The Materials Test Station (MTS) is a project by the Advanced Fuel Cycle Initiative to build a facility that allows for irradiating nuclear fuel and material samples to acquire the necessary knowledge to close the nuclear fuel cycle and thereby reduce the amount and the toxicity of the nuclear waste. This facility is proposed to be located in Area A of the Los Alamos Neutron Science Center at the Los Alamos National Laboratory. The MTS is proposed to be a spallation target facility operated up to 2 MW (2.5 mA at 800 MeV). To safely operate a facility of this size, a large amount of shielding needs to be put into place. In this paper we will discuss the shielding design proposed for the MTS.
