NC State celebrates 70 years of nuclear engineering education

The Department of Nuclear Engineering at North Carolina State University has spent the 2020–2021 academic year celebrating the 70th anniversary of its becoming the first U.S. university to establish a nuclear engineering curriculum. It started in 1950, when Clifford Beck, then of Oak Ridge, Tenn., obtained support from NC State’s dean of engineering, Harold Lampe, to build the nation’s first university nuclear reactor and, in conjunction, establish an educational curriculum dedicated to nuclear engineering.
The department, host to the 2021 ANS Virtual Student Conference, scheduled for April 8–10, now features 23 tenure/tenure-track faculty and three research faculty members. “What a journey for the first nuclear engineering curriculum in the nation,” said Kostadin Ivanov, professor and department head.

A new diffuser/permeator design has been proposed for a new Savannah River Site tritium project. The use of a single heaterwell in the center of the shell had raised concerns that the Pd/Ag coils may be shielding radiative heat transfer to the walls thus reducing Pd/Ag tube temperatures near the shell below the recommended minimum operating temperature.The diffuser was fitted with thermocouples to measure shell temperatures during testing. Tests were run with the shell evacuated, helium Feed flows of 0, 1000, and 2000 sccm; Bleed pressures ranging from 0 to 203 kPa, and heater temperatures of 650, 675, and 700°C. Hydrogen permeation tests were run with two hydrogen/helium mixtures and Feed rates to simulate 1st and 2nd stage diffuser operations.Approximately 20 hours were required to bring the diffuser from ambient temperature to steady-state conditions. For tests with a heater temperature of 675°C and no hydrogen flow, helium flow rate and pressure had little impact on the measured shell temperatures, the thermowell temperature, roughly 415°C, and altered heater output by only 11 watts. Conversely, controlling the thermowell temperature to 415°C during hydrogen permeation tests increased heater power output, lowered heater temperature, and increased shell temperatures. The tests showed the diffuser can perform its intended function with reasonable assurance that the Pd/Ag tubes were within the recommended temperature range.
