| - LICENSEE NOTIFIED NATIONAL RESPONSE CENTER AND STATE DEP OF A CHEMICAL |
| SPILL ONSITE - |
| |
| The licensee notified the National Response Center and the State Department |
| of Environmental Protection (DEP) that approximately 5 gallons of a mixture |
| of sulfuric acid and sodium hydroxide spilled from a tank truck onto the |
| ground after a chemical reaction took place. The spill was contained within |
| a portable dike area onsite and is being cleaned up. |
| |
| The licensee plans to notify the NRC Resident Inspector. |
| |
| * * * UPDATE AT 0948 EDT ON 04/26/00 FROM ROY HARDING TO S. SANDIN * * * |
| |
| The licensee is retracting this report based on the following: |
| |
| "This is a retraction of the notification made on 04/20/00 at 2029 hours |
| (Event 36911). This event was reported as a notification of another |
| government agency [National Response Center and Pennsylvania Department of |
| Environmental Protection (PADEP)] pursuant to 10CFR50.72(2)(b)(vi). |
| |
| "On April 20, 2000 at 1930 hours while Limerick Unit 1 was shutdown for |
| refueling, 5 to 10 gallons of a dilute and partially neutralized acid |
| (Sulfuric Acid-pH 3) was expelled from a temporary trailer tank onto asphalt |
| and stone surface in an adjacent area outside a temporary dike. In |
| addition, approximately 30 gallons of the acid/sludge mixture spilled into |
| the temporary dike. The spill never threatened navigable waterways, and |
| subsequently was cleaned up within a 24 hour period. The initial |
| notification was conservatively reported based on information known at the |
| time of the event. |
| |
| "A minor spill of this nature is not reportable to the PADEP in accordance |
| with 40CFR112 and the Preparedness Prevention Plan for Limerick Generating |
| Station. This spill from a temporary tank had no impact on navigable |
| waterways and was less than the Reportable Quantity (69 gallons)." |
| |
| The licensee will inform the NRC Resident Inspector. The NRC Operations |
| Officer notified the R1DO (Noggle). |

| VARIOUS ESF ACTUATIONS DUE TO RPS BUS 3B DEENERGIZING AS A RESULT OF A |
| FAILED RELAY |
| |
| "At 2342 CDT on 04/25/00, the RPS bus 3B deenergized causing PCIS Group 2 |
| and Group 6 isolation valves to automatically close. A burnt relay was the |
| initiating condition. Group 2 outboard drywell equipment drain valve and |
| drywell floor drain valve closed. Group 6 drywell radiation monitor |
| isolation valves closed. All other expected group isolations occurred along |
| with the automatic starts of SBGT and CREV Systems. |
| |
| "Unit 3 is in Mode 5 with primary containment integrity not required. |
| |
| "This event is reportable under criteria 10CFR50.72.b.2.ii : Any event or |
| condition that results in manual or automatic actuation of any engineered |
| safety feature (ESF), including the reactor protection system (RPS)." |
| |
| RPS bus 3B was reenergized from its alternate power supply. Electricians |
| are currently troubleshooting the cause of the failed relay. There was no |
| electrical maintenance or testing ongoing at the time of the relay failure. |

| DRESSER VALVES NAME PLATE AND CODE PLATE HAVE INCORRECT SET PRESSURE |
| INFORMATION AT HATCH. |
| |
| 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 |
| 3990C-1-S4-MS-33-SC-SC-GS produced ASME Section |
| III Class 2 valves with the following serial numbers and |

| |
| 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. |

| AUXILIARY BUILDING SPECIAL VENTILATION AND CONTROL ROOM POST ACCIDENT |
| RECIRCULATION ACTUATED DUE TO A STEAM EXCLUSION SIGNAL. |
| |
| At 1342 CDT on 04/26/00, the Auxiliary Building Special Ventilation and |
| Control Room Post Accident Recirculation Systems actuated due to a steam |
| exclusion signal. Auxiliary Building Special Ventilation and Control Room |
| Post Accident Recirculation are Engineered Safety Features Systems. The |
| steam exclusion signal was due to the rupture disk on Boric Acid Recovery |
| System rupturing. Steam to the Boric Acid Recovery System was isolated. At |
| 1425 CDT, steam exclusion was reset and the Auxiliary Building Special |
| Ventilation and Control Room Post Accident Recirculation Systems were |
| shutdown. All equipment operated as designed. There was no radiological |
| release. The licensee is currently investigating why the rupture disc |
| ruptured. Nobody was injured. |
| |
| The NRC Resident Inspector was notified of this event by the licensee. |
