WebJun 5, 2024 · The pebble bed has superior heat transfer with an operating region reduced . ∼ 10% less when switching coolants and . ∼ 50% smaller uncertainty than the prismatic. The maximum fuel temperature constrains the pebble bed while the maximum coolant temperature constrains the prismatic due to different dominant heat transfer modes. WebCoolant. FLiNaK salt was researched heavily during the late 1950s by Oak Ridge National Laboratory as potential candidate for a coolant in the molten salt reactor because of its low melting point, its high heat capacity, and its chemical stability at high temperatures. Ultimately, its sister salt, FLiBe, was chosen as the solvent salt for the molten salt …
