Dear Mr. Farrar:

L. 01shan D. Hickman

SUBJECT:

50% LOAD REDUCTION STARTUP TEST By letter dated December 11, 1986 you proposed a revision to the Initial Test Program for Byron Station, Unit 2 and Braidwood Station, Units 1 and 2. You proposed to delete the 50% load reduction test from 75% power and to allow minimal manual intervention when conducting the 50% load reduction test from 100% power.

Regulatory Guide 1.68, Appendix A, Paragraph 5.h.h, states that the Initial Test Program should demonstrate that the dynamic response of the plant to the design load swings is in accordance with design. As discussed in FSAR Section 10.2.1, the plant is designed to accept a maximum step load rejection from 100% to 50% power without reactor trip. Therefore, a 50% load reduction test from 75% power is not needed to verify plant design. Furthemore, minimal manual intervention,~as called for in the operating procedures,-is not prohibited by the Regulatory Guide. Therefore, the revisions to this test that you proposed in your December 11, 1986 letter are acceptable for Byron 2 and Braidwood I and 2.

Sincerely, Leon rd N. Olshan, Project Manager i

100% power.

' Regulatory Guide 1.68, Appendix ~ A, Paragraph 5.h.h. states that the Initial 1 Test Program should demonstrate that the dynamic response of the plant to _the design load swings is in accordance with design. The plant is designed to accommodate step load changes of-up to 110% and this design is verified by the 10% load swing test described in FSAR Table 14.2-88. The 50% load reduction test described in FSAR Table 14.2-89 is not required by Regulatory Guide 1.68.

Therefore, the revisions to this test that you proposed in your December 11, 1986 letter are acceptable for Byron 2 and Braidwood -1 and 2.
