| "On 06/02/99 at 1630 CDT, the Plant Shift Superintendent (PSS) was notified  |
| that numerous sprinkler heads were corroded, affecting 16 sprinkler systems  |
| in C-337 and one system in C-333, such that the ability of the sprinklers to |
| flow sufficient water was called into question.  Subsequently, these         |
| sprinkler systems were declared inoperable, and TSR-required actions         |
| establishing roving fire patrols were initiated.  This deficiency was        |
| detected during scheduled system inspections conducted by Fire Protection    |
| personnel.  Currently, functionality of the sprinkler heads has not been     |
| fully evaluated by Fire Protection personnel, and the remaining cascade      |
| buildings are currently being inspected, and if necessary, this report will  |
| be updated to identify any additional areas.                                 |
|                                                                              |

| During the receipt inspection of a package, containing Technetium-99m        |
| Myoview, it was determined that a surface survey reading was greater than    |
| the limit of a White 1 tag, the reading was 1.1 mR/hr.  A wipe reading had a |
| maximum of 23.75 dpm.  The hospital contacted the source pharmacy            |
| (Mallinckrodt of Saginaw, MI) who asked them to open the package for         |
| inspection.  The hospital opened the package and performed a wipe test of    |
| the contents and the inside of the container.  The results were negative     |
| with a maximum wipe of 62.5 dpm.  A surface survey determined that one of    |
| the pigs had a surface reading of 2 mR/hr, the pharmacy asked the hospital   |
| to mark it so that it could be discarded when it is returned.  They believe  |
| that the pig has developed a crack which makes it unusable.  The dose of     |
| Technetium-99m Myoview was not damaged.                                      |

| IN PREPARATION FOR RESIN SLUICING OPERATIONS ON THE "12" MIXED BED           |
| DEMINERLIZER, THE DEMINERLIZER WAS ISOLATED AND TAGGED.   WHILE THE          |
| DEMINERLIZER WAS BEING DRAINED, IT WAS IDENTIFIED THAT THE ISOLATION VALVE   |
| WAS LEAKING BY FOR TWO MINUTES AT A REACTOR COOLANT SYSTEM LEAKRATE OF       |
| APPROXIMATELY 80 GPM.  UPON IDENTIFICATION, THE LEAK WAS IMMEDIATELY         |
| ISOLATED.  TOTAL DISCHARGE WAS APPROXIMATELY 200 GALLONS TO THE PLANT'S      |
| RADIOACTIVE WASTE SYSTEM.  THE PLANT VENT RADIATION MONITOR "1R16"  WAS IN   |
| ALARM AND HAS SINCE CLEARED THE ALARM SETPOINT.   AT 1445 IT WAS IDENTIFIED  |
| THAT THIS DISCHARGE EXCEEDED THE UNUSUAL EVENT CRITERIA OF 25 GPM FOR        |
| IDENTIFIED LEAKAGE AND THE MAXIMUM PLANT VENT RELEASE RATE WAS APPROXIMATELY |
| 835 MICROCURIES/SEC.  PLANT CONDITIONS ARE STABLE AND AN INVESTIGATION IS    |
| ONGOING.  THERE IS NO RELEASE AT THIS TIME AND THE APPROXIMATE RELEASE RATE  |
| WAS ABOUT 1% OF LIMITS.                                                      |
