| FILTERED EXHAUST FANS CANNOT BE OPERATED IN PARALLEL |
| |
| "Based on Unit 1H and 1J emergency bus logic testing performed on 4/18/00 |
| and 4/19/00 in accordance with 1-OPT-ZZ-001 and 1-OPT-ZZ-002, it has been |
| concluded that the Cat 1 Filtered Exhaust Fans, 1-VS-F-58A & B, will not |
| operate in parallel without tripping one or both fans. As a result, an event |
| or condition that alone could have prevented the fulfillment of a safety |
| function of structures or systems that are needed to control the release of |
| radioactive material, or mitigate the consequences of an accident exists for |
| Surry Units 1 and 2. This condition is reportable in accordance with 10 CFR |
| 50.72(b)(2)(iii). |
| |
| "Both fans have been tested by operating the fans individually. This testing |
| has determined that operation and performance of each fan is entirely |
| satisfactory when operated independently. |
| |
| "The current system alignment is that one of the two fans is in the |
| pull-to-lock position, and the other fan is in automatic stand-by. In this |
| configuration, one fan is operable, and fully capable of performing its |
| required functions. Unit 2 entered a 7 day Technical Specification 3.22.B |
| action statement on 4/18/00 at 1240 hours as a result of this condition. |
| |
| "The Surry Emergency Operating Procedures provide required directions to |
| place a Cat 1 Filtered Exhaust Fan in service, if the fans fail to |
| automatically start upon initiation of a Safety Injection. In the current |
| configuration, if the operable Cat 1 Filtered Exhaust fan fails to start, |
| the fan that is currently in PTL can be immediately placed in service." |
| |
| The NRC resident inspector has been informed of this event by the licensee. |
| |
| * * * UPDATE ON 5/18/00 @ 1243 BY HARROW TO GOULD * * * RETRACTION |
| |
| NUREG 1022, Event Reporting Guidelines for10CFR50.72 and 50.73. states that |
| "Reasonable operator actions to correct minor problems may be considered; |
| however, heroic actions and unusually perceptive diagnoses, particularly |
| during stressful situations should not be assumed." |
| |
| Both CAT 1 FiItered Exhaust Fans were proven to operate satisfactorily when |
| tested individually, and only one fan is needed to meet the system design |
| requirements. If both fans had tripped after automatically starting from a |
| Safety Injection signal, the Emergency Operating Procedures (EOP's) would |
| direct that one fan be started. This is accomplished from the control room, |
| and does not require unusual actions from the operator. The Surry DBA Dose |
| Analysis assumes that filtration of ECCS leakage begins 30 minutes |
| post-accident, which is ample time to perform the EOP action of starting a |
| Filtered Exhaust Fan if none are running. |
| |
| Based on the above review of the event and the information in NUREG 1022, it |
| has been determined that this event was not immediately reportable, as |
| existing Emergency Operating Procedures would ensure that at least one fan |
| is running within the required time after a Safety Injection signal is |
| received. |
| |
| This notification is being made to retract the report made on 4/19/00 based |
| on the above discussion. |
| |
| The NRC Resident Inspector was notified. Notified the Reg 2 |
| RDO(Wert). |

| POST-ACCIDENT SAMPLING SYSTEM ISOLATION DURING TAGOUT |
| |
| While performing a tagout on the 'A' train of the post-accident sampling |
| system (PASS) H2/O2 sampling system, solenoid isolation valve SV-5065-20B, |
| which is a 'B' train valve, closed unexpectedly. The licensee restored the |
| 'A' train of PASS H2/O2 monitoring to service and closed the redundant |
| solenoid isolation valve in the 'B' train. The licensee declared valve |
| SV-5065-20B inoperable. |
| |
| After review of system electrical diagrams, the licensee determined that the |
| closure of valve SV-5065-20B was appropriate, although its closure was not |
| anticipated in the tagout procedure. The NRC resident inspector has been |
| informed of this event by the licensee. |

| |
| The licensee is retracting this notification in accordance with NUREG-1022, |
| Section 3.3.2, Paragraph 5. The licensee has determined that this event did |
| not constitute an ESF actuation because only a portion of the system logic |
| tripped. The NRC resident inspector has been informed of this retraction by |
| the licensee. Notified R1DO (Lew). |

| OUTSIDE DESIGN BASIS - FOULING OF THE REACTOR BUILDING CLOSED COOLING WATER |
| HEAT EXCHANGER (RBCCW HX). |
| |
| Surveillance testing has identified fouling of the Salt Service Water (SSW) |
| side of the RBCCW HX. The extent of the fouling on one of the two heat |
| exchangers would prevent design basis containment heat removal post-accident |
| at maximum design basis ultimate heat sink (UHS) temperature (75�F). |
| Engineering evaluation has determined that design basis heat removal can be |
| achieved with UHS temperature less than 70�F. Periodic evaluation will be |
| performed to ensure that additional fouling has not further degraded the |
| heat exchangers heat transfer capability. |
| |
| The licensee will inform the NRC resident inspector. |

| * * * RETRACTION 1653 5/18/2000 FROM ERIC OLSON TAKEN BY BOB STRANSKY * * * |
| |
| The licensee has determined that the unit was not operated outside of the |
| design basis. At the time of the report, the seawater temperature was 50�F. |
| Therefore, the licensee is retracting this notification in accordance with |
| NUREG-1022, Section 3.2.4. The NRC resident inspector has been informed of |
| this retraction by the licensee. Notified R1DO (Lew). |

| OFFSITE NOTIFICATION REGARDING THE FAILURE OF A MAIN DAM SKIMMER GATE TO |
| CLOSE |
| |
| The following text is a portion of a facsimile received from the licensee: |
| |
| "[The] Federal Energy Regulatory Commission (FERC) was notified at 0730 on |
| 05/18/00 in accordance with 18CFR12.10(a)(1) for a condition affecting the |
| safety of the project." |
| |
| "Skimmer gate 1B at the main dam failed to close under normal operating |
| conditions. The gate is currently open, providing minimum flow. Corrective |
| action is in progress." |
| |
| The licensee stated that the skimmer gate is used to provide minimum flow |
| downstream to the river and to provide adequate level control of the main |
| reservoir for the lake (which supplies cooling water to the plant). The |
| required downstream flow of 40 scfm is currently being maintained. |
| |
| The licensee notified the NRC resident inspector. |

| MISSING RADIOACTIVE SOURCE |
| |
| The licensee reported that a 200 mCi Cs-137 source was discovered to be |
| missing from a group of sources removed from the Muskogee Power Plant for |
| disposal. Several Omart model SHDP source holders (with sources) were |
| transferred to Radiation Technology, Inc., a contractor, for disposal. These |
| source holders had been stored in a warehouse at the power plant for some |
| time before being transferred to the contractor. The licensee was notified |
| on 5/17/2000 by the contractor that one of the source holders was empty. The |
| licensee has searched their facility for the source but has been unable to |
| locate it. |
| |
| The licensee has already contacted NRC Region 4 (L. Howell). |
