Aging light water reactor pressure vessels (LWR-PV) are accumulating significant neutron fluence exposures, with consequent changes in their steel fracture toughness and embrittlement characteristics. Recognizing that accurate and validated measurement and data analysis procedures are needed to periodically evaluate the metallurgical condition of these reactor vessels, the US Nuclear Regulatory Commission (NRC) has established the LWR-PV Surveillance Dosimetry Improvement Program. The primary concern of this program is to improve, standardize, and maintain dosimetry, damage correlation, and the associated reactor analysis procedures used for predicting the integrated effect of neutron exposure to LWR pressure vessels and suport structures.
