Where a small opening lies beyond the distance w p defined in 9.7.3, no reinforcement check is necessary. Where itlies within this distance, the reinforcement shall be in accordance with equation (9.5-7) or (9.5-11) as appropriate.However the distance w between small opening and shell discontinuity shall respect the minimum value w min as
required in 9.7.1.
9.5.2.3 General requirements for reinforcement
9.5.2.3.1 Reinforcing pads
For cases where a reinforcing pad contributes to the reinforcement (see Figures 9.4-3, 9.4-4, 9.4-10):
reinforcing plates shall be fitted in close contact with the shell.
the width of a reinforcing plate l' p to be considered as contributing to reinforcement is given by
);min('

the value of e p used for the calculation of Af p shall not exceed the following
);min( ,, sc pa p eee (9.5-20)
furthermore the analysis thickness of the reinforcing pad shall meet the following condition
ea,p 1.5 ea,s (9.5-21)
ea,p and l p are dimensions of reinforcing pads used in equations for openings that may be reinforced also byreinforcing pads; if reinforcing pad is not present then the values ea,p and l p shall be put equal to zero. If thereinforcing pad is contributing to reinforcement then, for all cases:
p p p el Af ' (9.5-22)
9.5.2.3.2 Joint coefficient
9.5.2.3.2.1 Opening intersecting with a shell governing weld
If an opening intersects with a shell governing weld (see definition in 5.6), the value f s in equation (9.5-7,11,13 and16) for the shell material shall be replaced by f s·z, where z is the joint coefficient of the shell.
9.5.2.3.2.2 Nozzle with a longitudinal weld
If a nozzle has a longitudinal weld having a weld joint factor z, the value f b for the nozzle material shall be
replaced by f b z except for openings in cylindrical or conical shells if the angle as defined in subclause 9.3.2 isgreater than 45°.
9.5.2.3.2.3 Reinforcing pad with a weld
If a reinforcing pad has a weld having a weld joint factor z, the value f p for the pad material shall be replaced by f p z except for openings in cylindrical or conical shells if the angle between the pad weld and the shell generatrixis greater than 45°.
9.5.2.3.3 Fillet weld areas for compensation
For all cases:
Af w is the area of any welds connecting together the different components (shell to nozzle, shell to reinforcingring or reinforcing plate) which is located within length l’ s on the shell (see 9.5.2.4.2) and lengths l’ b and l’ bi on the nozzle (see 9.5.2.4.4.1). Areas of welds already included in other areas, e.g. Af s, Af r , Af p or Af b, shall be

B.9.4 Creep Rupture (CR)
B.9.4.1 Principle
For each creep load case, the design value of an action, or of a combination of actions, shall be carried by thedesign model with
linear-elastic ideal-plastic constitutive law,
von Mises' yield condition (maximum distortion energy hypothesis) and associated flow rule
material strength parameter RM and a partial safety factor R as specified in Tables B.9-2 and B.9-3.
proportional increase of all actions and a stress-free initial state
with the maximum absolute value of the principal structural strains being less than 5 %.
With the exception of cases where deformation has a weakening effect, see B.7.1, first-order-theory shall be used;where deformation has a weakening effect, geometrical non-linear effects shall be taken into account.
B.9.4.2 Application rule: Lower bound limit approach
If it can be shown that any lower bound limit value of the action or combination of actions, determined with thedesign model specified in the principle, is reached without violation of the strain limit, the principle is fulfilled, if thedesign value of the action or combination of actions does not exceed that lower bound limit value.
B.9.4.3 Design Checks
a) Design checks are required for normal operating load cases only
b) Partial safety factors for actions shall be as given in Table B.9-1

It may be necessary to include also effects caused by constrained temperature induced displacements in a CR-DC, e.g. when part-models are used and displacements in one model are imposed on the other model.

All permanent actions shall be included in each load case.
Each pressure action shall be combined with the most unfavourable variable action.

B.9.5.4.2 Action cycles with negligible creep
Action cycles, which interrupt long creep periods, are considered to be of negligible creep, if the maximum duration
of calculation temperatures in the creep range is less than 100 h.
B.9.5.4.3 Action cycles without plastification
Action cycles, which interrupt long creep periods, are considered to be without plastification, if the maximum vonMises' equivalent stress of the response of the model, described below, to the cyclic actions and with initialconditions, described below, does not exceed the short-term design material strength parameter, described below:
a) The constitutive law of the model shall be linear-elastic with material parameters for a temperature given inB.7.5.2.
b) The initial stress distribution shall be the one obtained like in the determination of the limit action B.9.5.3.3.3 fora reference time, required for the determination of the material strength parameters in B.9.5.3.3.2 given by the
total creep period.
c) The short-term design material strength parameter, with which the maximum equivalent stress is compared,shall be the minimum specified values of
cp0,2/T R for ferritic steels,
cp1,0/T R for austenitic steels,
where cT is the respective temperature at each point and each time.
B.9.5.5 Design checks
Actions, combination rules, reference temperature and reference time for creep periods, shall be as for the CR-DC,in B.9.4.3, but all partial safety factors for actions shall be equal to 1,0.
B.9.6 Creep and cyclic fatigue (CFI)
For each point of the structure, the sum of the design value of the creep damage indicator, see B.9.5.3, and thedesign value of the fatigue damage indicator (for cyclic actions), see B.8.5, shall not exceed unity.

5 limits of local primary membrane stress region
NOTE This figure shows the case of an opening with nozzle in a cylindrical shell. It also applies to the case of an openingwith nozzle in a spherical, conical or toroidal shell or in the central region of a dished end (R m is the circumferential mean
curvature radius). It applies as well to the case of an opening without nozzle (for this case ea,n 0). It does not apply to an
opening in a flat end or a flat wall; in such cases, see footnote11)
to Table C-2.
When the level of stress acting in the vicinity of the opening is such that a local primary membrane stress regionoccurs, the extent of this region, measured taking account of both sides of the nozzle-shell discontinuity, shall
satisfy the condition:

(C.5-2)
Possible thickness transitions which may occur between a reinforced part and an unreinforced part of the nozzleand/or of the shell do not usually involve local primary membrane stress regions.
Where, for particular geometrical or loading arrangements, such regions occur in the vicinity of these transitions,the conditions in C.7.2 relating to the spacing between adjacent regions of local primary membrane stresses shallbe met, particularly as regards the spacing from the adjacent local primary membrane region at nozzle base.
