| THREE OF FOUR MAIN STEAM RELIEF VALVES (MSRV) CONEX CONNECTORS INSTALLED     |
| BACKWARDS.                                                                   |

| While shutdown the licensee determined that 3 of 4 MSRV's had the conex      |
| connectors installed backwards.  The connectors provide the environmental    |
| qualification seal to the pilot solenoid valve.  ADS may not have functioned |
| under elevated drywell temperature conditions.                               |
|                                                                              |

| Further engineering review has determined that the valves would have         |

| A patient was prescribed a treatment plan consisting of two doses, 5040 cGy  |
| and 2000 cGy using Co-60 therapy.  The first dose was given as prescribed on |
| 5/18/99,  but the second dose was never given.   The prescribing doctor was  |
| out of town and his substitute did not notice the second half of the         |
| treatment which was written on a second piece of paper.   This error was     |
| discovered when the original doctor returned to work.   The patient was      |
| immediately notified of the mistake and requested to come in to finish the   |
| treatment.  The patient has refused further therapy.                         |
|                                                                              |

| A train 'A' toxic gas isolation signal (TGIS) occurred, causing the control  |
| room ventilation system to isolate and the train 'A' emergency chill water   |
| system to start. The TGIS was caused when the ammonia channel went into      |
| alarm. The licensee is investigating the cause of the ammonia alarm, but     |
| reported that maintenance workers were venting freon at the time of the      |
| actuation. The NRC resident inspector has been informed of this event by the |
| licensee.                                                                    |

| "Foxboro Co. has identified a potential defect with N-2A0-L2C-R or           |
| N-2A0-L2C-R with ECEP 10273, Contact Output Isolator cards that may contain  |
| specific NO152CK or CO147SS relays. These relays, supplied by Potter &       |
| Brumfield, were manufactured utilizing pure tin plated contact support arms. |
| As a result, in low voltage, low current applications, the growth of tin     |
| whiskers between adjacent metallic surfaces of the contact support arms can  |
| lead to the establishment of a resistive shunt path. This shunt path would   |
| prevent the relay from functioning as designed. This potential defect is     |
| limited to only those relays supplied by Potter & Brumfield manufactured     |
| from 1 December 1981 to 31 December 1993.                                    |
|                                                                              |
| "Foxboro is taking immediate corrective action to rectify the situation and  |
| will notify all Nuclear Utilities that have purchased this product from      |
| Foxboro during the time period affected and provide replacement relays."     |
|                                                                              |
| The representative reported that two failed relays were identified after     |
| being returned by a foreign reactor facility.                                |

| At 2200 hours on 7/8/1999,  a Nuclear Criticality Safety Analysis (NCSA)     |
| PLANT_062.A00 control was lost. Requirement #6 of the NCSA was not           |
| maintained when a cover was not placed over cell 31-4-1 stage 3              |
| converter-flange after maintenance, leaving the system open to atmosphere    |
| and therefore losing the control for moderation. This constituted loss of    |
| one contingency in a situation protected by the double contingency           |
| principle. Control #6 of NCSA-Plant062.A00 was re-established at 0027 hours  |
| on 7/9/1999, at which time a plug was installed In the opening.              |
|                                                                              |

| During quarterly valve time testing, the isolation condenser reactor return  |

| condenser to perform its function.  The cause of the failure has not been    |
| determined and is under investigation.  The plant entered a 14 day LCO based |
| on having the isolation condenser inoperable.  No other ECCS equipment is    |
| inoperable.                                                                  |
