| C-3 DEFECTS DETECTED DURING EDDY CURRENT INSPECTION OF STEAM GENERATORS |
| |
| Indian Point 2 is conducting eddy current testing of 100% of the steam |
| generator (SG) tubes. With about 90% of the inspection complete, SG-21 and |
| SG-24 tubes have defects in greater than 1% of the tubes inspected. SG-22 |
| and SG-23 have defects in much less than 1% of the tubes inspected. The |
| majority of the defects are at the support plate intersections and in row 2 |
| U-bends. There are 41 indications in SG-21, 40 at the support plate and 1 |
| in the U-bend. There are 39 indications in SG-24, 36 at the support plate |
| and 3 in the U-bend. In accordance with Technical Specification 4.13, these |
| defects result in a C-3 classification. The testing will continue until |
| 100% of the tubes are inspected. |
| |
| The licensee notified the NRC Resident Inspector. |

| THREE FUEL ASSEMBLIES DETERMINED TO BE IN WRONG POSITIONS IN THE SPENT FUEL |
| POOL |
| |
| Unit 1 personnel determined that three fuel assemblies, in the Unit 1 Spent |
| Fuel Pool (SFP), were in positions inconsistent with the Technical |
| Specifications (TS). Preliminary assessment indicates that the Keff limit |
| of 0.95 (TS 3.7.15) for the SFP would have still been met. This condition |
| existed for ten days, since the last Unit 1 core offload. The assemblies |
| have been returned to the positions allowed by TS. An investigation is in |
| progress to determine the cause of this event and to determine if the Keff |
| limit was exceeded. There will be a 30 day written report submitted. |
| |
| The licensee notified the NRC Resident Inspector. |

| TRUCK CARRYING A GAUGE WITH A SMALL SOURCE IN IT |
| |
| On 3/21/00 at about 6:30 AM in Oxnard CA, a Federal Express truck burned due |
| to an unknown cause. It was discovered today, 3/23/00, that a thickness |
| gauge from NDC of Irwindale, CA was on the truck. The gauge contains a |
| special form source of Curium-244, 100 mCi. The source is thought to be |
| able to survive the fire and is being sought. Dr. Roy Parker, the Federal |
| Express Safety Officer, is on the scene and following up on the incident. |

| FULL REACTOR SCRAM SIGNALS GENERATED DURING TESTING WHILE REACTOR IS |
| SHUTDOWN |
| |
| With Unit 2 in a refueling outage, control room operators were performing a |
| Reactor Protection System scram discharge volume (SDV) high water level |
| bypass switch (rod block) functional test. During performance of the test, |
| control room operators placed the SDV high water level bypass switch |
| #2C71-54 in the bypass position and the reactor mode switch in the shutdown |
| position. This action caused the generation of a full reactor scram signal. |
| The Control Rod Drive System had already been deenergized and all control |
| rods were already fully inserted into the reactor core. |
| |
| Control room operators reset the reactor scram signal to normal and placed |
| the bypass switch in the normal position in accordance with the test |
| procedure. However, the bypass switch was placed in the normal position |
| before the SDV had time to drain down. With the SDV water level above the |
| high level alarm setpoint, a second full reactor scram signal was |
| generated. |
| |
| The licensee restored all systems to normal and is investigating this |
| situation, including reviewing the test procedure. |
| |
| The licensee notified the NRC Resident Inspector. |

| - 'C' INBOARD MAIN STEAM ISOLATION VALVE FAILED ITS LOCAL LEAK RATE TEST - |
| |
| During the performance of a local leak rate test of the 'C' main steam |
| isolation valves (MSIVs) with Unit 1 in a refueling outage, the inboard MSIV |
| #HV141-F022C was unable to hold pressure. This constitutes a failure of the |
| maximum path leak rate required by Tech Spec 3.6.1.3. |
| |
| This condition constitutes a degraded condition of a principle safety |
| barrier found while Unit 1 was shutdown. No other adverse conditions were |
| identified. |
| |
| Unit 1 remains safely shutdown and the licensee is conducting an |
| investigation to determine the cause of the failure. |
| |
| The licensee plans to notify the NRC Resident Inspector. |
