REACTOR LICENSEES SUBJECT: FIVE ADDITIONAL

TMI-2 RELATED REQUIREMENTS

TO OPERATING

REACTORS Gentlemen:

Over the past few months, the NRC has been developing its requirements that flow from various reviews following the TMI accident of March 28, 1979.All TMI-related issues are being included in the NRC's TMI Action Plan.On September

13, 1979, you were informed of the first set of TMI-related actions based upon Lessons Learned that were required for operating reactors.On February 8, 1980, the Commission preliminarily approved the Near-Term Operating License requirements of the TMI Action Plan. There are five items that are applicable to operating reactors and constitute a second set of requirements for operating reactors.

They are as follows: (1) I.A.1.3-Shift Manning; (2) I.A.3.1 -Licensing Examinations:

(3) I.C.5 -Licensee Dissemination of Operating Experiences;

(4) II.K.3 -LOFW and Small Break LOCA Generic Review Matters; and (5) III.D.3.4

-Control Room Habitability.

These matters are specified in the Task Action Plan (NUREG 0660, May 1980).Items 1, 2, 3 and 5 involve actions for all reactor plants whereas item 4 concerns only specific light water reactor types. Item 4 involves 28 separate actions; i.e., 15 for BWR plants (including

1 for Big Rock); 7 for PWR plants (including

3 for Westinghouse designs);

and 6 for all light water reactor plants. Five of the items are applicable to Fort St. Vrain.Requirements for the implementation of each of these actions are provided in this letter, except for items (1) and (2). Item (1) will be provided shortly through separate correspondence and Item (2) was provided to you by letter dated March 28, 1980.The implementation schedule for the five action items as they apply to the various operating reactor designs is given in Enclosure

(1). Enclosure (2); (3) and (4) are specific with regard to the three remaining items as they apply to any specific plant design. Each enclosure consists of two parts; i.e., the first part is the staff requirement and the second part is a copy of the applicable section of the plan. The NUREG reports referenced in these enclosures will be provided to you shortly through separate correspondence.

g0 06 9 /667

-2-I;.Each of the specific actions includes an implementation schedule as to how and when the particular action is to be carried out. Three classes are indicated;

i.e., Class 1 involves no hardware changes and requires that the action is to be implemented by the specified date; Class 2 involves possible hardware changes that may be effected without prior staff review;and Class 3 involves hardware changes that would be made subsequent to staff revfiew and approval.You are requested to reply within 30 days stating your commitment to meet these requirements and associated schedules.

EXPERIENCE

TO PLANT STAFF PART 1: Staff Requirements I.C.S'PART 2: Copy of Section I.C. to NRC Task Action Plan

• l.C.5 PROCEDURES

FOR FEEDBACK OF OPERATING

EXPERIENCE

TO PLANT STAFF POSITION In accordance with Task Action Plan I.C.5, Procedures for Feedback of Operating Experience to Plant Staff, each licensee shall review its procedures and revise them as necessary to assure that operating infor-mation pertinent to plant safety originating both within and outside the utility organization is continually supplied to operators and other personnel and is incorporated into training and retraining programs.These procedures shall: (1) Clearly identify organizational responsibilities for review of operating experience, the feedback of pertinent informa-tion to operators and other personnel and the incorporation of such information into training and retraining programs;(2) Identify the administrative and technical review steps necessary in translating recommendations by the operating ex-perience assessment group into plant actions (e.g.> changes to procedures;

operating orders);(3) Identify the recipients of various categories of information from operating experience (e.g., Supervisory personnel, STA's, operators, maintenance personnel, H. P. technicians)

or other-wise provide means through which such information can be readily related to the job functions of the recipients.

(4) Provide means to assure that affected personnel become aware of and understand information of sufficient importance that should not wait for emphasis through routine training and re-training programs;(5) Assure that plant personnel do not routinely receive extraneous and unimportant information on operaTing experience in such volume that it would obscure priority information or otherwise detract from overall Job performance and proficiency;

(6.) Provide suitable checks to assure that conflicting or contradictory information is not conveyed to operators and other personnel until resolution is reached; and, (7) Provide periodic internal audit to assure that the feedback program functions effectively at all levels.DISCUSSION

Each utility is expected to carry out an operating experience assessment function which will involve utility personnel having collective competence in all areas important to plant safety. In connection with this assessment function it is important that procedures exist to assure that important

-2 -information on operating experience originating both within and outside the organization is continually provided to operators and other personnel and that it is incorporated into plant operating procedures, and training and retraining programs.Those involved in the assessment of operating experience will review in-formation from a variety of sources. These include operating information from the licensee's own plant(s), publications such as IE Bulletins, Circulars and Notices, and pertinent NRC or industrial assessments of operating experience.

