3-EXECUTIVE SUMMARY l
South Texas Project Electric Generating Station, Units 1 and 2_
NRC Inspection Report 50-498/97-301; 50-499/97 301
- NRC examiners evaluated the competency of 6 reactor operator and 8 senior operator applicants for issuance of operating licenses at the South Texas Project facility.' The licensee developed the initial license examinations using NUREG-1021, " Operator Licensing Examination .
Standards for Power Reactors," Interim Revision 8. NRC examiners reviewed, approved, and administered the examinations, The initial written examinations were administered to all 14 applicants on October 17,1997, by facihty proctors in accordance with instructions provided by the chief examiner. The NRC examiners administered the operating tests on December 1-5,199 Ooerations
- All six applicants for reactor operator licenses and all eight applicants for senior operator licenses displayed the requisite knowledge and skills to satisfy the requirements of 10 CFR Part 55 and were issued the appropriate licenses (Sections 04.1,04.2).
'
. Overall, the operator license applicants demonstrated good crew dynamics and communications. Individual self verification was consistently good during control panel and equipment manipulations (Section 04.2).
- The licensee initially failed to submit an acceptable examination for administration to operator license applicants for the control room systems and facility walkthrough portion of the examination. Several revisions by the licensee were required to produce a product which satisfied examination standards. This resulted in delaying administration of the operating test portion of the examination (Section 05.1).
- A violation involving the granting of examination exemptions to two individuals, contrary to the regulations, was identified by the NRC. Because the licensee had completed itt assessment and revised its procedure to prohibit exemptions and ensure that all licensed operators meet the requirements, no response was requested (Section 08.1).

L_Q9ffADDL 04 Operator Knowledge and Performance 0 Initial Written Examination l_nsocction Scong On October 17,1997, the licensee proctored the administration of the written examination approved by the NRC to six individuals who had applied for initial reactor operator licenses and eight individuals who had applied for initial senior operator licenses. The licensee graded the written examinations and its staff reviewed the result The licensee also performed a post-examination question analysis, which was reviewed by the examiner Observations and Findinos The minimum passing score was 80 percent. All applicants for reactor operator licenses passed with scores langing from 81 to 91 percent. All appi; cants for senior operator licenses passed with scores ranging from 81.8 to 94.9 percent. The average score for reactor operator applicants was 86.8 percent and the average score for senior operator applicants was 88.9 percen The above grades reflected the results after examination changes recommended by the
- licensee as a result of post-examination question analysis were incorporated. The examiners reviewed and ac;epted these recommendations based on the technical merits of each recommendation. As a result of this analysis, two answers were accepted for Questions 54 and 59, which were common te both examinations. Also, two answers were accepted for Question 95 on the reactor operator examination. Question 15 on the senior operator examination had no correct answer and was delete The chief examiner reviewed the licensee's question analysis with particular attention to those questions which were missed by more than half the applicants. Only questions 86 and 96, which were common to both examinations, were in that category. Reasons for missed questions appeared related to isolated training weaknesses. The chief examiner determined that there were no significant interrelationships to indicate genenc weaknesses in knowledge or abilit .
.
5 Conclusions All applicants passed the written examinatio '04.2 initial Ooeratina Test Insoection Scope The examination team administe ed the various portiorss of the operating test to the 14 applicants on December 14,1997. Each applicant oarticipated in one to three dynamic simulator scenarios. Each also received a walkthrough test which consisted of ten system tasks tog " er with two followup questions for each system, except for four applicants who were upgrading their reactor operator to senior operator licenses and were each administered five system tasks with followup questions. Five subjects in four administrative areas were covered by administrative tasks for all applicant Observations and Findinos All applicants passed all sections of the operating test. Generally good crew dynamics and ,ommunications were observed. One exception was noted during one scenario when confusion arose concerning the implications of certain plant indications. The panel operators became very concerned about their individual panel indications and manipulations and declined to support periodic briefings by the control room superviso Also, because of their preoccupation with their panels, the supervisor had to repeat several of his directives. The examiners obscrved good plant awareness, ownership, and application of principles for self-verification of individual performance by the applicants throughout the examination. The application of management expectations for peer checking by the applicants ranged from outstanding to nonexistent, depending on the crew being observe Conclusions All aoplicants passed all sections of the operating test. Overall, the operator license apphcants demonstrated good crew dynamics and communications. Individual self-verification was consistently good during control panel and equipment manipulation Operator Training and Qualification 05.1 initial Licensina Examination Develooment The licensee developed the initial licensing examination in accordance with guidance provided ir NUREG-1021.

