A public Canadian Nuclear Safety Commission (SNSC) meeting is scheduled for Friday, September 3rd to talk about the recent discovery of elevated hydrogen equivalent concentrations and the responses by nuclear power plant licensees and CNSC staff.

The meeting is being held by the External Advisory Committee on pressure tubes.

You may recall Bruce Power ran into some issues earlier in July with the condition of pressure tubes in two units which are not operating at this time.

A Commission report says the Bruce Power pressure tubes in Units 3 and 6 had higher measurements of hydrogen equivalent (Heq) than predicted which contravened the company’s operating licence conditions.

A Commission report says the Bruce Power pressure tubes in Units 3 and 6 had higher measurements of hydrogen equivalent (Heq) than predicted which contravened the company’s operating licence conditions.

The reactors with the higher hydrogen content in pressure tubes are shut down for refurbishment and maintenance outages and do not pose a safety concern to the public or environment.

Hydrogen content is not a concern when reactors are shut down or have reached operating temperature.

At the time, the CNSC said in its release, “Since hydrogen content can only be measured while the reactors are shut down, CNSC staff have directed Bruce Power to assess the fitness for service of the other operating reactors and issued formal notices to all nuclear power plant licensees in Canada requesting further analysis on the continued safe operation of pressure tubes.”
