| PACKAGE AT DALLAS FORT WORTH (DFW) AIRPORT EXCEEDS RADIATION LIMITS BASED ON |
| LABELING |
| |
| "The package exceeded the package limits based on the labeling and the |
| container. Radiation readings were about 17 mR/hr. at one meter. The limit |
| was 10 mR/hr. at one meter. A yellow Ill and Yellow II label provided |
| inconsistent radiation information. The package was held at a cargo bay by |
| US Customs. The TDH/BRC responded to a call for assistance to survey the |
| package and help determine its contents. The inspector responded on site |
| performed a survey and notified the Licensee's RSO. The Licensee planned to |
| send a representative to repackage and relabel the package prior to the |
| package being released for shipment to Houston, TX. The information provided |
| is preliminary and based on telephone conversations with involved parties." |
| |
| The package was air cargo on an international flight being shipped from |
| Schumberger in Singapore to Schlumberger in Houston, TX. |
| |
| The Texas Department of Health, Bureau of Radiation Control has notified NRC |
| R4, US Customs, DFW, and the licensee. |
| |
| The Texas Department of Health, Bureau of Radiation Control incident number |
| is I-7962 |

| UNANALYZED CONDITION |
| |
| "Inspection of the Harris Nuclear Plant (HNP) Safe Shutdown Analysis (SSA) |
| in Case of Fire identified that for postulated fires in three fire areas, |
| the design and compensatory actions assumed by the Safe Shutdown Analysis |
| would not ensure a protected train of equipment would remain available. This |
| condition constitutes noncompliance with the HNP FSAR and is reportable as |
| an unanalyzed condition as described in 10CFR50.72. |
| |
| "The inspection identified that postulated fires could cause spurious |
| actuation of components potentially resulting in loss of the Charging/Safety |
| Injection Pump (CSIP) assumed to be protected by the Safe Shutdown Analysis. |
| The fires were postulated to cause spurious closure of valves in the suction |
| and/or discharge flowpaths for the protected CSIP prior to implementation of |
| the preplanned actions designed to preserve these flowpaths. The protected |
| CSIP could be lost if it was in service at the time of the postulated fire. |
| |
| "The plant is instituting several interim compensatory measures to minimize |
| the impact of the postulated fires. These measures include aligning the |
| Charging System and de-energizing certain valves to minimize susceptibility |
| to mal-operation of components, and posting a fire watch in fire areas of |
| concern." |
| |
| The three areas of concern for the postulated fires are in the 261 RAB |
| elevation north-south hallway. The cable spreaders in this area constitute |
| the susceptible equipment. |
| |
| The NRC Resident Inspector was notified. |

EVENT TEXT

| AUTOMATIC REACTOR SCRAM AFTER EHC FAILURE |
| |
| At 2035, an EHC failure occurred that caused multiple bypass valves to open. |
| Reactor pressure dropped resulting in a Group 1 isolation (closure of |
| MSIV's) which caused a reactor scram. Lowest pressure was approximately |
| 850#. Level dropped through Lo Level (1"), resulting in Group 2/3 PCIS |
| isolation. Level continued to Lo Lo Level (-48"), resulting in ECCS |
| actuation and injection (HPCI & RCIC). ARI also initiated resulting in trip |
| of both Recirculation pumps. Plant is stabilized and preceding to cold |
| shutdown. |
| |
| The Licensee has notified the NRC Resident Inspector. |
| |
| The plant currently has MSIV's shut due to 3 Bypass valves open and are |
| maintaining pressure control with HPCI & RCIC. |

| AUTOMATIC REACTOR TRIP CAUSED BY MAIN GENERATOR TRIP |
| |
| Automatic reactor trip caused by main generator backup relay protection |
| trip. The plant currently is stable in mode 3 with Auxiliary Feedwater in |
| service for decay heat removal. All control rods fully inserted, no primary |
| relief valves lifted and no ECCS actuation occurred. The Licensee reports |
| that the electrical grid is stable and all emergency diesels are available. |
| |
| |
| The Licensee has notified the NRC Resident Inspector. |
