AFFIDAVIT OF ANTHONY F. SILAKOSKI IN RESPONSE TO LICENSING BOARD'S SUA SPONTE QUESTIONS County of Lake )

State of Ohio )

Anthony F. Silakoski, being duly sworn, deposes and says as follows:

1. I, Anthony F. Silakoski, Training Unit Supervisor, Perry Pl At Department, The Cleveland Electric' Illuminating Company. My business address is 10 Center Road, Perry, Ohio, 44081. A summary of my professional qualifications and exper-ience is attached hereto as Exhibit.A. In my position, I over-see the design, preparation and presentation of all. simulator

. training and on-site training for operstor license applicants.

I have personal knowledge of the matters set forth herein and believe them to be true and correct.

2. The'first question posed by the Licensing Board states:

To what extenf nes the simulator training for operators ..he Perry reactors include training in dif zentiating different kinds of instrument failures from transient or accident conditions.

3. Perry operators receive extensive training on the Perry simulator. Included in this training are a variety of situations involving instrument failures.

4. Instruments generally have more than one display channel, thereby providing redundant displays of critical parameters.

- Power is supplied to each of these channels from separate power sources (buses). A routine part of simulator training is the simulated failure of each bus, and combinations of buses, culminating in a station blackout. Simulated loss of power to a bus will cause a single instrumentation channel to " fail".

Operators are trained on these scenarios to determine, by

. evaluating alternate indications, which channel has failed.

Operators are trained to compare readings on one type or range of instrumentation with readings on redundant or related instru-ment types and channels to ascertain whether readings are aberrant.

5. Another type of simulator training involving instrument failure is the simulated failure of the process computer. The computer system displays various plant parameters, including reactor power, reactor water level, and reactor system pressure, l

on the three CRT displays and two digital display windows. The simulated computer failure freezes the displayed parameters while

" actual" plant parameters continue to change in other parts of the simulator. This scenerio is routinely used on the simulator to train operators to frequently compare and contrast key dis-played parameters with alternate channels and related instrumen-tation in order to detect instrument abnormalities or failures.

6. A third type of simulated instrument failure used on the Perry simulator is generated by a simulated small break LOCA in the dry well which causes erroneous pressure readings in the Control Rod Drive Hydraulic System.

7. The second question posed by the Licensing Board states:

To the extent that some kinds of instrument failures are not simulated during training, please explain whether the omission is detri-mental to the safe operations of the reactors.

8. In addition to the specific examples of simulator . training for instrument failures described in paragraphs 3-6, many other aspects of the Perry operator training program equip the Perry operators to safely deal with potential instrument failures.

9. In general, operators are trained to compare and contrast the indications of all related instrument types and ranges. This will assure that aberrant instrument behavior-is quickly identified.

10. Where instrument failures create ambiguity as to the existing plant conditions or equipment status, operators are trained, both in classroom and on the simulator, to respond to the worst case parameter. This is reinforced by the Plant Emergency Instructions which are symptom-oriented, rather than event-oriented, thus minimizing the risk of improper diagnosis leading to improper actions.

11. Detailed classroom instruction in Abnormal Events Analysis of all senior reactor operators includes the most likely plant responses and indications which would be observed.

This provides a sound basis for recognizing instrument failures during these conditions. Similarly, operator exposure to a mul-titude of transients on the Perry simulator provides a familiarity with expected instrument responses, allowing the operator to identify failed instruments should they occur.
