Standards

aThe

preferred design code for safety-class pressure retaining components is the ASME Code.

bFiberglass-reinforced plastic tanks may be used in accordance with appropriate articles of Section X of the ASME

Boiler and Pressure Vessel Code for applications at ambient temperature.

cManufacturers' standard for the intended service. Hydro or pneumatic pressure testing should be 1.5 times the

design pressure.

b. Loads

The following are typical loads to consider in the structural design process. The example

given is for an in-vessel component; for ex-vessel components, loads due to plasma disruptions,

for example, may not be a design factor. This list is provided as a starting point for the delin-

eation of loads for specific SSCs and may be incomplete for a particular design. The structural

designer must consider all normal and off-normal events identified in the safety analysis process

in defining load combinations for particular safety-class SSCs.

The SSC under consideration should be designed to withstand the static load, pressure

load, thermal load, electromagnetic loads (normal operating and fault), disruption/vertical dis-

placement event (VDE) loads, interaction loads from adjacent systems, and transient loads due

to normal operations and off-normal events, including design-basis events.

1. Static loads--The static load should include the weight of the equipment identified as

constituting the system (or component), any supported hardware, and process media

such as liquid inventory.
