Davis-Besse Lessons Learned Task Force
After extensive degradation was discovered in the reactor pressure vessel
(RPV) head at the Davis-Bessie Nuclear Power Station, the NRC Executive
Director of Operations (EDO) established a lessons
learned task force 
to evaluate NRC regulatory processes for ensuring RPV head integrity and
to recommend improvements for either the NRC or the nuclear industry.
On September 30, 2002, the task force reported
its findings to a senior management review team, including 51 recommendations
for the NRC to take to address factors that contributed to the Davis-Besse
event.
In its report of November
26, 2002 ,
the senior management review team endorsed all but two task force’s
recommendations. The approved recommendations were placed into four categories:
(1) assessment of stress corrosion cracking; (2) assessment of operating
experience, integration of operating experience into training, and review
of program effectiveness; (3) evaluation of inspection, assessment, and
project management guidance; and (4) assessment of barrier integrity requirements.
The review team assigned each recommendation a priority and directed that
the highest priority items be addressed by action plans. All other items
were to be integrated into the operational planning activities of the
lead offices. On January 3, 2003, the EDO issued a tasking
memorandum
to the directors of the Offices of Nuclear Reactor Regulation (NRR) and
Nuclear Regulatory Research (RES), instructing them to develop a plan
for accomplishing the actions recommended by the review team. RES and
NRR issued the plan on
March 7, 2003.
