| TECHNICAL SPECIFICATION (TS) SHUTDOWN |
| |
| "At time 2058 (EST) on 03/10/01, Unit 2 commenced a normal rampdown to cold |
| shutdown for refueling. The unit was in action statement that expires at |
| 1515 on 03/11/01. The action statement of TS 3.6.1.3.b had been entered at |
| 1515 on 03/10/01 when 2-PT-62.1 failed. This test was a routine pre-outage |
| test on the containment equipment hatch personnel access air lock. The unit |
| shutdown was planned for this date and time. Repairs to the failed |
| component will be made with unit in mode 5." |
| |
| The licensee thinks that the equipment hatch inner air lock door equalizing |
| valve is leaking by. |
| |
| The NRC Resident Inspector was notified of this event by the licensee. |
| |
| * * * RETRACTED AT 1301 EST ON 3/22/01 BY JIM CROSSMAN TO FANGIE JONES * * * |
| |
| |
| The licensee is retracting this event notification. The original |
| notification was conservatively made. At the time the plant had planned to |
| shutdown for a refueling outage and it was unknown at the time if repairs |
| could have been made within the 24 hour time clock required by technical |
| specifications. The problem with the hatch turned out to be minor in nature |
| and easily corrected, thus the plant would not have been required to |
| shutdown per the technical specifications. The problem was excessive amount |
| of hardened grease applied to the seal surface. The grease was removed and |
| the air lock successfully passed leakage testing all within about one hour. |
| |
| |
| The licensee notified the NRC Resident Inspector. The R2DO (Mark Lesser) |
| was notified. |

| DRYWELL TO TORUS BYPASS LEAKAGE NOT REEVALUATED FOR POWER RERATE |
| |
| "An unanalyzed plant condition may exist due to Drywell to Torus bypass |
| leakage as defined in Tech Spec Bases 3.7.A was not reevaluated for power |
| rerate. The original evaluation determined that the maximum allowable |
| leakage capacity was 0.12 square feet. When power rerate was being |
| evaluated, General Electric assumed that Monticello was bound by a generic |
| evaluation for the drywell to torus allowable capacity of an 0.01 square |
| feet." |
| |
| Corrective action includes a reevaluation, as appropriate. The licensee |
| informed the NRC resident inspector. |

| RCIC DECLARED INOPERABLE |
| |
| During an investigation of a ground on Div I 125/250 volt D.C. bus, the |
| source of the ground was determined to be 2E51-F008 primary containment |
| isolation valve. 2E51-F008 is the outboard steam supply to reactor core |
| isolation coolant (RCIC). It was closed and de-energized. 2E51-F008 |
| closure rendered RCIC system inoperable. |
| |
| The licensee notified the NRC Resident Inspector. |

| CONDITION OF LICENSE REPORT INVOLVING MINE IN EXCURSION STATUS |
| |
| The following is taken from a faxed report: |
| |
| Notification of a Reportable Event per License Section 11.2 |
| |
| Reported Event: |
| |
| A routine monthly water sample collected on March 21, 2001 from monitor well |
| 5MW43, exceeded 2 of its 3 upper control limits (UCLs). A confirmation |
| sample was collected March 22, which also exceeded 2 UCLs. Monitor well |
| 5MW43 was then placed on excursion status as per license Section 11.2 and |
| its sampling frequency increased to weekly. 5MW43 is a perimeter ore zone |
| monitor well located approximately 300 feet south of the Mine Unit 5 |
| boundary at the Christensen Mine, Campbell County Wyoming. Note that Mine |
| Unit 5 is currently in groundwater restoration and that the nearest |
| community is Linch, Wyoming approximately 16 miles to the southeast. |
| |
| Analysis Data: |
| |
| Conductivity |
| Uranium |
| Date Chloride mg/l umhos/cm2 |
| Alkalinity mg/I mg/l U308 |
| Sampled UCL 22.7 UCL 1004 UCL |
| 134.3 no UCL |

| 3-22-01 7.4 1133 |
| 169.0 <0.4 |
| |
| Health and Environmental Hazards: |
| |
| None |
| |
| Investigative Action: |
| |
| Collect additional samples from this well to further evaluate the water |
| quality. Since the chloride concentration remains near its baseline level, |
| it is felt that this is not an actual excursion from the Mine Unit. |
| |
| Written Notification: |
| |
| A written notification with further information will be submitted to NRC |
| Fuel Cycle Licensing Branch Chief within 7 days. |
