The idea was to streamline the processes so that nuclear energy would be ”in line” with other energy sources, with appropriate steps in decision making. But no worries, there’s quite a lot of requirements, still. If you look at the proposal, these are conditions for construction permit alone.

Confusion might be from ”technology neutral”, which means there that SMRs, traditional large plants, gen4 stuff should be handled similarly under this same legislation.

Not that it should be same as for renewable energy.

Where do you find the statement that building SMRs would require same processes as RE plants?

The intention has been to separate political decision from lower level technical and EIA stuff.

Not that there would be no strict regulations.

Where it is claimed that same permits are needed? E.g. requirements for construction permit are much stricter. See screencap.

I think there are many false interpretations going on, especially due to bureaucratic language these are often written in.

IF someone puts up the money and effort to create the ecosystem, THEN they become easier investment for customers. There’s the cost barrier up front. (Like in all industry, I guess)

Same goes with e.g. nuclear shipping. Individual ships, why not, when someone has built the infrastructure.

Trying to find ways to keep OPEX down is why I was claiming that fleet operation model and relying on operator of existing large NPPs would be the way to go. Small SMRs can’t operate with the logic of stand-alone power plants.

Pilot plant is a bit misleading term. It’s a thermal hydraulic test system to test the key safety system (and potentially something else; I’m not involved). But a plant it is not.

But that’s a perfect name.

Before:
”I want one drink, please”
*sneer* ”and what kind of drink?”
”…I don’t know cocktails…” *disappears behind the counter*

Now:
”I want one drink, please”
”Here you are!”
*happiness*

”substantially advances human knowledge in an interesting direction”

That’s no PhD, that’s a Nobel laureate.

Mukana ei yhtään maata jolla yhteistä rajaa Venäjän (pl. Kaliningrad) kanssa. Suomi ja Balttian maat jätetään tuossa vähän ikävään väliin kyllä.

Naapuri tuossa kommentoi pörssisähkön hintoja että ei teilläkään sähköauton lataaminen kivaa ole jos hinta kuuttakymmentä senttiä kilowattitunnilta. Vastasin siihen että niin siinä oltaisiin hetkellisesti samassa kuin hänen bensa-autollaan joka päivä…

Lets assume 20 Sv at 25 m, it would be a little above 140 mSv at 300 m, ignoring shielding. Tank crew might be more cooked thanks to neutron activation of all that metal. That activation might be a big factor here…

But with some assumptions, might be trueish. Would not like to test it, though.

The notice seems to note that all member states adhere to nuclear nonproliferation treaty, and specifically also notes that established nuclear states at the time of NTP signing are exempt.

So, French weapons investments are specifically sustainable?

Iranilais-kanadalainen työkaveri on vakuuttanut mut perinteisen persialaisen kalenterin ylivoimaisuudesta: vuosi ja päivä vaihtuvat uuteen päivään tasan kevätpäivän tasauksen aikaan. Tällä saadaan kalenteri seuraamaan aurinkoaikaa automaattisesti ilman temppuiluja karkauspäivien kanssa.

Today -15 C, forecast for the new year -27 C. Fortunately ice is a good insulator.

Alas! they cannot translate the copious use of Alas!

Well, I mean, few of those boys became obsecenely rich and got to rule the world. And then got mad that not everyone was worshiping their supreme intelligence, and decided to torch the place.

And that’s (part of) the problem now.

Also, in places, it ends in fire. As it always does.

Ben Zyskowicz kutsui Ylen haastattelussa sunnuntaina väitöskirjaohjattavaani Bruno Jänttiä "Hamas-aktivistiksi". Väite on täysin valheellinen. Jäntti on toistuvasti kritisoinut Hamasia. Terroristijärjestön aktivistiksi leimaamisella voi olla vaarallisia seurauksia. 1/3

Olin 2003 sivarissa ilmatieteen laitoksen yläilmakehän yksikössä, ja siellä noita avaruussään vaikutuksen tutkijoita oli. Jännä miten nyt lentokoneiden ohjauslaitteesta moisia vaikutuksia löytynyt.
