Each OPRM channel contains 18 to 33 OPRM cells (depending | | upon plant size). Each OPRM cell signal is summed from three to four | | closely spaced Local Power Range Monitor (LPRM) signals. Each OPRM cell | | signal is processed through the Option Ill detection algorithms to determine | | when a trip is required. Trip of one OPRM cell causes its OPRM channel to | | trip, and when sufficient OPRM channels trip (one-out-of-two taken twice, or | | two-out-of-four), a reactor scram is initiated to terminate the | | oscillation. | | | | "An OPRM trip is enabled for plant operation within the OPRM Armed Region as | | defined on the power/flow map. The Armed Region extends from natural | | circulation to 60% of rated core flow. The licensing basis for the OPRM is | | to detect all expected oscillations within the OPRM Armed Region, and | | initiate a reactor trip to suppress the oscillation and provide Minimum | | Critical Power Limit (MCPR) safety limit protection. | | | | "GE LTR NEDO-31960-A, Supplement 1, 'BWR Owners' Group Long - Term Stability | | Solutions Licensing Methodology (Supplement 1),' November 1995, describes | | the Option III detection algorithms. The Period Based Detection Algorithm | | (PBDA) provides licensing basis MCPR safety limit protection. Other | | algorithms provide defense-in-depth protection. The PBDA includes two | | parameters called Tmin and Tmax. The PBDA will not evaluate oscillations if | | the period is less than Tmin or greater than Tmax because these would not | | be indicative of an expected coupled neutronic/thermal - hydraulic | | instability. The LTR specifies that 'typical' Tmin values are in the | | range of 1.0 to 1.4 seconds and 'typical' Tmax values are in the range of | | 3.0 to 3.5 seconds. | | | | "The expected period of a coupled neutronic/thermal-hydraulic instability | | depends upon the fluid transit time through the core, and therefore depends | | upon core flow rate. This has been demonstrated in reactor operation and is | | predicted by GE computer models. At high core flow, the expected | | oscillation period is shorter. At low core flow rate, the expected | | oscillation period is longer. The intent of the OPRM is that Tmin and Tmax | | provide a wide range with adequate margin to the expected oscillation period | | for operation within the OPRM Armed Region so that all expected coupled | | neutronic/thermal-hydraulic instabilities will be detected by the PBDA." | +------------------------------------------------------------------------------+ +------------------------------------------------------------------------------+ |Power Reactor |Event Number: 39393 | +------------------------------------------------------------------------------+ +------------------------------------------------------------------------------+ | FACILITY: ARKANSAS NUCLEAR REGION: 4 |NOTIFICATION DATE: 11/22/2002| | UNIT: [1] [2] [] STATE: AR |NOTIFICATION TIME: 15:10[EST]| | RXTYPE: [1] B&W-L-LP,[2] CE |EVENT DATE: 11/22/2002| +------------------------------------------------+EVENT TIME: 08:56[CST]| | NRC NOTIFIED BY: HATHCOTE |LAST UPDATE DATE: 11/22/2002| | HQ OPS OFFICER: CHAUNCEY GOULD +-----------------------------+ +------------------------------------------------+PERSON ORGANIZATION | |EMERGENCY CLASS: NON EMERGENCY |DALE POWERS R4 | |10 CFR SECTION: | | |DDDD 73.71(b)(1) SAFEGUARDS REPORTS | | | | | | | | | | | +-----+----------+-------+--------+-----------------+--------+-----------------+ |UNIT |SCRAM CODE|RX CRIT|INIT PWR| INIT RX MODE |CURR PWR| CURR RX MODE | +-----+----------+-------+--------+-----------------+--------+-----------------+ |1 N Y 100 Power Operation |100 Power Operation | |2 N Y 100 Power Operation |100 Power Operation | | | | +------------------------------------------------------------------------------+ EVENT TEXT +------------------------------------------------------------------------------+ | SECURITY REPORT | | | | Unattended security weapon, compensatory measures put in place upon | | discovery. | | | | The NRC Resident Inspector was notified | | | | Contact HOO for additional