TESTIf10!1Y OF JOHit F. BURD0Irl Q.1.
Please state your name and position with the flRC.
A.1.
fly name is John F. Burdoin.
I am employed as a Reactor Inspector, Reactor Construction Projects Branch, Region V, U.S. Nuclear Regulatory Comnission, Walnut Creek, California 94595.
Q.2.
Please describe your educational background and previous positions held.
A.2.
I have a Bachelor of Electrical Engineering Degree from the University of Minnesota.
I am registered as a Professional Engineer in California in electrical, mechanical and nuclear engineering.
I have been employed by the flRC since August 1976.. As an Engineering l
Systems Analyst, I analyze and evaluate specific features associated with the design and operating characteristics of licensed power and testing reactors in regard to the engineering features of electrical instrumentation and control systems and auxiliary and power conversion systems.
Prior to my present employment, I was employed by the Lawrence Liver-more National Laboratory at Livermore, California for a period of 18 years.

. During this period, I served in various positions in the field of electrical engineering.
Q.3.
Please describe the extent of your participation in the flRC Staff's review of the GETR for this proceeding.
A.3.
I prepared Section B of the October 27, 1980 portion of the Staff's Safety Evaluation Report entitled "GETR Electrical, Instrumentation and Control Systems" in the areas of the seismic scram system and control and instrumentation equipment important to safety.
Q.4.
Briefly summarize the results of the Staff's review and your conclusions.
A.4.
The licensee has described in detail the electrical, instrumen-tation and control equipment, as well as proposed modifications, necessary for automatic operations at the initiation of a seismic event.
We have reviewed this equipment as well as the reliability of the scram and valve actuation circuitry in the context of redundancy, power loss, operating experience, and functional testing and in-service surveillance of scram I
systems and components.
Furthermore, we have reviewed the response times for the scram action events for safe shutdown of the reactor.
Based on our evaluation, it is concluded that:
1.
The electric, instrumentation and control equipment, modified as proposed, will perform the necessary automatic actions of reactor scram, pressurizer isolation, emergency cooling valve operation and FFS initiation;
s 1 2.
The reliability of the scram and valve actuation 1
circuitry provides reasonable assurance that the necessary automatic actions will be performed when required; and 3.
The response times for the scram action events and the safe shutdown of the reactor are reasonable for use in evaluating the status of equipment during significant seismic loadings.
