SUBJECT: NRC SPECIAL INSPECTION REPORT NOS. 50-295/97007; 50-304/97007

Dear Mr. Mueller:

This refers to the special inspection conducted by A.Vogel, D. Calhoun, M. Bailey, and )

G. Galletti of this office on March 12 through April 7.8,1997, at your Zion Station, l

Units 1 and 2.' The purpose of the inspection wen to review the circumstances

surrounding the improper control rod manipulation event during a Unit 1 shutdown on

February 21,1997, and two subsequent operational events; a missed Technical

Specification Limiting Condition for Operation action statement and a Unit 1 hydraulic

transient event.' The first event is also the subject of NRC Augmented Inspection Team

inspection Report No. 50-295/97006.

l

The enclosed report presents the results of this inspection. Based on the results of this

inspection, seventeen examples of apparent violations were identified and are being

considered for escalated enforcement action in accordance with the " General Statement of

Policy and Procedure for NRC Enforcement Actions" (Enforcement Policy), NUREG-1600. j

i

The apparent violations reflect operational weaknesses which contributed to the )

breakdown in the command and control of the Unit 1 shutdown evolution and similar

deficiencies exhibited in the other events. Twelve examples of an apparent violation,

involving failures to follow procedure, did not individually result in actual safety

consequences. However, the number of examples reflect extensive deficiencies in control

room operating practices, such as inadequate pre-evolutionary preparations, poor

communications, and inadequate supervision. A second apparent violation, involving the

control room operators' failure to recognize the Technical Specification implications of

removing all three channels of a reactor coolant loop flow indicator from service, occurred.

soon after the control rod manipulation event and reflected similar operator command and  !

control weaknesses. A third apparent violation concerned four examples of inadequate

corrective actions. .The first example involved the failure to implement adequate, I

immediate corrective actions following the identification of licensed operator performance

problems that occurred during the control rod manipulation event. The remaining three

examples involved the failure to implement effective long term corrective actions to  ;

preclude the recurrence of previous reactivity management problems and operator

deficiencies. The failure to adequately address these previously identified operational ,

performance weaknesses was significant because the relapse of these problems directly *

contributed to the occurrence of the February 21, event.

,

No Notice of Violation is presently being issued for these inspection findings. In addition,

please be advised that the number and characterization of apparent violations described in

I

the enclosed inspection report may change as a result of further NRC review.

A pre-decisional enforcement conference will be scheduled to discuss these apparent

violations. The decision to hold a pre-decisional enforcement conference does not mean

l that the NRC has determined that a violation has occurred or that enforcement action will

l be taken. This conference is being held to obtain information to enable the NRC to make

an enforcement decision, such as a common understanding of the facts, root causes,

missed opportunities to identify the apparent violations sooner, corrective actions,

significance of the issues and the need for lasting and effective corrective action.

In addition, this is an opportunity for you to point out any errors in our inspection report

,. and for you to provide any information concerning your perspectives on: (1) the severity

j of the violations; (2) the application of the factors that the NRC considers when it

i determines the amount of a civil penalty that may be assessed in accordance with

Section VI.B.2 of the Enforcement Policy; and (3) any other application of the Enforcement

!

Policy to this case, including the exercise of discretion in accordance with Section Vll.

l

You will be advised by separate correspondence of the results of our deliberations on this

matter. No response regarding these apparent violations is required at this time.

l

In accordance with 10 CFR 2.790 of the NRC's " Rules of Practice," a copy of this letter

and its enclosure will be placed in the NRC Public Document Room.

l Sincerely,

)
