Temporary Cooling System And Method For Removing Decay Heat From A Nuclear Reactor

US Patent:
5268942, Dec 7, 1993
Filed:
Sep 10, 1992
Appl. No.:
7/943044
Inventors:
Peter M. Newton - Richland WA
John B. Mason - Pasco WA
Steven K. Hamilton - Columbia SC
Assignee:
Pacific Nuclear Systems, Inc. - Richland WA
International Classification:
G21C 1900
US Classification:
376272
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. A primary pump, also temporarily locatable in the facility, circulates primary fluid through the primary heat exchanger, which cools the primary fluid to a desired point at a faster rate than the spent fuel pool cooling system, allowing fuel to be immediately removed from the reactor rather than waiting for the residual heat removal system to cool the primary fluid to a point at which the spent fuel pool cooling system is able to provide adequate cooling capacity.

Steam Generator Chemical Solvent Mixing System And Method

US Patent:
5257296, Oct 26, 1993
Filed:
Oct 25, 1991
Appl. No.:
7/783621
Inventors:
Albert C. Buford - Cabot AR
Donal W. Moore - Russellville AR
Sterling J. Weems - Chevy Chase MD
John B. Mason - Pasco WA
International Classification:
G21C 1942
US Classification:
376310
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. A gas injection line is provided, fluidly connected at one end to a gas source and at the other end to the lower access eductor. A return line fluidly connects at one end to a second lower access opening and at the other end to the suction port of the pump.

In-Container Mineralization

US Patent:
7476194, Jan 13, 2009
Filed:
Oct 22, 2004
Appl. No.:
10/972068
Inventors:
John Bradley Mason - Pasco WA, US
Thomas W. Oliver - Marietta GA, US
Assignee:
Studsvik, Inc. - Atlanta GA
International Classification:
B09B 3/00
US Classification:
588252, 588254
Abstract:
A method of waste stabilization by mineralization of waste material in situ in a treatment container suitable or treatment, transit, storage and disposal. The waste material may be mixed with mineralizing additives and, optionally, reducing additives, in the treatment container or in a separate mixing vessel. The mixture is then subjected to heat in the treatment container to heat-activate mineralization of the mixture and form a stable, mineralized, monolithic solid. This stabilized mass may then be transported in the same treatment container for storage and disposal.
