Load and Environmental Qualification Sample Clauses

Load and Environmental Qualification. ‌ Two different plant conditions are expressed: • Normal conditions: This corresponds to the normal operation of the plant and for which all systems are requested to operate properly. These conditions are encountered during the whole life of the plant (14 years of nuclear operation and 10 years of commissioning operation), • Accident conditions: This corresponds to a highly degraded operation of the plant due to unlikely failures or highly hypothetical failure. Safety classified VVPSS instruments are requested to operate properly during accident conditions (with accepted partial degradation of performance). The accident conditions are encountered only once during the whole life of the plant. The negative effect of ageing on component shall be taken into account; that means the safety classified equipment shall operate properly throughout the whole life of the plant.
