They were both completely and utterly wrong
![]() Anyone can be a self-professed expert, but even more so in the 80s before easy access to information to fact-check. Quote:
The products also have low atomic numbers, albeit higher than the individual fuels. Helium-4 (which is actually just common helium, >99% of naturally occurring isotopes, and a typical fusion product) has an atomic number of 4. Plutonium has an atomic number from 238 to 244 depending on the isotope. Elements heavier than iron (atomic number 26) are not usable as fusionable fuels. Quote:
Learn a bit of basic design theory, systems can fail badly (meaning a failure mode can/will place it into an inconsistent, unpredictable or dangerous state, compromise operations or some other undesirable consequence), or they can fail well (in the context of safety systems, typically when they will stop by themselves and operational systems have to actively PREVENT this, a common example is the dead-man's switch used on various machinery, or an electromagnet that holds a contact open - if it, the supply or control system fails, the contact closes).

http://www.newton.dep.anl.gov/askasc...9/phy99554.htm A reactor is barely critical and controlled by graphite moderators and neutron poisons (and indeed, fails to an inert state without oversignt); a bomb is a critical mass held barely subcritical so that any further introduction (normally a compression) will cause a spontaneous criticality, with no control and with neutron-reflective materials to increase the rate over time. Also, at the risk of going off topic, I want to ask just what weapons have to do with this topic? I know you won't be able to answer though; that's like complaining about electricity because railguns are in development/theoretically possible, or the wheel because tanks use them too, or fire because if someone is stupid enough to put their hand in it, they will get injured. It's a red herring argument. Quote:
![]() Even if humans did magically disappear, the entire point is that without operation, the criticality is lost.
