Question about cycles

A cycle is the time it takes for a uranium cell to run out of power, so if a reactor can run 1+ cycles you can put in your uranium and leave it until it runs out (make sure you let it cool off before refueling). I think a uranium cell lasts for about 1 million reactor ticks- no idea how many reactor ticks in a second.

Uranium cells last 10000 reactor ticks and you get 1 reactor tick per second, so a uranium cell can be used for 10000s (2h 46m 40s) before running dry.

Cycle length depends on your reactor - some (Mark 1 and Mark 2) reactor designs can run for a full cycle before overheating, so 1 cycle is 10000s. Other reactor designs (non-CASUC mark 3, 4 and 5) need breaks, so the effective cycle time is increased. For reference, my house on the server I play on has the Mark 3 reactor listed in the good reactor design thread installed. It runs a 5s on, 25s off duty cycle, so the effective cycle time (defined as how long I can leave the switch on before it needs to be refuelled) is 30/5 = 6 times longer, or 60000s (16h 40m).

Says here theres 20 ticks per second.

That is indeed the case for energy generation, but not reactors. Confused the hell out of me at first, but one reactor tick happens every second (in the code, reactor state changes happen every 20 world ticks and since there are 20 world ticks per second...) - see here: http://wiki.industrial-craft.n…php?title=Nuclear_Reactor.