In some cases, information may be of sufficient importance that it must be dealt with promptly (through instructions, changes to operating and emergency procedures, issuance of special precautions, etc.) and must be handled in such a manner to assure that operations management personnel would be directly involved in the process.In many other cases, however, important information will become available which should be brought to the attention of operators and other personnel for their general information to assure continued safe plant operation.

Since the total volume of information handled by the assessment group may be large it is important that assurance be provided -that high-priority matters are dealt with promptly and that discrimination is used in the feedback of other information so that personnel are not deluged with unimportant and extraneous information to the detriment of their overall proficiency.

It is Important, also, that technical reviews be conducted to preclude premature dissemination of conflicting or contradictory infor-mation.CLARIFICATION

Review of and modifications to procedures governing feedback of operating experience to plant staff shall be completed and the procedures put into effect on or before January 1, 1981.ACTION: (Class I)(1) Licensee to implement actions and submit documentation of the method for staff review by scheduled dates.

The following thirteen pages are from the May 1980 version of the TMI Action Plan, NUREG 0660,Section I.C.This section is provided for background information only and to note that the subject item being discussed with respect to our position on I.C.5. is a-subpart.

Task I.C May 1980 TASK I.C OPERATING

PROCEDURES

A. OBJECTIVE:

Improve the quality of procedures to provide greater assurance that operator and staff actions are technically correct, explicit and easily understood for normal, transient, and accident conditions.

The overall content, wording, and format of procedures that affect plant operation, administration, maintenance, testing, and surveillance will be included.

A principal part of this work is to improve procedures for dealing with abnormal conditions and emergencies by improving the delineation of symptoms, events, and plant condi-tions that identify emergency or off-normal situations that confront the operators and, once identified, to assure consistency with operator training.B. NRC ACTIONS: NRC has taken action, and will take further action, to assure immediate improvement of selected emergency operating and some other operating procedures for operating reactors and near-term operating license applicants.

Specific actions are being taken for near-term operations, and actions that will lead to new and better procedures will then be considered for the longer term. In the long term, symptoms-oriented approaches to abnormal and emergency procedures will be evaluated.

This effort will be coordinated with control room, simulator, and training improvements.

These actions will be integrated with new operating instruments for diagnostic purposes based on the assumption that adequately trained personnel can perform the specified actions. The need for coordination and training of plant per-sonnel is recognized.

1. Short-term accident analysis and procedures revision.a. Description:

There is an ongoing three-phase program for improving the analysis of design basis and off-normal transients and accidents and the procedures for handling such transients and accidents (see NUREG-0578, Sec. 2.1.9)(1) Small-break loss-of-coolant accidents (LOCAs). NRR sent letters of September

13 and 27, October 10 and 30, and November 9, 1979 referencing Section 2.1.9 of NUREG-0578 to licensees of operating plants, pending operating I. C-1 Task I.C May 1980 license applicants, licensees of plants under construction, and applicants for construction permits. The staff required that analyses be performed and guidelines prepared to develop emergency operating instructions for handling small-break loss-of-coolant accidents.

Appropriate retraining of operators was also required (see also Item I.A.2.1).

Guidelines were prepared for each class of operating plants and were reviewed and approved by the NRR staff.Detailed emergency operating procedures have been or are being prepared for each operating and near-term operating plant to implement the approved guide-l.ines for handling small-break LOCAs. An NRC audit team (with NRR leading and IE participating)

performed reviews of procedures for lead plants designed by each reactor manufacturer.

Procedures for the remaining operating plants will be reviewed by IE. For each plant that is being reviewed for an operating license, NRR and IE will review the small-break LOCA emergency operating instructions.

