| NRC BULLETIN 91-01 RESPONSE, 4-HOUR NOTIFICATION - LOSS OF MODERATION  AND   |
| MASS CONTROL                                                                 |
|                                                                              |
| On 12/09/98 at 1820 EST, Plant Operations and Nuclear Criticality Safety     |
| personnel  identified that a Nuclear Criticality Safety Analysis (NCSA)      |
| requirement could not be maintained in the X-326 building.  NCSA-326_13.A06  |
| administrative control requirement #8 states, in part, "Within 8 hours after |
| cascade equipment shutdown (motor turned off) and with the system at a UF6   |
| negative, the system shall be pressurized with dry air or N2 buffer at 14    |
| psia or greater."  This cannot be accomplished for cell 25-7-2 due to the    |
| primary containment that was breached during a fire that occurred in the     |
| cell.  Also, cell 25-7-6 leaked to atmosphere prior to being buffered due to |
| possible failure of an expansion joint.  Each cell contains 12 converters,   |
| and the holes in the converters caused a loss of moderation control and loss |
| of mass control.  The holes in the converters can let air intrude into the   |
| converters which can cause a buildup of moisture in the converters.          |
|                                                                              |
| The certificate holder has isolated both cells and isolated the water system |
| going to both cells including the sprinkler system (fire protection system). |
| Visual inspection of a limited number of the converters and a review of      |
| typical cell inventory data reveals that the cells do not contain a critical |
| mass in them.  Also, the cells mentioned above have been isolated.           |
|                                                                              |
| The certificate holder notified the NRC Resident Inspector, the local        |
| Department of Energy (DOE) representative, and the state of Ohio.  The       |
| certificate holder also issued a press release.                              |
|                                                                              |

| This event notification is being updated to change the previous report of a  |
| 4-hour notification (loss of moderation and mass control) to a 24-hour       |
| notification due to current NDA scans that identify the deposits in          |
| converter 25-7-2 to be less than the calculated safe mass.  Loss of a single |
| contingency (moderation) remains a 24-hour notification.  Also, it was       |
| determined that the previous report of converter 25-7-6 leaking to           |
| atmosphere (potential loss of moderation control) was incorrect.  There was  |
| no failure in converter 25-7-6 that breached containment.                    |
|                                                                              |
| The certificate holder notified the NRC Resident Inspector, the local DOE    |
| representative, and the state of Ohio.  The NRC Operations Officer notified  |
| the R3DO (Mark Ring), NMSS EO (Wayne Hodges), and AEOD IRD (Joe Giitter).    |
|                                                                              |

| *** UPDATE ON 12/11/98 @ 1644 FROM SISLER TO GOULD ***                       |
|                                                                              |
| UPON FURTHER REVIEW OF THIS EVENT,  IT HAS BEEN DETERMINED THAT THE EVENT    |
| MEETS THE REPORTING CRITERIA  FOR OPERATIONS THAT COMPLY WITH THE DOUBLE     |
| CONTINGENCY PRINCIPLE WHERE MODERATION IS USED AS THE PRIMARY CRITICALITY    |
| CONTROL.  THE REPORTING CRITERIA CHANGED WHEN THE DEPOSIT IN 25-7-2 WAS      |
| DETERMINED TO BE LESS THAN A SAFE MASS.  NCSA-326_013.A06 ADMINISTRATIVE     |
| CONTROL REQUIREMENT NO. 8 WAS NOT RE-ESTABLISHED WITHIN 4 HOURS AFTER THE    |
| INITIAL OBSERVATION OF THE EVENT.  THAT CONTROL IS MODERATION, AND THE       |
| MODERATION CONTROL HAS YET TO BE RE-ESTABLISHED.  MASS CONTROL WAS           |
| MAINTAINED THROUGH THE EVENT.  THIS MEETS THE BULLETIN 91-01 4-HOUR          |
| REPORTING CRITERIA.  THIS EVENT SHOULD NOT HAVE BEEN DOWN GRADED TO A        |
| 24-HOUR REPORT.                                                              |
|                                                                              |

| * * * UPDATE ON 3/25/99 AT 2111 EST BY RICK LARSON TO FANGIE JONES * * *     |
|                                                                              |
| Upon further review of this event, it has been determined that the event     |
| constituted only a single contingency in that the operation of the cascade   |
| is considered a single contingency in accordance with SAR 5.2.  Thus, the    |
| report of a double contingency loss was incorrect and the only contingency   |
| lost was moderation.  The report would still be an initial 4 hour            |
| notification requirement.                                                    |

| Portsmouth personnel notified the NRC Resident Inspector and the DOE site    |

| TSR allowed one of two smoke detectors to be inoperable during withdrawal    |
| operations when both smoke detectors have to be operable during withdrawal   |
| operations.                                                                  |
|                                                                              |
| On March 10, 1999, Operations personnel identified a deficiency in a TSR     |
| requirement for the Pigtail line Isolation System at ERP (extended range     |
| product), LAW (low assay withdrawal), and TAILS, (TSR 2.5.3.4). The TSR      |
| required action allowed continued withdrawal operations if one (1) smoke     |
| detector was inoperable.  The Pigtail Line Isolation System requires two (2) |
| Pyrotronics Smoke Detectors to actuate for the isolation valve to close.     |
| Operation personnel initiated a Compensatory Action (CA-99-009) for this     |
| anomaly to isolate the withdrawal cylinder and manifold per TSR 2.5.3.4b if  |
| one smoke detector is declared inoperable.                                   |
|                                                                              |
| Initially there was no evidence that the Pigtail Line Isolation System had   |
| been allowed to operate any applicable mode (modes II or III) with one or    |
| more inoperable smoke head.  As a follow up investigation to this            |
| deficiency, a search of the BPS system (problem report database) was         |
| conducted.  This search identified that on July 8, 1998, a Pyrotronic smoke  |
| head at the Law IA withdrawal position had been declared inoperable and      |
| cylinder filling operations had been allowed to continue.                    |
|                                                                              |
| This event is reportable due to a Safety System required by the TSR not      |
| being available or operable and no redundant equipment was available to      |
| perform the required safety function.                                        |
|                                                                              |

| ESF ACTUATION RESULTING IN ISOLATION OF A DIVISION 2 VALVE                   |
|                                                                              |
| "An invalid ESF actuation resulted in the isolation of Division 2 primary    |
| containment isolation valve RHSAOV62 SUPPRESSION POOL CLEANUP (SPC) SYSTEM   |
| SUCTION.                                                                     |
|                                                                              |
| "During outage preparation activities in the Reactor Building Dryer storage  |
| pool, level in the pool was inadvertently lowered approximately three and    |
| one-half inches, resulting in a non-ESF isolation signal from the division 2 |
| dryer pool level indicator.  The level change was caused by a siphon effect  |
| that was created through a vacuum hose being staged between the Dryer Pool   |
| and Refueling Cavity for pool cleanup.                                       |
|                                                                              |
| "The lowering level was terminated upon identification and all systems       |
| responded as designed."                                                      |

| The siphon action was started during 'bump' testing of the vacuuming system  |
| during setup due to the differences in pool levels of about one foot.  Work  |
| has been terminated until an investigation is completed and necessary        |
| changes to the work are made.                                                |
|                                                                              |
