Insanity at Vogtle In Pulling Rod Groups

It is like steering your car to the right, then the car veers to the right! Why didn't pre start-up testing catch this?

"control rods were inserted with Control Bank D the expected group to insert. Control Bank A inserted instead of Control Bank D"

This is pretty pathetic nuclear plant maintenance.

MANUAL REACTOR TRIP DURING REACTOR STARTUP "VEGP [Vogtle Electric Generating Plant] Unit 2 was performing startup and had taken reactor critical at 0929 EDT. When attempting to stabilize power to collect critical data, control rods were inserted with Control Bank D the expected group to insert. Control Bank A inserted instead of Control Bank D. Power had reached 6 E-2 percent as indicated by IR [intermediate range] indication when control room crew performed a manual reactor trip. AFW [auxiliary feed water] was in service to support plant conditions prior to the trip and did not receive any actuation signal. All equipment operated as expected. Unit 2 is currently stable in Mode 3 at normal operating temperature and pressure." The licensee has notified the NRC Resident Inspector.
