Seaborg MSR: liquid moderator

Post by camiel » Jan 22, 2019 1:53 pm

Reading through the IAEA SMR Book (see below, p. 201-204) I came across the Seaborg MSR design. Seaborg is a Danish company which has presented an innovative MSR design in the sense that their reactor design makes use of a liquid moderator (proprietary and patent pending), instead of graphite, making the reactor also more compact. I haven't seen this before in other SMR designs. Is using a liquid moderator a smart innovation ?

There is also recent patent application for this Seaborg MSR design, with a description of the moderator fluid (hydroxide), published by the World Intellectual Property Organization in December 2018:

Would this have any design history related to AHR types?

A liquid moderator would not suffer from lower life like the graphite. Hydrogen atoms are the lightest and a less volatile hydrogen compound or a solution of compounds is the right choice. Perhaps we should develop a number of reactor oils for use as reactor moderators.