details. | +------------------------------------------------------------------------------+ +------------------------------------------------------------------------------+ |Other Nuclear Material |Event Number: 39394 | +------------------------------------------------------------------------------+ +------------------------------------------------------------------------------+ | REP ORG: UNITED STATES ARMY -ABERDEEN |NOTIFICATION DATE: 11/22/2002| |LICENSEE: UNITED STATES ARMY |NOTIFICATION TIME: 15:31[EST]| | CITY: ABERDEEN REGION: 1 |EVENT DATE: 10/31/2002| | COUNTY: STATE: MD |EVENT TIME: [EST]| |LICENSE#: 91-30563-01 AGREEMENT: Y |LAST UPDATE DATE: 11/22/2002| | DOCKET: |+----------------------------+ | |PERSON ORGANIZATION | | |MOHAMED SHANBAKY R1 | | |DAVID AYRES R2 | +------------------------------------------------+FRED BROWN NMSS | | NRC NOTIFIED BY: JOYCE KUYKENDALL | | | HQ OPS OFFICER: JOHN MacKINNON | | +------------------------------------------------+ | |EMERGENCY CLASS: NON EMERGENCY | | |10 CFR SECTION: | | |BLO1 20.2201(a)(1)(i) LOST/STOLEN LNM>1000X | | | | | | | | | | | | | | +------------------------------------------------------------------------------+ EVENT TEXT +------------------------------------------------------------------------------+ | MISSING CHEMICAL AGENT DETECTOR CONTAINING 30 MILLICURIES OF NICKEL-63 | | | | During a conversation in a training exercise on October 31, 2002, the | | Radiation Safety Officer at Fort Bragg, NC learned that a Unit had lost a | | GID-3 Chemical Agent Detector, containing 30 millicuries of Nickel-63, | | during a training exercise back in Oct/Nov of 2001.

During inspection of the High | | Pressure Core Spray (HPCS) 2VY02A area cooler, missing sheet metal screws | | were discovered. This could have prevented the High Pressure Core Spray | | System (HPCS), a single train safety system, from performing its design | | function during a seismic event. This also made the Division 3 Diesel | | Generator inoperable. This is reportable as an 8 hour ENS notification. | | | | "The required actions of Technical Specification (TS) 3.5.1 were entered on | | 11/22/02 at 1650 when the system was made inoperable. TS 3.8.1 does not | | require Division 3 Diesel Generator operability if HPCS is declared | | inoperable. Preparations to replace the missing sheet metal screws are in | | progress. All other Emergency Core Cooling Systems are operable at this | | time. An extent of condition review will be performed on all divisions for | | both units." | | | | The NRC Resident Inspector was notified of this event by the licensee. | | | | | | * * * UPDATE ON 11/23/02 @ 1333 BY CLARK TO GOULD * * * | | | | "Subsequent to ENS notification EN #39399, repairs were affected to the HPCS | | area cooler (2VY02A) and the system was returned to operable. An extent of | | condition inspection was performed on the remaining Unit 1 and Unit 2 | | divisional area coolers. During these inspections it was discovered that | | the Unit 1, Division 2 area cooler (1VY03A) was also missing several sheet | | metal screws. The system was removed from service, repaired and returned | | to operable. No problems were discovered on either of the two remaining | | Unit 1 divisional area coolers. | | | | During inspection on Unit 2, the Division 2 area cooler (2VY03A) was missing | | all of its sheet metal screws. At the time of discovery of the Division 2 | | inoperability, the HPCS (Division 3) area cooler had already been repaired | | and declared operable. It was determined however, that at some point both | | the HPCS (Division 3) and Division 2 Emergency Core Cooling System (ECCS) | | injection subsystems were under these conditions simultaneously. Per | | Technical Specification (TS) 3.5.1 Bases when this combination of ECCS | | subsystems are inoperable, the plant is in a condition outside of the design | | basis. | | | | Investigation of equipment and maintenance history will be performed to | | determine if any additional periods existed with multiple divisions under | | these conditions simultaneously. At this time all divisional area coolers | | on both Units have been inspected.
