This is a life and death important topic for future generations, as well as our own. And, the US NRC has given less than 2 months to comment on a 129 page document. Only 2 people have commented. Many have not heard. Please comment, spread the word, and ask for an extension to this deadline. We put some related information and the link for comments below. It’s easy and can be anonymous. You can, for instance, read a piece of the document and comment on that, while asking for an extension.

Introduction Loads on Fuel Rods, Billone 2013

HBU is High Burnup Nuclear Fuel.
Dry Storage and Transportation of High Burnup Spent Nuclear Fuel

This Notice document was issued by the Nuclear Regulatory Commission (NRC)
Action Draft NUREG; request for comment.
The U.S. Nuclear Regulatory Commission (NRC) is issuing for public comment a draft NUREG, NUREG-2224, “Dry Storage and Transportation of High Burnup Spent Nuclear Fuel.” The draft NUREG provides technical background information applicable to high burnup spent nuclear fuel (HBU SNF), provides an engineering assessment of recent NRC-sponsored mechanical testing of HBU SNF, and proposes example approaches for licensing and certification of HBU SNF in transportation and dry storage.
Submit comments on the draft NUREG-2224 by September 24, 2018. Comments received after this date will be considered if it is practical to do so, but the NRC is able to ensure consideration only for comments received on or before this date…

Clearly, Areva’s M5 cladding does not perform the same as Zircaloy or ZIRLO. It may be similar, but it’s not the same. M5 – green dots – fails in fewer cycles and at lower strain amplitude, according to this small sampling. So does M5 red triangles (with MOX). This is from a 2016 presentation. Like Surry which just got an exemption, North Anna has PWRs (Pressurized Nuclear Reactors), though the Surry ones are much older. HB Robinson has a PWR, but Limerick has BWRs.
