Dear Mr. Reeq:

. RE:

IMPLEMEUTAnoN OF CATEGORY 2 AND 3 REGULATORY. GUIDES IN THE SYSTEMATIC EVALUATION PROGRAM - DRESDEN UNIT~ l Arm 2 In the Systematic Evaluation Program for your facilities we plan to address_

Regulatory Guides and other staff positions that.have been classified as Category 2 or 3 for implementation by our Regulatory Requirements ~eview Committee.:*

Category 2 and Category 3 are defined as fol rm'ls:.*

Category 2:

Further staff consideration of the need for. backritting appears to be required for certain identified items of the regulatory position -*these individual issues are such that existing plants need to be evaluated to detennine their status with regard to these safety issues.to determine.the need for backfitting.

Category 3:

Clearly *backfit.

Existi11g plants should be evaluated to determine whether identified items of the regulatory position are resolved in accordance with the guide or by some equivalent* alternative *.,,.- *

ENCLOSURE 2 U.S. NUCLEAR REGULATORY COMMISSION REGULATORY GUl'DE Revision 1 November 1976 OFFICE OF STAND.ARDS DEVELOPMENT REGULATORY GUIDE 1.114 GUIDANCE ON BEING OPERATOR AT THE CONTROLS OF A NUCLEAR POWER PLANT A. INTRODUCTION Paragraph (k) of §50.54, "Conditions of Licenses," of iO CFR Part 50, "Licensing of Production and Utilization Facilities," requires that an operator or senior operator licenseq pursuant to IO CFR Part 55, "Operators' Licenses," be present at the controls at all times d*uring the operation of a facility. 1 General Design Criterion 19, "Control Room," of Appendix A, "General Design Criteria for Nuclear Power Plants," to 10 CFR Part 50 requires, in part, that a control room be provided from which actions can be taken to operate the nuclear power unit safely under normal conditions and to maintain the nuclear power plant in a safe condition under accident conditions. As defined in 10 CFR §50.2(t), the term "controls," when used with respect to nuclear reactors, means ap-paratus and mechanisms, the manipulation of which directly affects the reactivity or power level of the reactor. This guide describes a method acceptable to* the NRC staff for complying with the Commission's regulations that require an operator to be present at the controls of a nuclear power plant. The Advisory Committee on Reactor Safeguards has been con-sulted concerning this guide and has concurred in the regulatory position. IB. DISCUSSION Operating experience has shown that there is a need for guidance with regard to acceptable methods of complying with the Commission's requirement for the presence of an operator at the controls of a facility. The operator at the controls of a nuclear power plant has many responsibilities, which include but are not limited to (I) adhering to the plant's technical specifications, plant operating procedures,

  • Line indicates substantive change from previous issue.

' Current *standard Technical Specifications require a licensed operator to be present in the control room at all times while fuel is in* the reactor. USN RC REGULATORY GIJIDES Repulatory Gu1d,es *re' i1sued to d~scribe nnd make 11va1lable 10 the public me~~oas acceo1eble 10 the NRC unff of implementing specific p*ns of tt'le Comm1sa.1on*s regul.!tions, 10 dehneete t*chniQu*s used by the StJff in evalu* ating apecif1c problem& or po11ulattid eccidents. or to provide guidance to 1ppli cants Aeguletory Guidss arQ not substitutas for rogula11ons. *nd compliance with them is not requirad. Mot hods and solutions different from those 1et out in the guides will be acceprnble If th&y provide.o bn&is for the findings requisite to th~ *nuance or continu*nce of o pmrmit or licens.o by the Comm1ss1on. and N RC regulations; (2) reviewing opera.ting data, i"ncluding data logging and review, in order to e:isure safe operation of the plant; and (3) being a~le to manually initiate engineered safety features Ci.Iring various transient and accident conditions. In otder for the operator at the controls of a nuclear power plant to be able to carry out these and other responsibilities in a timely fashion, he must give his attention to the condition of the plant at all ~imes. He must be alert in order to ensure that the p:ant is operating safely and must be capable of taking action to prevent any progress toward a condition that might be unsafe. This is facilitated by control room design and layout in which all controls, instrur.:enta~

  • tion displays, and alarms required for. the safe opera-tion, shutdown, and cool down of the unit are readily available to the operator in the control room.

C. REGULATORY POSITION I. The operator at the controls of a nuclear power plant should have an unobstructed view of and access to the operational control panels, 2 includir:g in-strumentation displays and alarms, in order to be able to initiate prompt corrective action, when neces-sary, on receipt of any indication (instrument move-ment or alarm) of a changing condition.

2. The operator at the controls should not normal-ly leave the area where continuous
  • attc!ltion (including visual surveillance of safety-related annun-ciators and instrumentation) can be given to reactor operating conditions and where he has access to the reactor controls. For example, the operator should not routinely enter areas behind control panels where

' Operational contrpl panels are control panels that en2:-:e the operator at the controls to perform required manual safet~ func* tions and equipment surveillan~ and to monitor plant.:ondi-tions under normal and a.:cident ~onditions.

i.. ' - ' plant performance cannot be monitored. The operator at the controls should not under any cir-cumstances leave the surveillance area defined by regulat0ry position 3 for any nonemergency reason (e.g., to confer with others or for personal reasons) without obtaining a qualified relief operator at the controls. In the event of an emergency affecting the safety of operations, the operator at the controls may momentarily be absent from the defined surveillance area in order to verify the receipt of an annunciator alarm or initiate corrective action, provided he re-mains within the confines of the control room.

3. Administrative procedures should be es-tablished to define and outline (preferably with sketches) specific areas within the control room where the operator at the controls should remain.

The procedures should define the surveillance area and the areas that mav be entered, in the event of an emergency affecting the safety of operations, by the operator at the controls to \\'erify receipt of an annun-ciator alarm or initiate corrective action.

4. Prior to assuming responsibility for being operator at the controls, the relief operator should be properly briefed on the plant status. In order.to en-0 a:

The administrative procedure should include, as a minimum, a definition of proper relief( e.g., what information is* required to be passed on and acknowledged between the two operators).

5. A single operator should not assume the operator-at-the-controls responsibility for two or more nuclear power units at the same time.

D. IMPLEMENTATION The purpose of this section is to provide informa-tion to license applicants and licensees regarding the NRC staffs plans for using this regulatory guide. This guide reflects current NRC staff practice. Therefore, except in those cases in which the appli-cant or licensee proposes an acceptable alternative method for complying with specified portions of the Commission's regulations, the method described hereii'l is being and will continue to be used in the evalua~on of submittals for operating license or con-struction permit applications and the performance of licensees until this guide is revised as a result pf sug-gestions from the public or additio.nal staff review. u
