A. Removal (Typical)
(1). Remove VSCS actuator (5) (ref. Proce­
dure 77.A.).
(2). Measure the dimension between the
end of VSCS actuator (5) and the end of
control rod (16).
(a). Record the dimension.
(3). Loosen nut (17).
(4). Remove control rod (16).
B. Installation (Typical)
Consumable Materials
(Ref. CSP − SPM)
Item Nomenclature
C220 Compound, Anti − Seize
C702 Lockwire
Compound, Anti-Seize (C220)
(1). Apply anti-seize compound (C220) to
the threads in control rod.
(2). Clean anti-seize compound (C220) from
the end of control rod (16).
(3). Install control rod (16):
(a). Adjust the control rod to dimension
recorded in Step 78.A.(2).(a).
(b). Torque nut (17).
(c). Safety with lockwire (C702).
(4). If there is no record of the control rod
length, do these steps:
(a). For the left VSCS control rod:
1). Measure the distance from the
VSCS actuator rod end center to
end of the actuator ram and record
as Dimension A.
2). Subtract Dimension A from 10.7
inch (272 mm) and record as
Dimension B.
3). Adjust the control rod so that the
distance between the end of VSCS
actuator and the center of the rod
end is the same as Dimension B.
4). Torque nut (17).
5). Safety with lockwire (C702).
(b). For the right VSCS control rod:
1). Measure distance from VSCS
actuator rod end center to end of
actuator ram and record as Dimen­
sion A.
2). Subtract Dimension A from 11.4
inch (290 mm) and record as
Dimension B.
