Production test IP-805, irradiation of neptunium target elements

PDF Version Also Available for Download.

Description

A sustained demand for large quantities of plutonium 238, a heat generating isotope, formed by irradiation of neptunium 237, is anticipated over the next ten to fifteen years. Plutonium 238 is thus a natural candidate as an alternate product for production reactors. Detailed studies have been completed outlining the advantages and incentives of producing plutonium 238 at Hanford. A primary conclusion of these studies is that more efficient production is possible in Hanford`s relatively low neutron fluxes. Under irradiation neptunium 237 captures a neutron, then decays to plutonium 238 by beta emission. The intermediate product, neptunium 238 has a high ... continued below

Description

A sustained demand for large quantities of plutonium 238, a heat generating isotope, formed by irradiation of neptunium 237, is anticipated over the next ten to fifteen years. Plutonium 238 is thus a natural candidate as an alternate product for production reactors. Detailed studies have been completed outlining the advantages and incentives of producing plutonium 238 at Hanford. A primary conclusion of these studies is that more efficient production is possible in Hanford`s relatively low neutron fluxes. Under irradiation neptunium 237 captures a neutron, then decays to plutonium 238 by beta emission. The intermediate product, neptunium 238 has a high capture cross section; therefore in a low flux field a greater proportion decays to the desired product. More efficient utilization is an important advantage since the amount of plutonium 238 that can be produced is limited by the availability of target neptunium. The referenced studies and conclusions drawn therefrom are based entirely on analytical calculations. Experimental data are needed to confirm the calculations and demonstrate Hanford`s capability. The objective of this production test is to obtain experimental data on plutonium 238 production in Hanford reactors.
