Abstract: In combination with a nuclear power generating facility including a composite fuel pool including a reactor cavity and a spent fuel pool fluidly connectable to the reactor cavity, the composite fuel pool at least partially containing a primary fluid, a nuclear reactor vessel positioned in the reactor cavity, a residual heat removal system installed in the facility and fluidly connectable to the reactor vessel, and a spent fuel pool cooling system installed in the facility and fluidly connectable to the spent fuel pool, a temporary cooling system is provided, comprising a primary heat exchange system including a primary heat exchanger for transferring heat from a primary fluid to a secondary cooling fluid. The primary heat exchanger is temporarily locatable in the facility, and is temporarily fluidly connected to the composite fuel pool.

Abstract: A steam generator chemical solvent mixing system and method is provided. The chemical solvent mixing system includes a pump, having a discharge port fluidly connected to a discharge line and a suction port fluidly connected to a suction line. An upper level injector, including an injector nozzle extends through one upper access opening in the outer casing of a steam generator and extends into the annulus of the generator between the tube bundle shroud and the outer casing, the upper level injector being fluidly connected to the discharge port of the pump. A lower access eductor is provided, including an eductor nozzle extending through one lower access opening of the outer casing and adapted to discharge solvent through one passageway in the tube bundle shroud and into the tube bundle of the generator, the lower access eductor being fluidly connected to the discharge port of the pump.

Abstract: An earthmoving scraper including an overhung tractor and a trailing scraper bowl in which the latter units are respectively provided with a front axle and a rear axle having a pair of driven wheels. The rear axle of the scraper is rigid with the scraper bowl while the front axle is supported by a suspension including a leading arm the front end of which is fixed with the front axle and the rear end of which is supported by the tractor frame for pivotal movement about a transverse horizontal axis located below a horizontal plane passing through the rotational axis of the front wheels. Spring means are provided between the front axle and the tractor frame for cushioning movement of the front axle about the aforementioned transverse horizontal axis.
