Trillo

Trillo

Reactor: PWR

Location: Guadalajara, on the banks of the river Tajo

1988 Construction started on Unit 1 and commissioned for commercial use

1994         The licensee initiated a far-reaching design review programme known as the
                 Operating Experience and Systems Analysis (OESA), with technical support from the
                 main supplier, SIEMENS-KWU, and other engineering companies

2004         Within the framework of the programme to address severe accidents (with core
                 damage), the Council reported favourably on the licensee’s proposal not to carry out
                 the design modification of the containment filtered venting system that had been
                 implemented at various European nuclear power plants, this modification not having
                 been performed at the other Spanish plants or in the USA

2008         After evaluating the cost-benefit analysis carried out by Trillo NPP, the CSN required
                 the licensee to submit the project for the installation of the design modification for a
                 “bleed and feed” system aimed at improving the plant safety levels within nine months

2009 Trillo has submitted to CSN a project for the installation of a “bleed and feed” system
that is currently under evaluation
