| Summary: | Results of the implementation of programs on the
evaluation of service life of reactor pressure vessels
of NPP are considered with the account of neutron
embrittlement. Data on strength of
WWER-440 reactor pressure vessels with a high
and moderate content of detrimental impurities
(copper and phosphor) have been analyzed. For
the welds of WWER-1000 reactor, drawbacks in
the manufacture, dosimetry, and test procedures of
surveillance specimens are shown. To ensure safe
operations of reactor pressure vessels, new projects
have been undertaken, focusing on the effect
of neutron embrittlement of steel on the integrity
of structures and advanced experimental methods
of studying material strength. |
