✍️ Sample NANTEL Questions & Answers
1. Which best defines 'task saturation' as a human performance concern in nuclear plants?
Task saturation occurs when the number and complexity of simultaneous demands exceed a worker's cognitive capacity, dramatically increasing error probability.
2. Which of the following is the best example of a latent organizational weakness that could lead to a human performance error?
A confusing and outdated procedure is a latent weakness. It is a flaw embedded in the organization's processes that lies dormant until a person interacts with it, creating an error-likely situation. The other options describe active errors, which are the immediate slips, lapses, or mistakes made by an individual.
3. What does elevated specific activity in reactor coolant most likely indicate to a plant chemist?
High specific activity in reactor coolant indicates fission products may be leaking through defective fuel cladding into the coolant, which is monitored as a key fuel integrity indicator under 10 CFR 50 Appendix A.
4. Which NANTeL training category covers the skills needed to safely enter and work in spaces with limited ventilation, potential oxygen deficiency, or toxic atmosphere hazards?
Confined Space Entry training addresses OSHA requirements and nuclear site procedures for identifying permit-required confined spaces and safely entering them.
5. Which fire suppression system agent is commonly used in nuclear plant cable spreading rooms due to its ability to suppress fire without damaging sensitive equipment?
CO2 and clean agents like FM-200 suppress fires without leaving residue that could damage electronics or cables.
6. When an operator discovers a discrepancy between a procedure step and actual plant conditions, the correct immediate response is to:
Discrepancies between procedures and plant conditions must be resolved with supervisory guidance before continuing.
