Thanks, Stephen, for confirming what we have already been assuming,
based upon our builds. And no, I would have very much liked to see a
different answer.

Let me just ask a few follow-ups:

a) Is this by design, or ...
b) Is this a current limitation of the reactor ?
c) Could this be overcome (in theory, at least), and
d) What would it take to see this changed ?

Thanks for your time
Werner
