DPR-58 and DPR-74 GENERIC LETTER 83-28 ANTICIPATED TRANSIENT WITHOUT SCRAM (ATWS) MITIGATION SYSTEMS ACTUATION CIRCUITRY (AMSAC) ADDITIONAL INFORtfATION U.S. Nuclear Regulatory Commission Attn: Document Control Desk Washington, D.C. 20555 Attn: T. E. Murley March 31, 1988
Dear Dr. Murley:
The purpose of this letter is to respond to your staff's January 27, 1988 telephone request to provide additional information on our AMSAC plant specific design.
On January 21, 1988 your staff telecopied a list of questions concerning our AMSAC design. During a January 27, 1988 teleconference, several of the questions were resolved. The following information (numbered according to the telecopy sent by your staff on January 21, 1988) responds to the additional information requested during the January 27, 1988 teleconference.
From 11-7-86 Submittal
- 1. No mention of the reset of the AFW pumps or the turbine trip circuits. Need a statement regarding the manual reset.
Response: Once initiated, AMSAC will seal itself in. It requires operator action to reset the AMSAC logic circuit at the system level. The motor driven auxiliary feed pumps, the turbine driven auxiliary feed pump, and the main turbine, will be reset through their own controls. To reiterate, when AMSAC is reset at the system level, the turbine and auxiliary feed water systems are not automatically reset.

- 2. Attachment 1 - Appendix A a) No mention of the MCF potential current.
b) Need make and model number of both the analog and digital isolators.
c) Need copy of test report.
Response a): For information concerning how the maximum credible fault (MCF) voltages were determined, please refer to our June 25, 1987 letter (AEP:NRC:0838Z).
To determine the MCF current associated with the 128v DC MCF voltage, three assumptions were made:
- 1) Power out of the power supply equals power into the power supply.
- 2) The 3/8-ampere instrument power supply input fuse passes a momentary current of 1.5 times its nominal rating.
- 3) The maximum instrument power supply voltage of 84v DC is delivered through the 1/8-ampere output fuse which does not open.
Using the above assumptions yields a MCF current of 0.80 amperes for the 128v DC MCF voltage.
To determine the MCF current associated with the 110v AC MCF voltage, two source voltages were analyzed.
- 1) The AMSAC analog isolation devices source voltage circuits are protected by 5-ampere fuses. Assuming that the fuse passes a momentary current of 1.5 times its nominal rating yields a current of 7.5 amperes.
- 2) The AC devices in the AMSAC cabinet are powered by a 250v DC to 120v 1 kVA AC inverter. This inverter has a nominal full load current rating of 10 amperes and is current limited by the inverter itself at 200$ , i.e., 20 amperes.
AHSAC the DC circuits would see this 200$ only input fuses and the AC output circuit if both breakers fail.

Dr. T. E. Murley AEP:NRC:0838AE 20 amperes is the largest of the currents for the two source voltages analyzed, so it was selected as the MCF current associated with the 110v AC MCF voltage.
Response b): We plan to use the test GE HFA relays (Model No.
12 HFA 151A9H) ~ These relays will function as the output isolators. The maximum credible voltage is 280v DC (When battery is on equalize).
The maximum credible current which will be present if the coil were completely shorted out is approximately 275 amps. However, the coil resistance is 415 ohms for a typical 115 VAC HFA relay. The expected current through the HFA coil is:
I - 280v DC .67 amps 415 ohms Response c): We are in the process of designing and assembling our test program and will submit the test report under separate cover as agreed.
From 12-18-87 Submittal
- 9. ualit Assurance a) No commitment to GL 85-06 as it applies that is designated non-Class to the AMSAC equipment 1E.
b) Compare the existing non-1E QA procedure against the guidelines presented in GL 85-06 and modify the existing procedure as necessary of GL 85-06.
to bring it within the guidelines Response a): The use of non-Class 1E AMSAC equipment will be minimal. Equipment that must be purchased non-Class 1E will be treated in accordance with GL 85-06. The applicable portions of the Quality Assurance Program as set forth in the "Updated Quality Assurance Program Description for the Donald C. Cook Nuclear Plant" (FSAR Chapter 1.7) will be applicable to those items of AMSAC equipment designated Class 1E.
