O SECTION 1.0 1.1 Descrapt1on of pr opos ert chango, t e r, t, or exportmenti B Train Diesel Generator test simulating LOSP. This temporary procedurr. aligns the plant and simulates a Loss of Offuito Power. The plants response is recorded, documenting the proper operation of the Diesel Generators, the Sequencer and various safety related, soquenced loads. The test equipment is removed at the end of the test, and the plant is restored under the control of the Unit One Shift Supervisor. The test structure and methodology is similar to that of the recently completed ESFAS Surveillance procedures, 54055-1, and 34065-1. 1.2 rceu von for p r opo seri charge, test. or experiment: This UV (LOSP) is being simulated to assiet in the tro;619 shooting of the two A Train Diesel Generator (DGt trips experienced du~ing the Mbrch 20, 1970 LOSP event. This procedure will plats the D train of the ( plant into a configuration which is similar to that during the LOSP event. The response of the Diesel Generator and Sequencer will be closely monitored and recorded. The results of this procedure will be used to determine the root cause of the trips such that corrective action can ensure that the Diesel Generator an.4 9equencer are prepared to perform their safety i 4"6:iton should another LOSP occur. l

Yes No X F odanation: The Tech Specs for the affected components, Diesel Generators and Sequencer, are not af f ected by this temporary procedure. The tout of the l plants responsa to a LOSP is required to be l demonstrated at least every 10 months by Tech Spec 4.8.1.1.2. This is nortnally perf ormed by Engineering l Surveill ance procedures 54055-1 and 54065-1. This procedure performs the same testing as those procedures, and is required to assist in the trouble shooting of the DG trips. ThiG procedure represents no physical change to the plant. The Tech Spec assocluted with this test is 3/4.8.1.1.2.h.

1.0 PURPOSE

This procedure will test the safety related functions of the Unit One Train B Sequencer Panel. The Sequencer Test Panel is used to inject test signals into the' Sequencer. 2.0 PRECAUTIONS AND LIMITATIONS: 2.1 This test, once begun, shall be carried through to completion. If the test must be interrupted, then a detailed explanation of the interruption must ce entered into the log. 2.2 Operator assistance should be obtained to operate equipment as required. 2.3 Observe all appropria,te precautions and limitations in the plant operating procedures for the Sequencer during this test. l 2.4 Prior to the start of the test, the Responsible Engineer shall review the i Prerequisites and Initial Conditions, Section 4.0. 2.5 All procedural steps may be signed off by the . Responsible Engineer, Shift Supervisor, or i designated _ individual. 2.6 Do not perform this test with the DG1B operating in PARALLEL Mode. This procedure will force the Diesel Generator into UNIT Mode. 2.7 Section Sol and 5.2 are independent of each other and may be performed in any order. 2.8 Performing this test does not make the Sequencer In-operable. 2.9 All switches and lights are located on the Unit One Train B Sequencer Test Panel unless otherwise stated. 3.0 MEASUREMENT AND TEST EQUIPMENT NONE

The Train B 4160V Switchgear will be de-energized and the D-G oatput breaker wiki be locked out during the performance of this procedure. The Train B Sequencer will receive a U/V signal and will operate the sequencer output rel ays. 'This test will prove that the Sequencer can be manually reset by the U/V RESET SWITCH or relay K311 if the D-G output breaker does not close. It will also prove that the Sequencer cannot be reset by the U/V RESET SWITCH or relay K311 while the D-G output breaker is closed and the Sequencer is cycling. 1.2 Reason for proposed change, tast, or experi mo 's This procedure is being performed as a functional test for modifications made by DCP 88-V1N0070.

1. 3 Does the proposed change involve.a chGnge to Technical Specifications?

Yes No X E:< p i an at i on s This is a functional test of modifications made in the reset icgic of the Sequencer'and does not require a change to the Technical Specifications. Tech. Spec. sections 3/4.3.2 and 4.0.1.1.2.h do not address l testing of the sequencer with a de-energized buss. l 1.4 Does the propoued change involve a change in the facility as described in the FSAR? Yes No X l l Explanations This procedure does not involve a change in -the facility as described in FSAR sections 8.3.1.1.2.H or 8.3.1.1.3.F.
