AREVA Adhesive Technology. A method to mitigate and/or prevent leaks in pools with stainless steel liners Georg Kramer AREVA GmbH IBOC-G

Repair methods with conventional welding technique are not promising as a preventative measure mostly due to cost and time issues. With the provided repair method, the AREVA adhesive technology, it is possible to stop existing leaks and work as a prophylactic measure against future penetration from the concrete side of the pool. This technique can cover the failure mechanisms from weld failures over corrosion to mechanical stresses. Another advantage of the adhesive technology is the possibility of using remote-controlled underwater repair methods which are particularly beneficial in the repair of leaks in spent fuel pools. Extensive laboratory testing and longstanding successful experience in nuclear power plants have proved the suitability of the adhesive technology as active and proactive methods to minimize leakages in pools.
