| MAIN CONTROL ROOM HVAC EMERGENCY VENTILATION DECLARED INOPERABLE |
| |
| "During performance of scheduled monthly surveillance testing, it was |
| determined that overall differential pressure on the Main Control Room HVAC |
| Emergency Ventilation Train Air Filtration Unit (AFU) was out of |
| specification high. The AFU is a single train system required to provide |
| habitable conditions for control room personnel during design basis accident |
| conditions. This condition is reportable under the requirements of SAF 1.17 |
| 'Could alone have prevented safety function.' and 10CFR50.72(b). This |
| condition places both Units in a 7 day shutdown LCO." |
| |
| The licensee will inform the NRC Resident Inspector. |

| |
| A more detailed review performed by Dresden Operations and Engineering |
| personnel has determined that the Differential Pressure across the Air |
| Filtration Unit filter could be up to a maximum of 10 inches of water gauge |
| and perform its design function. The Technical Specification value will be |
| increased to the maximum allowable value (at least 8.0 inches of water |
| gauge); which will remain within the design parameters required for each |
| component of the Control Room HVAC system. The Control Room HVAC system was |
| able to perform its intended safety function and therefore the reportability |
| of CFR 50.72(b)(2)(iii)D does not apply to this condition. NRC R3DO (Jim |
| Creed) notified. |
| |
| On 07/07/00 at 0205 CT the Control Room HVAC Air Filtration Unit |
| Differential Pressure was found to be at 6.03 inches of water which is above |
| their Technical Specification 3/4.8.D during a routine surveillance test. |
| |
| The NRC Resident Inspector will be notified of this event retraction by the |
| licensee. |

| INDUSTRIAL RADIOGRAPHY SOURCE STUCK IN THE OUT POSITION |
| |
| Conam Inspection was performing radiographs at the Tosco Refinery in |
| Trainer, PA. During the performance of a shot, the source assembly fell |
| over denting the source tube preventing the recovery of the source (64 |
| curies of Iridium-192). The area had already been secured for the |
| radiography operation and lead shot was used to cover the source until |
| recovery of the source could be made. The regional Radiation Safety Officer |
| (RSO) was contacted and reported to the site. Repairs were made to the |
| source tube and the source was recovered. |
| |
| A thirty day written report will be made. |

| POTENTIAL OIL SPILL TO JAMES RIVER |
| |
| REPORT IS BEING MADE UNDER CORE OF VIRGINIA 62.1-44.34:19, REPORTING OF |
| DISCHARGE. |
| |
| WHILE PERFORMING WORK ON FISH FLUME PIPING AT THE LOW LEVEL INTAKE |
| STRUCTURE, A BACKHOE LOST TRACTION AND SLID INTO DEEPER WATER. THE BACKHOE |
| WAS IN STATE WATERS (JAMES RIVER) FOR THIS EVENT. FUEL OIL WAS REMOVED AND |
| POTENTIAL OIL PATHS WERE PLUGGED TO PREVENT OIL DISCHARGE TO THE JAMES |
| RIVER. ALSO AN OIL BOOM WAS PLACED AROUND THE BACKHOE. NO OIL WAS OBSERVED |
| ON THE SURFACE OF THE WATER. THE STATE DEQ AND NATIONAL RESPONSE CENTER |
| HAVE BEEN NOTIFIED OF THE THREAT THAT OIL WILL ENTER STATE WATERS. THIS |
| REPORT IS BEING MADE UNDER CODE OF VIRGINIA 62.1-44.34:19, REPORTING OF |
| DISCHARGE. |
