Irradiation of MetGlas samples in position E-1 of the reactor core is described. Data are tabulated on neutron energy and flux, and irradiation time. Data are also included on a specimen of 304 stainless steel cut from the irradiation assembly liner to be used for dosimetry. (JRD)

A survey was made of protection and suppression technologies relative to liquid sodium fires at selected sites. These technologies will find application in the Liquid Metal Fast Breeder Reactor (LMFBR) program. Based on this survey, a series of conclusions and recommendations are given. Dry type powder agents will only be of use of relatively small sodium fires. Large fires will be extinguished by inerting the chamber or collecting pans where the sodium leak occurs. Liquid sodium fire suppression methods must be incorporated into the initial design of an LMFBR. There exists a need for close coordination of liquid sodium fire technology and guidelines for fire fighting personnel. Suggestions are made for a number of technical development programs. An extensive search for new suppression agents is not recommended although carbon microspheres should be submitted for approval.
