SUMMARY
- Operator licensing examinations w'ere conducted at FitzPatrick during the period of February 12-14, 1985. Three Reactor Operator candidates, four
. Senior Operator candidates, and three Instructor Certification candidates were admin.istered written and oral examinations. One Reactor Operator candidate and
" ore Instructor Certification candidate failed both the written and oral examin-ations. One Reactor Operator candidate and one Senior Operator candidate failed the. written examination only.' During the oral examinations, all candi-dates . were noted to be very knowledgeacle in the use of Technical Specifica-tions'-and the Emergency Plan. Weaknesses were noted in the candidate's -
' abilities to use piping and instrument drawings as well as basic logic dia-
. grams. During gracing of the written examinations, the Rector Operator candi-dates were noted to be weak in the area of Plant Design / Instrument Controls.
No generic weaknesses were noted during the grading of the Senior Reactor Operator written examinations.

With the plant operating at 90% power, extraction steam to the highest pressure feedwater heater is removed. An enginect. observing that turbine load increased by 15 MWe after the extraction steam r e ni o v a l ,
concludes that this action has improved the plant's thermodynamic efficiency (N01 heat rate). Do you agi ec with this conclusion? Caplain your answer fully. (2.0)

a) With no further pulling of rods, can the operator maint'iTn this Reactor period for Fminutes?
Explain your answer. (1.5) b) By pulling rods can the operator maintain the 60 second period for 30 minutes from the 1 watt power level?
Explain your answer. (1.5)

A Reactor Scram will occur on low level. During the time period just prior to the scram, is the Reactor Power expected to increase or decrease? Give two reasons for your answer. (2.5)
Answer:
Decrease (0.5)

ANSWER 1 07' (3.00)
DECREASE.CO.53 REASONS!1( 2 of 3 required at 1.25 each)
- 1. Immediately the loss of foodwater flow causes a decrease in moderator subcooling which introduces negative dk/k into the core..
- 2. When feedwater flow drops below 20%, the recire. pumps will auto runback to 20%. The decrease in core flow causes an inercase in voiding which also adds negativo dk/k into core.
- 3. Decreasing level in the downcomer will reduce the available head for core circulation and will result in decreased core flowe.and thus reactor power will decresso.

. l Question and Answers to James A. Fitzpatrick SR0 Exam - 2/12/85 5.0 Theory of Nuclear Power Plant Operation, Fluids and Thermodynamics (25.0) 5.1 Assume Fitzpatrick is at 100% power and flow. Condenser vacuum decreases thus causing the hotwell temperature to increase to the saturation temperature of the new vacuum. This in turn causes the temperature of the feed water to increase.
a) Would Reactor power increase or decrease? Explai n. (1.0) b) Would Core Flow increase or decrease? Explain. (1.0)
Answer:
a). Decrease (0.25) Increased temperature of feedwater would increase negative reactivity insertion of moderator coefficient (0.75).
b) Increase (0.25) Core Flow would increase due to reduced two phase pressure drop across core. (0.75).

.4-5.2 'Will the recirculation pumps have more NPSH at 4% or 100% power? Explain your answer fully. (2.0)
Answer:
More NPSH at 100% power. (0.5)
At 4% you are at operating pressure but low feedwater flow the temperature at the recirculation pump inlet is nearer to saturation than at 100% power where there is a higher percentage of feedwater in the downcomer causing the temperature at the inlet of the recirculation pumps to be lower. (1.5)

5.4 While Fitzpatrick is operating at 90% power, extraction steam l to the highest pressure feedwater heater is removed. An i engineer observed that the turbine load increased by 20 MW l electric and concluded that this action has improved (increased) the plant's thermodynamic efficiency (not heat rate).
Is this conclusion correct? Explain your answer fully.
(Include what caused electrical output to increase). (2.5)
Answer:
No (0.5) thermo efficiency is a comparison of Energy In to Energy Out (0.5). The _ increase in output results from no steam being diverted to the high pressure feedwater heater (0.5). Because the feedwater is now cooler, more energy from the reactor is required to bring the water up to saturation temperature (0.5) thus thermo efficiency is down (0.5).

8.5 Fitzpatrick is operating at 90% power. You are to be the Shif t l Supervisor From 12:00 midnight - 8:00 a.m. shift. During shift change you are informed that during your shift the pressure suppression - Reactor building suppression chamber vacuum breaker instrumentation surveillence is to be performed. You are further told it has been five (5) menths since this surveillence test was last performed. The instrument technicians performing the surveillance tests inform you that one of the vacuum breaker's pressure switch is in-operable and the vacuum breaker pressure switch has a as-found setpoint of 1.0 psid. They also inform you that the in op pressure switen must be replaced and it will take two (2) weeks to get a new switch.