,
a- Insoection Scooe The licensee submitted the initial examination outline on August 19,1997. The examiners reviewed the submittal against the requirements of NUREG-102 Observations and Findinos -
The chief examiner provided several enhancement suggestions related to examination integrity and responsiveness to NUREG 1021 requirements, which were incorporated by the licensee in the written examination outline. There appeared to be excessive day to-day overlap of subject material on the administrative portion of the examination The final outlines included more differences in subject matter from day-to-day. Also, unique discriminatory tasks were developed in several instances in which the same subjects were covered from day-to-da The licensee incorporated a number of enhancement suggestions for the walkthrough task outline. Several of the changes related to providing the recommended coverage of safety functions, engineered safety features, and radiological controlled area entr Other comments related to expected examination difficulty and administration efficienc The licensee acknowledged these comments for consideration in developing the final test item Also, the licensce incorporated a number of enhancement suggestions for the dynamic scenario outline.' The licensee did not have a clear understanding of what constituted a normal event for examination purposes. It subsequently replaced some events to clearly satisfy NUREG 102 After consideration of NRC comments on both the original outline and test items, the licensee submitted an acceptable final outline on October 29,199 Conclusions
- After incorporation of several enhancement suggestions provided by the examiners, the
- licensee submitted an acceptable final outline.

chief examiner reviewed the submittal ag& inst the requirements of NUREG-102 ;
' Because of extensive NRC comments on the initial submittal, the licensee submitted a
. revised operating test package on October 29,1997dollowing onsite review by
. examiners during the week of October 20,1997,
, Observations and Findings ,
,
The licensee submitted 124 draft written examination questions, of which 76 were designated to be common to both the reactor operator and senior operator examination The licensee subsequently submitted an additional question during the initial review to satisfy the NUREG-1021 requirement for having 25 unique questions on the senior
- operator examination. The chief examiner provided comments or questions on'15
- questions on the reactor operator examination and 10 questions on the senior operator .
examination, In resolving these questions and comments, the licensee modified or replaced 7 questions which were common to both examinations,4 questions which appeared only on the reactor operator examination, and 3 questions which appeared only on the senior operator examinatiort Additionally, as a result of further internal review, the licensee modified or replaced 5 questions common to both examinations,
!
3 questions which appeared only on the reactor operator examination, and 1 question '
which appeared only on the senior operator examination. As discussed ;n Section O4.1, following post-examination review, credit was given for two answers for 3 questions on the reactor operator examination and 2 questions on the senior operatoi examination in addition,1 question, which had no correct answer, was deleted on the senior operator examination. Although failure to make the above changes would not have invalidated the examinations, it would have seriously degraded their discriminatory value. The examinations were considered marginally adequate for administration as submitted,
^
based on the pre- and post-examination change The hcensee submitted six dynamic scenarios, including one backup scenario, which was not used during the examination. The submitted scenarios were adequate for administration. Howevet, the expected operator action forms did not meet the quality
,
requirements discussed in NUREG-1021. Also, the quality assurance forms did not accurately reflect what was included in the scenarios in all instances. The licensee
- subsequently incorporated several enhancemer,t suggestions provided by the NRC examiners as a result of a table top review and onsite evaluatio The licensee submitted four sets of job performance measures to cover the
? administrative section of the examination. One set was designed for the reactor operator
'
- applicants and three sets were designed for senior operat_or applicants. Although some of the attachments were not included in the initial submittal, the job performance

