Used WATKINS JOHNSON WJ 999 #9202469 for sale

WATKINS JOHNSON WJ 999 reactor is a state-of-the-art, high-performance, dual-loop type graphite-moderated, natural-circulation-cooled nuclear reactor developed and manufactured by WATKINS JOHNSON. The main components are the reactor core, reactor vessel, instrumentation and control equipment, service water system, and the steam generator. The reactor core of WATKINS JOHNSON WJ999 is a stainless steel cylinder containing 65 fuel assemblies which are arranged symmetrically around a central axis. The fuel assemblies are made of low-enriched uranium rods and are cooled and moderated by graphite rods. The fuel assemblies are arranged in a hexagonal pattern to optimize pressuriser and neutron flux distribution. The neutron flux is monitored and controlled automatically by the reactor control unit. The reactor vessel is comprise of two concentric shells, an inner shell that houses the core and an outer shell that provides a pressure vessel and leak-tight containment. It is designed to meet both safety and efficiency standards while providing a high degree of radiation shielding for personnel and equipment. The pressure vessel is surrounded by a concrete safety shield and is designed to contain potential radiation or coolant leakage. The Instrumentation and Control (I&C) machine of WJ-999 is designed to monitor the process parameters and adjust the reactor parameters for efficient operation. It consists of a variety of sensors that monitor the elements of the tool and a control asset which adjusts the circuitry to regulate the reactor parameters. The service water model of WJ 999 is designed to keep the reactor cool by supplying coolant to the core during normal operating conditions. The equipment consists of pumps, storage tanks, bypass valves and gauges which help in regulating the flow of coolant throughout the reactor. The coolant is maintained at a pressure and temperature above the saturation point so that it is in a liquid state. WATKINS JOHNSON WJ-999 reactor also comes equipped with a steam generator. This is a heat exchanger that produces steam from the reactor's residual heat. The steam generator is connected to the service water system and ensures the efficient transfer of heat from the core to the steam generator. WJ999 reactor is a high-performance, reliable nuclear reactor that is designed to be safe and efficient. The advanced design and features make it one of the best available reactors on the market today.
