Particularly there are a lot of inconsistencies around the technology and the way it functions. The most famous example being "stackpoling."
I actually wonder about the very first "Stackpole."
The reason this is, is while working on some lore searches for weapons, I noticed while digging through the Macross-inspired mechs that the Warhammer specifically mentions a Fission Reactor in the blueprint.

Point "V".
Now what makes this interesting is Stackpole's first novel is 1988, this blueprint was made in 1987.. and during this time, books make references to both Fusion and Fission engines as, like many things... it was
NOT set in stone yet. Contradicting information in early versions of the Battlemech Manual compared with the BattleTechnology magazine and the 20-ish years later Tech Manual also shows many other changes.
The BM makes a few references to Fission Engines. BattleTechnology never once mentions Fission. The Tech Manual mentions both but unlike the BM it doesn't make the mistake of using them interchangeably. As such, it is possible (though I don't know for certain as I haven't read the first "Stackpole") that he was thinking of a Fission Engine. Even if he wasn't, I'd make an argument that pretty much nobody knew that a ruptured fusion reactor is extremely unlikely to go nuclear. (To be clear it can, but you'd have to do it during the reaction which for a theoretical Fusion Reactor is not constant. In truth neither is Fission and the same conditions need to be met, an explosive disruption during the reaction.
According to
https://www.eia.gov/...lear_fuel_cycle
from 1968 to 2013 (45 years) at 118 nuclear reactors, 241,468 fuel assemblies have been discharged (used).
241,468 / 118 facilities = 2046.338983050847 used per facility as an average. Now, divide by 45 years, and its pretty much 1 fuel assembly consumed per year per facility. (Unfortunately that's an over simplification and assumes all reactors existed at once, the same document shows that every 1 to 2 years they cycle out 40 to 90 fuel assemblies.) According to the same site, a fuel assembly takes a few years to cool off before it can be moved. Their reaction is controlled by control rods which help regulate the size of the reaction in the water.
Technobabble aside, reactions are not constant, and in both Fusion and Fission reactors a nuclear explosion pretty much can't occur through the means of a violent rupture unless it occurs during a reaction. So Stackpole is both possible...and extremely unlikely, and if what I remember hearing about a Stackpole being done deliberately to use as a suicide bomb is correct... pretty much isn't gonna happen that way. Similar to a Roach only being vulnerable to radiation only 10 to 13 times in its lifespan (during the molting process when the cells divide), a nuclear explosion is only likely to happen if the fuel rods are ruptured during the process of a reaction.
TL;DR: Stackpole might've been not only been thinking of Fission engines but actually could have been describing a Fission reactor stackpoling as at the time Battletech kept using both Fission and Fusion interchangeably in its early fluff. Warhammer's blueprint expressly states it is using a Fission reactor. Regardless, stackpoling is thereotically possible for both types, however unlikely with Fission and extremely unlikely with Fusion.

I've found the "Fission" reference to be explained away in something rather obscure from 1989.
The Fusion engines contain a small Fission igniter.
The shorthand of this obscure piece of fluff is this:
Fusion reactors require an absolutely immense amount of power to start. Power that likely won't left over after performing an immense alpha strike that has shut down the reactor. A small Fission "igniter" (did they mean ignition?) acts as a kind of alternator or jumpstarter for the Fusion Engine in order to overcome the Coulomb Barrier and start the first fusion reaction.
The amount of heat required to start a fusion reaction in real life is virtually unfathomable, leaving only particle accelerators as a means to get that reaction, and that leaves what powers it enough to get the initial Fusion reaction? Apparently, a Fission reaction that can boot a hot machine "in about 7 seconds." Course, that makes me wonder about cold starts. The King Crab bootup sequence in Storms of Fate seems to take several minutes. No wonder there's frequent depictions of mechs trying to get out of hangers as the hangers are destroyed.
Sadly as this literally is not mentioned anywhere else as far as I know of, it's hard to consider this canon despite how it makes sense and makes stackpoling more likely to be plausible (as well as even expressly pointing out the best time to strike to get a stackpole on purpose in a way that is even scientifically accurate).
(I meant to share this discovery in one of my owns threads, but it came out here.)
(Can't believe I had to make an edit just to put the word not in.)
