Process Improvement Transition Authorization IP-20-I: Increased graphite temperature limits and use of nitrogen in the K reactors

The objectives of this Process Improvement Transition Authorization (PITA) for KE and KW reactors are to authorize a flat 700 C graphite temperature limit in the bulk of the graphite, with a conditional 850 C limit in the 0.130 coring zone only, and in conjunction therewith to provide for routine use of nitrogen instead of carbon dioxide in the reactor atmosphere. These temperatures as quoted apply to filler blocks in the vicinity of normal channels, and are maximum limits.

Reactor thrust during boost in a high altitude trajectory

Reactor startup of a submarine based missile must be accomplished during boost., so that at burnout the reactor maximum wall temperature is at or near the design value. Because cooling air must be supplied during this period, there exists the possibility of obtaining some thrust to augment the booster. To find how much reactor thrust might be available, a representative high altitude boost trajectory was selected. This is shown together with an estimated pressure recovery curve for the inlet.
