this fact. 3.12 If radiation levels exceed 16 R/hr and cannot be reduced by purging the system, secure operation of the panel, move to a low background area, and contact the Station Health Physicist or his designee for. l further instructions. 3.13 Before sampling operations begin, the decision must be made based on radiological conditions in the reactor building and the sampling area whether to use a 100 ml gas bomb or a calibrated syringe for the gas i sample. During emergency conditions, this decision will be made by the Station Health Physicist or his designee. 3.14 Enclosure 5.8, Valve Checklist for Sample Panel, may be used to provide assistance in determining flow inside the sample panel. It is not intended to provide a verification for valve operation. 3.15 During accident conditions, the keys needed for sampling will be located in the Shiftman's key cabinet. r e r*- e --e'*, +- ' + -
