Authorised Prohibited Authorised Prohibited Authorised Prohibited Authorised Presence of solid aluminium end pieces Authorised Prohibited Authorised Height of the active part of the plates (mm) 1,030 Protrusion of the active part outside of the basket (mm) 0 (1) Where:
b, nominal width of the plate (mm),
t, nominal thickness of the plate (mm),
Ueq, the equivalent density of the plate (fissile core and cladding) (kg/mm3),
Re, the yield strength of the fuel cladding (MPa) considered at the maximum temperature under normal conditions of transport depending on the power actually transported, as given in table 0A-9.10 in Chapter 0A-9 of the Package Design Safety Report DOS 00032593-013 Rev. 5, depending on the grade of cladding used.
(2) The loading plan must comply with figure OA-9.4 of Chapter 0A-9 of the Package Design Safety Report ref. DOS-06-00032593-013 Rev. 5.
(3) The loading plan must comply with figure OA-9.6 of Chapter 0A-9 of the Package Design Safety Report ref. DOS-06-00032593-013 Rev. 5.
(4) The loading plan must comply with figure OA-9.3 of Chapter 0A-9 of the Package Design Safety Report ref. DOS-06-00032593-013 Rev. 5.
(5) V/235U: ratio calculated for the flat plates:
where V is the product of the nominal thickness of a plate multiplied by the nominal fissile height and by the nominal fissile width,
where 235U is the total mass of 235U of the element divided by the number of plates.
(6) Elements which satisfy the characteristics of one of the columns in this table, and are "authorised", as indicated, can be mixed with other "authorised" elements in this table.
