ASME ASME Nuclear Components NQA-1 2

Question 1

Under ASME NQA-1, what must a 'Corrective Action' program accomplish?

Accepted Answer

Identify, control, and correct conditions adverse to quality, with significant conditions requiring root cause analysis

Answer

The NQA-1 corrective action program requires identification and correction of conditions adverse to quality; significant conditions require root cause analysis and preventive action documentation.

Question 2

In ASME Section III nuclear piping analysis, what are 'Level D' service limits?

Accepted Answer

Faulted conditions — the most severe design basis events

Answer

Level D service limits (faulted conditions) represent the most severe loading events (e.g., safe shutdown earthquake combined with LOCA) that the component must sustain without loss of function.

Question 3

Which ASME NQA-1 requirement addresses the procurement of nuclear-grade materials and components from suppliers?

Accepted Answer

Requirement 7 — Control of Purchased Items and Services

Answer

NQA-1 Requirement 7 establishes the requirements for qualifying suppliers and controlling the procurement of items and services to ensure nuclear-grade quality.

Question 4

Under ASME Section XI, IWB applies to which class of nuclear components?

Accepted Answer

Class 1 pressure-retaining components

Answer

IWB of ASME Section XI provides inspection requirements for Class 1 pressure-retaining components (reactor coolant system boundary).

Question 5

What is the purpose of a 'Source Verification' activity in nuclear procurement under NQA-1?

Accepted Answer

To verify that items or services being procured conform to specified requirements at the supplier's facility before shipment

Answer

Source verification (source inspection) involves sending a qualified inspector to the supplier's facility to verify conformance to procurement requirements before the item is shipped.
