| REACTOR CORE ISOLATION COOLING (RCIC) SYSTEM MAY NOT BE PROTECTED BY STEAM |
| LEAK DETECTION CIRCUITRY. |
| |
| A LICENSEE ENGINEERING REVIEW IDENTIFIED A SECTION OF RCIC SYSTEM PIPING |
| WHICH MAY NOT BE PROTECTED BY THE STEAM LEAK DETECTION CIRCUITRY. |
| SPECIFICALLY, THE STEAM SUPPLY ISOLATION SIGNAL MAY NOT ISOLATE A POSTULATED |
| CRACKED STEAM SUPPLY LINE PRIOR TO CRACK PROPAGATION AS IN THE DESIGN INTENT |
| OF THE STEAM LEAK DETECTION SYSTEM. THE LICENSEE IS CONTINUING WITH ITS |
| INVESTIGATION. THE RCIC SYSTEM WAS NOT DECLARED INOPERABLE AND THE LICENSEE |
| HAS NOT ENTERED ANY LCO ACTION STATEMENTS. |
| |
| THE NRC RESIDENT INSPECTOR WAS NOTIFIED. |

| |
| "A review of plant design and licensing basis documentation has confirmed |
| that the design and licensing basis requirements for the SLD system as |
| defined in the UFSAR have not been properly maintained. It is therefore not |
| clear that the ability to detect and isolate a leak prior to the leak |
| propagating to a break in this section of pipe is in fact a design basis |
| requirement. |
| |
| "LER 99-013 identified the condition where the SLD system was outside the |
| design basis of the plant because the system could not reliably detect a 7 |
| GPM leak (but could detect a 25 GPM leak). The review of plant design and |
| licensing basis documentation discussed above has identified the need to |
| revise corrective actions identified in LER 99-013 to include a more |
| comprehensive redefinition of the design and licensing basis requirements |
| for the SLD system. The event reported in 10 CFR 50.72 notification log |
| number 37016 is therefore an extent of the condition reported in LER 99-013 |
| and will therefore be discussed in the revision to LER 99-013. |
| |
| "On this basis 10 CFR 5072 notification log number 37016 is redundant to the |
| condition reported in LER 99-013 and 10 CFR 50.72 notification log number |
| 37016 is therefore retracted." |
| |
| The licensee notified the NRC Resident Inspector. The R1DO (Robert Summers) |
| was notified. |

EVENT TEXT
+------------------------------------------------------------------------------+
| POTENTIAL PERSONNEL OVEREXPOSURE |
| |
| A technician opened a "package" on the loading dock to check the contents |
| after an apparent miscommunication. The package contained 1650 curies of |
| Co-60 in a shielded container. The technician received an undetermined dose |
| to the head and shoulder areas of the body, possibly in excess of 5 rem. |
| The dose will be determined but there is a good chance that it will be less |
| than 5 rem. Even after removal of the outer plug there was still 1.125 |
| inches of tungsten shielding. |
| |
| The Massachusetts Radiation Control Program plans to go to the site and |
| conduct an investigation. |

| PLANT SHUTDOWN REQUIRED BY TECH SPEC 3.0.3 DUE TO FAILED VALVE TESTING |
| |
| The licensee was conducting Instrument and Control testing under DB-MI-03211 |
| which failed to produce the expected response for solenoid SP6A2 on valve |
| SP6A, Steam Generator Main Feedwater Valve. The problem is with the |
| solenoid or associated limit switch. Due to a lack of specific Technical |
| Specification guidance, 3.0.3 has been entered which requires the plant to |
| initiate action to place the plant in a mode in which the specification does |
| not apply. It is expected that the plant will be able to repair and test |
| prior to a full plant shutdown. |
| |
| The licensee notified the NRC Resident Inspector. |
| |
| * * * UPDATE AT 1710 EST ON 6/19/00 BY CRAIG GILLIG TO FANGIE JONES * * * |
| |
| The licensee determined the problem was with the limit switch, has exited |
| the tech spec required shutdown, and is returning to full power from 96%. |
| |
| The licensee intends to notify the NRC Resident Inspector. The R3DO (Roger |
| Lanksbury) has been notified. |
