  • Personally, I’m not offended when referred to as ‘-sexual’. In general, I don’t see my gender as an important part of my identity. I guess I’m ‘just’ cis male but I don’t see that as restrictive in any way.

    But thanks for your explanation! Good to know that there’s a negative connotation tied to that term and other people might be offended. I’ll try to keep it in in mind for future discussions. :)







  • I use Lemmy a lot to debate or read other people’s perspectives. While content is more important than the vote count, I’m still interested to see what are (un)popular opinions here (knowing that it definitely doesn’t represent the general public!).

    Unfortunately, seeing the votes immediately also increases your bias towards posts or comments, so it may have a negative impact on on your individual free thinking.

    An ideal compromise for me would be to see how other people voted, but only after I voted myself.








  • Indeed my previous statement seems to be a bit outdated. Modern nuclear plants seem to be more flexible than those in the past.

    Historically, nuclear power plants were built as baseload plants, without load following capability to keep the design simple. Their startup or shutdown took many hours as they were designed to operate at maximum power, and heating up steam generators to the desired temperature took time.[2] Nuclear power generation has been also portrayed as inflexible by anti-nuclear activists and the German Federal Environment Ministry, while others claimed “that the plants might clog the power grid”.[7] Modern nuclear plants with light water reactors are designed to have maneuvering capabilities in the 30-100% range with 5%/minute slope, up to 140 MW/minute.[7] Nuclear power plants in France operate in load-following mode and so participate in the primary and secondary frequency control. Some units follow a variable load program with one or two large power changes per day. Some designs allow for rapid changes of power level around rated power, a capability that is usable for frequency regulation.[8] A more efficient solution is to maintain the primary circuit at full power and to use the excess power for cogeneration.[9]

    Nevertheless, I am very sceptical regarding the technology. I think our primary target should be to lower the overall energy consumption. And then we should try to reverse the logic and instead of production following consumption, to have consumption follow production. With smart grids, heat pumps, electric cars, thermal storage systems etc. we have many instruments to flatten out peaks in demand.



  • I agree. An open discussion should be as complete as possible and ideally consider all relevant aspects.

    From my perspective, the time perspective in context of nuclear waste is really significant. Until we find a clean solution to fully recycle or dispose nuclear waste, there are almost infinite maintenance efforts even ignoring the danger of the waste itself.

    If we want to monitor the potential radioactive pollution around where the waste is stored, it means roads, elevators, protective doors, sensors, measuring systems, protective gear etc. have to be constantly maintained and renewed. We must upkeep the monitoring for 1 million years until the waste is no longer dangerous.

    How long is the lifetime of this equipment? Even if we assume an unrealistic lifetime of 100 years, it means we have to renovate all storage facilities 10000 times. 10000 new elevators, 10000 new roads etc.

    1 million years is just a completely insane period of time and we have no clue if we really ever find a safe way to deal with this stuff. So people in the future will have to do all this maintenance even if hunanity stopped using nuclear power tens of thousands of years ago.

    And that’s just the pollution directly caused by maintenance. If there’s an accident while installing a new elevator and radioactive material is released, we have way bigger issues.


  • Why does safety only consider air pollution and deaths? The most concerning aspect of nuclear power IMO is the nuclear waste. There is still no safe way to permanently dispose or store it. In Germany we store nuclear waste in salt caves that were meant to be a very stable system. But already after a few decades we find leaking barrels and contamination of groundwater reservoirs.

    This contamination will keep getting worse for hundreds of thousands of years and may have negative health impact on humans and animals.

    Just because it doesn’t pollute the air right now, it doesn’t mean it’s safe.
