| ONE HIGH HEAD SAFETY INJECTION LINE DETERMINED NOT TO HAVE FLOW DURING |
| TESTING |
| |
| "During performance of the 18 month high head charging valve throttle test, |
| it was discovered that the #21 high head cold leg injection line did not |
| pass flow until the other three lines for high head cold leg injection were |
| closed. At that point, an audible indication was heard and flow was |
| observed through the #21 cold leg. All cold leg injection flows were |
| subsequently balanced. The cause of this is under investigation and will be |
| resolved prior to Mode 4." |
| |
| The licensee notified the NRC Resident Inspector and will be notifying the |
| local government agencies. |
| |
| * * * UPDATE AT 1212 ON 6/1/99 BY SIMPSON TAKEN BY WEAVER * * * |
| |
| On 5/3/99, Salem Unit 2 reported an event concerning a safety injection |
| system cold leg injection line which appeared to not pass flow during the |
| performance in an 18 month surveillance test for flow balancing. The |
| discrepancy appeared to be due to a stuck check valve. At the time of the |
| event it was not known how long the condition had existed thus a 50.72 call |
| was made. The valve in question (21SJ17) was subsequently physically |
| removed from the system and inspected. No failure mode was determined. No |
| evidence was found that the valve had been inoperable for any length of |
| time. These valves do not have a history of negative performance in this |
| application. A review of' industry data did not identify any similar |
| sticking problems, generally the failure reported concerned leakage. |
| Therefore, the guidance of NUREG 1022 applies. This guidance states that |
| the out of service time is calculated using the time of discovery unless |
| there is firm evidence based on a review of relevant information (e.g. the |
| equipment history and cause of failure) to believe the discrepancy existed |
| previously. Based on the time of discovery being the event date, this |
| event is not reportable because the requirements of the Technical |
| Specifications were being met for the current mode of operations and the |
| event is bounded by current design. Further review of the design bases is |
| underway to confirm assumptions. |
| |
| The licensee informed the NRC resident inspector. The Operations Center |
| informed R1DO (Conte). |

| INFORMATION REPORT RECEIVED FROM AN AGREEMENT STATE INVOLVING AN UNPLANNED |
| CONTAMINATION EVENT |
| |
| "Description of Event : In accordance with Rule .03(14)(b)2. of the Rules |
| and Regulations for Radioactive Material, Joseph Rodgers, Deputy RSO, ((770) |
| 271-0233) notified the Department of an unplanned contamination event. |
| While transporting a shielded 100 milliliter volumetric flask containing 24 |
| Curies of purified liquid Pd 103 (cyclotron produced) the transport cart |
| struck an object in the lab and the flask toppled out of the shield onto the |
| floor. The Chemist immediately exited the area and notified health physics. |
| Steps were immediately implemented to: minimize any exposure; prevent the |
| spread of contamination; and initiate timely gross decontamination. Access |
| to the room remains restricted and monitoring will continue with |
| decontamination planned for the end of next week after the radiation levels |
| are reduced by decay of the Palladium. Emergency processing of the film |
| badges for the three involved employees was initiated with the following |
| range of exposures reported for whole body: DDE 55 mrem to 277 mrem; LDE 61 |
| mrem to 326 mrem; SDE 65 mrem to 355 mrem; and for extremities: SDE 170 mrem |
| to 4040 mrem. Nasal swabs of the affected employees were negative. Results |
| from a fixed air sampler, whose intake is directly above the area of the |
| spill, indicated the 10 CFR Part 20 Appendix B values for inhalation were |
| not exceeded. No radioactive materials were released outside the restricted |
| area. Representatives of the Radiation Control Program visited the site on |
| 5/27/99. The Licensee will submit a written report within 30 days, implement |
| short term corrective actions and resume operation in this facility in early |
| June, 1999." |

| 24-HOUR NRC BULLETIN 91-01 REPORT INVOLVING LOSS OF CRITICALITY CONTROL |
| |
| "On 5/28/99 at 0945 hrs operations personnel discovered a 5" polybottle |
| containing uranium bearing material leaking solution from around the top of |
| the container. The lid was found to be loose on the polybottle. An onsight |
| NCS Engineer responded to the scene and assessed the condition to be a loss |
| of control such that only one double contingency control remained in place. |
| NCSA-PLANT006 requirement #2 and requirement #12 state in part: lids provide |
| a barrier against spilling the material and the container is not moved while |
| the lid is loose. |
| |
| "THERE WAS NO RADIOACTIVE/RADIOLOGICAL CONTAMINATION EXPOSURE AS A RESULT OF |
| THIS EVENT. |
| |
| "SAFETY SIGNIFICANCE OF EVENTS: |
| |
| "Safety Significance is low due to the small amount of material that leaked |
| (10-20 ml) and the fact that the container was upright and spaced. |
| |
| "POTENTIAL CRITICALITY PATHWAYS INVOLVED (BRIEF SCENARIO[S] OF HOW |
| CRITICALITY COULD OCCUR): |
| |
| "Sufficient leakage could have accumulated in an unfavorable geometry, i.e., |
| a building drain. With a high enrichment to create a criticality. |
| |
| "CONTROLLED PARAMETERS (MASS, MODERATION, GEOMETRY, CONCENTRATION, ETC.): |
| |
| "Geometry and spacing are the controlled parameters. |
| |
| "ESTIMATED AMOUNT, ENRICHMENT, FORM OF LICENSED MATERIAL (INCLUDE PROCESS |
| LIMIT AND % WORST CASE OF CRITICAL MASS): |
| |
| "Amount of material is 10-20 ml of UF4 contaminated oil at 10.77% |
| enrichment. |
| |
| "NUCLEAR CRITICALITY SAFETY CONTROL(S) OR CONTROL SYSTEM(S) AND DESCRIPTION |
| OF THE FAILURES OR DEFICIENCIES: |
| |
| "The geometry of the container was deficient when the lid was left loose |
| enough to allow material to slosh inside and seep through the threads. |
| |
| "CORRECTIVE ACTIONS TO RESTORE SAFETY SYSTEM AND WHEN EACH WAS IMPLEMENTED: |
| |
| "The material was cleaned up and some material decanted into another |
| polybottle at approx. 1230 hrs. Remaining storage areas were policed for |
| polybottles with loose lids, none were found." |
| |
| Operations informed the DOE Site Representative and the NRC Resident |

