Division Spotlight
Aerospace Nuclear Science & Technology
Organized to promote the advancement of knowledge in the use of nuclear science and technologies in the aerospace application. Specialized nuclear-based technologies and applications are needed to advance the state-of-the-art in aerospace design, engineering and operations to explore planetary bodies in our solar system and beyond, plus enhance the safety of air travel, especially high speed air travel. Areas of interest will include but are not limited to the creation of nuclear-based power and propulsion systems, multifunctional materials to protect humans and electronic components from atmospheric, space, and nuclear power system radiation, human factor strategies for the safety and reliable operation of nuclear power and propulsion plants by non-specialized personnel and more.

TerraPower begins U.K. regulatory approval process
Seattle-based TerraPower signaled its interest this week in building its Natrium small modular reactor in the United Kingdom, the company announced.
TerraPower sent a letter to the U.K.’s Department for Energy Security and Net Zero, formally establishing its intention to enter the U.K. generic design assessment (GDA) process. This is TerraPower’s first step in deployment of its Natrium technology—a 345-MW sodium fast reactor coupled with a molten salt energy storage unit—on the international stage.

Neutron activation cross sections between 15 and 40 MeV were measured by the activation method using a monoenergetic neutron field based on the 7Li(p,n)7Be reaction. Natural samples of carbon and cobalt, and separated isotope samples of 30Si, 47Ti, 48Ti, 52Cr and 58Ni were irradiated in the p-Li neutron fields generated by 20, 25, 30, 35, and 40 MeV protons. Neutron yields were determined from the amount of 7Be induced in the lithium target. The amount of 7Be was measured by observing the 0.478-MeV gamma rays of 7Be(T1/2 = 53.29 days) after the irradiation experiment. Cross sections of 12C(n,2n)11C, 30Si(n,np)29Al, 47Ti(n,np)46m+gSc, 48Ti(n,np)47Sc, 52Cr(n,2n)51Cr, 59Co(n,2n)58m+gCo, 59Co(n,3n)57Co, 59Co(n,4n)56Co, and 58Ni(n,2n)57Ni are reported.
