Tonk, It looks like brat lives in Las Vegas.
Rather than worrying about safe shipping, I'd bet he's more worried that the shipment will safely arrive and arrive and arrive...
I'm willing to believe Yucca Mtn is safe as soon as the NRC gives it the final OK. Some 20 years of studies and they (NRC) are still not sure.
They have the only legal authority to open it.
I'll believe shipping across country is safe as soon as our borders are sealed.
