(tidal power)

Not on anything like the scale you are discussing. UK peak demand is
60GW.
Total global tidal power is 0.3GW. Total global nuclear power is around
370GW.

24/7 production,

Only notionally. It varies with the tides and peak production may not be
when you need it.

With two sources (Morecome Bay and Severn Estuary 24/7 is easy, and will
produce moer GW than any single nuclear plant.

They are not lagoons.

It /will/ modify marine environments. They change anyway. I can't see any
overall worsening.

Yep.

The life of a tidal barriage (or lagoon) would be extremely long. Its
construction would not be difficult, and relatively pollution free. A
win-win
situation once the nimbys are consoled.

Yep.
