LANCER is designed to satisfy all requirements related to RPV examinations as well as remedial
activities. Inspection equipment is capable of performing remote underwater ultrasound testing
using contact technique, eddy current and visual testing, taking specimens and grinding action or
other corrective action.
INSPECTION SCOPE
RPV shell circumferential and longitudinal welds
lower head (bottom) welds
inlet and outlet nozzle-to-shell welds
and inner radius areas, nozzle-to-safe
end welds and safe end-to-pipe welds
safety injection nozzles, nozzle to shell welds
and inner radius areas, nozzle-to-safe end welds
ligaments between the thread flange holes
RPV supports
interior surfaces
underwater UT inspection of the baffle
to former bolts
EFFECTORS
shell end effector
nozzle and inner radius end effector
bottom weld end effector (VVER)
baffle to former bolt end effector
KEY FEATURES
system modularity provides adaptation
to different sizes of RPVs (PWR and VVER type)
simultaneous inspection with two modules
reduces RPV inspection time
all baffle to former bolts reachable
from a single position of the robotic arm
data recording and processing sy
