Mobile boration system

摘要

A mobile boration system (60) has a number of components that are mobile and include a water source (10), H2BO3 powder supply (14), a mixer to mix the solution (20) capable of providing a boric acid solution (30) with minimal air entrainment and optional heat exchanger(s) (12), and wherein the system (60) is capable of transport to a nuclear power plant facility by land, sea or air, rather than being in place in a large vulnerable footprint.

主权项

1. A mobile boration system configured to provide nuclear reactor systems with borated coolant that can mix components of the borated coolant on site, to provide borated water, the mobile boration system comprising:
a) a water source or a connection to an external water source; b) a water soluble boron powder source; c) a heater to heat the water; d) a pump operable to provide a motive source to move water to a desired location; e) a metering system configured to meter flow of the boron powder source and water heated by the heater; f) a mixer configured to allow metered mixing of the heated water and the water soluble boron source to provide a metered concentration of water/boric acid slurry; g) a further heater configured to heat the slurry, wherein mixing of the slurry by the mixer and heating of the slurry by the further heater provides a borated/boric acid water solution; h) a fluid exit for the solution; and i) a transport arrangement configured to transport the solution to a nuclear reactor system, wherein the transport arrangement eliminates the need for onsite storage of conventionally large volumes of borated/boric acid water solutions.