(2) Inadequate core cooling. In letters of September

13 and 27, October 10 and 30, and November 9, 1979, NRR required operating licensees, pending operating license applicants, licensees of plants under construction, and applicants for construction permits to perform analysis including preparation of emergency procedure guidelines and to develop procedures and conduct training to assist the plant operating staff to (a) recognize and prevent impending core uncovering and (b) recover from a condition in which the core has experienced inadequate core cooling (see also Item I.A.2.1).

An NRR team, with IE members, will review these procedures on an audit basis for lead operating plants. 1E will review the procedures for the remaining operating plants.(3) Transients and accidents.

In letters of September

13 and 27, October 10 and 30, and November 9, 1979, NRR required licensees of operating plants, operating license applicants, licensees of plants under construction, and pending construction permit applicants to perform analyses of transients and accidents, prepare emergency procedure guidelines, upgrade emergency procedures, including procedures for operating with natural circulation condi-tions, and to conduct operator retraining (see also Item I.A.2.1).

Emergency procedures are required to be consistent with the actions necessary to cope I. C-2 Task I.C May 1980 with the transients and accidents analyzed.

Through discussions with the owners' groups, NRR provided guidance for the performance of this task. NRR will review the responses, which are due in early 1980. In the course of review of these matters on B&W designed plants, the staff will followup on the Bulletin and Orders matters relating to analysis methods and results, as listed in Appendix C. See Table C.1, Items 3, 4, 16, 18, 24, 25, 26, 27;Table C.2, Items 4, 12, 17, 18, 19, 20; and Table C.3, Items 35, 37, 38, 39, 41, 42, 47, 55, 57.(4) Confirmatory analyses of selected transients.

In addition to the analyses performed by the reactor vendors, analyses of selected transients will be performed by NRR, usinig the best available computer codes, to provide the basis for comparisons with the analytical methods being used by the reactor vendors. These comparisons, together with comparisons to other data, will constitute the short-term verification effort to assure the adequacy of the analytical methods being used to generate emergency procedures. (See also Item II.E.2.2.)

These analyses in the case of the B&W design will also be used to establish whether core-barrel check valves have been adequately modeled in the analysis by the vendor since the Three Mile Island accident.b. Schedule.(1) Guidelines for handling small-break LOCAs at operating reactors were reviewed and approved by NRR Bulletins and Orders Task Force in late 1979. Reviews of lead operating plants were performed as indicated in NUREG-0645.

1E will conduct reviews of remaining operating plants by June 1, 1980. Reviews of operating license applicants will be consistent with operating license review schedules.

(2) Audits of lead operating plants will be completed in FY80.Reviews for the remaining operating plants will be conducted by IE by April 1, 1981. Reviews of operating licensee applicants will be consistent with operating license review schedules.

I.C-3

-Task I.C May 1980 (3) Reviews of analyses of transients and accidents are to be initiated upon receipt of submittal from licensees and applicants in early 1980.(4) Confirmatory analyses of selected transients are to be complete by June 1980.c. Resources:

See also Table C.3, Item 52.b. Schedule:

The requirement will be issued by May 15, 1980. IE will audit implementation in normal course of routine inspections.

c. Resources:

NRR FY80 -0.3 my, FY81 -0.1 my; IE FY60 -0.2 my.I.C-5 Task I.C May 1980 6. Procedures for verification of correct performance of operating activities.

a. Description:

NRR will require that licensees procedures be reviewed and revised, as necessary, to assure that an effective system of verifying the correct performance of operating activities is provided as a means of reducing human errors and improving the quality of normal operations.

This will reduce the frequency of occurrence of situations that could result in or contribute to accidents.

Such a verification system may include automatic system status monitoring, human verification of operations and maintenance activities, independent of the people performing the activity (see NUREG-0585, Recom-mendation

5) or both.Implementation of automatic status monitoring if required will reduce the extent of human verification of operations and maintenance activities but will not eliminate the need for such verification in all instances.

