U.S. Nuclear Regulatory Commission
Question 115: The words, "e.g., containment or ventilation," have been added to 10 CFR 20.1701. Does this mean that increased emphasis is being placed on glove bags to do valve replacements, repacks, etc. at nuclear power plants?
Answer: No. These words were added simply to provide examples of "process or other engineering controls."
(Reference: 10 CFR 20.1701)
