| BOTH RIVER WATER SUPPLY SYSTEMS WERE DECLARED INOPERABLE.                    |
|                                                                              |
| At 0230 the River Water Supply (RWS) instrument air system failed resulting  |
| in an invalid low RWS pit level alarm.  Operators restored system air        |
| pressure at 0243.  The loss of instrument air pressure also resulted in the  |
| loss of automatic traveling screen control and the screen high differential  |
| level alarm function.  Because both of the automatic traveling screen wash   |
| systems were inoperable, both RWS systems were declared inoperable for the   |
| 13 minute duration.  Failure of both systems resulted in a loss of safety    |
| function (supplies water to the Residual Heat Removal Service Water Pumps    |
| and the Emergency Service Water System). The licensee entered the applicable |
| Technical Specifications for the loss of the RWS system.  A new air dryer    |
| was installed recently and when the operator cycled the power supply to the  |
| air dryer it hung up.  This caused the Instrument Air blockage.              |
|                                                                              |
| The NRC Resident Inspector was notified of this event by the licensee.       |
|                                                                              |

| The licensee made the following corrections to the event report: (1) the     |
| operator cycled the power supply to the compressor after it stopped, not     |
| before, as noted above; and (2) there was no instrument air blockage, as     |
| stated above. Notified R3DO (Hiland).                                        |

| "The DAEC is retracting event reports 37248 (8/24/00) and 37292 (9/5/00)     |
| that involved a loss of the River Water Supply (RWS) System's instrument     |
| air. These two 10CFR50.72(b)(2(ii) reports (an event or condition alone that |
| could have prevented safety function fulfillment) were based on the initial  |
| determination that both loops of RWS System were inoperable, due, in part,   |
| to a Precaution and Limitation (P&L) contained in the system's Operating     |
| Instruction (OI-410). The loss of air had impacted a portion of the RWS      |
| screen wash support system. The P&L provides guidance on the screen wash     |
| subsystem's impact on RWS System operability. Follow-up engineering          |
| assessment has concluded that a loss of instrument air, by design, does not  |
| prevent the RWS system from fulfilling its intended safety function. The RWS |
| system would have been capable of fulfilling its intended safety function    |
| during both events.                                                          |

| "Technical Specification (TS) Bases 3.7.2 defines RWS subsystem operability  |
| as having, 'an OPERABLE UHS, one OPERABLE pump, and an OPERABLE flow path    |
| capable of taking suction from the intake structure and transferring the     |
| water to the RHRSW/ESW Stilling Basin in the pump house.' For both of the    |
| events, the only question regarding operability was that of the OPERABLE     |
| flowpath. The follow-up engineering assessment concluded that the flowpath   |
| remained operable. Actual river water flow, as indicated in the control      |
| room, was not impacted by the loss of instrument air throughout the (short)  |
| duration of these events. Also, there is no question regarding past or       |
| historical operability because the cause of the loss of air was related to   |
| air system modifications, which were in process at the time or the events.   |
|                                                                              |
| "Therefore, there was no event or condition alone that could have prevented  |
| safety function fulfillment. Once discovered, the appropriate TS action      |
| statements were entered. No TS 3.0.3. entry was made (or required to be      |
| made). There were no Operations or Conditions Prohibited by TS. No other     |
| reporting criteria apply to these events. These events are considered        |
| not-reportable under 10CFR50.72 or 10CFR50.73."                              |

| The licensee had a failure of the river water instrument air system at 1810  |
| CDT, resulting in the loss of the automatic traveling screen control and the |
| high screen differential level alarm function.  With both automatic screen   |
| wash functions inoperable, both river water supply systems were declared     |
| inoperable.  The systems were returned to operable at 1820 CDT when the      |
| alternate air dryer was placed in service, the problem being the air dryer   |
| that had been in service stopped passing air.                                |

| ESF ACTUATION - CONTROL ROOM FILTRATION SYSTEM (CREFS)                       |
|                                                                              |
| On 9/15/00, at 0446 the CREFS initiated due to receiving an actuation signal |
| based on control building high gas activity.  All automatic actions were     |
| verified to have occurred.  It was determined that the control building high |
| gas activity was caused by a temperature inversion and not an actual plant   |
| condition (i.e., radiological release).  The control building high gas       |
| activity alarm cleared at 0450 and at 0459 CREFS was returned to a normal    |
| standby lineup.                                                              |

