I disagree.  You can eliminate all technological risk and still need a 
risk register.  The basic message is that we've done the R&D necessary 
to prove that we will be able to build something that meets the specs. 
However, the exact implementation might yet change wrt our current 
thinking.  That's what uncertainties and risk cover.

Every statement from NSF around the "construction read" indicates that 
what they mean is that you know you'll be able to meet the spec.

Best,
