This paper concerns the safety aspects and design features of the Texas Cold Neutron Source (TCNS), which was designed and recently constructed by the Nuclear Engineering Teaching Laboratory (NETL) at the University of Texas at Austin. The TCNS fits into the piercing beam port of the NETL 1-MW Triga Mark II reactor. The major safety considerations for the TCNS are radiolysis of the moderating material, ozone generation in vacuum chamber, radioactivity of components, and various system failures. The use of mesitylene for the cold source moderator, a heat pipe to cool the moderator, and appropriate procedures during normal operation and system failures allows for a safe and reliable operation of the TCNS. This new facility will provide a subthermal and low-background neutron beam that will enhance the quality of basic and applied research carried out at the NETL.
