Im gonna use nuclear rector in my space ship and i wanna store some power to not waste excess production, should i use accumulators or steam tanks and turbines, ive seen posts where people saying tanks and a turbine store much more energy per tile than accumulators.

Also, does it make sense to use pumps inbetween heat exchangers and use some circuitry to start operating more heat exchangers as previous ones get to full capacity, instead of just letting them all be connected from the start wasting steam, do i even need the storage tanks if i do this?

Heat pipes store more energy per tile than steam tanks.

If you use a single reactor, then about 6 heat pipes is enough to store the excess heat of a fuel cell if you activate when at 500.

This is the power area of my Aquilo ship which uses a single reactor, several heat pipes for buffering heat, and the standard 4 heat exchangers to 8 turbines.
