| DRESSER VALVES NAME PLATE AND CODE PLATE HAVE INCORRECT SET PRESSURE |

| |
| PART 21 FROM DRESSER EQUIPMENT GROUP, DRESSER VALVE DIVISION, BURLINGTON, |
| ONTARIO, CANADA. |
| |
| |
| The following noncompliance has been determined to be reportable within the |
| requirements of 10CFR Part 21. The noncompliance involves seven safety |
| relief valves that were purchased for the Hatch Electric Generating Plant by |
| the Georgia Power Company through its agent, Southern Nuclear Operating |
| Company, Inc. The valves are for use in a safely related service. |
| |
| The valves were purchased on Southern Nuclear Operating Company purchase |
| order #6040304 and produced on Dresser Valve Division sales order #119588N |
| and are further described as follows: |
| |
| Contract Item 002 Quantity 7 Part Number |

| |
| NONCOMPLIANCE SITUATION AND BRIEF HISTORY |
| |
| On Tuesday April 25, 2000, the customer was performing receiving inspection |
| and noticed that the set pressure information on the Code Plates and the |
| Name Plates do not conform to the specification requirements or the history |
| docket testing information. The customer called the Quality Assurance |
| Department of Dresser Valve Division to discuss the finding. It appears |
| that the set pressure information on the plates has been interchanged. |
| |
| A summary of the information is as follows: |

| |
| Our investigation has begun and we have conducted a full review of our |
| records to confirm that the valves are set correctly to the contract |
| requirements. A notice has been given to the customer to return the |
| affected valves to Dresser Valve Division for confirmation of the plate |
| information and correction if required. The ANI will be involved in the |
| investigation and corrective actions as required. |
| |
| We have conducted a full review of our records and confirmed that these are |
| the only valves involved. A full review of our procedures regarding plate |
| preparation, inspection and installation will be completed. Corrective |
| actions will be initiated to address the internal issues, if warranted, and |
| details will be provided in our closure reports at the completion of our |
| investigation into the cause of this situation. |

| |
| The following information was received via fax: |
| |
| "This is a summary of the event dealing with the cause and the corrective |
| actions implemented to prevent recurrence. |
| |
| "The customer returned the valves and the set pressures were confirmed to be |
| correct to the General Arrangement Drawing (GA Dwg) requirements. New |
| nameplates were produced, verified to the approved GA Dwg., and installed on |
| the valves as witnessed by the ANI. |
| |
| "It was confirmed that the incorrect nameplate information was derived from |
| internal work order data. The approved GA Dwg was not used as required. |
| |
| "Revised internal operating procedures are being implemented to ensure that |
| engineering personnel complete nameplate forms, from data appearing only on |
| the approved GA Dwg. Only the approved GA Dwg will be used to verify the |
| correctness of the data." |
| |
| Notified R2DO(Bernhard) and NRR(Hodge). |

| POTENTIAL PERSONNEL OVEREXPOSURE |
| |
| A technician employed by Yale University in the Environmental Services Group |
| expressed a concern regarding ALARA during an inventory of both byproduct |
| and accelerator produced radioactive material. He noticed a vial containing |
| Na-22 (accelerator product) in the millicurie source range sitting on its |
| side in the "cave." The "cave" is a shielded storage location for both |
| waste and byproduct material. The technician's film was sent for an |
| emergency read. The results were received at 1658EDT on 6/15/00 and |
| indicated a whole body exposure of 6930 mRem. A thyroid scan and bioassays |
| were performed with negative results. Contamination surveys were performed, |
| again with negative results. The technician had taken his film badge with |
| him to Texas during the period of time the badge was used (May). The |
| University RSO has submitted the other technicians (between 30-35) film |
| badges for reading as part of the investigation. The University has |
| contacted the state of CT. |

| ACTUATION OF THE CONTROL ROOM EMERGENCY AIR CLEANUP SYSTEM DURING |
| RADIOGRAPHY |
| |
| "On June 11, 2000, at approximately 1313 PDT, SCE was performing radiography |
| on the 56' elevation of the Unit 2 Turbine Building when the Train B |
| radiation monitor (2/3RT7824) for the Control Room Isolation Signal (CRIS) |
| actuated. At approximately 1317 PDT, the Train A CRIS radiation monitor |
| (2/3RT7825) actuated. The Train A and B Control Room Emergency Air Cleanup |
| System (CREACUS) actuated as expected. |
| |
| "SCE was performing the radiography on the Unit 2 Main Steam Throttle Stop |
| Valves with an 82 Ci iridium-192 source. The unshielded beam emanating from |
| the collimated radiographic source was directed away from the CRIS radiation |
| monitors, which are about 150 feet away. The radiography was scheduled to |
| last approximately 3.5 minutes. |
| |
| "Because the actuation of the CRIS radiation monitors did not occur as a |
| result of airborne contamination or actual plant conditions or parameters |
| satisfying the requirements for initiation of the safety function of the |
| system, SCE did not consider this to be a valid actuation requiring a |
| report. However, if a 'valid signal' were to be defined as output from a |
| radiation monitor detecting any radiation source, then this event would be |
| reportable. Because questions have been raised regarding which definition of |
| 'valid signal' is applicable in this instance, SCE is conservatively |
| reporting this condition in accordance with 10CFR50.72(b2)(ii). |
| |
| "The trend data for the CRIS radiation monitors showed no readings above the |
| setpoint of 1E-5 �Ci/cc. Because no actual airborne radioactive |
| contamination was present, this event has no safety significance. |
| |
| "At the time of this occurrence, both Units 2 and 3 were operating at about |
| 100 percent power; Unit 1 remains permanently defueled. SCE will notify the |
| NRC resident inspectors about this notification and will provide them with a |
| copy of this report." |

| AGREEMENT STATE REPORT INVOLVING A LEAKING NI-63 SOURCE |
| |
| While performing a routine wipe test on 3/9/2000 of a Varian Gas |
| Chromatograph Detector Cell at the Utah State University in Logan, UT, |
| leakage from the 8 mCi Ni-63 source was detected. Accelerated leakage tests |
| were ordered to monitor the source. On 6/5/2000 the test results indicated |
| 0.02 �Ci which exceeded the reportability criteria of >0.005 �Ci. The room |
| and surrounding area was surveyed, with the results indicating no |
| contamination. The source was removed from service and will be returned to |
| the vendor for repair or replacement. The instrument is model # |
| 02001972-00, serial # A8615. Utah has assigned incident # UT-00-0003. |
