This resulted in a 30 gallon, then a 20 gallon dilution of the Reactor Coolant System (RCS).At this time, a flux map was being run.Negative reactivity was being added due to Xenon buildup.In order to minimize flux distortion,.

control rod motion was being minimized, and to counter the negative reactivity addition, the RCS was being diluted.The RCO directly supervised both dilutions.

No other manipulations were made by the non-licensed person.The cause of the non-licensed person manipulating a control was personnel error, in that the RCO failed to comply with the requirements of 10CFR50.54(i) and 10CFR55.3.

Contributing to the event were inadequate procedures and training on the requirements of 10CFR50.54(i) and 10CFR55.3.

The Plant Supervisor-Nuclear (PSN)counseled the RCO and the non-licensed person.The PSN discussed the event at the shift turnover meeting.A memo explaining the requirements of 10CFR50.54(i) was issued.All license'd'perators have been required to read and sign the memo prior to assuming shift responsibility.

Additional corrective actions will be taken upon evaluation of the results of ongoing investigations.

The first occasion resulted in" a 30 gallon dilution of the Reactor Coolant System (RCS), and the second occasion resulted in a 20 gallon dilution.At the time of the event, a 30X power flux map was being run.As a result of Xenon buildup, negative reactivity was being added.In order to minimize flux distortion, control rod motion was being minimized, and to counter the negative reactivity addition, boron was being removed by diluting the RCS.The dilution was being performed by adding preset quantities of water to the RCS'eriodically.

During this event, the Reactor Control Operator (RCO)preset the water quantity to 30 gallons, then permitted a non-licensed person to turn the Reactor Control Make-up Switch to the Start position.The system response to the 30 gallon dilution was not sufficient, and the above evolution was repeated with the water quantity preset by the RCO to 20 gallons.The RCO directly supervised both dilutions.

No other manipulations were made by the non-licensed person.CAUSE OF EUENT A thorough investigation was performed independently by both the plant Quality Assurance department and the Operations department.

The investigations were performed.

by personnel interviews, review of documents, personnel statements, notes, and reports of management personnel who had been on shift.The investigations had the following main goals: a)review the timeliness of management actions b)determine if this was an isolated event c)review for potential reportability d)determine existing procedural requirements addressing this event e)determine training performed on this 10CFR50.54(i) and 10CFR55.3 requirement The investigations concluded that the cause of the non-licensed person manipulating a con ro control which directly affected the reactivity of the reactor was personnel error, in that the RCO failed to comply with the requirements of 10CFR50.54(i) an d 10CFR55.3..

Contributing to the absence of a full understanding of regulatory requirements were the following:

1)lant procedures and training did not detail the requirements of 10CFR50.54(i) p an pr c and 10CFR55.3, 2)plant procedures were not revised to address the revision of 10CFR55.3 which became effective in May, 1987 3)no training which addressed the revisions of 10CFR55.3 was performed.

The evolutions performed by the non-licensed person were controlled and directly supervised by the RCO.Even though as a result of this event there were no safety consequences, the event represents a violation of regulatory requirements.

This event is not a reportable event under either 10CFR50.?2 or 10CFR50.73.

However, Florida Power and Light is voluntarily submitting this Licensee Event Report because of the generic concerns and lessons to be learned, in addition to the safety significance of this'vent.

CORRECTIVE ACTIONS Turkey Point has in place a Management on Shift program, the aim of which is to observe and improve Turkey Point s operation.

'he manipulation cited in this event was observed by the management on shift at that time.The Operations Supervisor was.notified of this event the following morning (September 14), and the Operations Superintendent and Plant Manager were notified at 1830 on September 14.The following immediate corrective actions were taken: 1)At 0001 on September 15, the Plant Supervisor-Nuclear (PSN}counseled the RCO and the non-licensed person involved in the event regarding the restrictions on manipulating controls.2)The PSN discussed manipulation of controls by a non-licensed person and the requirements.

of 10CFR50.54(i) and 10CFR55.3,at the shift turnover meeting.The Operations Superintendent decided to investigate this event further.Since this event had already been determined not to be reportable under 10CFR50.72 the investigation s purpose was to establish the facts of the event in order to be able to take long term corrective actions to preclude recurrence.

The investigation did not start until September 21, as the Operations Supervisor the, subject RCO, and the Operations Superintendent were offsite on September 15, 16, and 17, and the subject RCO did not report to work on September 18 and 19 due to sickness.On September 22, the Operations Supervisor issued a memo.explaining the requirements of 10CFR50.54(i}

and 10CFR55.3.

All licensed operators have been required to read and sign the memo prior to assuming shift responsibility.

The Quality Assurance Superintendent, upon the request of the Vice President of Turkey Point Nuclear, initiated an independent investigation on September 23.The Uice President of Turkey Point Nu'clear issued a letter to all site personnel on September 24 describing the event and emphasizing compliance with the iegulations.

A second letter was issued on October 2, emphasizing the safety significance of the event.NRC FORM 386A (94)3)

The FPSL commitment tracking system, CTRAC, will be utilized to assure that these reviews will be accomplished.
