| MISSING THICKNESS MEASURING GAUGE |
| |
| On 07/08/02 Mayo Construction company notified the Massachusetts Radiation |
| Control Program that a 50 millicurie Sr-90 thickness paper measuring gauge |
| has been missing since April/May of this year. It is believed that it was |
| sent out as scrap metal to the Prolerized New England scrapyard which is |
| located in Everett, MA. Mayo Construction company recently acquired Perkit |
| Folding Box Corp, which had the general license for the missing gauge and |
| they were unaware of the thickness measuring gauge. The gauge manufacturer |
| is Fife\DMC\Radiometry of Gaithersburg, Md. The source was manufactured by |
| Amersham. The source was installed in a C-ARM type gauge in 1991 by |
| TechControl of Mountain City, Georgia. The gauge is contained in a black |
| box measuring 4"x11"x11" and it is labeled on the outside as containing |
| radioactive material. The serial number on the gauge is 2412BC. Radiation |
| levels on the outside of the gauge with its shutter closed is 40 to 50 |
| milliRad/hr. Prolerized New England scrapyard has been notified and the |
| licensee is still searching for the missing gauge. |

| CONTAINMENT ATMOSPHERE DILUTION NITROGEN INVENTORY NOT MEETING TS
|
| REQUIREMENTS |
| |
| During routine daily instrument checks on July 9, 2002, the control room |
| operator found the Containment Atmosphere Dilution (CAD) Nitrogen inventory |
| just above the Technical Specification required inventory line of 67,000 scf |
| (2150 psig and 90�F). The previous day instrument check had the CAD |
| nitrogen inventory at 2250 psig and 94�F (approximately 69,000 scf). |
| |
| An operator was dispatched to the CAD compressor building to raise nitrogen |
| pressure by operating the CAD compressor. As the in-plant operator was |
| starting the CAD compressor, the control room operator again checked the |
| pressure and temperature of the CAD storage bottles and found that it fell |
| just below the require 67,000 scf line (2110 psig and 84�F). The startup of |
| the CAD compressor requires the draining of the suction receiver and opening |
| of the suction and discharge valves. This process consumed enough nitrogen |
| inventory to go below the Technical Specification value of 67,000 scf. |
| |
| At 2304, the CAD system was declared inoperable per Technical Specification |
| 3.6.3.1. A and a seven day LCO entered. The CAD compressor was operated to |
| restore CAD nitrogen volume and the CAD LCO was exited at 2330 when CAD |
| inventory was greater than the required Technical Specification of 67,000 |
| scf. |
| |
| During subsequent investigation, it had been determined that surveillance NS |
| 730301, Functional Check and Calibration of Containment Atmosphere Dilution |
| System had been performed during the dayshift on July 9, 2002. During this |
| surveillance, it performs a functional check of the CAD system by performing |
| a flow of nitrogen from the CAD bottles through a test rig thus using a |
| portion of the CAD nitrogen inventory. At the completion of the |
| surveillance, the check of the CAD nitrogen inventory was just above the |
| Technical Specification line. The surveillance was completed at 1404 and at |
| that time no action was undertaken to restore margin to the CAD nitrogen |
| inventory Technical Specification requirement. |

| ALERT NOTIFICATION SYSTEM SIRENS FOUND INOPERABLE |
| |
| "At approximately 1515 CDT, a routine test of the Alert and Notification |
| System sirens in Manitowoc County, WI revealed that all 14 of 14 sirens in |
| the county could not be activated remotely from the county's dispatch |
| center. This event did not affect the ability to activate these 14 sirens |
| remotely from Point Beach Nuclear Plant. The county believes that their |
| transmitter tower had been hit by lightning. Powering down and restarting |
| the transmitter restored the county's siren activation system to operation |
| at 1657. All sirens are now fully operational. |
| |
| "Although no major loss of sirens actually occurred, this notification is |
| being conservatively made because the county is the entity that normally |
| activates the sirens and would not have been able to do so without first |
| contacting Point Beach Nuclear Plant. " |
| |
| The NRC Resident Inspector will be notified of this event by the licensee. |

| INITIATION OF PLANT SHUTDOWN FROM 82% AS REQUIRED BY TECH SPEC 3.0.3 |
| |
| It was determined that reasonable assurance of continued operability of |
| Safety System Components associated with Unit 2 steam lines could not be |
| supported. They had noticed perturbations since the beginning of June |
| indicating a problem with their steam separators. They have since had an |
| operability and loose parts evaluation for this and recently experienced |
| another perturbation that's calling into question the loose parts |
| evaluations. Therefore, the licensee is assuming that there may be a loose |
| parts problem, so they have commenced plant shutdown at 0241 and are to be |
| in hot shutdown in 12 hrs and cold shutdown in 36 hrs. |
| |
| The NRC Resident Inspector was notified. |
