There are two nuclear power stations there now. Apparently there are
two possible reasons for the tsunami& it could happen again.

Are they tsunami proof?

What do you not understand about UK stations being of a different design
from the BWR in Japan and not needing the pumps that were the only
critical thing damaged by the tsunami?

The pumps and the standby generators. And when they did ship some generators
in the plugs weren't right.

Strictly speaking, the pumps were not damaged, only the generators to
power them. The pumps ran for eight hours on battery backup. However, I
was trying to simplify things to make them easier for Harry to
understand and the point I was making is that our power stations do not
need the pumps in the first place.
