| -HIGH PRESSURE COOLANT INJECTION SYSTEM INOPERABLE DUE TO SYSTEM FLOW |
| OSCILLATIONS- |
| |
| WHILE TESTING THE HIGH PRESSURE COOLANT INJECTION (HPCI) SYSTEM AT 25% |
| POWER, THE LICENSEE OBSERVED SYSTEM FLOW OSCILLATIONS. THE LICENSEE REMOVED |
| THE HPCI TURBINE FROM SERVICE TO DETERMINE THE CAUSE AND TAKE CORRECTIVE |
| ACTIONS AND DECLARED THE HPCI SYSTEM INOPERABLE. TECH SPEC LCO A/S |
| 3.5.C.1.a REQUIRES THE LICENSEE TO RESTORE THE HPCI SYSTEM TO OPERABLE |
| STATUS WITHIN 7 DAYS. |
| |
| THE LICENSEE INFORMED THE NRC RESIDENT INSPECTOR. |
| |
| * * * UPDATE AT 1332 ON 10/21/99 BY BOB STEIGERWELD TO JOLLIFFE * * * |
| |
| This notification retracts an earlier report made at 1916 on 12/21/98 per |
| 10CFR50.72(b)(2)(iii)(B) and (D), due to observed flow oscillations during |
| HPCI System testing. On 12/23/98, the licensee determined that the flow |
| oscillation did not affect the operability of the HPCI System and this event |
| notification should have been retracted at that time. |
| |
| During HPCI System testing following a refueling outage, the HPCI System was |
| declared inoperable due to observed flow spiking indication on start up of |
| the system. Upon further investigation, the observed oscillations were |
| attributed to spiking on system startup due to either air in the flow |
| transmitter or electronic noise providing a false momentary indication. In |
| either case, it was demonstrated that the HPCI System was not affected by |
| the momentary spiking indication and the system was able to perform its |
| function and was determined to be operable. Therefore, this event |
| notification is being retracted. |
| |
| The licensee notified the NRC Resident Inspector. |
| |
| The NRC Operations Officer notified the R1DO Bill Cook. |

| EMERGENCY SERVICE WATER SYSTEM DEGRADATION (ONLY ONE OF FOUR PUMPS |
| OPERABLE) |
| |
| The following text is a portion of a facsimile received from the licensee: |
| |
| "On 08/26/99, Susquehanna Unit 1 and Unit 2 were operating at 100% power |
| with the 'B' loop of emergency service water [(ESW)] out of service for |
| scheduled maintenance. During testing on the ESW system, with all ESW pumps |
| in service, it was identified that the 'C' and 'D' ESW pumps' discharge |
| check valves were closed. The ESW flow surveillance was performed, and the |
| 'C' and 'D' ESW pumps failed to achieve the required flow and were declared |
| inoperable. Concurrently, the 'B' loop of ESW was returned to service. |
| During the time the 'B' ESW loop was inoperable, the 'A' ESW pump was the |
| only one operable ESW pump. This constitutes a serious degradation of the |
| plant in that it is a condition which is outside of design basis and, |
| therefore, reportable under 10 CFR 50.72(b)(1)(ii) requiring a 1-hour ENS |
| notification." |
| |
| The licensee notified the NRC resident inspector. |
| |
| * * * UPDATE 1453EDT ON 9/3/99 FROM GRANT FERNSLER TO S. SANDIN * * * |
| |
| "This Notification is a retraction of a previous ENS Notification made |
| 8/27/99 (Event # 36079)." |
| |
| "Subsequent evaluation by Engineering has concluded that the plant had at |
| least two Emergency Service |
| Water pumps capable of performing their specified safety function at all |
| times. As such, the plant was not |
| in a condition outside of its design basis and the report previously made |
| pursuant to 10CFR50.72(b)(1)(ii) |
| is hereby retracted." |
| |
| The licensee informed the NRC Resident Inspector. Notified R1DO(Rogge). |
| |
| * * *UPDATE 0316EDT ON 09/23/99 FROM MIKE PEAL TAKEN BY MACKINNON* * * |
| |
| The licensee is Retracting the Retraction they called in on 09/03/99 at |
| 1453EDT. |
| |
| "On 09/22/99 at 2230, an Engineering evaluation concluded that the |
| operability determination associated with the above stated event was not |
| adequate, specifically relating to the potential for pump interaction to |
| create low flow conditions. " |
| |
| "The Engineering evaluation was being performed in response to an anomaly |
| identified on 09/20/99 during the run of 'D' Diesel Generator. During the |
| preparation of the operability statement for the 09/20/99 anomaly, |
| engineering personnel realized that incorrect assumptions were used in the |
| previous operability statement. The 'C' and 'D' ESW pumps were declared |
| inoperable at 2230 on 09/22/99. Evaluation continues to determine if other |
| combinations of equipment out of service times result in additional |
| reportable conditions." R1DO (Bob Summers) notified. |
| |
| The NRC Resident Inspector will be notified of the Retraction to the |
| Retraction of this event by the licensee. |
| |
| * * * UPDATE AT 1325 ON 10/21/99 BY MIKE PEAL TO JOLLIFFE * * * |
| |
| Based on additional evaluations by Licensee Engineering, Operations and |
| Licensing spanning the time frame of 06/03/99 to 09/28/99, the licensee |
| concluded that the plant had at least one Emergency Service Water Pump per |
| loop capable of performing its specified safety function at all times. As |
| such, the plant was not in a condition outside of its design basis, was not |
| in an unanalyzed condition, and there was no loss of safety function. The |
| report previously made pursuant to 10CFR50.72(b)(1)(ii) on 09/23/99 is |
| hereby retracted. |

