Officials at the U.S. Nuclear Regulatory Commission have frequently decided that original regulations were too strict, arguing that safety margins could be eased without peril.

Examples abound.
When valves leaked, more leakage was allowed — up to 20 times the original limit.
When rampant cracking caused radioactive leaks from steam generator tubing, an easier test of the tubes was devised, so plants could meet standards.
