Matthews, R R

The BR 5 has a maximum power of 5 mw(t), is fueled with plutonium oxide stainless-steel clad pins, and cooled by sodium. Control is by a cickel reflector external to the central sodium tube. Shielding consists of a 20 in. thick water tank followed by a cast iron ring 16 in. thick, and the whole enclosed in a concrete cell of 43 in. average thickness. The reactor has an experimental sodium loop which can operate up to 600 deg C and is cooled independently of the main circuit. The inlet and outlet circuits to the reacior are split into circuits provided with isolating and non-return valves, a sodium to NaK heat-exchange, a mechanical pump, and cold trap. One secondary circuit is air-cooled and the other generates steam, mercury being used as the heat transfer medium in the interspace of the double wall shelland-tube type heat exchanger. (C.J.G.)
