Trawsfynydd

Trawsfynydd Power Station lies within the boundaries of a National Park of considerable beauty and is located on the northern bank of Llyn Trawsfynydd.

Following the decomissioning of the plant, the existing building structure is to be reduced in height and encased in a new 'Safestore' envelope. The objective is to reduce and in some cases eliminate the buildings impact within the National Park.

The Safestore structure is to provide an aesthetically acceptable, cost effective means of long term, secure storage for specific radioactive materials and structures. As well as minimising the visual impact of the site the structure is based on the following criteria:

The design life shall be 135 years. During the majority of this period it is proposed that the site will be unmanned. The structures shall be intruder resistant with a 9m wall also giving an improved visual balance between the lower and upper levels of the external elevations.

The landscape within the site boundary will reflect the character of the natural surrounding landscape so the there are no visible boundaries and the landscape flows naturally through the site.
