1.0 INTRODUCTION

The NBSR operator requalification program is designed to provide refresher training to the licensed operator in areas of infrequent operation, to review facility and procedural changes, to address subject manner not reinforced by direct use, and to improve in areas of performance weakness. The program is designed to evaluate an operator's knowledge and proficiency to perform their duties and to retrain where necessary. Emphasis is placed on those subjects necessary for the continued proficiency. Successful completion of the program is required for the operator to continue licensed activities. The program conforms to the applicable content of ANSI/ANS-15.4-2007,. "ý:Selection and Training of Personnel for Research Reactors."

shall, should, and may. The word "shall" is used to denote a requirement; the word "should" to denote a recommendation; and the word "may" to denote permission, neither a requirement nor a recommendation.

3.0 GENERAL 3.1 Administration. Responsibility for the administration of therequalification program rests with the Chief, Reactor Operations. The program shall be administered over a period not to exceed 24 months, followed by successive 24 month periods. '.

3.2 Description. During the requalification period/,the following shall be provided or accomplished:

(a) Refresher training (b) Written examination (c) Medical evaluation .

(d) Reactivity manipulations (e) Operating test or evaluation .

(f) Document Review

\-

3.2.1 Refresher Training. This training shall beýprovided in critical areas not routinely used by the operator such as emergency planning, response to abnormal conditions, selected topics in radiationprotection and reactor operation principles, and changes to facility design and procedures..

3.2.2 Written Examination. Written examinations shall be operationally oriented, practical, "and objective. The interval between> any two successive exams shall not exceed 30

'moniths. The numb&and form ~ofquestions shall be selected to best evaluate a particular examinee, but the number of 4uestions successfully answered shall not preclude attainmenit- of the minimum acceptance score specified in section 3.2.2. 1. The exam should be,of a multiple choice type, composed of multiple categories, with 20 questions per categoryz'andwith four answers per question. The following categories should comprise the exam':

(a) Theory. Topics include nuclear theory, principles of reactor operations, general and specific facility operating characteristics, and applicable -thermodynamics.

(b) Procedures and Radiological Controls. Topics include normal procedures, abnormal procedures, emergency procedures, radiation protection principles and procedures, administrative rules, and technical specifications.

(c) Systems. Topics include plant systems, radiation protection systems, instrumentation and controls, and facility protection and engineered safety features.

2

3.2.2.1 Examination Administration and Evaluation. The minimum acceptance score shall be 70% for each category of the written examination. Individuals who did not achieve passing scores in one or more of the categories listed in section 3.2.2 may be re-examined following retraining in the deficient areas. The Chief, Reactor Operations may waive re-examination in categories with passing scores providing the candidate has demonstrated proficiency in those portions of an examination.

3.2.2.2 Evaluation and Retraining. Additional requalification training in the form of formal lectures, tutoring, self-study or on-the-job training shall be based on the results of the requalification examination. The foll0oing considerations should be used:

(a) A score on the written examination equalt60or greater than the acceptance criterion may require no additional training.'

(b) A score on the written examination belw bthe acceptanrcecriteria in section 3.2.2.1 shall require additional training in hose topics where weakness or deficiencies are indicated. This'retraining and retesting shall be completed prior to the candidate being relicerised.

(c) An overall score on the written examinatioh, of less than 60%?shall require that an evaluation by Chief, Reactor Operations or designated representative be performed. Thelevaluation shall determine if the deficiencies require that the individual's license be withdrawn pending:'completion of an accelerated retraining effort. The evaluation, shall take intoaccount the individual's past performance record, supervisor' s evaluation and/ past test scores, as well as current deficiencies. Additionaloral or operational examinations may also be givenito'oidin the evaluati6n. In any case, the individual shall be removed from licensed activities within four months if the candidate cannot

,achieve passing scores after re-examination.

(d) Regcadless ofthe, score, if the evaluation indicates a deficiency in a critical area that affects sa*ety, training shall be administered to promptly correct the- criticl, 6dficiency. .'

3.2.3 /Medical Examination.,, Eacli~lic`nsed individual shall undergo medical examination and evaluation se t 63-. as 3.1. part Th, o fthe requalification V

2 .. program and shall meet the requirements r of sectiqn 3.2.3.1. The primary responsibility for assuring that qualified personnel are on-duty rests with the Chief, Reactor Operations. The health requirements set forth herein shall be considered to determine the physical condition and general health of the individual in 6rder-to perform certain assigned duties as determined by the Chief, Reactor Operations. Each requirement should be considered in the context of the certain assigned duties of the individual as related to the consequences of health-induced operational errors endangering public health and safety. The designated medical examiner shall be conversant with the requirements.

The interval between any two successive medical evaluations shall not exceed 30 months.

More frequent examinations may be required if conditions warrant as determined by the Chief, Reactor Operations or upon the recommendation of the designated medical examiner. The physical condition and the general health of an operator shall be such that 3

they are capable of properly carrying out licensed activities under normal, abnormal and emergency conditions and able to perform the associated tasks. Conditions that can cause sudden incapacitation such as coronary heart disease, stroke, epilepsy, mental disorder, diabetes, fainting spells, impaired hearing or vision, and effects of medication, shall be considered. Many of the conditions indicated above may be accommodated by restricting the activities of the individual, requiring close surveillance of the condition, imposing a medical regime, or requiring a second individual to be present when the individual' in question is performing certain assigned duties. As a minimum, the second individual shall be able to shut down the reactor and summon competent help.

(3) Maintenance and monitoring tasks including verifying operability of equipment for the purpose of techiicall'specification'compliance, routine inspection of the facility, surveillance'tests, water chemistry analysis, and demonstrating knowledge of reactor system and auxiliary systems' controls and indications,"--\

(b) Abnormal Circumstances (1) Response to alarms and trips such as scrams, rundowns, high radiation, low water level,.loss of coolant, loss-of flow, and loss of electrical power.
