The LAMPRE-I project is summarized in terms of capsule development, sodium system, LCX-III, gas system, and fuel transfer and storage. The 2-Mw Sodium Test Facility was initially placed in operation on Mar. 15, 1960. Since startup, operation has been continuous except for 12 forced shutdowns required for maintenance of auxiliary steam-system equipment and repair of refractory setting in the gas-fired sodium heater. Essentially no maintenance or adjustment hns been required on sodium components or the steam generator. The steam- generating unit is illustrated and design heat-transfer criteria and observed heattransfer data are given. The intermediate sodium heat exchanger, centrifugal sodium pumps, gas-fired sodium heater, sodium flow-control valves, and purification cold trap are discussed briefly. Research and development activities for the LAMPRE Program are reported in the core-development program, core-test facility, mobileblanket studies, fuel-alloy development, container- materials development, and fuel processing.
