IC67 - Pre-Instructional Survey 1. What does the term code refer to in the installation of power plant piping? a. National welders code b. Fire protection code c. ASME Boiler and Pressure Vessel Code Section III 2. Nuclear Safety-Related systems are essential to? a. Protect plant personnel from injury b. Prevention or mitigation of significant release of radioactive material to the environment c. Productive supply of electrical power 3. What does the term pressure boundary integrity mean? a. The capability to retain the process fluid b. Maintains system pressure during operation c. Controls process pressure within specific limits 4. In the context of this standard what does qualified mean? a. Able to install transducers for the plant staff b. Demonstrated to be acceptable for the design requirements c. Successful class completion 5. Where the only code function for a device is mounting, what evaluations are necessary? a. Instrument and supports will not fall and damage other equipment b. Tubing and supports will not fall and damage other equipment 6. How are seismically qualified transducers mounted? a. In the same configuration as the qualified configuration b. Best orientation for plant location c. Around other seismically qualified transducers 7. Impingement barriers are used for: a. Preventing postulated missiles from striking instruments b. Stopping leakage c. All the above 1
8. Unless otherwise justified, auxiliary equipment shall be mounted. a. Follow the requirements of off-line transducers b. Independent of other mounts 9. Transducers shall not be installed in locations with environments that may exceed the qualified capabilities of the transducer, except. a. There is no other device b. The transmitter will probably survive to environment c. The potential adverse environment will only exist after the transmitter function is no longer required. 10. What ambient operating conditions, as a minimum must be considered? a. Temperature, pressure sun angle, radiation b. Radiation, humidity, pressure, temperature c. Radiation, electromagnetic effect, temperature 11 What pipe or tubing sizes are covered by the standard? a. 2.54 cm or less outside diameter and pipe 1.9 cm or less outside diameter b. All small pipe and tubing c. Piping smaller than 25.4 cm outside diameter 12. What is the difference between a sensing line and a sample line? 13. Primary Containment wall penetration is ASME Section III Class 2 Seismic Category 1, what is the classification of the sensing line past the containment isolation valve? a. ASME Section III Class 2 Seismic Category 1 b. ANSI B31.1 Seismic Category 1 c. No classification required 14. Why are capillary lines with diaphragm seals used? a. Long tubing runs through high temperature rooms b. Isolation of potentially highly contaminated fluids c. Easier than a tubing installation 2
15. For remote seals what is the largest effect on system performance? a. Pressure of the process b. Process fluid c. Temperature of the environment where the capillarity is routed. 16. What is an isokinetic sample? a. Sample where the kinetic energy of the particles are identical in the sample line as in the process line being sampled. b. Sample stream is representative of the process stream in particle size and composition 17. When should restriction orifices not be used? a. Where constituents of the fluid may be trapped b. Where flow would be restricted c. Where a tubing break could result in excess flow from the system 18. What is the proper tap location for pressure measurement on a gas system? a. Side b. Top c. Bottom 19. What does the term single failure proof mean in sensing line installation? a. No active or passive failure will prevent the safety function b. No passive failure will prevent the safety function c. No failure will cause the failure of more than one redundant sensing line unless the function will still be accomplished. 20. A detailed seismic analysis must be performed for each tubing installation. 21. Instrument line slope is necessary because: a. Smooth transition from process connection to instrument connection b. Prevents entrapment of liquid in gas lines c. Prevents the tubing being used as a ladder 3
22. Once the tubing is routed the installation is complete. 23. Loops in the tubing are used to make the drawing interesting. 24. It is best to use a single tap and tube installation for all redundant sensors. 25. Potential inaccuracies in water level indication during and after repid depressurization events have been identified as industry concerns and shall be considered in routing? 4
