The U.S. should carefully and prudently maintain its nuclear weapons stockpile

Defense News reports that “Nuclear gravity bomb and warhead upgrades face new delays” because of new components used in so-called Life Extension Programs (LEPs) to prolong the service lives of existing nuclear weapons. These programs also give existing nuclear weapons new military capabilities. For example, see How US nuclear force modernization is undermining strategic stability: The burst-height compensating super-fuze

The point of this blog is to raise the question of whether these Life Extension Programs really enhance U.S. national security while maintaining the safety and reliability of the nuclear weapons stockpile. In fact, perhaps the crux issue is prudent and conservative maintenance of the stockpile versus increasingly aggressive LEPs.

THE U.S. RAISES RED FLAGS ON RUSSIA’S PLUTONIUM EXPERIMENTS — WHILE RAMPING UP ITS OWN

NNSS Subcritical Experiment Preparation — Workers at the Nevada National Security Site prepare for an experiment to assess how plutonium responds to chemical high explosives.

Experiments at Russian and US underground sites are used by both nations to help ensure their nuclear arsenals remain viable but are conducted under a blanket of secrecy. And so they’ve given rise to suspicions, and accusations, that they violate a 1996 global treaty designed to stymie nuclear weapons innovations by barring any nuclear explosions.

Faulty Radioactive Liquid Waste Valves Raise Crucial Plutonium Pit Production and Safety Board Issues

There should be no expanded pit production until nuclear safety is fully assured by an independent, unrestricted Safety Board, and our congressional delegation should be the first to demand that.

LANL Continues to Have Serious Nuclear Safety Management Issues

A new report illustrates why planned expanded plutonium pit production for new nuclear weapons at the Los Alamos Lab has a high probability of failure.

NNSA’s pet ‘Interoperable Warhead’ is DEAD

U.S. W78 warheads inside MK12A re-entry vehicles on a LGM-30 Minuteman III bus next to the shroud.

The study in question came about because Marylia Kelley, of Tri-Valley CARES, and NukeWatch’s Director, Jay Coghlan, suggested to congressional staff that it be done. But they wanted to ask independent scientists (the JASONs) to do it – instead just NNSA did it. And NNSA dodged the central congressional requirement to compare the benefits and costs of the Interoperable Warhead vs a “conventional” life extension program for the Air Force’s W78 ICBM warhead. NNSA simply said a conventional life extension program would not meet military requirements and therefore summarily dismissed it (no further explanation). Marylia and Jay had the opportunity to discuss this with the relevant congressional staffer who said this ain’t over.
