During the outage, significant work was performed to resolve issues relating to "corner room" steel structural adequacy and motor-operated valve "hot short" cable concerns. Additional work activities addressed other emergent design issues, including High Pressure Coolant Injection (HPCI) Pump inlet nozzle structural modifications, and the addition of seismic bracing to a gallery platform and to reactor building ventilation. Ascension to full rated power is pending completion of control rod scram time testing. Unit 2 is operating at rated power. Regional Action: Augmented inspection coverage was provided for plant startup. Contact: B. L.

MR Number: 4-96-0095 Comanche Peak 1 Date: 09/05/96 Glen Rose,Texas Call to RI from Shift Manager Dockets: 50-445 PWR/W-4-LP Subject: DIVER'S HOSE BECOMES ENTANGLED IN RUNNING SERVICE WATER PUMP Discussion: At 12:38 p.m. on September 4, with both units operating at 100 percent power, a contract dive team was conducting an inspection of the station service water intake structure for silt, debris, and freshwater clams. The inspection was being conducted in a common bay which supplies all four service water pumps (two per unit). The diver was using hard helmet equipment which required an individual to tend the lines. The line tender felt two tugs on the lines and plied out extra line, allowing the lines to become slack. The lines were subsequently drawn into the suction of the Unit 1, Train A, service water pump. The lines became entangled in the pump and started to pull the diver toward the pump. The diver was able to take hold of a permanent structure while he disconnected himself from the lines. The diver then made an emergency ascent to the surface. Licensed operators noted a reduction in flow and secured the pump. The pump was declared inoperable which, in turn, affected the operability of the Train A emergency diesel generator and associated Train A ESF equipment. The lines that became entangled in the pump impeller consisted of a 3/8 inch air line, a 1/4 inch dive line, a 1/2 inch safety line, and a 1/4 inch shielded communications line, which were lashed together. The lines were attached to the hard hat by a brass fitting and were secured to the diver's belt by a stainless steel D-ring. After securing the pump, divers removed some of the line from the pump, which included the brass fitting and the D-ring. The licensee does not believe that these items entered the pump. Once the lines are removed from the pump and visual inspections of the impeller are completed, the licensee intends to perform a surveillance test on the pump to include a vibration analysis. Pending satisfactory performance of the test, the licensee intends to declare the pump operable. Regional Action: The resident inspectors will monitor the licensee's corrective actions related to this event. A followup inspection will be conducted as appropriate to assess the potential safety implications of this event, including the similarity to a previous event where a fire hose was inadvertently drawn into a service water pump.
