Darlington Nuclear Station water release update - No. 3

Normal levels of tritium continue in evening samples

TORONTO , Dec. 22 /CNW/ - Water sampling at local water treatment facilities, this evening, continue to indicate normal levels of tritium following an inadvertent release of water containing hydrazine and extremely low amounts of tritium at the Darlington Nuclear Station yesterday.

Last evening, Darlington Nuclear staff, taking a conservative approach, consistent with OPG's commitment to public safety as its first priority, began an extensive notification process with health and public works officials following the release.

Today, after thorough monitoring, sampling, testing and diagnostics, it has been verified the amount of tritium released to the environment was in fact extremely low, far less than 1 per cent of the regulatory limit and consistent with normal operational activities.

Regular testing at local water treatment facilities will continue until further notice and OPG will continue to post updates at OPG.com.
