| AGREEMENT STATE REPORT |
| |
| This is notification of an event in Washington state as investigated by the |
| WA Department of Health, Division of Radiation Protection. |
| |
| STATUS: new |
| |
| Reported By: Federal Express |
| City and state: Seattle, WA |
| License number: Not Applicable |
| Type of license: General license for Commercial Carrier |
| |
| Date of event: January 14, 2000 |
| Location of Event: Seattle-Tacoma International Airport |
| |
| ABSTRACT: During off-loading a plane early in the morning of January 14, |
| 2000, a two pound package containing 52 microcuries of I-125 labeled human |
| insulin fell off the ramp loader and came to rest un-noticed under the |
| extended ramp. The ramp was lowered after the unloading of the plane, |
| crushing the package. The crushed package was discovered later that day and |
| Federal Express procedures were followed. The package was noted to fall |
| apart as it was lowered into the barrel overpack. The state Division of |
| Radiation Protection was notified promptly via 206-NUCLEAR (the state's |
| radiation emergency line). Staff from the Division responded and determined |
| that neither the individual who had overpacked the package nor the ramp |
| loader were contaminated. The barrel overpack was opened long enough to |
| confirm the presence of removable contamination (approximately 2000 cpm per |
| 100 sq. cm. using low energy gamma scintillation probe). Direct survey |
| reading inside of the barrel showed 30,000 to 50,000 cpm. No contamination |
| was found on the outside of the barrel or the barrel's storage location. |
| |
| The package was a Type A container labeled Yellow II with a transport index |
| of 0.1 (UN2982, radioactive material, n.o.s.) shipped from Amersham |
| Pharmacia Biotech to a Seattle research lab licensed by the state. |
| |
| What is the notification or reporting criteria involved? Damaged package. |
| |
| Activity and isotope(s) involved: 52 microcuries of I-125. |
| |
| Overexposures? No individuals were exposed or contaminated as a result of |
| this event. |

| INSUFFICIENT GUIDANCE FOR ENSURING THAT A SAFETY RELATED SYSTEM WAS |
| OPERATING DURING A LOCA |
| |
| During the evaluation of a separate Condition Report concerning a Technical |
| Specification 3.0.3 entry involving the Beaver Valley Power Station (BVPS) |
| Unit 1 Supplemental Leak Collection & Release System (SLCRS), it was |
| discovered that the operators did not have sufficient guidance for ensuring |
| that this safety related system was operating following an accident. |
| |
| BVPS Units 1 and 2 Technical Specifications 3/4.7.8 Bases states "System |
| operation was assumed in that portion of the design basis accident LOCA |
| analysis which addressed ESF leakage following the LOCA Based on the |
| results of the analyses, the SLCRS must be OPERABLE to ensure that ESF |
| leakage following the postulated DBA LOCA will not exceed 10CFR 100 |
| limits." ESF leakage is a concern during a LOCA following a Safety |
| Injection Transfer to Recirculation. |
| |
| The BVPS Unit 1 and 2 operators did not have sufficient guidance to ensure |
| that a SLCRS fan is operating during a LOCA after Transfer to Recirculation |
| occurs. Thus, the SLCRS may not operate as assumed and credited in LOCA |
| safety analyses. SLCRS also provides cooling air flow to the emergency core |
| cooling pumps motors. The need for SLCRS for maintaining the qualification |
| of emergency core cooling pumps motors is proportional to the ambient |
| outdoor air temperatures. Current guidance does not ensure SLCRS would be |
| available in all conditions where SLCRS flow is required to maintain the |
| qualification of the emergency core cooling pump motors. |
| |
| This condition is an unanalyzed condition and is reportable pursuant to |
| 10CFR50.72(b)(1)(ii). |
| |
| Verbal guidance has been provided to the BVPS Unit 1 and 2 operating crews |
| to ensure a SLCRS fan is running in the event of a reactor trip or safety |
| injection. This guidance is currently being formalized. |
| |
| The NRC Resident Inspector was notified. |

