Favorite Reg: ‘Probabilistic Risk Assessment in Risk-Informed Decisions’

As regulatory guides go, “An Approach for Using Probabilistic Risk Assessment in Risk-Informed Decisions on Plant Specific Changes to the Licensing Basis” certainly must be a classic.

It’s the avowed favorite of Nuclear Regulatory Commissioner George Apostolakis.

So he said at the annual all-employees meeting, which gave rise to a contest asking employees to nominate their favorites — with the agency dangling a $50 prize, a gift to an employee’s favorite charity in the Combined Federal Campaign.

Adam Glazer, an IT specialist, won the contest “with his tongue-in-cheek tribute to Regulatory Guide 10.8 – otherwise known as the “Guide for the Preparation of Applications for Medical Use Programs.” His tribute claimed that particular guide had been involved in historic events ranging from saving the troops at Valley Forge in 1775 to helping mediate peace during the Russo-Japanese War of 1904-1905,” the NRC reports at its blog.

“In a more serious vein, Julio Lara, of Region III, declared Regulatory Guide 1.26 “Quality Group Classifications and Standards for Water-, Steam-, and Radioactive Waste-Containing Components of Nuclear Power Plants” as his favorite. That guide had tripped him up during his Inspector Qualification Oral Board in 1989, and he had to study it and twice demonstrate his knowledge of it before being certified as an inspector.”

“Christine Lipa, also of Region III, also had a personal reason for her favorite regulatory guide. She cited Regulatory Guide 1.97, “Criteria for Accident Monitoring Instrumentation for Nuclear Power Plants.” This document provided guidance to the nuclear power industry as it implemented new requirements after Three Mile Island accident. “When I was a new inspector in Region III in 1990, this was the first set of inspections I was involved in,” she wrote.”

“In his submission, Stuart Richards, of the Office of Regulatory Research, declaredRegulatory Guide 1.1 “Net Positive Suction Head for Emergency Core Cooling and Containment Heat Removal System Pumps” as his favorite. He said it was the first safety guide (dated November 1970), it was only one page long and it has never been revised “so it must be good.”
