I encourage you to do some digging using filetype:pdf on a search engine. The amount of documentation available on the SPR is fascinating. From what I found out, turns out the question of SPR design and operational limits is a complex issue to say the least. The SPR is a big system composed of many sub-systems and there are entangled legal, policy, technical issues at play. Interesting stuff!
