| DEGRADED APPENDIX "R" FIRE BARRIER |
| |
| While conducting a walk down inspection of 10CFR50 Appendix R Barriers, two |
| degraded gypsum walls were identified. The two walls are intended to serve |
| as three hour rated Appendix R barriers. The inspection of the walls |
| revealed that a segment of the walls approximately 6 feet by 6 inches was |
| not constructed as required. The two walls provide separation of safe |
| shutdown equipment in the event of an Appendix R design basis fire. The |
| walls separate the charging pumps, a dedicated shutdown system component, |
| from the safety injection pumps which are alternate shutdown system |
| equipment. |
| |
| Although the walls are not constructed as designed, they appear to be |
| completed to about 75% of design and are judged capable of providing some |
| protection. Nevertheless, the walls are declared inoperable and |
| compensatory actions according to the Kewaunee Fire Plan have been |
| initiated. The walls are declared inoperable due to not having any |
| documented analysis to support the design basis rating. |
| |
| The licensee notified the NRC resident inspector. |
| |
| * * * UPDATE AT 1517 ON 6/13/01 BY HARRINGTON RECEIVED BY WEAVER * * * |
| |
| The licensee has retracted this event based upon further review. On 4/19/01 |
| Kewaunee Nuclear Power Plant (KNPP) reported to NRC via the Event |
| Notification System (ENS) an unanalyzed condition related to two Appendix R |
| fire barriers. The report was made based on a cursory visual inspection of |
| two barriers that appeared to be missing a portion of a layer of gypsum |
| board. Based on what appeared to be less than the three required layers of |
| gypsum board, a conservative assumption was made that the barriers did not |
| meet design requirements. Since the ENS report was filed, the barriers were |
| partially disassembled to gather data for-performing a fire hazards analysis |
| of the apparently degraded barriers in accordance with Generic Letter 86-10. |
| Disassembling the barriers revealed that what appeared to be a partially |
| missing layer was in fact an additional partial layer of gypsum board. |
| |
| Based on the additional data gathered from disassembling the barriers, the |
| barriers met design requirements for a three hour rated Appendix R fire |
| barrier. Therefore, the barriers were not degraded and an unanalyzed |
| condition never existed. Consequently, the reporting criteria for an |
| unanalyzed condition was not exceeded and is the basis for retracting the |
| ENS report notification made on 4/19/01. |
| |
| The licensee notified the NRC resident inspector. |

| DAMAGED MOISTURE/DENSITY GAUGE |
| |
| A Troxler Model 3440 moisture/density gauge (s/n 25332), containing one 8 |
| mCi Cs-137 and one 40 mCi Am-241/Be sources, was slightly damaged when it |
| was struck by a roller. The area surrounding the gauge was immediately roped |
| off until the gauge could be surveyed. The licensee stated that the sources |
| were retracted at the time of the event and results of surveys and wipe |
| tests were negative. The damage appears to be limited to a slight denting |
| of the plastic cover. The licensee has visually inspected the sources but |
| did not observe any damage. |

| 60 DAY OPTIONAL REPORT IN ACCORDANCE WITH 10 CFR 50.73(a)(1) |
| |
| "During performance of a loss of offsite power test with a LOCA, an |
| automatic start of the A and B emergency diesel generators, the A and B core |
| spray systems, and the A, B, C and D low pressure coolant injection pumps |
| occurred. All actuations were complete and functioned as designed. The |
| start was inadvertent and occurred when a 125 VDC knife blade was closed. |
| The switch was installed as part of the procedure and was wired incorrectly |
| such that when it was closed it caused an inadvertent LOCA signal to the |
| affected systems." |

| TRANSPORTATION REPORT INVOLVING RAD WASTE SHIPMENT FROM FERMI TO BARNWELL, |
| SOUTH CAROLINA |
| |
| "Event notification resulting from an offsite notification of a |
| transportation accident involving a radioactive waste shipment from Fermi 2 |
| to Barnwell, South Carolina. NRC reportable under 10CFR50.72(b)(2)(xi) any |
| event or situation for which notification to other government agencies has |
| been made. |
| |
| "At approximately 0530 hours on 06-13-2001, a Hittman Transport vehicle |
| transporting Class 'A' radioactive waste material [proper shipping name: |
| Radioactive Material, Low Specific Activity, n.o.s. 7, UN2912, Fissile |
| Excepted, Compacted Dry Active Waste] from Enrico Fermi 2 facility to |
| Barnwell, SC was involved in a vehicle accident west of Columbia, South |
| Carolina. |
| |
| "Hittman Transport notified the South Carolina Department of Health and |
| Environmental Control at approximately 0805 hours on 06-13-2001 concerning |
| the transportation accident. Hittman Transport also notified Fermi 2 at |
| approximately 0810 hours on 06-13-2001 of the vehicle accident. |
| |
| "The transportation accident was related to rain storm activity in the area |
| and the driver of a passenger vehicle, responsible for the accident, |
| received a traffic citation for speed too fast for conditions. The tractor |
| suffered minor damage, but once released by the South Carolina State Police |
| was able to be driven approximately 6 miles to a repair facility. No damage |
| was noted to the trailer, shipping cask, or cask tie down equipment at the |
| accident scene |
| |
| "At the repair facility, a mechanic evaluated the tractor condition and |
| cleared the tractor and trailer for continued service to the Chem Nuclear |
| Consolidation Facility in Barnwell, SC. The driver of the tractor performed |
| a dose rate survey of the trailer and the dose rates were unchanged from the |
| measured values at the Fermi site. |
| |
| "Fermi 2 does not intend to submit a press release in Michigan since the |
| accident occurred in South Carolina and the proper South Carolina agencies |
| were notified. |
| |
| "A follow up report is not anticipated, since no damage to the waste |
| shipping cask was noted at the repair facility." |
| |
| The licensee informed the NRC resident inspector. |

| PARTIAL LOSS OFFSITE COMMUNICATIONS |
| |
| On Wednesday, June 13th at 0839, a lightning strike caused a loss of the |
| commercial phone systems at the Monticello Nuclear Plant Site. This |
| affected phones in the control room and Technical Support Center as well as |
| plant paging capabilities. One commercial phone line in the control room, |
| the ENS system, auto-ring hotlines to the State EOC/Duty Officer, fax |
| capabilities and the Radio System to Off-site agencies remained operational. |
| Notification to the State and Local Counties were made informing them of the |
| degraded communication capabilities. The EOF phone system remained |
| operational. All communication systems were restored at approximately 1100 |
| on June 13th. |

| A SMALL QUANTITY OF SPECIAL NUCLEAR MATERIAL UNACCOUNTED FOR |
| |
| During the process of investigation of the Transverse In-Core Probe (TIP) |
| detector accountability issue reported on 6/8/01 (EN 38059) it has been |
| discovered that one additional detector cannot be readily accounted for. |
| This was discovered during verification of the detectors installed in the |
| TIP machines. The TIP detector is a fission chamber that utilizes |
| approximately 1 mg of enriched uranium and is therefore considered Special |
| Nuclear Material (SNM). |
| |
| During 1975 to 1986 Pilgrim did not track TIP detectors as SNM due to the |
| detectors containing 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. It Is |
| believed that this TIP detector has been properly disposed of as radioactive |
| waste and is not in the public domain. Investigation is continuing. |
| |
| The licensee notified the NRC resident inspector. |
