I Statement of Violation Test Procedure' Adequacy and Implementation Technical Specification 6.8,1 states, in part, that written procedures shall be established, implemented, and maintained as recommended in Appendix A of Regulatory Guide 1.33, Revision 2, February 1978.
Contrary to the above, on January 26, 1988, the licensee failed to reestablish the proper testing configuration as required by the note in Section 4.7 of Station Procedure ITEP07-AF-0010, Revision 0, "Auxiliary Feedwater Proof Test," after interrupting the test to feed steam generators. This resulted in obtaining improper test results requiring a repeat of the test. On February 5, 1988, the licensee implemented an inadequate procedure. Station Procedure 1 PEPO 4-ZL-0024, Revision 3, "Rod Drop Time Measurement" did not provide for closing the reactor trip creakers, nor did the procedure provide controls to ensure that the same breakers were opened upon recovering from the test.
II. Houston Lighting & Power Position Houston Lighting & Power does not contest the violation.
III. Reason for Violation The discrepancy identified during the conduct of the Auxiliary Feedwater Proof Test is attributed to inattention to detail on the part of the test coordinator.
The lack of control associated with the reactor trip breakers in procedure 1 PEP 04-ZL-0024, Rod Drop Time Measurement, was caused by an inaderuate review during the generation and approval cycle, in that it
) was believed that the reactor trip breakers were operated as part of the procedure for starting / securing the Rod Control System Motor Generator sets. If this had been true the prerequisite section would have ensured the breakers closed and the breakers would have been opened when the Shift Supervisors secured the M/G set after being informed that the testing had been completed.

Procedure IPEPO4-ZL-0024, Rod Drop Time Measurement, was changed to incorporate specific steps to control the position of the reactor trip breakers. This was done to provide consistency between various plant procedures.
V. Corrective Actions That Will Be Taken No further corrective actions are deemed necessary.
