LOS ALAMOS, N.M. (AP) - The agency that oversees the nation's nuclear weapons stockpile has yet to release a report on the risks and capabilities of Los Alamos National Laboratory and other U.S. Energy Department sites when it comes to producing plutonium cores for the weapons.
The report by the National Nuclear Security Administration was due over the summer but nothing has been made public other than a redacted summary sheet obtained by a watchdog group in the wake of recent congressional briefings.
The summary suggests it would be most costly to continue producing plutonium pits at Los Alamos.
Members of New Mexico's congressional delegation suggest the evaluation process was flawed. Others are voicing concerns about Los Alamos' safety record.
No new pits have been made since 2011. The Energy Department wants to ramp up production to 80 pits annually by 2030.
