NNSA awards BWXT $1.5B defense fuels contract
The Department of Energy’s National Nuclear Security Administration has awarded BWX Technologies a contract valued at $1.5 billion to build a Domestic Uranium Enrichment Centrifuge Experiment (DUECE) pilot plant in Tennessee in support of the administration’s efforts to build out a domestic supply of unobligated enriched uranium for defense-related nuclear fuel.

A satellite carrying radioactive material in a near-Earth orbit has a finite probability of reentering before the radioactivity has decayed to a harmless level. If the reentry is unplanned, it is normally impossible to predict the impact point to a useful degree of accuracy. This paper deals with such cases. The probability distribution function for latitude of impact is derived for a general case. This function is then combined with an injury probability model and a population distribution model to compute probabilities of injury. The results are correlated as the dependence of probability of injury on latitude and orbital inclination angle. It is shown that probability of injury peaks for an orbital inclination of 30 to 60°.
