Proving DRACO will deliver
The United States is now closer than it has been in over five decades to launching the first nuclear thermal rocket into space, thanks to DRACO—the Demonstration Rocket for Agile Cislunar Orbit.

Damage caused by neutrons in the first wall of fusion reactor is studied in detail for two different structural materials (Type 316 stainless steel and Nimonic PE-16) in the Princeton fusion power plant design. The first-wall neutron spectrum is calculated by the ANISN code, and a dosimetric analysis is performed for both materials. Moreover, a complete study of damage (swelling and creep) during reactor life is done for Type 316 stainless steel. On the basis of a 1% creep strain, the lifetime of a Type 316 stainless steel first wall is calculated to be ∼2 yr, compared with the ∼22-yr lifetime obtained for Nimonic in the Princeton design. In this way, the economic advantage of a superalloy, compared to stainless steel, has been confirmed.
