EXECUTIVE SUMMARY San Onofre Nuclear Generating Station NRC Inspection Report 50-361; 362/99-301 -

NRC examiners evaluated the competency of four operator license applicants for issuance of operating licenses at the San Onofre Nuclear Generating Station. The licensee developed the retake written examination using NUREG-1021, Interim Revision 8, January 1997. NRC examiners reviewed, and approved the examination. The written examination was administered on April 16,1999, by facility proctors in accordance with the guidance in NUREG-1021, Interim Revision Operations

.

The two reactor operator and two senior operator license applicants passed the examination (Section 04.1).

The test material was adequate for administration as submitted, with no post-examination changes identified (Section 05.1).

04- (Operator Knowledge and Performance 0 Initial Written' Examination i Insoection Scope l On April 16,1999, the' facility licensee proctored the administration of the written -

examination approved by the NRC to the two individuals who had reapplied for a reactor -

operator (RO) and two who had applied for senior operator (SRO) licenses.' The

licensee proposed grades for the written examinations and evaluated the results for question validity and generic weaknesses. The examiner reviewed the licensee's result Observations and Findinas The minimum passing score was 80 percent.- The candidates' scores for the written examination ranged from 88 to 94 percent. The average score was 90. The licensee's post-administration analysis identified that the administered examination was acceptable. There were no post-examination comments or changes to the written

- examination recommended by the licensee or identified by examiner review of the results. Licensee review of the examination results indicated several questions ;

identified potential validity or training deficiencies for further internal review. The l specific questions identified were common RO/SRO questions 1,37,39,52, and 69; RO questions 82,95,~ 96, and 99; and SRO only questions 83,85,86,87,92,96,98, and 99 ,

(shown in Attachment 2 as questions 108,110,111,112,118,123, and 124). The l licensee found all questions appropriate and valid. The examiner reviewed this analysis j and the specific questions and determined that the issues were narrowly focused within j various systems, such as auxiliary feedwater, procedure immediate actions from memory, annunciators, and technical specifications, and did not represent generic weaknesse j ' Conclusions

' The four applicants passed the written' examination. No broad knowledge or training weaknesses were identified as a result of evaluation of the graded examinatio .

.s l-4-05 Operator Training and Qualification 0 Initial Licensina Examination Development The facility licensee developed the initial licensing examination in accordance with guidance provided in NUREG-1021," Operating Licensing Examination Standards,"

Interim Revision 8, dated January 199 .1.1 Examination Outline Insoection Scope The facility licensee submitted the initial examination outlines on January 14,1999. The chief examiner reviewed the subraittal against the requirements of NUREG-1021, Interim Revision . Observations and Findinas The chief examiner determined that the initial examination outlines satisfied NRC requirement Conclusions The licensee submitted an adequate examination outlin . Examination Packaae Insoection Scope The draft examination was transmitted by the licensee to the NRC on March 29,199 The licensee submitted the completed final examination package on April 5,1999. The chief examiner reviewed the examination against the requirements of NUREG-1021, Interim Revision Observations and Findinas The draft written examinations each contained 100 questions. The draft examinations were technically valid, discriminated at the proper 'evel, and responsive to the outline ,

submitted by the licensee. The written examination was considered adequate for administration, as submitted. The examiner developed clarificat, ion or enhancement comments on about one fourth of the questions. The licensee staff incorporated these comments and all proposed enhancements were accepted by the examiner. In contrast to the prior examination (see NRC Inspection Report 50-361; -362/98-302), the submitted examination demonstrated improved question stem focus and distractor credibility. The quality of the submitted examination was reflected in the lack of post-administration changes, especially as compared to the prior examination, for which the license requested changes to a significant number of the questions.
