On April 1,1990, it was determined that control room personnel had failed to complete a Control Element Assembly (CEA) position log as required by Technical $pecifications. CEA positions were required to be determined at least once every 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />, and were obtained from either a printout from the Critical Application Process System (CAPS) computer or by manually viewing the position of each CEA using CEA position indications. The manual means of collecting position data was least preferred but served as a cue since CEA log sheets were provided to the operator. During this event, no log sheet was provided to the control room operator with the result being failure to obtain CEA positions within the required time limit. The root causes for not obtaining CEA position data are surveillance program deficiencies and the lack of management involvement during this time. To ensure the CEA position log is conducted within the required time limit, a procedural change has been incorporated into Unit 2 control room operator's logs requiring verification that CEA position data has been obtained. In parallel, a surveillance testin group has been established to manage the surveillance program. This event has had minimal safety si n1ficance considering that no CEA manipulations were performed nor were any CEA alignment alarms received during the short time interval involved. This event is reportable pursuant to 10CFR50.73(a)(2)(i)(B) as a condition prohibited by Technical Specifications.

A. Plant $tatus At the time this condition was discovered Arkansas Nuclear Of e, Unit Two (ANO 2) was in power  ;

operation at 100 percent. Reactor Coolant $ystem (RCS) [AB) temperatui was 5B0 degrees Fahrenheit and RC$ pressure was approximately 2250 psig.

B. Event Description On April 1,1990, it was determined that control room personnel had failed to complete a Control Element Assembly (CEA) [AA) log in the time period required by Technical Specifications 4.1.3.1.1, 4.1.3.2 and 4.1.3.5. These Technical $pecification sections address asymmetric rod configurations, operability and agreement between corresponding position indicating channels, and the requirement for shutdown CEAs to be in the full out position during plant startup or power operations.

Control room personnel, while obtaining CEA position information on April 1,1990, recognited that they had failed to obtain tha same information during the previous time they were on shif t. A CEA position log used for detection of an asymmetric rod configuration or verification concerning CCA position was required to be conducted at least once during each 12 hour1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> period. Information was typically ;ollected shif tly (once per 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />) for the CEA position log and could be obtained through either a computer printout, from the Critical Application Process Computer System (CAPS),

or through recording CEA positions manually using the applicable log sheet. The log sheet was provided routinely to the operator even though the preferred means of collecting the position data was by obtaining a printout from the CAPS computer. The log sheet, which served 46 a cue (reminder that the surveillance needed to be performed) to the operator, was not provided to the operator by the administrative assistant during this event and is no longer used or provided to the operator for the purpose of recording CEA positions. The administrative assistant withheld the log because CEA position information was routinely collected by CAP $ method.

On March 30, 1990 at 2319, a CEA position log was completed, as required by Technical $pecifications, with the subsequent log conducted on March 31, 1990 at 1520. The time period between these logs was in excess of 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />. Both of the CEA logs taken before and af ter the missed interval met the requirements set forth in the applicable Technical Specifications. During the interval that 1 the CEA position verification was not conducted, no CEA manipulations were performed nor were any CEA deviation alarms received in the control room. Upon discovery of the condition, a verification i 3

was made to confirm that there was only one missed interval and that satisfactory CEA position ,

information had been obtained prior to the time the log should have been performed.  !

C. Root Cause The root causes for not performing the CEA position verification in accordance with Technical

$pecifications are program deficiencies within the surveillarce program, and the lack of management involvement during this time. During this period, the surveillance program did not ensure that j cues were provided for all surveillances to ensure their initiation and completion. Additionally,  !

ownership of the surveillance program was fragmented with no single manager responsible for the program.  ;

D. Corrective Actions i

Operations management has communicated this event during respective shift turnovers to all Unit 2 Operations personnel emphasizing the importance of ensuring that surveillances are controlled and completed as required. This has been done initially during shif t turnover and will be reemphasized during operator requalification. The shift briefing has been completed with the requalification presentation to be completed before June 30, 1990.

To ensure the CEA position data is obtained shif tly, a procedure change has been incorporated into Unit 2 control room operator's logs requiring shiftly documented verification that the CEA position log has been performed. This check off requirement on the control room operator's log cues the operator to perform the CEA position log and has been implemented in Unit 2 control room. A revision to Unit I logs will be implemented prior to May 15, 1990. In addition, a review has been implemented to identify and correct any surveillance that does not have an adequate cue j including conditional (event

• initiated) and Technical Specification required surveillances. Cue related corrective action will become effective prior to May 15, 1990.

To address the problem concerning a lack of ownership for the surveillance program, in parallel with this event, a surveillance testing group has been established to manage the AND $urveillance Program. This group has responsibility to review any changes associated with the surveillance program, communicate management expectations concerning the importance of the surveillance program, review and revise surveillance program administrative procedures as necessary to ensure that adequate program atic controls are in place, and review changes that effect procedures identified on the Master Test Control List. These program changes will be in effect by July 1,1992.

The programmatic changes which are currently in place or will be implemented in the future to ensure additional surveillance intervals are not missed were presented during the Arkansas Nuclear One quarterly Performance Meeting on April 24, 1990, to NRC Region IV and NRR representatives.

E. Safety Significance CIA positions were verified to be in conformance with Technical $pecification requirements shortly af ter the time limit for performing the CIA position verification had expired. The failure to perform the CEA position log during the required time period had minimum safety significance considering that no CEA manipulations were performed nor were any CCA misalignment alarms received during the time interval involved.

F. Basis for Reportability This event is reportable pursuant to 10CFR50.73(a)(2)(i)(B) as a condition prohibited by Technical Specifications G. Additional Information

$1milar events involving failure to perform e Technical Specification surveillance within the required surveillance interval were reported in LtRs 50 368/88 017-00, 60-368/89 002 00, 50 368/89 010-00, and 50 368/90 003 00.