8-measures were adequate for administration with suitable attachments. The licensee provided the proper attachments and incorporated several chief examiner enhancement suggestions in the as-given administrative section of the examination To support the control room systems and facility walkthrough section of the operating test, the licensee provided 25 job performance measures developed to evaluate selected operator tasks. They were arranged in four sets to administer to the various spplicant There was no day-to-day overlap of specific tcsks in the sets. Although individual job performance measures were generally acceptable for administration as submitted, the combinations identified for individual sets did not discriminate at the required level for certain groups of applicants. For example, one set of five job perfonnance measures for two upgrade applicants contained only one .iob performance measure that had more than minimal discriminatory value and one was considered too simple in that it only required the applicant to identify the failure position of three valves on a drawing for a passing grad Similarly, the facility walkthrough subsection of the examination for all the instant senior operator and reactcr operator applicants did not discriminate at the required levelin that only one of the job performance measures displayed more than minimal discriminatory value and one was considered too simple in that the only action required for a satisfactory grade was to reset the mechanical overspeed trip device on the turbine driven auxiliary feedwater pump. Although this is an important action, it was difficult to demonstrate that the required skill would be discriminator As a result of the above comments, the licensee resubmitted the walkthrough job performance measures prior to an onsite review by NRC examiners. The resubmitted job performance measures were acceptable for administration. Also, the licensee incorporated several examiner suggestions to enhance the overall quality of the examination. For example, after reconsideration, the examiners determined that an additional job performance measure was too simple, in that, it required manipulation of only one component. The licensee replaced it with a more complex task. Also, an appropriate starting point was not identified for a job performance measure and procedure ana job performance measure performance steps were in conflict. The licensee made appropriate changes to that job performance measur The licensee was also required to submit 2 or more followup questions associated with each walkthrough task. Only 1 followup question was provided for four of the tasks in the initial submittal For some tasks,3 questions were submitted without instructions on how they were to be used. The licensee failed to follow guidance provided in NUREG-1021, Appendix C, Section 6, for construction of the followup questions. The majordy of the questions were considered direct lookup, which are to be avoided in accordance with Appendix C. Also, most of the questions testeo at the memorization and recalllevel, which is disecuraged in Appendix C. Overall, the task followup questions did not discnminate at a high enough level and were considered inadequate for administratio In response to the above comments, the licensee resubmitted the followup question . _

The chief examiner noted improvement in question quality. However, more information was required on a significant number of the 50 questions to allow the chief examiner to venfy that the provided solutions were correct. Three of the questions did not satisfy the I
guidelines in the examiner standards and were rewritten or replaced. Also,2 other
- questions wete deemed to have been adequately covered in other parts of the examination and were replaced by the license l The job performance measure followup questions were resubmitted by the licensee a
- second time as a result of the further comments. The operations branch chief and chief examiner determined that 0 of the resubmitted questions could be considered direct lookup. Also, the region provided comments on question construction or outline
~ descriptions for 11 other questions. In addition, the licensee rewrote 1 closed reference
. question as an open-reference question to increase the percentage of open-reference questions on the examinations for certain applicants. The licensee made appropriate revisions to the followup questions to address the above comments and the examiners considered the final product acceptable, The number of iterations required for the licensee to upgrade the systems and facility walkthrough part of the examination to satisfy NUREG-1021 requirements resulted in delaying the administration of the operating test part of the examination from October 20 to Det, amber 1,1997, Conclusions The licensee initially failed to submit an acceptable examination for administration to -
operator license applicants for the control room systems and facility walkthrough part of the examination. Several revisions were required by the licensee to produce a product which satisfied examiner standards. . This resulted in delaying administration of the operating test part of the examiaatio .2 Simulation Facility Performance Ingoection Scoce

Several problems with rod control and position indication systems were noteworthy because similar problems have occurred during previous examinations at this facility, Conclusions The simulation facility supported examination administration well. Recurring problems with rod control and position indicating systems had minor effects on examination administration and validatio .3 bamination Securily r Scope The examiners ieviewed examination secunty both during onsite preparation week and examination administration week for compliance with NUREG-1021 requirement Observations and Findirios During onsite preparation during the week of October 20.1997, the examiners observed that examination security was generally good. However, some of the controls t. vere not clearly defined. In one instance an individual not on the examination security agreement walked through two doors posted "Do Not Enter" to enter the simulator instructor booth during the examination validation activities. He was challenged after a few seconds and placed on the examination security agreement. No examination compromise occurre Pnor to examination administration week, new locksets were installed on all doors leading to the simulator, Keys for these locksets were controlled by the simulator support cupervisor and security and issued only to personnel on the security agreemen Also, yellow arm bands with the words "NRC EXAM TEAM" were issued to examination team members to make it clear who was authorized to be in the examination area. This system worked wel Conclusions After a potential examination compromise incident during the onsite examination preparation week, the licensee implemented an examination security plan which was effectiv . _ - - . - - -- .. - - - . .

1994 or early 1995. The licensee also confirmed that no licensed personnel actively performing licensed duties had been granted an exemption and that only two licensed, but inactive, operators had been granted this exemption. The licensee had revised the procedure to remove the exemption and ensured that all licensed operators met the requirements of 10 CFR 55.59(c)(4). However, for the period of October 31,1994 until August 12,1997, the licensee had granted two individuals examination exemptions .
