Neutron physics calculation for VVER-1000 control rod lifetime determination
19th Symposium of AER on VVER Reactor Physics and Reactor Safety (2009, Varna, Bulgaria)
Core Operation, experiments and code validation
Absorber element (AE) with compound absorber has been operating in WWER-1000 power units since 1995. AE design meets operating organizations requirements for reliability, service life (to 10 years) and safety functions. Extension of AE service life up to 20 ? 30 years by the complex of calculation and experimental work is an important problem of WWER new designs development.
