SAMG actions prescribed for such a scenario include water injection into steam generator, calandria vessel or calandria vault at different stages of accident.
Numerous fretting damages exist at various parts of nuclear power systems [7], such as reactor fuel assembly, control rod assembly [8], reactor component, steam generator, pressure vessel [9], main pump, and coolant pump.
The Japan Steel Works Ltd. (JSW) has many manufacturing experiences of large integrated forgings made from high strength MnMoNi steel with tensile strength level of 620 MPa for steam generator (SG) pressure vessel, and has performed confirmation tests of its material properties.
However, because of three episodes of broken peripheral venous catheter tips left in the vessels, generator displacement requiring surgical intervention, and emotional fragility, the surgical intervention was postponed due to the high possibility of postoperative wound infection and further osteomyelitis.
However, the fire destroyed the vessel's generators, apparently because intense heat forced the crew to abandon the engine room.
Cleaning the vessel's generators was the work scheduled for the 29th, and since the cleaning work was to be done with carbon tetrachloride, known to have toxic properties, a Saturday was chosen for the job to minimize the number of persons aboard the vessel.
Rhyne raised concerns about noise, diesel smoke from the generators, where the vessels plan to fuel and how they will affect the harbor bottom.
The main components of the primary loop pressure boundary system consist of the reactor pressure vessel, the steam generator pressure vessel and the hot gas duct vessel.
A loose part monitoring system is used to identify unexpected loose parts in a nuclear reactor vessel or steam generator.
