Standard Specification for Sintered Gadolinium Oxide-Uranium Dioxide Pellets for Light Water Reactors
STANDARD published on 1.1.2021
Why Redline?
A PDF redline is a quick and easy way to compare all of the changes between the current, active standard and the previous version.
With a redline you'll immediately see:
Save Time and Trouble!
With a Redline you no longer have to spend time trying to determine what has changed in the new standard! Redlines save you time and ensure you see what the changes are to the standard.
Price
When you select the "Active + Redline" option you get both documents! Best of all, the cost of an Active + Redline is only slightly more than buying the Active Standard by itself.