| ULTIMATE HEAT SINK (UHS) BELOW MINIMUM DESIGN TEMPERATURE LIMIT OF 33 |
| DEGREES F (CONCERN IS SERVICE WATER TEMPERATURE). |
| |
| Below is the Basis for Initial Reasonable Expectation of Continued |
| Operability performed by Engineering: |
| |
| CCI is Closed Cooling for Safety Injection, CCE is Closed Cooling for |
| Charging, SW is Service Water, and Hx is Heat Exchanger |
| |
| "The concerns with low UHS temperature are pipe stress calculations and |
| possible freezing of stagnant loops such as CCI and CCE. Other portions of |
| the SW system are not vulnerable to small changes in UHS temp due to |
| constant flows and large heat sinks. Additionally, the 33 degree F limit is |
| the design basis of the plant per the FSAR and therefore is reportable if |
| exceeded. |
| |
| "CCL and CCE freezing: |
| |
| "A review of the thermodynamic characteristics of the CCI and CCE heat |
| exchangers, assuming UHS of 31 degrees F, shows that the temperature |
| gradient of the process fluid, due to the high conductivity of the copper |
| nickel pipe and room temperatures, results in CCI and CCE bulk fluid |
| temperatures remaining above freezing for an extended period of time, |
| although the bulk temperature of the shell side of the CCI heat exchangers |
| is only 32.5 degrees F. To assure operability of the SI pumps, the CCI |
| system should be started at a SWP temperature of 33 degrees F decreasing to |
| move the water through the system. The historical UHS temperature dips |
| below 33 degrees F have been for a short duration of hours followed by |
| longer warming periods. Design calculations show that CCI/SIH operate |
| properly with the entire bulk temperature at 32 degrees F. This is |
| conservative as the majority of the CCI system will remain at ambient room |
| temperature in the standby mode. Once operating, there is additional heat |
| input from the SIH pump. Therefore, there is no limit to UHS temperature |
| which would render CCI/SIH inoperable even over several hours. |
| |
| "A similar argument applies for the CCE/CHS system. The temperature |
| gradient and bulk temperature characteristics are identical. Additionally, |
| the CCE system utilizes a temperature control valve to maintain proper |
| temperatures. The failed position of this valve (LOP) is to maximum flow |
| through the SW Hx and has a position limiter designed for proper Charging |
| lube oil temperature with a 33 degrees F UHS. The supporting calculation |
| demonstrates that a 41.9 degrees F CCE inlet temperature at the lube oil |
| cooler results in a 55 degrees F lube oil temperature (minimum required |
| temperature for charging pump operability). If a service water temperature |
| of 30 degrees F is used in the LMTD equation for the CCE HX, and the delta-T |
| on both the SW & CCE sides are assumed to remain unchanged, the calculated |
| CCE inlet temperature at the lube oil cooler is 42.2 degrees F, which is > |
| 41.9 degrees F needed for the 55 degrees F lube oil temperature. |
| |
| "To prevent potential freezing of the shell side fluid in the CCI heal |
| exchangers and assure the Operability of the Safety Injection pumps, the CCL |
| pumps should be started at a SWP temperature of 33 degrees F decreasing. |
| |
| "Piping Stress: |
| |
| "The Service Water System piping, supports and equipment have been analyzed |
| to meet Code stress limits at a minimum temperature of 33 degrees F as |
| described in OD MP3-213-96. Lower temperatures will have no affect on the |
| qualification status of the piping analysis since thermal expansion induced |
| pipe stress is secondary, and is not evaluated under GL 91-18 Operability |
| rules. |
| |
| "Increases in loads for pipe supports, equipment nozzles and equipment |
| anchorage for temperatures below 33 degrees F are judged to be negligible |
| and also have no affect on the operability of these components. ERC |
| MP3-DE-96-059 revision 1 transmitted Technical Report TR-89014-1, revision |
| 2, which evaluated low temperature piping at Millstone Unit 3. This report |
| concludes that systems where the maximum operating temperature does not |
| exceed 200 degrees F, and the temperature range does not exceed 200 degrees |
| F, satisfy ASME Code requirements for thermal expansion loads. The Service |
| Water maximum temperature range is well below 200 degrees F. |
| |
| "Therefore, Service Water temperatures below 33 degrees F (to the freezing |
| point of sea water 27.5 degrees F) will have no effect on the operability of |
| Service Water piping, supports, equipment nozzles, and equipment anchorage, |
| from a stress standpoint. No compensatory action are required. |
| |
| "An OD has been prepared to support continued operation of MP3 with a |
| Service Water temperature of 31 degrees F. This OD is stored on the MP3 |
| server at K:\DeptData\MacDeb\UHSOD. Scoping calculations to support this OD |
| have been completed and reviewed. This OD must be reviewed and PORC approved |
| as required by the SM, if SWP temperatures lower than 33 degrees F are |
| recorded." |
| |
| When the tide goes out the water temperature of the Ultimate Heat Sink |
| temperature decreases and when the tide comes back in the temperature of the |
| Ultimate Heat Sink increases. At the present time the tide is going out and |
| the water temperature is 32.7 degrees F. In a couple of hours the tide will |
| start coming back in and the water temperature of the Ultimate Heat sink |
| should increase to above 33 degrees F (37 to 38 degrees F). |
| |
| The licensee notified State and Local Counties of this event. |

| ESF ACTUATION OCCURRED WHEN REACTOR CORE ISOLATION COOLING (RCIC) INBOARD |
| STEAM SUPPLY VALVE CLOSED DURING TESTING. |
| |
| During the performance of routine surveillance testing of RCIC |
| (STP-207-4538, "RCIC Isolation -RCIC Steam Supply Pressure Low Channel |
| Functional Test"), an isolation of the inboard steam supply valve |
| (E51-MOVF064) and the RCIC trip throttle valve (E51-C002) occurred. |
| |
| The Instrument and Controls Technician performing the test apparently |

| performance of subsequent steps, the isolation occurred because the |
| isolation signal input from E31-N685A was not disabled. |
| |
| The isolation signal was reset, RCIC was restored to standby in accordance |

| NO NUCLEAR CRITICALITY SAFETY APPROVAL IN PLACE. THEY HAD A UF6 CYLINDER |
| STORAGE AREA IN THE X-344A THAT HAD PREVIOUSLY BEEN MARKED AS A DOE |
| MATERIALS STORAGE AREA (DMSA). IN REVIEW OF THE DMSA, THEY DISCOVERED THAT |
| IT WAS NOT LISTED IN THE USEC/DOE LEASE AGREEMENT AS A DMSA. SINCE NO DMSA |
| WAS IDENTIFIED, USEC HAS THE RESPONSIBILITY FOR THE AREA INCLUDING |
| RESPONSIBILITY FOR NUCLEAR CRITICALITY SAFETY COVERAGE. THE AREA CONTAINED |
| MULTIPLE SMALL UF6 CYLINDERS GROUPED TOGETHER WHICH CONTAINED GREATER THAN |

| IS CONSIDERED TO BE A FISSILE MATERIAL OPERATION WITH NO NCSA IN PLACE TO |
| ANALYZE THE CONDITIONS REQUIRED TO MAINTAIN NCS SAFETY. |
| |
| THIS AREA WAS THOUGHT TO BE REGULATED BY DOE, BUT IT WAS LATER DETERMINED TO |
| BE USEC'S RESPONSIBILITY AND USEC SHOULD HAVE HAD THE NCS INPLACE. |
