Yield

Well, first, there is a suggestion of improving the infobox, but the given yield doesn't match any of U233, U235 or Pu239 given in the article. Gah4 (talk) 06:41, 1 January 2023 (UTC)[reply]

@Gah4: There's no yield in the infobox. Do you mean the value in {{Medium-lived fission products}}, which is noted to be a weighted average of 65% ²³⁵U and 35% ²³⁹Pu? ^Complex/_Rational 16:41, 1 January 2023 (UTC)[reply]

There is the further explanation needed, which it would seem to include the 65:35 mix. Gah4 (talk) 17:55, 1 January 2023 (UTC)[reply]

mass

I suspect this question should go to the infobox page itself, but could we have the actual mass in it? Gah4 (talk) 06:42, 1 January 2023 (UTC)[reply]

Done, sourced to {{AME2020 II}}. Also, for isotopes (unlike elements), the infobox is in the article, so this talk page is the correct place to ask. ^Complex/_Rational 16:47, 1 January 2023 (UTC)[reply]

It seems that there is a question on the difference of the binding energy for Sr90 and Y90. The difference is small enough, that you have to calculate carefully, and some people don't do that. Gah4 (talk) 17:58, 1 January 2023 (UTC)[reply]

Waste Classification

A claim in the "Nuclear Waste" section alleges that Sr-90 is intrinsically High-Level Waste. This is incorrect - Sr-90 is a component of High-Level Waste inasfar as it is a fission product present in spent fuel, but Sr-90 in non-fuel sources can be defined as low-level waste, to the point where Sr-90 is one of the determinants for the classification of what low-level waste (See table 2)

Does anyone know what Wikipedia's standards are regarding regulatory definitions? I imagine some regulatory setup could classify any Sr-90 as HLW, but as written this seems inconsistent with the US NRC's regs and the IAEA recommendations Skeejus (talk) 18:12, 9 February 2023 (UTC)[reply]
