ASME ASME Nuclear Components NQA-1 2 — Questions and Answers
Question 1: Under ASME NQA-1, what must a 'Corrective Action' program accomplish?
- Document all quality inspections performed during fabrication
- Identify, control, and correct conditions adverse to quality, with significant conditions requiring root cause analysis (Correct answer)
- Verify that all personnel hold valid qualification certifications
- Report all deviations to the Nuclear Regulatory Commission within 24 hours
Correct answer: Identify, control, and correct conditions adverse to quality, with significant conditions requiring root cause analysis
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?
- Normal operating load conditions
- Upset (emergency) plant conditions
- Faulted conditions — the most severe design basis events (Correct answer)
- Fatigue cycling conditions
Correct answer: Faulted conditions — the most severe design basis events
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?
- Requirement 2 — Quality Assurance Program
- Requirement 7 — Control of Purchased Items and Services (Correct answer)
- Requirement 14 — Inspection
- Requirement 18 — Audits
Correct answer: Requirement 7 — Control of Purchased Items and Services
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?
- Class 1 pressure-retaining components (Correct answer)
- Class 2 pressure-retaining components
- Class 3 pressure-retaining components
- Component supports for all classes
Correct answer: Class 1 pressure-retaining components
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?
- To audit a supplier's quality program annually
- To verify that items or services being procured conform to specified requirements at the supplier's facility before shipment (Correct answer)
- To certify that a nuclear material meets ASTM chemical composition requirements
- To review the supplier's corrective action records
Correct answer: To verify that items or services being procured conform to specified requirements at the supplier's facility before shipment
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.
Question 6: Under ASME NQA-1, what document establishes the overall quality assurance program for a nuclear facility project?
- Quality Control Plan
- Quality Assurance Program Description (QAPD) (Correct answer)
- Inspection and Test Plan
- Non-Conformance Report
Correct answer: Quality Assurance Program Description (QAPD)
The Quality Assurance Program Description (QAPD) is the top-level document that describes how the organization implements each NQA-1 requirement throughout the project lifecycle.