| 24-HOUR NRC BULLETIN 91-01 REPORT INVOLVING LOSS OF CRITICALITY CONTROL |
| |
| "On Friday, May 28, 1999 at 0810 hours, Operating personnel discovered that |
| a Nuclear Criticality Safety Approval (NCSA) Requirement was not being |
| maintained in the X-705 Decontamination Facility. NCSA-PLANT 053.A01 titled |
| 'Uranium Analysis and Sampling' requirement #8 states in part, Samples may |
| be grouped together but groups shall be spaced a minimum of two feet edge-to |
| edge. Six 250 ml sample bottles containing uranium bearing material were |
| found within 16 inches of a polybottle. |
| |
| "THERE WAS NO LOSS OF HAZARDOUS/RADIOACTIVE MATERIAL OR |
| RADIOACTIVE/RADIOLOGICAL CONTAMINATION EXPOSURE AS A RESULT OF THIS EVENT. |
| |
| "SAFETY SIGNIFICANCE OF EVENTS: |
| |
| "The Safety Significance is low since all the material is less than 10% |
| enrichment, the sample batch is less than 2 liters, and some spacing was |
| provided. |
| |
| "POTENTIAL CRITICALITY PATHWAYS INVOLVED (BRIEF SCENARIO[S] OF HOW |
| CRITICALITY COULD OCCUR): |
| |
| "Numerous spacing violations of highly concentrated uranium solutions can |
| lead to a criticality in the absence of volume and/or geometry controls. |
| |
| "CONTROLLED PARAMETERS (MASS, MODERATION, GEOMETRY, CONCENTRATION, ETC.): |
| |
| "Volume arid Interactions were the controlled parameters. Interactions was |
| lost. |
| |
| "ESTIMATED AMOUNT, ENRICHMENT, FORM OF LICENSED MATERIAL (INCLUDE PROCESS |
| LIMIT AND % WORST CASE OF CRITICAL MASS): |
| |
| "Six 250 ml sample bottles were involved containing various uranium bearing |
| solutions of uranyl nitrate and/or uranyl fluoride. Enrichment is not |
| expected to be greater than 10%. |
| |
| "NUCLEAR CRITICALITY SAFETY CONTROL(S) OR CONTROL SYSTEM(S) AND DESCRIPTION |
| OF THE FAILURES OR DEFICIENCIES: |
| |
| "The applicable controls are volume and spacing. Spacing between the samples |
| and the polybottle was lost. |

| The following text is a portion of a facsimile received from the licensee: |
| |
| "On 05/30/99 at approximately 1210 PDT, a male green sea turtle was removed |
| from the Diablo Canyon Power Plant intake structure. The sea turtle had |
| entered the intake structure by swimming under the apron wall and surfacing |
| outside of the bar racks. The sea turtle was transported by boat to a |
| release point approximately 0.5 miles due west of the intake structure. It |
| was observed to swim strongly away from the release point. The turtle's |
| shell length was measured at 69 cm, and its weight was estimated to be 50-75 |
| lbs. The turtle appeared to be in good health with no visible injuries with |
| the exception of some scrapes on the rear of its shell." |
| |
| "The Diablo Canyon Power Plant Environmental Services Department has |
| notified the National Marine Fisheries Service and the California Department |
| of Fish and Game of the capture and subsequent release of the sea turtle, |
| which is protected under the Endangered Species Act." |

| BYPRODUCT MATERIAL SPILLED IN A RESTRICTED AREA |
| |
| A backhoe accidentally broke a pipeline from the central plant to the waste |
| disposal well causing a spill of about 4000 gallons of fluid. The fluid |
| contained approximately 15-20 ppm U3O8. The pipeline was not in use at the |
| time of the break so only the fluid in the pipe drained into the ditch that |
| the backhoe was digging. The fluid has been pumped back into the process |
| facility and any residual solids have been cleaned up. The accident |
| occurred within the confines of the site. |