| 24 HOUR 91-01 BULLETIN RESPONSE |
| |
| ON 10/20/99 AT 1030 HOURS, A NUCLEAR CRITICALITY SAFETY ANALYSIS (NCSA) |
| NONCOMPLIANCE WAS IDENTIFIED IN THE X-330 PROCESS BUILDING. THIS |
| NONCOMPLIANCE WAS DISCOVERED WHILE REVIEWING OBSERVATIONS FOUND DURING A |
| WALKDOWN OF IMPLEMENTED NCSAs. |
| |
| AT COLUMN C-53 ON THE CELL FLOOR OF X-330, A DRIP PAN CONNECTED TO A PAIR OF |
| LUBE OIL STRAINERS DID NOT MEET THE REQUIREMENTS OF NCSA-PLANT054 FOR LUBE |
| OIL SYSTEMS. NCSA-PLANT054 REQUIRES ALL LUBE OIL LEAK COLLECTION CONTAINERS |
| IN AREAS WHERE SIGNIFICANT UF6 RELEASES ARE CONSIDERED CREDIBLE, MEET |
| CERTAIN SIZE RESTRICTIONS. IN X-330, THE MAXIMUM ALLOWED DEPTH OF A LUBE OIL |
| DRIP PAN ON THE CELL FLOOR IS 3.6 INCHES. THE DRIP PAN FOUND WAS 5.76 INCHES |
| DEEP. THIS VIOLATES THE CONTAINER SIZE REQUIREMENT OF THE NCSA. THE DRIP PAN |
| CONTAINED APPROXIMATELY 25 QUARTS OF OIL AT TIME OF DISCOVERY. THERE WAS NO |
| EVIDENCE OF ANY UF6 RELEASES IN THE AREA. |
| |
| THE CONTAINER SIZE LIMIT WAS EXCEEDED RESULTING IN THE LOSS OF GEOMETRY. THE |
| OTHER CONTROL OF THE DOUBLE CONTINGENCY PRINCIPLE (CONCENTRATION) WAS |
| MAINTAINED THROUGHOUT THIS EVENT. |

| 24 HOUR 91-01 BULLETIN RESPONSE |
| |
| On 10/21/ 1999 at 1500 hrs the Plant Shift Superintendent(PSS) was notified |
| that a Nuclear Criticality Safety Approval (NCSA) requirement was not being |
| performed in the X-710 ES&H Analytical Labs. NCS Engineering, while |
| performing an NCS Self Assessment, noticed an operation where samples were |
| brought to a staging area "INSIDE" a room when they were logged in and |
| verified. (NCSA-0710_025.AOO) |
| |
| Requirement #1 of NCSA-071_25.AOO states in part; Samples in any room |
| enriched to 1% or greater U-235, will be limited to one group of 30g U-235 |
| per room. This will be ensured by maintaining a room inventory log of U-235 |
| mass in labeled containers. Each log entry will consist of the U-235 mass |
| value plus analytical uncertainty and will be: |
| |
| a. made by a knowledgeable person "PRIOR" to bringing the samples into the |
| room, and |
| b. verified by a second knowledgeable person "PRIOR" to bringing the samples |
| into the room. |
| |
| At the direction of the Plant Shift Superintendent the requirements for an |
| NCS anomalous condition were initiated and the area baundaried off. |
| |
| The safety significance of the event is very low. The U-235 mass in material |
| is being maintained less than 30 grams as required. This is more than a |
| factor of 10 less than the always safe mass of 350 grams U-235. The samples |
| were brought to a staging area inside the room where they were logged in and |
| verified. After logging and verifying the samples were moved to the |
| operational area of the room, where they could interact with other materials |
| in the room. |
| |
| Samples in any room enriched to 1% or greater U-235, with a concentration |
| greater or equal to 500 ppm U-235, shall be limited to one group of 30 g |
| U-235 per room. This shall be ensured by maintaining a room inventory log of |
| U-235 mass in labeled containers. Each log entry shall consist of the U-235 |
| mass value plus analytical uncertainty and shall be: |
| |
| Mass is the only parameter controlled |
| |
| The actual amount of material In the room is less than 30 grams U-235, at an |
| enrichment of less than or equal to 100%. This value is obtained from sample |
| data that was logged after the material was brought Into the room. This is |
| approximately 4% of the worst case critical mass. |
| |
| Verbatim compliance with both mass controls was lost because the material |
| was supposed to be checked and verified prior to bringing the material into |
| the room. The samples were brought to a staging area inside the room where |
| they were logged in and verified. After logging and verifying the samples |
| were moved to the operational area of the room, where they could interact |
| with other materials in the room. |
| |
| THERE WAS NO LOSS OF HAZARDOUS/RADIOACTIVE MATERIAL OR |
| RADIOACTIVE/RADIOLOGICAL CONTAMINATION EXPOSURE AS A RESULT OF THIS EVENT. |
| |
| The Resident Inspector was notified and the DOE Representative will be |
| notified. |
