My understanding is that Silex technology can enrich uranium to weapons grade. That might be another urgent need

Washington Examiner

"The United States’s ability to deter its adversaries from attacking us and our closest allies and partners is at its lowest level since the end of the Cold War. China and Russia’s nuclear arsenals are growing unchecked, along with their ambitions, while America’s anemic response leaves it open to their coercion.
Despite the unambiguous and growing set of threats, the United States is failing to sustain its nuclear arsenal or prepare for the future. These failures will have grave consequences if not urgently addressed. President Joe Biden must make rebuilding the nation’s strategic nuclear deterrent a top priority.
A supposedly significant nuclear modernization process initiated by former President Barack Obama is currently underway. Unfortunately, that effort is not going well.
For example, the United States has not produced a new war reserve plutonium pit (a vital component necessary to create nuclear detonations) since 1989, and current efforts to restart the capability are years behind schedule. After not having built a new nuclear weapon or produced nuclear fissile material in almost three and a half decades, the U.S. must relearn how to enrich uranium for defense purposes."
