Thanks to another aNONradiator, stug, host of “Flux” (Thursdays at 2000 UTC), I spend most of the show ruminating on the process of engineering design. In the process, I give a word–picture of my own pet design for a small nuclear “package power” plant, suitable for ship propulsion or modest shore–side requirements. Also, a change in policy on the part of data center operators which is really little more than a change in framing ; and the question of what constitutes “sustainable” aviation fuel.

Closely– versus loosely–coupled systems, as illustrated by two different nuclear power plants ; the possibilities of orbital data centers ; the continuing travails of the Boeing CST–100 “Starliner” ; an update on my travel and exhibition plans for the summer ; and Mail Call! If you want to send me mail, don’t feel that you have to use invisible ink.

Must nuclear projects always take longer and cost more? Ontario’s Darlington refurbishment says “no”, and I venture to suggest that this should be the expected result. Also, a listener comment elicits a digression into the problem (if it is one) of weapons proliferation and the plutonium economy ; a reminder that Famine is the harshest of teachers, and the lessons of ecology have been learnt primarily at her hand ; and I address a misconception about grid frequency control, and wonder about on–line enlightenment.

Despite delays in the mails, we have Mail call! Also, progress with one of my many “Man and Atom” information efforts — remembering Anita Gale of the National Space Society and Ed Stone of JPL (yes, Voyager has now outlived its Chief Scientist) — Islets of Langerhans! — and a meditation on what we are as human beings, and the value of considering that very question, prompted by another instance of Big Business resembling a mental illness.

  • 2024–06–18 After some reading of bits I am composing for a second issue of blast, I begin reading A Second Nuclear Era : Prospects and Perspectives by Alvin Weinberg, from The Nuclear Chain Reaction — Forty Years Later (RG Sachs, ed), the Proceedings of a University of Chicago symposium commemorating the fortieth anniversary of the first controlled, self–sustaining nuclear chain reaction.
  • 2024–06–21 Despite interspersing my copious commentary, I succeed in finishing A Second Nuclear Era just short of the end of the hour.

ASFO 2024–06–08

Nico–Clean? What in the world? Also, the engineered physical systems which make life in the modern world possible (often prosaically called infrastructure) and the obligation to keep them up ; the value of immigrants and refugees, and the stupidity (quite separate from any moral or human–rights arguments) of refusing them ; and a lesson, in the context of Internet social media, in cause and reasonably–foreseeable effect.

Supplementary Shows

  • 2024–06–11 Probably the last I will read from The Fast–Neutron Fission Breeder Reactor, Energy for 1000 Years by TN Marsham FRS, the succeeding general discussion, and concluding remarks by JG Collier.
  • 2024–06–14 From ATOM 134 (1967 December), a eulogy for nuclear pioneer Sir John Cockcroft, and Electricity from the Atom — Britain’s Second Decade by ES Booth.

A "Nico-Clean" card in its original packaging. Price 1000 yen.
If you want one of these things — or ten of them! — do let me know.

More on “blast” and further efforts with payphones ; aspersions on the US education system ; a US Government press release which may be good news for nuclear, but not for anyone hoping for scientific and engineering literacy among the policy–making class ; and a somewhat abstract and poetic thought about one of the intersections of politics with engineering, in which I use the phrase “touched by the finger of Vulcan”. (Start is just slightly late.)

Supplementary Shows

  • 2024–06–04 Again from The Fast–Neutron Fission Breeder Reactor, I go back to the beginning of Engineering and design of fast reactors by Köhler and read the whole thing, and then some “General Discussion”.
  • 2024–06–07 More from The Fast–Neutron Fission Breeder Reactor : Environmental aspects of the fast reactor fuel cycle by GM Jordan and LEJ Roberts FRS. This is a bit less accessible, and narrowly-focussed on radioactive discharges to the environment, but the basic conclusion that most of the environmental impacts of atomic power are associated with uranium mining, and thus reduced 100-fold by the regenerative fuel cycle, seems clear enough.

Can I solve all the problems of the Japanese economy? Absolutely not. But I might make a few suggestions as to how to reduce fuel use, to the benefit of the balance–of–payments and the value of the yen, and at the same time relieve the pressures that drive people from the rural areas to the cities. Also, US Customs and Border Protection leads me to talk about the problems of Internet social media, which is usually far off my path, and make comparisons with other forms of communication ; and a little bit of capitalism and its discontents. Also, a final version of blast №1 is now available (with extensive commentary).

2024–05–31 From The Fast–Neutron Fission Breeder Reactor, the Proceedings of a discussion meeting held 24 and 25 May 1989, reprinted from Philosophical Transactions of the Royal Society of London (Series A) : Introductory remarks by RS Pease, FRS ; The science of fast reactors and why it has been studied, by G Vendryes (CEA) ; and just the first little bit of Engineering and design of fast reactors by M Köhler (Interatom). Unlike The Breeder Reactor, this is not intended for a general audience, but as it is meant for the non–specialist, at least parts of it should be reasonably accessible, and those are the parts I mean to read for you.

Did you see the Aurora Borealis last night? It was visible quite far south. (There was Aurora Australis too.) Economists (not for the first time) get the sharp edge of my tongue as I reflect on one of the world’s most baffling megaprojects, “Neom ‘The Line’”. Also, Mail Call!

Dragonfly, the probe–aircraft which NASA has decided will soon be sent on its way to Titan, the giant moon of Saturn, is in my thoughts today. In particular, I want to know where the plutonium–238 for its thermoelectric power source will come from. Otherwise, I mostly discuss my travel plans, both for returning to the USA and for this autumn ; Deutsches Museum, one of the greatest science and technology museums in the world ; and the curious railway station at Eisenstein, where the border between Germany and the Czech Republic is halfway along the platform.
