What process would you prefer? The General Manager is in charge of  
day to day business operations (as stated in the By-Laws). Because  
there isn't currently a GM, I believe leads for each committee are  
coordinating with the board to make daily decisions. Brian can  
correct me if I'm wrong.

If you prefer, you can just work with Thom Tricola and he can  
coordinate with the board and felix regarding making decisions.

It is my understanding that the current set-up was what was done to  
get us making fuel quickly. We are moving as quickly as we can to a  
Phase II processor that will address larger safety and efficiency  
concerns. In the meantime, we have to do the best we can. I believe  
moving that one relay away from the reactors will be an important  
safety upgrade.

As long as they don't actually shut us down, I think it would be  
important to get their recommendations and feedback. We know there is  
a possibility that we are not meeting code with our current set-up.  
If you feel uncomfortable with that, we should address your specific  
concerns and decide whether you want to do the work. I don't think  
you should get involved if you feel uncomfortable about doing so,  
however your recommendations are invaluable feedback to us and will  
help us make decisions on how to proceed, obviously.

That is what we're looking for *while still reaching forward as much  
as is feasible with time and work constraints*. How much is one  
explosion proof box roughly if we can't move the relay?

That is an excellent idea. I'm ccing your email to the safety  
committee to take action on. We are working on signage for the site.
