British company NRS has officially transferred responsibility for the reactor building territory at Traufaynydd Nuclear Power Station to contracting organization Costain. This event marks the beginning of a new phase in one of the largest nuclear facility decommissioning projects. The handover of the zone opens the possibility to proceed with the next phase of work — reducing the height of the station's reactor buildings. This phase is part of a long-term dismantling program aimed at the safe and phased closure of the facility following the completion of its operation. The project to reduce the height of reactor structures is considered technically complex and requires careful coordination between contractors and regulatory authorities. The transfer of responsibility to Costain will allow the company to begin planning and executing specific engineering work at the site. Industry representatives note that the successful completion of this phase will be an important step in the overall decommissioning process of the station, and could also serve as an example for similar projects at other nuclear facilities in the United Kingdom.
