| 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.                                           |
|                                                                              |

| "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).            |
|                                                                              |
