Molten Sodium Interactions with Basalt Concrete and Siliceous Firebrick
The interactions of molten sodium with fast reactor construction materials are being investigated for safety analysis purposes. Basalt concrete has been used in the floor of the containment building under the reactor vessel in certain reactor designs. In these designs, the basalt concrete is protected by a steel liner and several courses of firebricks. Molten sodium was poured into large basalt concrete crucibles. For one test, the cavity of the concrete crucible was unprotected. In another test, the cavity was covered with two layers of firebricks and a steel insert. The third test also used firebricks and a steel insert, however, the cavity sidewalls were excluded from the test in an effort to present the cavity bottom with a one-dimensional sodium attack. In the latter two tests, the steel insert was intentionally flawed so that the sodium might come in contact with the firebricks and the concrete. In all three of these tests, vigorous exothermic reactions were observed between the sodium and the concrete and between the sodium and the firebricks. The reactions continued until all of the sodium had been consumed. The three basalt concrete crucibles cracked severely.
