Any improvements I can make to these designs? Was going for a general throughput reactor with balanced EU/t and efficiency.
Reactor 1 - 401 EU/t 
Reactor 2 - 425 EU/t
Essentially the same reactor, but one uses an extra plutonium. Should probably run them at 40 second cycles as well, but running mark V is dangerous enough without components nearly dead. I also had this at 450 EU/t, but the ratio of plutonium to to thorium doesn't seem manageable.
 
		 
		
		
	 
															
		 
   
  
 
  
 but I don't see any way to get the cooling needed to make a Mark 1 reactor.
