Chemical Debris ECCS Strainer Hamaoka NPP Head Loss Evaluation NPSH
ECCS strainer for Hamaoka NPP employs cassette type. At the time of severe accident, it is necessary to take into consideration the chemical debris which has not been considered in BWR so far, in order to carry out pH control in the reactor containment vessel. In this paper, we report the results of closed vertical pipe loop test on the evaluation of the ECCS strainer head loss when considering the chemical debris in addition to the debris such as coating generated at the time of severe accident....

Condition Based Maintenance horizontal type pumps vibration diagnostic technology
In Hamaoka nuclear power station, Condition Based Maintenance (CBM), which uses vibration diagnosis technology, has been introduced for some rotational devices such as horizontal type pumps or fans. Until now, a lot of instances, which include predicting a failure of bearing by detecting an upwarc tendency of vibration, and reducing an oscillation by adding adequate oil following a detection of insufficient bearing lubricant, show that CBM has an adequate predictive function as preventive maintenance metho...

earthquake middle standard bearing box special maintenance plan steam turbine thrust bearing
Hamaoka Nuclear Power Station Reactor No. 5 was automatically shut down when an earthquake occurred in Suruga Bay on August 11, 2009. A special maintenance plan for inspections to verify the soundness of equipment and facilities in Hamaoka Nucle ar Power Station was formulated following the earthquake. The main steam turbine in Hamaoka Nuclear Power Station Reactor No. 5 was inspected based on the plan. The middle standard bearing box, which had the thrust bearing of the turbine was fou nd to lift slightly...

condenser pipe break corrosion field experience plant survey sea water infiltration
In the process of achieving cold shutdown following the shutdown of Hamaoka Nuclear Power Station Unit 5 on May 14, 2011, large quantities of seawater flowed into the reactor and other facilities due to main condenser tubes which had broken. The investigations focusing on corrosion of materials had been conducted through various methods, observation of equipments, material tests, cleaning tests, and inspection of RPV and its components. Based on these investigations, we had evaluated the impact on the...
