Plant testing and test controls

Question 1

according to OP1.ID4

what qualifies a test or evolution to be a IPTE

(infrequently performed test or evolution)?

Answer 1

Activity performed less freqently than quarterly and if not properly conducted properly may result in high probability:

• significantly reduce safety margins
• introduce plant transients
• introduce plant trips

Question 2

For tests required by Tech Specs is there a grace period that allows due date to be extended?

If so by how much?

Answer 2

yes, 25% grace period if plant conditions prevent test performance before due date

Question 3

according to AD13.DC2 (gauge oscillations during performance of tests on safety related pumps) what is the maximum oscillation allowed before action must be taken to reduce?

Answer 3

2% of gauge span

Question 4

what is criteria for suspension of a test?

Answer 4

• jeopardizes reactor safety
• jeopardizes personnel safety
• could damage equipment
• could violate license requirement
