Shield Source Inc.

Tritium light source processing facility

Shield Source Inc. operated a gaseous tritium light source processing facility from 1986 to 2013. The facility was permanently shutdown in March 2014. The facility received tritium gas in sealed containers from a CNSC-licensed facility and then inserted the gas into glass tubes to create luminescent exit and aircraft signs.

  • March 28, 2014: The Canadian Nuclear Safety Commission (CNSC) announced its decision to issue a Licence to Abandon to Shield Source Inc. (SSI) for its gaseous tritium light source processing facility located in Peterborough, Ontario. As of April 1, 2014, SSI is no longer subject to the CNSC’s regulatory requirements.

    In March 2013, SSI announced it would close its facility. Clean-up and decontamination work was carried out by qualified staff under the regulatory oversight of CNSC inspectors. CNSC independent sampling of air, soil and water concluded that the building is clear and there is no health risk to the community or the environment. The site can now be used for other industrial purposes.

  • January 9, 2014: Following a hearing, the CNSC announces its decision to extend the Shield Source Inc. (SSI) operating licence. The licence is valid until March 31, 2014.

    In March 2013, SSI notified the CNSC of its intention to cease operations in 2013, and to apply for the Commission's approval to release the facility of regulatory control once it has been cleaned up to its intended future use.

    The three-month extension will allow SSI time to complete the clean-up and decontamination activities, and to provide their final report to CNSC staff.

    There have been no changes in the licence conditions, except for the expiry date.
