We are pleased to announce the first HI-STORMs have been loaded and placed on the ISFSI at ANAV’s Ascó Nuclear Power Plant in Tarragona, Spain. This two (2) HI-STORM campaign came to a successful close in May bringing the total number of HI-STORM systems loaded in Spain to fourteen (14). Ascó is a twin unit Westinghouse PWR, each unit is rated at approximately 1000 MW(e). The plant site is approximately a 2-hour drive from Barcelona in the country’s northeast region.


ENRESA awarded Holtec a contract in 2008 following a competitive bidding process under which Holtec has completed the first phase, including licensing the HI-STORM 100 and HI-STAR 100 Systems in Spain to accommodate the Ascó spent nuclear fuel, damaged fuel, and non-fuel hardware. The supply of ten (10) HI-STORM 100 systems and the compliment of ancillary equipment not presently owned by ENRESA was completed in March 2013. ENRESA and ANAV are both pleased with Holtec’s support throughout this project and during the loading campaign.

“This is a major milestone in the Ascó Project and I would like to congratulate ENRESA, ANAV, and Holtec’s project teams for this success.” said Holtec’s Senior Vice President of International Projects, Dr. Bill Woodward.

“It has been a long process and we feel proud of the successful culmination of this initial loading campaign” said Jordi Estrampes, ANAV’s dry cask team leader and Reactor Engineering and Nuclear Safeguards Supervisor at the Ascó Nuclear Power Plant.

“I would like to thank all the multidisciplinary project team for their commitment and its efficacious accomplishment” added José A. Gago, ANAV’s General Manager & CEO.

Dr. Pablo Zuloaga, Engineering Director of ENRESA added, “It is the hard work and dedication of all team members that has made this project a success.”

The ISFSI can hold up to 32 HI-STORM overpacks, each storing an MPC-32 containing 32 PWR fuel assemblies. It will cover the dry storage needs for the two Ascó units until the Spanish centralized interim spent fuel storage facility (ATC) is commissioned in 2017.

Holtec has three ongoing projects in Spain, Ascó, Jose Cabrera, and Trillo. Jose Cabrera, which has already completed successful loading of their HI-STORM systems, will be utilizing Holtec’s HI-SAFE technology later this year to store Greater Than Class C waste (GTCC).
