i SPDS Operator Training Program Outline for Man-in-the-loop Validation 1.0 OBJECTIVE The objective of the training program is to ensure that operators who will participate in man-in-the-loop validation of the SPDS are thoroughly familiar with the operation of - the SPDS and interpretation of SPDS displays.

2.0

SUMMARY

OF TRAINING PROGRAM The following approach will be used for the training:

a. Each operator will receive formal," hands-on" training using the SPDS hardware and software which will be driven by simulated static and dynamic inputs.

b. The " Millstone Three Computer Systems" training manual will be used as the basis for instruction.-

c. Oral and written testing will be used to identify areas of weakness in each operator's understanding of the SPDS. Remedial training will be given to correct weaknesses identified by the testing,

d. The oral and written tests will require callup and interpretation of SPDS displays for correct answers to some of the questions.

e. A permanent record of each operator's training will be retained.

3.0 LESSON PLAN 3.1 Static Displays

a. Purpose of SPDS

b. CSF's monitored

c. Signal validation

1. Validation process

2. Quality tags

3. Failed sensors

4. Uses of unvalidated sensors

d. Computer failure indication

e. SPDS displays

1. Color coding

3.2 Dyr.amic Displays The simulation tape, scenario #4 (modified Three Mile Island) will be used to generate dynamic inputs. The following topics will be observed and discussed,

a. CSF status changes

1. Auto rollup and blinking of CSF status boxes

2. Callup of affected CSF status tree - RED alarm

a. observation of alarm path

b. observation of validated parameters

3. Callup of affected CSF status tree - YELLOW alarm

a. observation of alarm path

b. return to menu - CSF function button

b. Status tree sensor data display

1. Callup of affected CSF status tree sensor data display and of X, U and blank quality tags 2.. Observation of highest and lowest CET temperatures; red, green and yellow values

3. Observation of subcooled values and above-limit values on subcooled/superheated display

c. P-T plot

1. Callup of P-T

2. Observation of time histories

3. Exercising zoom-in/ zoom-out feature

d. Containment CSF display

1. Observation of " adverse containment" flag

2. Callup of containment sensor data display

a. observation of cause of adverse containment b, observation of other parameters 4.0 STUDENT PRACTICE The dynamic simulation will be rerun and each operator will have the opportunity to practice SPDS operation and receive answers to any questions.

.- 0 . .

_4 5.0 EXAMINATIONS 5.1 Oral Examination Static inputs to the SPDS will be established. Questions will be asked of each operator in turn while the other operators observe actions and responses. Erroneous responses will be corrected immediately.

5.2 Written Examination A written examination will be given to each operator. Some of the questions will require operation of the SPDS to determine correct answers.

6.0 REMEDIAL INSTRUCTION Written examinations will be corrected and correct responses will be presented and illustrated where erroneous answers were given. Additional

• training will be provided if needed.

7.0 TRAINING RESULTS Written examinations will be retained as training records in the SPDS project engineer's auditable files along with a copy of this training program outline.
