05 Operator Training and Qualification 05.1 General Comments Operator initiallicensing examinations were administered at the Prairie Island Nuclear Plant to four Senior Reactor Operator (SRO) applicants during the week of June 16,199 The initial operator licenso examinations woro developed by the licensee in accordance with guidance prescribed in NUREG 1021, * Operator Licensing Examiner Standards," Revision 7, and as noted in NRC Generic Letter 95 06,
" Changes in the Operator Licensing Program," August 15,1995. The NRC reviewed and approved the proposed examination material prior to administration by liennsing examinors, with one exception. The NRC allowed the licensoo staff to administer the written portion of the examination without NRC presenc The licenseo developed examination material was submitted to the NRC in a timely manner and ahead of the scheduled deadlino as specified in NRC Gl. 95 06. The NRC review determined that the outline and the written and operating examination material met the requiromonts as specified in NRC GL 95 06. However, the quality and lovel of difficulty of the written examination questions required substantial revision to ensure consistency with previously administered examinations. (See Section 05.2).
05.2 Examination Premation and Validation Examination Scong Examination guidance contained in NUREG 1021, Revision 7, and NRC Generic Letter 95-06 was mado available to the licenseo for the development of the written and operating examination material. The examiners were able to review, reviso, and validate the written and operating examination material during the week of June 2,1997. The validation process involved the verification of licenseo administrative and operating procedures to ensure that exam validity and content were consist with operations expectations, Observations and Findinna The review and verification of the examination outline and examination material was f acilitated by early submittal of the required material and by the level of detail contained in the proposed examination nateria The operating examination consisted of an administrative section, a job performance measure (JPM) walkthrough section, and an operating (dynamic scenario set) section. The operating examination contained a mixed level of quality and difficulty. The dynamic scenario set was well structured and contained all of the necessary elements to evaluate the applicants at the senior operator level. Both sconarios required very little revision prior to administration. The watkthrough JPMs were appropriately structured but contained some elements that needed clarification or some elements that were omitted. Ono JPM required replacement

while some other JPMs required a mixed level of revision. The administrative tasks were appropriate for the senior operator position and required little chang The written examination contained 100 multiple choice questions and was evaluated as meeting the standard as outlined in NUREG 1021, Revision However, selected questions varied widely in quality and difficulty from straight memory to comprehension / analysis. The quality and difficulty of the overall examination was marginal as compared to previously administered examinations and required significant improvement. The licensee revised the examination and
- with NRC oversight was able to develop a high quality examination. The overall difficulty was raised to an acceptable level as indicated by an average score of 84.25E The examiners were afforded the appropriate level of assistance and access to the plant specific simulator during setup and validation of the operating examination in accordance with ES 301 of NUREG 1021. A high level of examination security was maintained during this validation process. Additionally, a portion of the walkthrough JPMs were validated using the site facility. The licensee's assistance during the examination review and validation process provided the NRC examiners with appropriate operational expertise and clarification in technical matters.- The written and operating examinations were verified to be valid for the tasks and conditions specified, Conclusions The dynamic simulator examination was well structured and of the appropriate difficulty level. The job performance measures were of the appropriata difficulty ;
level but did require some clarification or some additional information. The administrative section was appropriat l The written examination was of marginal quality and required significant revision by the NR The licensee demonstrated good support to the examination process by maintaining a high level of examination security and early and complete submittal of l examination materials.
l 05.3 Examination Administration i Ex6mination Scong The written examination was administered on June 16,1997, by the licensee's training staff with approval from the NRC. The examiners administered the operating examination between June 17 19,1997, to four applicants using guidance provided in NUREG 1021i Revision 7. The operational examination , involved extensive use of the plant specific simulator during dynamic scenario sets and control room job performance tasks. Additional testing was conducted at the site facility.

,. ., l QhtflyAllens and Find;not r The applicants demonstrated satisfactory knowledge and skills in handling the assigned operational tasks required during normal and abnortnal evolutions. All of j the applicants demonstrated a weakness in their communication skills as demonstrated during the dynamic scenarios. A comnion problem was improper or l incomplete repeat backs and inconsistent acknowledgements to reports (i.e. "Yes' or " Understand *).
- ,
I Additionally, the following individual weaknesses were noted during the operating examination:
* Procedural guidance usaga during JPMs was not consistent with licensee expectations. More than one applicant either overlooked a step or performed an evolution on the wrong equipmen * JPM follow up questions identified a lack of understanding of a recent modification to the auxiliary feedwater motor-driven pump trip circuit, + JPM follow up questions idantified a lack of understanding of the effect that a loss of Bus 111 instrument power would have on the RHR system.
' The following common weaknesses were noted on the written examination:
* Knowledge of the electrical power supply to the charging pumps when cross tie * Ability to operate or verify proper operation of the auxiliary feedwater system following an anticipated transient without scram conditio * Knowledge of the process for removing decay heat from the core upon entry into function recovery procedure * Abill.y to perform without reference the immediate operator actions required for a loss of component coolin * Ability to d,termine the required core exit temperature that must exist followir.g a reactor coolant system cooldown in response to a steam generator tube rupture event.
' These deficiencies are provided as feedback to the licensee's systems approach to training process. No response is required, c. Conclusions Overall, the operator performance demonstrated during the operating examination was appropriate to ensure safe reactor operations. All of the applicants demonstrated appropriate skills required to handle any operational task. Even though poor use of repeat backs and other performance weaknesses were noted, the NRC examiners concluded that no programmatic deficiency was indicate _ . - _ . _ _ . . _ . - .- _ _ _ - _ . _ - . _ _ _ , _ - . _ . _ _ _ _ _ . . _ .
