0 1.0 Pur ose and Ob ective The purpose of this procedure is to verify the on-line operation of the Turbine Mechanical Overspeed Protection Mechanism.

2.0 Prere uisites and Initial Conditions Initials/Date 2.1 Initial Criticality and Low Power Physics testing plateau is complete per 1-9100-S"01.

2.2 Reactor power is less than 20Z.

2.3 The Turbine-Generator has been at

> 10Z Load (95 145 MW) for eight (8) hours or more.

2.4 All test personnel have been briefed on their responsibility during the test by the Po~er Ascension Lead Test Engind'er.

2.5 An operator is standing by the trip lever at the Governor

Pedestal, in contact with the Control Room.

2e6 Communications have been established.

2.7 A frequency counter has been installed at the Governor Pedestal to allow the operator to see the speed locally.

(Spare speed pickup, terminal Box "A", TB1, points 40,41 and 42 GRND) 2.8 The operational status of the unit will allow the test plant prerequisites to be established and performance of the test to occur without violation of Technical Specifications or creation of conditions adverse to safe operation.

2.9 The Shift Foreman has granted permission to perform this test by

~si nin in the space provided heiov.

0 3.0 Precautions 3.1 The Turbine speed should not be allowed to exceed 2010 RPM (111.6Z)

~ If the unit has not tripped when this speed is

reached, the turbine is to be tripped manually.

3.2 Should bearing vibration levels increase past the alarm point of 7 mils awhile above 1800 rpm, this test should proceed only with the approval of the Manager-Operations.

3.3 All work and testing will be performed in accordance with the CP&L Safety Manual.
