The Nuclear Regulatory Commission has established the Light-Water-Reactor Pressure Vessel (LWR-PV) Surveillance Dosimetry Improvement Program in order to improve and standardize the procedures for dosimetry, damage correlation, and associated reactor analysis used for predicting the integrated effect of neutron exposure on LWR-PVs. This multilaboratory international program is developing and validating a series of 17 standard procedures for neutron surveillance dosimetry and embrittlement evaluation and is establishing a series of benchmark experiments for neutron physics calculations, dosimetry measurements, and embrittlement predictons. Recommendations already developed include (1) the necessity for benchmark referencing of reactor physics calculations using the Pool Critical Assembly test data from Oak Ridge National Laboratory, (2) the use of dpa (displacements per atom) as an improved exposure criterion replacing ''fluence > 1 Mc V'', and (3) the necessity for dosimetry measurement certification.
