Hello fellow Wikipedians,

I have just modified 4 external links on Petten nuclear reactor. Please take a moment to review my edit. If you have any questions, or need the bot to ignore the links, or the page altogether, please visit this simple FaQ for additional information. I made the following changes:

When you have finished reviewing my changes, you may follow the instructions on the template below to fix any issues with the URLs.

On the contents of "Safety issues"

Latest comment: 5 years ago1 comment1 person in discussion

I have some concerns about the contents of the section "safety issues", especially the quotes from Mr. Saris. After reading through sources [18] and [21] it has become clear that at least the second quote in the wiki, as well as numerous other allegations by Mr. Saris are not in line with official reports and investigations by panels of experts. Source 18 directly rejects the quote it's supposed to be supporting, stating (roughly translated)^[1]: "The automatic activation of the emergency power plant had failed due to a fault in the control- and signalvoltage. This voltage is supplied through a AC-DC converter supplying 110V with battery backup. In case of total power loss to the complex, power to this AC-DC converter is also cut, and the battery is supposed to take over. This battery failed, and as a result none of the three backup generators started. The reactor of the HFR had, as per design, shut down automatically after power was cut and the facility switched to emergency power from the Emergency Power plant (Dutch: Noodvoeding installatie) and the Supply Without Interruption (Dutch: Voorziening Zonder Onderbreking) with which, among other things, the electric post-shutdown cooling pump (Dutch: nakoelpomp)could be run for half an hour. Next to this the emergency diesel cooling pump was completely available. After about 4 minutes grid power returned and within 10 minutes the reactor was started again."

Source [21], the NRC article, points out that most claims Saris made in 2016 were either not in line with expert opinions or factually untrue, like his claim that the reactor was no longer used for research (at the time it was in use for research into molten salt reactors among other things) and that the isotopes made there could be made more easily and cheaper in cyclotrons.

In conclusion I doubt Mr. Saris should be quoted in the article at all, but I do think it should be mentioned that numerous safety issues have arisen over the years, most recent incidents being of INES level 0, but also some incidents of INES level 1 and 2 in 2013 ^[2]. Next to this NRG, the owner of the facility, was placed under strengthened surveillance by the ANVS, the dutch government agency for nuclear safety, in 2013 ^[3], but that same agency published in 2016 that it had found that the safety situation had improved considerably ^[4].
