ATTACHMENT Summary Description of Change (ST-29)
Regulatory Guide 1.68 (Revision 2, August 1978), Appendix A, paragraph 5.s requires that the recirculation flow control system be calibrated as necessary and performance verified, and paragraph 5.h.h requires that the dynamic response of the plant to design load swings be demonstrated to be in accordance with design. Startup Test 29, Recirculation Flow Control System, determines the plant response to changes in recirculation flow and optimizes settings of the recirculation flow controller.
Testing is performed over a wide range of power / flow conditions.
It is proposed to simplify the testing by reducing the number of intermediate flow conditions and testing inputs (ramp and step demands) and to delete the Automatic Load Following (ALF) testing and relax associated response criteria.
DISCUSSION Response of the system is determined by analyzing test data and comparing to acceptance criteria which define the required system performance. The testing of the Recirculation Flow Control System follows a " building block" approach while the plant is ascending from low to high power levels. Components and inner control loops are tested first, followed by drive flow control and plant power maneuvers to adjust and then demonstrate the outer loop controller performance. Testing is performed to demonstrate the capability of the system over the entire flow control range.
Prior to the power ascension test program, predictions of system behavior are performed to aid in the tuning of the Recirculation Flow Control System. In addition, benchmark testing of the flow control valve recirculation system and successful startup test results from several flow control valve plants (Kuosheng 1 and 2, LaSalle 1 and 2 and Leibstadt) provides valuable experience which can be used to reduce the number of test cases while still fulfilling the purpose of Startup Test 29. As a result, the number of intermediate flow conditions and test inputs (ramp and step _ demands) required to achieve the desired system performance can be reduced.
Testing of the Recirculation Flow Control System is also performed in the . Automatic Load Following (ALF) mode of operation. To provide acceptable response in the ALF mode of operation,- the acceptance criteria for the response of all control-loops are more stringent than those required for systems operating without ALF. Since the ALF mode is not a safety related function and consists of non-essential equipment, the ALF mode can be disabled. With the ALF mode disabled, no testing of

Page 3 RBG- 23507 the Recirculation Flow Control System is required in this mode.
In addition, the response criteria for the inner control loops can be relaxed, reflecting the deletion of the ALF requirements.
The relaxed acceptance criteria will still provide assurance that the plant will operate in accordance with design and that the assumptions used in the safety analysis remain valid for the Recirculation Flow Control System.
CONCLUSION By using pretest analysis and experience from previous flow control valve plant startup testing, the objectives of Regulatory Guide 1.68 (Revision 2, August 1978), Appendix A, paragraphs 5.s and 5.h.h can be satisfied with the proposed simplified testing.
Removal of the ALF function will not affect any safety related systems or the safe operation of the plant and therefore deletion of the ALF testing does not involve an unreviewed safety question. The acceptance criteria for the simplified test are consistent with assumptions used in the safety analysis and will be satisfied by the simplified testing and therefore do not involve an unreviewed safety question. Therefore, Startup Test 29, Recirculation Flow Control System, can be simplified by reducing the number of intermediate flow conditions and test inputs (ramp and step demands) and by deleting the ALF testing and relaxing associated acceptance criteria.
