I guess – eng technesch Limitatioun ass et op jidde Fall net. An déi 400kg kann een natierlech och als Verhandlungsmass huelen

Vlt och interessant: Wisou 60%, dat ass eng komesch Zuel. Wier theoretesch waffefäheg, mee ontypesch. Little Boy hat schonns ~80%, hautzedags geet een dovun aus dass all Uran-Waffen iwwert 90% sinn.

Technesch wier dat keen Défi: een deen op 3% ureechere kann, kann och op 20, 60, 90% ureecheren.

Am Prinzip jo.

E puer Ausnamen: Fir Forschungsreaktoren, U-Boot/Schëffsreaktoren a Produktioun vu medezineschen Isotoper (fir zB Kriibsdiagnosen, mengen ech) kann een och ~90% ugeräicherten Uran notzen. Et ginn awer och Alternativen mat ~20% Uranuräicherung.

RISING LION and MIDNIGHT HAMMER have not slowed the Iranian program nearly as much as the JCPOA. We hold diplomacy to much higher standards than bombing. The same people who endlessly complained about the JCPOA "sunsetting" are now happy to delay Iran's bomb by much less. 15/17

Luxemburg-Stadt / Ein Sieg für die Transparenz: ZUG gewinnt Zebrastreifenstreit gegen Gemeinde Luxemburg Ursprünglich ging es um die Sicherheit an Zebrastreifen, später auch um Transparenz.

Kremlin and Trump aides raise nuclear war fears after Ukraine drone strike Vladimir Putin has warned Russia will respond to Kyiv’s attacks on nuclear-capable aircraft at airfields

Oh, ffs.

I continue to assess risk of nuclear weapons use by Russia, in, over, about, or on Ukraine as low, high confidence, (ceteris paribus) shirt- to mid-future.

A)
If you don’t want your nuclear capable planes to be targeted then don’t use them to invade your neighbor.

B) bombers

Sinn net iwwerzeegt vun där Logik. D'Leit wëllen dach net an de Krich well se Angscht em hiert Liewen hunn, an net well si an der EU e gutt, "subventionéiert" Liewe féiere kënnen – dat steet d'ailleurs ee Saz virdrun am Artikel?

Gott a wuel och e lëtzebuerger Geriicht. 🤷🏼‍♀️

2025 Fellows Scheme Applications Now Open! Are you interested in researching and having impact in nuclear arms control and disarmament? Do you want to join a community of scholars and practitioners exploring innovative ideas in the field of…

Hey #nukesky, there's still time to apply to the Atomic Anxiety in the New Nuclear Age Fellows Scheme!

The application is super short, so if you know any early career researchers, policymakers, or practitioners who might be interested then please share widely!

🚨 4️⃣ positions to be filled! Join us in Frankfurt/Darmstadt for exciting work in #nuclear arms control, nonproliferation and disarmament at the crossroads of #science and policy! DLs mid-December and later, vary per position. Working language English. And we move into new fancy office spaces! 🚨

Kann et sinn, dass d'Audiospuer net verfügbar ass? Weder an ärem Link nach an der Mediathéik?

Could you please add me? Thanks!

Right, I use roundabout the same temperature. 30 to 40 min in the Dutch oven with the lid on, then with the lid removed (very roughly 15 to 20 min, until the desired degree of browning is reached).

I am still wondering about how altitude comes into play.

How long are you baking the bread and at which temperature?

Typically, v high temperatures result in a golden/brown/black crust (depending on baking time) which "seals off" the inner part of the bread and prevents drying out. In that sense, I'd be more worried about baking long at lower temps

I need some unfollow Starter Packs

This work also shows that NFC simulations can be used to perform robust, transparent and reproducible fissile material estimates which can easily be updated when new information becomes available.

Graphs showing the total plutonium and HEU production for the three different scenarios

We find that by the end of 2022, Pakistan could have produced 370–660 kg plutonium and 3090–5540 kg HEU (depending on the scenario); and that the once-through NFC is increasingly unlikely.

Graph showing the simulated median HEU production from 2010 to 2033.

In the NFC w/o uranium recycling, Pakistan would have to stop HEU production around 2015 bc. of uranium shortage (dash-dotted blue curve).

In the models w/ uranium recycling, HEU can be produced alongside plutonium (solid orange and dashed green curves).

👉1st scenario is a once-through nuclear fuel cycle (NFC) with no uranium recycling.
👉2nd scenario: 1st NFC + irradiated uranium gets recycled and enriched to HEU
👉3rd scenario: 1st NFC + irradiated uranium gets recycled, mixed with HEU to 0.72% and reused as reactor fuel

Pakistan is reported to have a natural uranium shortage, but has also expanded its nucl. programme (👉3 new reactors). To investigate this contradiction, we developed 3 different scenarios + modeled them with the simulation softwares Cyclus and Serpent2.

Assessing Pakistan’s Fissile Material Production Reports suggest that Pakistan’s indigenous, military nuclear program faces a natural uranium shortage, limiting fissile material production. However, Pakistan has recently built three new plutonium...

I am honored and thrilled to share that I have been invited to join this year's Nobel Laureate Meeting in #physics #LINO24 . Looking forward to meeting many young physicists from all over the world!
Also thanks to VolkswagenStiftung for nominating me.
