BWR Reactor Internals Management
BWR Reactor Pressure Vessel Internals began cracking at many units early in plant life. The industry responded with an industry-wide BWR Vessel and Internals Project (BWRVIP) in 1994, which addressed all BWR internals and helped avoid shutdowns by instituting and executing plans to resolve related issues. Structural Integrity Associates, Inc. (SI) has specialized expertise in managing BWR vessel internals, and can support utilities in implementing various aspects of BWRVIP's Inspection and Evaluation Guidelines, including proactive analysis, outage preparation, and repair/replacement reviews. As cracking continues and structural margins decrease, more sophisticated analysis methods may become necessary to reduce conservatism and to gain margins, and SI has developed advanced linear-elastic and elastic-plastic fracture mechanics methods to further evaluate internals degradation.For information, please contact This e-mail address is being protected from spambots.
