Trawsfynydd, in Wales, sta discutendo con NuScale per un sito nucleare ai margini del villaggio.

Una rivalità commerciale

Trawsfynydd è al centro delle trattative con il governo gallese per portare i reattori modulari di piccole dimensioni (SMR) nel Regno Unito. Il sito si trova nel Galles settentrionale. NuScale affirms that it is ready to implement its SMR technology on site.

Il sito di Trawsfynydd potrebbe quindi ospitare la tecnologia SMR, così come il sito di Gwynedd. In effetti, il Gwynedd ha fissato la data di costruzione al 2027. In Trawsfynydd there are three potential sites and they have an agreement with the Nuclear Decommissioning Authority (NDA).

Rolls-Royce SMR and Balfour Beatty hanno firmato protocolli d’intesa per pianificare la costruzione di reattori SMR. Si tratterebbe di reattori pressurizzati ad acqua leggera Holtec SMR-160. L’azienda ha in programma di avviare il processo di convalida normativa nel Regno Unito.

A technology to implement

NuScale maintains that its SMR VOYGR technology is already in development. Non resta che distribuirlo sui siti. Tom Mundy, presidente di VOYGR, ha dichiarato:

“Pensiamo di essere in una buona posizione per poter andare avanti. No è che dobbiamo sviluppare di nuovo la tecnologia e poi portare avanti i progetti”.

Secondo NuScale, il governo ha interesse a sostenere la tecnologia SMR come parte dell’equazione energetica complessiva del Regno Unito. Il design del VOYGR 12 può ospitare fino a 12 moduli di alimentazione NuScale. La produzione lorda totale ammonta quindi a 924MWe.

The NuScale power module is also a pressurized water reattore for steam generation. The integrated heat exchanger in a single unit generates 77MWe. È il primo SMR a ricevere l’approvazione del progetto da parte della Nuclear Regulatory Commission statunitense.
