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 a water source;
b) a water soluble boron powder source;
c) a heater to heat the water;
d) a pump operable to provide a motive force to move water to a desired location;
e) a metering system configured to provide a metered flow of the boron powder source and water heated by the heater;
f) a mixer configured to provide metered mixing of the heated water and the water soluble boron source to provide a metered concentration of water/boric acid slurry;
g) a dilution tank;
h) a hot stream conduit connected between the mixer and the dilution tank, configured to convey the heated water/boric acid slurry to the dilution tank;
i) a dilution stream conduit connecting an inlet port on the dilution tank to a cool dilution stream relative to the heated water/boric acid slurry;
j) a diluted boric acid output connected to an exit port on the dilution tank for conveying a mixture of the dilution stream and the heated water/boric acid slurry to a nuclear reactor system;
k) a transport arrangement configured to transport the mobile boration system to the nuclear reactor system, wherein the transport arrangement eliminates the need for onsite storage of conventionally large volumes of borated/boric acid water solutions; and
l) an insulated chamber housing the mixer and a length of the hot stream conduit with the dilution tank outside of the insulated chamber.

Abstract
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.
