MEMORANDUM FOR:
Paul M. Byron, Senior Resident Inspector, Fermi 2 FROM:
Charles H. Weil Investigation and Compliance Specialist
SUBJECT:
FERMI SAFETEAM CONCERN NO. 676 (50-341)
Reference:
Your July 1, 1985 memo, same subject.
l SAFETEAM Concern No. 676 was reviewed by the Director, )ffice of Investigations Region III Field Office and the Region III Investigation and Compliance Specialist.
It was concluded that an employee's termination for
" sexual aggressive actions" was not a matter for investigation by the Nuclear Regulatory Comission. Rather, the Detroit Edison SAFETEAM should inform the person at whom the action was' directed (the victim) that investigations of sexual discrimination / harassment are performed by the U. S. Equal Employment Opportunity Comission.

INADVERTENT CRITICALITY i Julv 15, 1985, the licensee reported to the Senior Resident Inspector that an igie., ering analysis of reactor startup activities on July 2,1985, had determined iat the reactor had been brought critical at that time without the shift supervisor talizing that criticality had been achieved.
(Fenni 2 had its initial criticality on Jne 21, 1985.)
Jring the reactor startup on July 2, a reactor operator moved 11 control rods in Group 3 to le full out position. The operator failed to follow licensee procedures in moving the 3ds--they were moved to the full out position, instead of being moved 1 steps, in accordance with the procedure. The reactor operator noticed the power
- vel increasing faster than hc anticipated, and he promptly returned the 11 rods to the ally inserted position.
he shift supervisor then reviewed the operator's actions, and detemined that the reactor ad not gone critical. Startup activities then resumed using the step-by-step procedure, and riticality was achieved consistent with the expected estimated critical position.
ive days after the incident, a reactor engineer concluded that the reactor had a fact gone critical during the initial Group 3 rod movements.
Ggion III (Chicago) was notified of the inadvertent criticality at 1:30 p.m.,
@DT) July 15, 1985. The licensee has initiated an investigation of thr: criticality acident. An NRC technical specialist has been dispatched to review the ircumstances of the incident.
The Office of Nuclear Reactor Regulation has Gen infomed. Region III is also reviewing the time lapse between the event, the etermination of criticality, and its being reported to the NRC.
Ote plant is currently operating at 2 per cent power.
he State of Michigan will be informed, his infomation is cur ent as of 7 a.m., July 16, 1985.
