It shouls be intrinsically safe. The water has a massive heat capacity and is an excellent shield for radioactivity. Also, recovery, if that's what we want, is much easier, as we are recovering a solid material, rather than containing spreading sheen of tens of thousands of barrels of oil.
Nuclear reactors on land have real, demonstrated liabilities, but, in my opinion, the story would be very different over water.
Briefly, water is how we store hot radioactive waste right now. In fact, Randal Munroe of XKCD fame has a great video on spent fuel storage in pools on YouTube here.
Personally, I find difference in safety is so great in favor of the nuclear reactor that I cannot even draw a meaningful comparison. Would I rather drink water from from a spent fuel storage pool or one contaminated with fuel oil? Spent fuel every time. Would I rather live with an off-shore sunk nuclear reactor or an off-shore oil spill? Sunk nuclear reactor, 100%. Which would I rather be in charge of clean-up? Yup: Sunk reactor.
Is there a compelling alternative perspective here?
You're right, being at an 8.5 in anxiety when you think a 4 would be appropriate does not seem great to me. However, knowing this may make for a better target than no anxiety, particularly given the circumstances.
If you are open to it, you might consider the Feeling Good App. Although I have not personally used it, a close and trusted friend was involved with the development of the app. Also, the methods used have been very helpful to me and have also allowed me to help others.
If you try it and like it, perhaps you can let me know. I know that my friend would enjoy knowing that he was part of something that helped someone.
I'd like to say that your choice is praiseworthy. Despite your difficult circumstances, you would rather experience this very painful condition than disregard the people in your life that matter to you.
What if you could have the best of both worlds? What if you could experience the anxiety that has helped you be aware of dangers in an uncertain environment, but not experience such a high level of anxiety that it interferes with your work and sleep?
If so, try figuring out where that more desireable level of anxiety is. This would be two questions: first, on a scale of 1 - 10, where would you rate your current anxiety? (I think we know the answer to that one) second, what do you think would be the appropriate amount of anxiety for someone in your situation?
If you can answer those, perhaps there can be a way to reduce your anxiety without losing the good things about yourself that the anxiety denotes.
You are not alone.
It seems to me that you are having a very reasonable reaction to a difficult situation. If I was in your position, I would also feel extreme anxiety. I know nothing about you, but, from what you have shared, I would like to commend you for your anxiety. It is evidently clear from what you write that you take your responsibilities to your employer and your family very seriously. A nonchalant attitude in the face of a life-changing event like the one you are facing would belie a lack of concern for the people closest to you, who depend on you and whom you care for.
These appear to be serious matters and you are taking them seriously, even to the extent that it causes you some extreme discomfort. This is a commendable commitment to duty and to the welfare of others.
Suppose there were a magic button that could make the anxiety disappear, however it would also cause the motivation for that anxiety - say, love, duty, commitment to excellence - it would make these also disappear. You would no longer be bothered by your precarious position, but you would also become someone unconcerned with their own wellbeing and the wellbeing of those around them.
If you had such a button, would you push it?
I'd also like to point out that the underlying model may well be unsustainable in the way that it is offered at the start. Who benefits when a for-profit company operates at a loss? We, the customers, do. We get low prices and customer-friendly practices that are genuinely enjoyable. That business can't operate in that way indefinitely, as the early investors are not funding it as an act of charity.
Eventually, the bill comes due. The shareholders have funded the company on the premise that, after losing lots of money on customer acquisition, it can restructure and monetize those customers and recoup their investment, hopefully with a lucrative return when they decide to capitalize their holdings and find a new company with which to repeat the process.
There is absolutely no reason not to enjoy the perks of the early stage of the customer acquisition process; the shareholders are subsidizing your product at no cost to you. But we shouldn't be surprised when the shareholders stop subsidizing and start squeezing their formerly pampered customers in the hopes of getting their money back (and more, of course).
This doesn't excuse unethical or abusive practices, but it does mean that, even without them, the experience of those early days probably wasn't going to last forever.
As a preliminary test, you might look at a "sleep apnea adjustable mouthpiece" for sale online. I don't know how well these work, but my custom sleep apnea dental device has been amazing for me. It may be that the boil-and-bite varieties also work well. If so, you might get relief without having to interact with the healthcare system.
You might find more information here.
As for the sleep test, many factors are important, but you could learn a lot from monitoring your pulse oxygen while you sleep. A casual search turned up several very affordable fingertip pulse oximeters that connect via Bluetooth. This would let you create a record of your pulse oxygen levels while you sleep. If you are dropping below 92% while you sleep (link), then you might be sleeping poorly because of sleep apnea.
In fact, you could record your SPO2 levels with and without the sleep apnea device to rule its use in or out without spending a ton of money on doctors visits and the like.
I hope things get better for you.
For anyone who feels this way after waking up from what should have been "enough" sleep, consider getting a home sleep test. Going from moderate sleep apnea to none was life-changing. If this is how you feel regularly, it doesn't necessarily have to be this way.
Hey, what are the exact dimensions of the part with the thermal paste? I'd be curious know just how much area is being covered.
Some friends of ours strapped down their roof for Hurricane Georges. They lived in a wood frame house on a hill and knew better than to just trust that everything would be ok.
Anyway, they still had a roof after the hurricane, but the winds were still strong enough to lift the roof up, damaging the joints between the rafters and the main posts holding the roof up. This damage I saw with my own eyes.
Wind shear can be remarkably strong at 140 mph, blowing across a roof like that. It would be a shame to lose the house because you didn't take two hours to put some straps over it.
