| BOTH LOW PRESSURE COOLANT INJECTION (LPCI) PATHS TEMPORARILY INOPERABLE |
| |
| Procedure inadequacies for venting RHR System using Ops Manual B.08.01.03-05 |
| resulted in Tech Spec LCO(s) 3.5.A declaring both LPCI Injection Paths |
| inoperable (72 Hour LCO) and Tech Spec 3.5.C for one Division of |
| Containment Spray and Cooling inoperable (7 Day LCO) NOT entered. Contrary |
| to Ops Procedure #2145 RHR System Discharge Venting these LCO(s) should be |
| entered when RHR is vented. Notifications are being made because a vent |
| valve was opened which made both LPCI Injection Paths inoperable. This |
| condition at the time of discovery could have prevented the fulfillment of |
| the safety function or system that is needed for Residual Heat Capacity. |
| The vent valve is closed and verified closed. The RHR System is Operable |

| "On April 15, 2001, we reported that the opening of a vent valve made both |
| LPCI Injection Paths Inoperable causing the loss of the LPCI safety |
| function. This operation was a planned evolution in accordance with approved |

| was not a loss of the LPCI safety function and thus this is not reportable |
| per the guidance in NUREG 1022, page 56." |

| HPCI DECLARED INOPERABLE DUE TO A FAULTY FLOW INDICATING SWITCH |
| |
| With DAEC operating in mode 1, at approximately 47% power, HPCI was declared |
| inoperable due to a faulty flow indicating switch which is utilized to |
| position the minimum flow valve. A 14-day LCO was entered per Technical |
| Specification 3.5.1, condition F, at 2133 on 6/7/01. This condition is |
| reportable under 50.72(b)(3)(v)(D) and 50.73(a)(2)(v)(D) as a failure of a |
| single train of equipment required to mitigate the consequences of an |
| accident. |
| |
| While an in-plant operator was performing his rounds within the HPCI room, |
| he discovered that flow indicating switch, FS2310, which should indicate |
| total HPCI flow, indicated approximately -170 gpm rather than the expected |
| zero gpm. The HPCI pump was not in operation. This flow switch is |
| interlocked with the HPCI minimum flow valve, allowing it to open with total |
| HPCI flow less than 300 gpm and HPCI discharge pressure greater than 125 |
| psig. The flow switch would close the minimum flow valve once HPCI total |
| flow reached 600 gpm. With the correct operation of the HPCI minimum flow |
| valve in question, HPCI was declared inoperable. |
| |
| It is believed that the cause of the faulty indication is air in the |
| instrument sensing lines feeding the flow switch. Troubleshooting efforts |
| will begin early tomorrow morning. |
| |
| The NRC Resident Inspector was notified |

| SPECIAL NUCLEAR MATERIAL (SNM) REPORT INVOLVING 1 MILLIGRAM U-235 |
| |
| "During [the] process of replacing the 'A' Transverse In-Core Probe (TIP) |
| Detector, the old detector was removed and its serial number recorded. The |
| serial number was not the serial number expected. The expected serial |
| number was 6553444 and the detector that was removed had serial number |
| 6608500. The TIP detector is a fission chamber that utilizes approximately |
| 1 milligram of enriched uranium and is therefore treated as SNM. |
| |
| "During 1975 to 1986, Pilgrim did not track TIP detectors as SNM due to |
| being less than one gram of SNM. It is suspected that during this time |
| frame this detector was changed out. In 1987 a records search was made but |
| did not reveal maintenance performed on this detector. However, an |
| intensive records search will be performed as well as corrective actions yet |
| to be determined." |

| POSSIBLE SPENT FUEL STORAGE CAST DEFECT AND POTENTIAL SIGNIFICANT REDUCTION |
| IN EFFECTIVENESS OF THE SPENT FUEL STORAGE CASK CONFINEMENT SYSTEM DUE TO |
| FAILURE OF MULTI-PURPOSE CANISTER (MPC) VENT AND DRAIN CAPS TO FULLY CLOSE |
| (4-HOUR REPORT) |
| |
| As part of the dry storage project, the licensee has loaded one MPC-68. |
| (This MPC holds 68 fuel bundles.) Subsequent to system vacuum drying and |
| helium backfilling, the vent and drain caps failed to fully close (at 0715). |
| These caps are currently about half closed, and they appear to be stuck in |
| that position. |
| |
| At this time, the licensee is not aware of the loss of any helium. Licensee |
| personnel have snooped for helium in the area and near the fittings. |
| Licensee personnel are also currently in the process of installing pressure |
| gauges to verify that the proper amount of helium remains in the MPC. The |
| licensee plans to place a helium purge on the system if it is determined |
| that helium is being lost. The licensee also notified the cask supplier |
| (Holtec International). The supplier informed the licensee that the presents |
| of helium will keep the system closed. |
| |
| The technical specifications that apply to dry storage state that the MPC |
| shall be dry and helium filled, and a helium backfill density limit is also |
| specified. The licensee stated that this technical specification density |
| requirement was met before the attempt to close the vent and drain caps. |
| At this time, the licensee believes that this limit is still being met. |
| However, the licensee is not positive that this limit is being met with the |
| vent and drain caps in the current position. Therefore, the applicable |
| technical specification limiting condition for operation (LCO) was entered. |
| This LCO requires the licensee to perform an engineering evaluation to |
| determine the impact of helium differential within 72 hours and to develop |
| and initiate corrective actions necessary to return the MPC to an analyzed |
| condition within 14 days. |
| |
| In addition, the applicable technical specifications also specify an MPC |
| helium leak rate limit. The LCO for this specification was also entered. |
| It requires the licensee to perform an engineering evaluation to determine |
| the impact of increased helium leak rate on heat removal capability and |
| offsite dose within 24 hours and to develop and initiate corrective actions |
| necessary to return the MPC to an analyzed condition within 7 days. (The |
| supplier is currently performing an engineering evaluation for the licensee, |
| and the results are expected to be available later today.) |
| |
| The licensee is making this notification as a 4-hour report in accordance |
| with 10 CFR 72.216(a)(1) and (2) for any instance of a defect in any spent |
| fuel storage cask structure, system, or component which is important to |
| safety and for a significant reduction in the effectiveness of any spent |
| fuel storage cask confinement system during use of the storage cask under a |
| general license issued under 10 CFR 72.210. |
| |
| HOO NOTE: In accordance with 65 FR 63788 on 10/25/00, the reporting |
| requirements of 10 CFR 72.216 were revised (effective 01/23/01) to require |
| that licensees make initial and written reports in accordance with 10 CFR |
| 72.74 and 72.75. Therefore, more appropriate reporting requirements for |
| this 4-hour report are believed to be 10 CFR 72.75(b)(2) and (3). |
| |
| The licensee plans to notify the NRC resident inspector. |
