However, salt has an extremely high melting temperature — 550°C — and it doesn’t take long for the temperature of these elements in the salt to fall beneath the melting point.Another benefit of the molten salt nuclear reactor design is that it has the potential to eliminate dangerous nuclear waste.The products of the reaction are safely contained within the salt, with no need to store them elsewhere.What’s more, many of these products are valuable, and can be removed from the salt and sold.We can recycle the salt indefinitely.”A typical nuclear power plant is built with a little over one square mile to operate to reduce radiation risk, with the core itself being 30 ft x 30 ft. Memmott’s molten salt nuclear reactor is 4 ft x 7ft, and because there is no risk of a meltdown there is no need for a similar large zone surrounding it."
