Ma loen ikka, et 14 mlrd tuleb mõlema reaktori kohta kokku.
Ahjaa, vabandust. See oleks juba päris hea saavutus, võrreldes seniseid tulemusi.
Teise teema jätkuks,
siin on nati rohkem infot sellest elektron-kiire keevituse uudisest. Tundub et põhiareng on see et enam ei vajata vaakumkambrit selle töö jaoks:
Using EBW, the company weld-joined two 200 mm thick, three-meter diameter vessel sections in UK-SMR nuclear grade steel. The weld, equivalent to approximately 10m of length, was completed in a single pass and in a dramatically short timeframe.
Completed in 140 minutes, with no reportable defects shown in preliminary non-destructive testing (NDT), offering a radical breakthrough in welding technology. A weld of this kind would typically take months and include numerous stages of NDT as well as heat-treatment.
Research, Design and Technology Director, Professor Jesus Talamantes-Silva, said: “This is the most critical milestone in our project to industrialise EBW and to eliminate the requirement for large vacuum chambers typically used in this technology, we have pioneered the use of local vacuum EBW alongside our project partners, Cambridge Vacuum Engineering (CVE).”
Redditist hea kokkuvõte:
The eli12: this was done by putting a single beam all the way through 2 thick plates of metal pushed right up against each other, while conventional welding with filler material needs an approximate fuck ton of passes because some amount of one or both plates carved out at an angle to make a weld joint that needs to be filled in with weld. Conventional welding process can do feedstockless (autogenous) welding, but it’s limited to much thinner sheets than this because the heat dissipates and you end up with only a portion of the thicker plates welded together. EBW has always been capable of doing these types of thick autogenous welds, at least when you have a powerful enough electron beam source, but it’s been limited in deployment as it previously needed a vacuum chamber big enough for your part
Tundub üsna huvitav läbimurre mis peaks võimaldama omajagu teistsuguse disainiga surveanumaid kui praegu.
Siin veel üks artikkel piltidega:

Sisuliselt keevitati siis kokku kaks 200mm teraskomponenti ühe keevitusega 140 minutiga, vajamata vaakumkambrit ning esmaste (ultraheli) uuringute järgi tuumajaamade standarditele vastavalt
Ehk keegi keevitusega rohkem sinapeal kaasfoorumlane oskaks midagi kommenteerida. Ise ei oska hinnata kui suur see saavutus siis on
nojah mai ei tea! Igaljuhul käsi ei tõusnud artikli lugemise eest maksmiseks. Guugeldasin autorit, ega midagi eriti välja tulnud. Väidetavalt insener ja mitmete erinevate firmade juhatusse kuulunud, aga palju erinevatel teemadel targutamist ajakirjanduses.
