A method for minimization of cladding failure parameter accumulation probability in VVER fuel elements
It has been proved, that under normal operating conditions the following methods of VVER fuel cladding durability control can be considered as main ones: control of fuel element (FE) construction and fuel physical properties, e.g. making fuel pellets of the most strained axial segment with center...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | It has been proved, that under normal operating conditions the following methods of VVER fuel cladding
durability control can be considered as main ones: control of fuel element (FE) construction and fuel physical
properties, e.g. making fuel pellets of the most strained axial segment with center holes – M(1); control of the
regulating group disposition – M(2); control of the balance of VVER loading regimes – M(3); control of the coolant
temperature regime – M(4); control of the FA rearrangement algorithm – M(5). Based on М(i), i = [1,…,5], a
method for minimization of cladding failure parameter accumulation probability in VVER fuel elements by means
of control of FE properties at the reactor design and operation stages, lowering the probability of FE cladding failure
and increasing the uniformity of burnup, has been developed. |
