S. Korea halts two more reactors over faulty parts

South Korea on Tuesday shut down two nuclear reactors and delayed the scheduled start of operations at two more, prompting government warnings of "unprecedented" power shortages.

The latest move, part of a widening investigation into a scandal involving parts provided with fake safety certificates, means 10 of the South's 23 nuclear reactors are currently offline for various reasons.

Axil is a fan of making big statements, which he cannot actually support with his links, such as that the South Korean plants are not reliable, when in fact they are very reliable.

The current focal point of the regulators is to demand inhuman levels of quality control in each step of the process from fabrication to installation to operation. The level has increased so much, through regulatory ratcheting, that suppliers can no longer comply with the endless documentation and resulting delays if even a tidbit is out of order (even if it's not safety relevant).

We are headed in the wrong direction and asking for falsification of certificates with the current system. It is also hostile towards innovation. The South Koreans have copied the technology of LWRs, but have also copied the licensing focus, unfortunately. Ctrl-a, Ctrl-v.

A much better approach than all this quality control nonsense is to have inherently safe reactors, tolerant of faults in equipment, even tolerant of common mode failures. This allows standard industrial quality control to be used in stead of unachievable nuclear grade quality control.

You are absolutely correct on certificates.
They dont gtee quality. They gtee lack of competition and over-priced components.
They breed dependence
on the part of the buyer and complacency on the part of the vendor.
They slow down technical progress and improvements to a crawl.
And they relieve the buyer of real inspection and test responsibilities.
After all he's got a certificate.

Bid everybody; trust nobody.

But warranties are quite different.
They dont prevent anybody from bidding
but they do make sure the bidder is prepared to back up his product.

I'm guessing your right, and the article means certificates
rather than warranties, but if they really were forging warranties
they should be hung,

Jack

Reliable and safely maintained are 2 different things aren't they? SK reactors have one of the highest capacity factor in the world...so surely they are the very reliable on average, right?
