DESCRIPTION OF THE GPU LONG-TERM STA PROGRAM The GPU STA program is described in the following enclosures: - Position Description - Qualifications of the Shif t Technical Advisor - Education and Training Requirements.
Since the selection and training of STA's for the GPU progran began prior to the issuance of the INPO document, " Nuclear Power Plant Shif t Technical Advisor - Recommendations for Position Description, Qualifications, Education and Training" (Revisica 0, April 30,1980), some of the requirements of our program differ from the INP0 program, although we feel that we meet the intent of the program recommended by INPO.
Specific comparison to the INP0 document is made only in the education and training section since some portions of this section are still being developed for our program.

ENCLOSURE 1 POSITION DESCRIPTION Position: Shift Technical Advisor Reoorts to: Plant Analysis Manager Accountability Obj ective:
The Shift Technical Advisor will be responsible for advising the shift super-visor on technical questions and for monitoring operation to ensure safe, reliable and efficient performance. The STA will evaluate the technical performance of the reactor plant during power, startup, shutdown and refueling modes as well as periods of cold shutdown when special maintenance evolutions or tests are in progress.
The STA will be available to advise the on-shift operation supervisor of the actions necessary to maintain or regain a safe, stable operating state.
, The major function of this position is to make additional engineering and technical expertise available to the shift operations staff. The STA will perform the functions of the position independent of.he operations shift organization. The STA will not displace any of the present functions of the shif t organization but rather supplements the capability of the shif t to operate the plant safely and reliably. A secondary function is to assist in maintaining and improving plant satety by evaluating plant performance and provide effective feedback to Technical Functions.
Dimensions This position contributes to the safe, reliable and efficient operations of nuclear gener'ating stations with a value of $500 MM.
Nature and Scope Six Shift Technical Advisors from each nuclear generating station report to the Plant Analysis Manager along with three STA trainees from each station, two Plant Analysis Engineers from each station and-five Plant Analysis Engineers at headquarters.
' The STA will monitor the response of the plant during transients and accidents, determine if the plant is responding within safety limits and advise the shift supervisor of abnormal _ status. and the corrective actions needed to prevent adverse consequences.
The STA will monitor the technical performance of the plant during steady state operation and during planned evolutions such as startup, shutdown and power changea. The STA will monitor the trends of critical-parameters to determine if the plant is operating within design limits. The STA will review and eval-uate all operations conducted during the shif t that could jeapordize the safe operation of the plant.

2 The STA will advise the Shift Supervisor immediately of any reco=mendations or evaluations during the shift and will keep the Plant Analysis Manager apprised of abnormal plant conditions in a timely manner appropriate to the condition but not to interfere with the safe operation of the plant.
The STA will monitor the readiness of the Plant Protection Systems, i.e., the RPS, ECCS, ESFAS, to perform their design function and be especially alert to testing or maintenance evolutions that could prevent these systems from perfo rming.
The STA will make a technical evaluation of all significant events that occur during the shift. The object of this evaluation will be to determine the cause of the event and determine the corrective actions necessary to prevent re-occurrence.
The STA will periodically monitor selected plant evolutions and surveillance tests to evaluate the effectiveness of plant procedures.
The STA will be aware of significant operating events that occur at other nuclear power plants and the potential applicability of those events to the operation of the plant.
The STA will review TCN's and Special Operating Procedures that are implemented before receiving normal Technical Functions review for technical adequacy and safety considerations.
8 The STA will perform a shif t relief af ter each shif t effectively communicating a complete plant status to the oncoming STA.
Prior to assuming the responsibilities of this position, each individual vill be required to complete a training program and be certified by written and oral examination to meet the qualitications stated in Attachment A.
After initial certification, each STA will be required to participate in a training program and fulfill the requirements for obtaining an NRC Senior Reactor Operator's License. After obtaining a license status each STA will participate in training programs to maintain licensability and to increase their proficiency as STA's.
This position performs its responsibilities on rotating shifts on the site of the nuclear generating station either in the control room or in the plant within ready access to the control room.
Principal Accountabilities 1.
Monitor and evaluate the performance of the plant during steady state operation, planned evolutions, transients and accidents.
2.
Advise the Shift Supervisor of abnormal conditions and of corrective actions needed to prevent adverse consequences.
3.
