SUMMARY

OF JUNE 22,1998, MEETING WITH POWER CONTROL SERVICES AND WOODWARD GOVERNOR COMPANY On June 22,1998, representatives of Power Control Services (PCS) and Woodward Governor Company (Woodward) met with U.S. Nuclear Regulatory Commission (NRC) staff to present the Woodward model 505 microprocessor-based turbine controls. The 505 digital control is an existing commercial product that PCS and Woodward are considering offering for use in nuclear safety systems. Attachment 1 provides a list of attendees. The presentation material from the meeting is included as Attachment 2; none of this information was identified as being proprietary.

Following an overview of the 505 digital controller design and capabilities, the staff, PCS and Woodward discussed the criteria that the staff would use to review the control;er. PCS and Woodward noted that they were familiar with the general NRC requirements and criteria as a result of reviews of their previous mechanical systems but they had not previously undergone a computer-based product review. The staff directed them to the Standard Review Plan (SRP)

Chapter 7 (NUREG-0800, June 1997), " Instrumentation and Controls" with a particular emphasis on Branch Technical Position 14, " Guidance on Software Reviews for Digital Computer-Based Instrumentation and Control Systems." The staff discussed how a review would be conducted in accordance with the SRP. PCS and Woodward described the qualification testing that had been completed. The staff described some examples of commercial products that were latter dedicated for use in a safety system and the possibility that some documentation and/or testing may need to be supplemented.

The options that PCS and Woodward have for obtaining a NRC safety evaluation report were discussed. PCS and Woodward indicated that their preference would be for PCS to assemble the needed information and submit a topical report. They would include the electro-hydraulic part of the turbine control system as well as the microprocessor control. The staff noted that a N!

Introductions

2.

' Reasons Power Control Services and Woodward Governor Company requested meeting.

Determine the economic feasibility of pursuing the qualification.

Obtain complete listing of qualification requirements for Terry Turbine Governor Retrofit Package.

l:

3.

Explain c,omposition of proposed retrofit package - Woodward Governor Company will give l

presentation.

l 4.

Woodward Governor Company to review functions ofindividual components in the proposed package.

5.

Discussion of 505 Digital Control Discuss the portions of the software that will be utilized by the proposed control system.

e 6.

Software Validation Issues and Rec uirements What software standards shoukl be used in the V & V process?

a e

Step-by-step walk through of software validation tasks and requirements 7.

EMI Testing Issues and Requirements - (also see Electromagnetic Compatibility Compliance Summary Document contained in this folder).

l Radiated Susceptibility - Testing per MIL-STD 461 is at one (1) meter. Presently Woodward Governor Company's tests are being run at a distance of three (3) meters in the frequency range of 80 to 1000 MHz. In this range they meet the European requirements of fieki uniformity as described in ENV 50140. Would it be acceptable to run a portion of this ast at a 3 meter distance maintaining a 10 V/M field?

i Conducted Susceptibility- (30 to 50 KHZ, CS101) This is a test for input power only. The power requirements vetween MII STD 461C and MIL-STD 461D are different; 50 Watts verses 80 Watts Wouki 50 Watts be acceptable? If we do try to increase the output level to 80 Watts, we may be unable to produce the required 6.3 VRMS level below 100 Hz. Is this acceptable?

Surge - The pulse required would be difficult to inject using an injection probe. Woodward e

Governor Company has contacted two injection probe manufacturers who have c uestioned

' the ability to do this test with an injection probe. Taking this into account, Wooc. ward Governor Company would prefer to use capacitive coupling as described in IEC 801-5. Is this acceptable? -

EFT - Again there seems to be some question as to using an injection probe for this test.

e One probe manufacturer has a probe with the required bandwidth, but the maximum voltage induced is limited to 2,100 Volts. Woodward Governor Company wouki like to use the capacitive coupling method as described in IEC 801-4. Is this acceptable?

9 1 l COMPARISON OF EGM CONTROL SYSTEM VERSUS 505 CONTROL SYSTEM JUNE 1998 l EGM Ramp Gen-Sig Conv. Dropping Resistor EGR actuator Remote Servo 505 Control TM25 Actuator TG gov for pump Maintenance, Advantages, Benefits EGM system dropping resistor requires the resistor be changed out every two years. 580.00 for rnaterial plus labor and down tune. Not required with 505. Ramp initiation switch can be eliminated from the steam valve. Less equipment in the system to maintain and monitor. We are planning i system package so all plants will use the same equipment and same part numbers. Using the TG as a pump sump means self contamed oil system and is not dependent on turbine oil. Contamination and supply oil for start up becomes a nummal issue. Spare 505 controls in storage can be powered up simply by providing 115 VAC power from a wall outlet. This is necessary and should be donc periodically to maintain the capacitors on the power supply inputs. He EGM family is obsolete and parts availability are an issue. The same is about to be true of the equipment discussed here as part of the system with the EGM. He 505 is current technology wnh a proven track record. The same is true of the actuator. The 505 offers VASTLY improved fast start control capability! i The 505 display window reads RPM as well as other parameters so the need for an auxiliary tach is l climmated. We can still feed the auxiliary tach if so desired. Question The input water level speed bias signal is 4-20 MA at some plants and 10-50 MA at other plants. We s would like these to all be 4-20 MA. g j l I
