I’m not absolutely sure what reducing a valve signifies… but as an alternative of cutting the valve on the era unit that was shut down, they slash the valve on the generation unit that was even now running!… And this seemingly nearly precipitated a shutdown of the working device at Koeberg… and is explained in this e-newsletter as a really critical incident.

“… simply because it experienced the possible to amongst other threats, drain the accumulator of the Basic safety Injection Program tank 1 RIS 002 BA… It could have experienced devastating repercussions.”
Koeberg purchased a perform stoppage to consist of the circumstance.
It virtually shut down the total plant simply because fifty percent the plant is shut down… The other 50 percent could have been shut down as a consequence of this incident which could have taken 1,800MW in overall off the grid at a time when we had load shedding.