Response b): The normal AEPSC engineering, design, procurement and operating practices for non-Class 1E equipment
Dr. T. E. Murley AEP:NRC:0838AE are similar to the practices outlined in the FSAR for Class 1E equipment. We have also compared our existing non-Class 1E practices (though not necessarily proceduralized) with the criteria established in GL 85-06 and believe we meet the guidance of GL 85-06. We understand 85-06 acknowledges that non-class 1E practices may not necessarily be proceduralized.
From 12-18-87 Submittal
- 20. ~B asses means for attachment 2 5 d) Where is the "AMSAC Test Successful" light located?
In addition, during the January 27, 1988 teleconference, your staff requested that we describe the latest annunciation scheme for AHSAC and provide a copy of the logic diagram which indicates from where the signals are coming.
Response: The Detailed Control: Room Design Review (DCRDR) human factors engineering has been completed. The annunciator/alarming scheme is as follows:
a) When AMSAC is in the disable or bypass/test positions, an indicating light will illuminate.
b) The AMSAC enabled indicating light will illuminate when the power level is above 40$ or in the bypass/test mode. When in the bypass/test mode, the AMSAC syste'm is tested up to but not including the initiating relays.
c) When AHSAC is actuated, drop no. 14 on annunciator bank no. 212 on the DTU panel will illuminate stating "AMSAC Actuated." The input for this drop "
will be one of th'e AMSAC initiate relays.
d) When a loss of power to the AMSAC logic bus occurs, drop no. 15 on annunciator bank no. 212 on the DTU panel will illuminate stating "AHSAC Control Bus Abnormal." The signal will originate from a GE HGA relay which is connected across the output side (AC) of the inverter.
e) When AMSAC is in the bypass/test mode and feedwater flow to 3 of 4 flow loops is simulated, if a low the AHSAC test relay will energize and seal itself in illuminating an indicating light in the AMSAC cabinet indicating AHSAC test successful. The reset, AMSAC control switch 101-AM-1 is placed in "Reset."
j4 gP
Dr. T. E. Murley AEP'NRC:0838AE f) Once AMSAC is returned to the normal mode of operation (from disable or bypass/test) the initiate relays are continuity checked with a push button switch. The push button will produce current flow through the relay coil to verify continuity and illuminate an indicating light to verify that the circuit is continuous. The indicating light will be labelled "AMSAC Available "
g) When AMSAC is in the bypass/test mode, we have the capability to test the AHSAC logic circuitry (excluding the initiate relays). If we simulate low feedwater flow and the circuit is functioning properly, we will illuminate an indicating light in
'the AMSAC cabinet which states "AMSAC test successful." The location of the'AMSAC cabinet is in the Unit P2 control room behind the Axial Power Distribution Monitoring System.
Attachment No. 1 contains the revised AMSAC logic diagram.
The revisions are described below:
- 1. When AMSAC is in the bypass/test mode, the AMSAC initiate relays are disabled.
- 2. When AHSAC is in the bypass/test mode, a simulated signal indicating above 40$ power is used to test AMSAC logic.
The above mentioned revisions to the logic diagram are identified by dotted lines.
Attachment No. 2 contains the DCRDR information which has been previously submitted. Please note that we plan to use a red handle for the manual initiate switch 101-AH-1. We changed the positions on 101-AH-2 i.e., normal and bypass positions were exchanged as well as the status lights above the switch.
From 12-18-87 Submittal
- 12. Com letion of Miti atin Action a) This response should have been changed (C-20).
Response a): The Westinghouse Owners Group low feed flow design delays the unlocking of AMSAC (C-20 signal) for a
Dr. T. E. Murley .AEP:NRC:0838AE minimum of sixty seconds after the variable timer has timed out. WCAP-10858 P-A, Rev. 1 provided the basis for this design. Its implementation will be consistent with existing plant turbine trip and existing auxiliary feedwater control circuit requirements. Initial plant checkout testing will verify that once initiated, AMSAC will go to completion. Our design requires a deliberate action from the operator to reset the AMSAC system.
The AMSAC system will be continuously monitored in the control room.
