In other words, the nation’s top concrete and structural engineering experts say that as of today there simply isn’t enough research to know exactly how to properly repair or manage ASR or predict the future structural integrity of a nuclear plant that suffers from it.
Getting this right is critical, as other nuclear plants may be found to have the same condition and the NRC must establish a sound scientific basis for the testing and monitoring that will be necessary at Seabrook and possibly elsewhere. Tests at Seabrook show that ASR will continue into the future and will therefore continue to impact the structural integrity of Seabrook’s structures. It is critical to have sound, indisputable science determine the fate of Seabrook.