| It was originally believed that this condition was not reportable due to it  |
| being an invalid actuation. Further review of this condition has determined  |
| that the condition was the result of a valid signal caused by an             |
| environmental condition.                                                     |

| Am-241/Be; Serial No. 47-7153. The gauge was stolen or lost on the job site  |
| September 14, 2000. The gauge was placed in the back of a company pickup     |
| without a case and was not secured. The driver/operator remembers placing    |
| the tailgate in the up/closed position. The driver had a short conversation  |
| away from the truck and then departed the worksite. While driving along      |
| RM620 between Texas Highway 183 and Interstate Highway 35 (Austin, Texas),   |
| he noticed his tailgate was in the down/open position and immediately        |
| stopped. The gauge was gone. It is not known if the gauge was stolen from    |
| the worksite or lost along the highway. The gauge was not found by a company |
| search of the route taken by the driver. A police report was filed with the  |
| Austin Police Department. Texas Licensee is Raba-Kistner (L01571-002) of     |
| Austin, Texas. The gauge was unsecured and not under direct surveillance at  |

| AGREEMENT STATE REPORT - SOURCE DETACHED FROM DRIVE ROD                      |
|                                                                              |
| "The licensee notified the WA Department of Health, Division of Radiation    |
| Protection (WDOH), of a mechanical failure involving a Ronan Engineering     |
| Company Model SA-4 gauging device.  The device is specifically licensed for  |
| density process measurements and uses a Cesium 137 sealed source, Amersham   |
| Model CDC.711M not to exceed 74 gigabecquerels (2 curies). The source is     |
| normally mounted at the end of a source rod, approximately six feet long.    |
| In this particular model version, the source rod consists of two             |
| screw-together extensions (approximately two and a half feet each) which     |
| screw into the same diameter source holder (approximately half a foot long). |
| When operating, the rod with source is lowered through the shielded storage  |
| position, into the integral and enclosed dry well tube.  When not in         |
| operation, the rod with source can be raised to place the source into a safe |
| position inside the main shielding.  An authorized user realized that a      |
| problem existed when attempting to withdraw the source to the safe position. |
| Apparently the rod did not have a normal feel when it was raised.            |
| Preliminary indication was the source had separated from the source rod and  |
| fallen to the bottom of the insertion dry well. The licensee's RSO and its   |
| health physics consultant surveyed the area and determined there wasn't a    |
| dose rate problem since the process slurry was still providing ample         |
| shielding.  The slurry was maintained in-place and the area adjacent to the  |
| dry-well access point was posted as a restricted area.                       |
|                                                                              |
| "The recovery operation took place on September 18, with WDOH staff actively |
| overseeing the operation.  The health physics consultant determined the      |
| upper source rod section appeared simply to have come unscrewed from the     |
| lower sections, apparently from the vibration of the slurry separator on     |
| which the gauge was mounted.  However, it was necessary to remove the device |
| from it's bracket and up-end it to allow the source to slide back to the top |
| of the device.  Once the end was visible the parts were screwed back         |
| together and the unit re-installed.  It was also determined that the source  |
| holder was partially unscrewed from the middle rod section as well.  Both    |
| connections were coated with "lock-tight" and tightened.                     |
|                                                                              |
| "Radiation readings increased from background to about 50 mR/hr in the       |
| general area during the recovery operation.  Contact reading on the dry well |
| near the estimated source position was greater than 5 R per hour.  Actual    |
| recovery working time was about 20 minutes.  Both individuals involved       |
| received an indicated 25 millirem exposure on their pocket dosimeters.       |
|                                                                              |
| "The health physics consultant indicated that this source rod was of an      |
| older style for this particular Ronan device.  The three other devices of    |
| this model at the licensee's facility were checked and appeared not to be    |
| in                                                                           |
| danger of separating.  The licensee plans on upgrading to a newer style rod  |
| during an up-coming maintenance shutdown.  The recovery operation was        |
| successfully completed."                                                     |
