Hello ColHut,
The short answer is -
The Jump drive requires the hydrogen, which is canon established in Classic Traveller, to open the jump portal after the jump capicators have been charged by the output of the, in this case, fission power plant.
The long answer -
Here is the skinny on fuel requirements.
There are two, or four if using the HG optional maneuver drive and power plant rules, Traveller systems that require fuel.
The jump drive requires, for optimal results, refined hydrogen and a huge amount of electrical power for interstellar travel. Per the Core Rulebook the tankage required is for the maximum jump range.
A Fusion Power Plant uses either refined or unrefined hydrogen to provide power to the jump drive's capicators, generate power for the gravitic M-drive and other systems. From the Core Rulebook the fuel requirement is for a 2-week operating period.
The fission power plant option requires radioactives. The Core Rulebook's fuel requirement table shows the required d-tons for a year. HG amends the d-tons and cost to 2 times that of the standard fusion power plant.
HG introduces the reaction maneuver drive and chemical power power plants which require more fuel tankage than the standard options.
Hope this helps and is clearer than mud;-)

You assume correctly.
For MGT, Core, pg 109 and High Guard, pg 42 amends - same power as fusion at twice the tonnage and price.
[Though, I consider this rather broken IMHO].
I am not sure I was clear: Can you use radioactives (fission) fuel for the Jump drive...or must you consume Hydrogen from Hydrogen fuel for the Jump bubble?
cheers
