NEEDED TO DO PROCEDURE 3.1 Data Sheet I (Enclosure 1) 3.2 FP-601, Fuel Ha ' ling Equipment Operations Page 1 SP-670 Date 3/23/78 Rev. 3

i 4.0 SPECIAL CONDITIONS OR REQUIREMENTS I 4.1 During lifts to =4n4=n= loads or overload settings, do not exceed the expected load values by more than approximately 100 lbs; if automatic overload actuations do not occur do not

. proceed with Surveillance Procedure. Notify the Shift Supervisor.

5.0 EQUIPMENT REQUIRED None 6.0 PROCEDURE -

6.1 Demonstrate the OPERABILITY of the Mais Fuel Handling Bridge (FHCR-1) by performing the following steps:

6.1.1 Startup FHCR-1 in accordance with the startup procedure in FP-601, Fuel Handling Equipment Operation.

6.1.2 Place the main fuel hoist Dillon load cell range switch in position "A" (0 to 3000 lbs.) .

6.1.3 Position the main fuel handling grapple over the load testing fixture.. To position the auxiliary fuel handling grapple over the test fixture, the bridge left and trolly interlock bypass must be actuated.

6.1.4 Lower the main fuel handling grapple and engage the mating fitting on the test fixture. Visually check for proper engage-ment of grapple with test fixture.

l 6.1.5 . Slowly raise the main fuel handling grapple, using the "Jeg" button, until the hoist stops and the red " Overload" indicator light comes on. Record the fuel Dillon readout on Data Sheet I.

l- CAUTION: The overload cut-of f should actuate at or before reaching 2750 lbs. Do not exceed 2800 lbs.

6.1.6 Slowly-lower the main fuel handling grapple until the fuel Dillon readout indicated approximately 2000 lbs.

6.1.7 Place the main fuel hoist Dillon load cell range switch in position "B" (3,000 to 6,000 lbs.).

6.1.8 Place the main fuel hoist' overload bypass switch in the "On" position.

6.1.9 Slowly raise the main fuel handling grapple, using the "J0G" button or manual handwheel, until the fuel Dillon readout indi-cates a load of 3050 t'o 3100 lbs.

Record the reading on Data Sheet I.

6.1.10 Lower the main fuel handling grapple to less than 3000 lbs. using the manual handwheel (grapple will not lower with jog button due to low load interlock being actuated by range switch in "B" position) then use jog button and disengage the test fixture visually verifying the disengagement.

6.1.11 Raise the main fuel handling grapple. Return the fuel hoist overload bypass switch to the "Off" position. Return the fuel hoist Dillon load cell range switch to the "A" (0 to 3,000 lbs.) position.

l i .

6.1.12 Complete the applicable section of the reactor building bridges log shttt attached to the bridge consoles.

6.2 Demonstrate the OPERABILI1T of the Auxiliary Fuel Handling Bridge FHCR-2 by performing the following steps:

6.2.1 Startup FHCR-2 in accordance with the startup procedure in FP-601, Fuel Handling Equipment Operation.

6.2.2 Repeat Steps 6.1.2 through 6.1.11 except for the auxiliary fuel handling hoist, recording appropriate data on Data Sheet I.

6.2.3 Complete the applicable section of the reactor building bridges log sheet attached to the bridge consoles.

6.3 Return both FHCR-1 and FHt'2-2 bridges to their normal park locations and then, if applicable, shut'down both bridges in accordance with FP-601, Fuel Handling Equipment Operation.

6.4 No restoration is required.

6. 5 Notify the Shif t Supervisor of the completion and results of this Surveillance Procedure.