The procedures adopted by the licensees may consist of two phases -one before and one after installation of automatic status monitoring equipment, if required, in accordance with Item I.D.3. See also Table C.1, Item 5.b. Schedule:

The requirement will be issued by July 1, 1980. IE will audit implementation in normal course of routine inspections.

c. Resources:

NRR FY80 -0.2 my; IE FY81 -0.3 my.7. NSSS vendor review of procedures.

a. Description:

Applicants for near-term operating licenses will be required to obtain NSSS vendor review of low-power and power-ascension test and emergency procedures (see Regulatory Guide 1.33, Appendix A, Section 6) as a further verification of the adequacy of the procedures.

After trial use of this requirement on a few pending operating license applications, the staff will decide whether its further use or expansion to include procedure review by the A-E is desirable.

This decision will be made in light of the long-term program described in Item I.C.9. See also Table C.1, Item 4a and Table C.3, Item 50.I.C-6 Task I.C May 1980 b. Schedule:

The requirement will be issued by May 15, 1980. It will audit implementation in the normal course of routine inspections.

c. Resources:

NRR FY80 -0.1 my, FY81 -0.1 my; IE FY80 -0.1 my, FY81 -0.2 my.8. Pilot monitoring of selected emergency procedures for near-term operating license applicants.

a. Description:

An interdisciplinary and interoffice NRC task force will audit emergency procedures received from near-term operating license applicants.

They will look especially at the sections that discuss symptoms and immediate actions. This review will provide a sense of the adequacy of the emergency procedures.

In conjunction with the procedure review, the task force will also review the training related to the symptoms of the postulated transients.

The task force will conduct an in-depth review of selected emergency procedures.

The basic elements of the review will be the following:

(1) select specific procedures for review (e.g., small-break LOCA, loss of feedwater, loss of alternating current and restart of engineered safety features that were reset prior to power loss, steam-line break, or steam-generator tube rupture);

(2)meet with the vendor to discuss analyses and guidelines;

(3) meet with the applicant to discuss procedure preparation;

(4) observe a simulator walk-through of the selected procedures (with shift crew and shift technical advisor);

(5)observe a plant walk-through for one of the emergency procedures (observe shift crew, shift technical advisor, technical support center operation, operational support center operation, etc.); and (6) make findings on pre-paredness for the accidents covered by the selected procedures.

See also Table C.1, Item 4a and Table C.3, Item 49.b. Schedule:

This work will be completed on each pending operating license application prior to issuing a full-power license for that applicant.

Consideration will be given in FY81 to the extension of this program to a few operating plants of different design to increase the experience base prior to conclusion of item I.C.9.I.C-7 Task I.C May 1980 c. Resources:

NRR FY80 -3 my, FY81 -2 my; IE FY80 -1.3 my, FY81 -5 my; ADM FY80 -0.2 my and $7,000.9. Long-term program plan for upgrading of procedures.

a. Description:

NRC will develop a long-term program plan that will integrate and expand on current efforts in the writing, reviewing, and monitoring of plant procedures.

NRR will lead this effort and will receive significant support from IE, SD and RES. Studies to be considered in the plan will include how best to write plant procedures to assure that the wording of procedures is clear and concise; that the content of procedures reflects both engineering thinking and operating practicalities;

and that the format of procedures is clear including clear diagnostic instructions for identifying the particular abnormal conditions confronting the operator.

Studies will also address the proper interrelationships among administrative, operating, maintenance, test and surveillance procedures;

and the depth and content of regulatory and licensee review and monitoring of procedures.

The scope of the plan will include the transient analyses that form the basis of many of the emergency procedures, reliability analysis, human factors engineering, crisis management, and operator training.

Plant conditions in addition to those pertinent to the design basis will be considered, as well as administrative prohibitions to prevent improper operator actions during accident conditions that could cause serious threat to reactor safety. The plan will be coordinated with applicable industry groups. See also Table C.3, Item 49, 50, and 5L.b. Schedule:

The plan will be developed by July 1981.c. Resources:

PORV ISOLATION

SYSTEM (II.K.3.1)

POSITION (a) Ail PWR licensees should provide a system which uses the PORV block valve to protect against a small break LOCA. This system will automatically cause the block valve to close when the reactor coolant system pressure decays after the PORV has opened, to relieve excess-pressure.

An override feature should be incorporated.

Justification should be provided to assure that failure of this system would not decrease overall safety by Intensifying plant transients and accidents.(b) Each licensee should perform a confirmatory test of the auto-matic block valve closure system installed in response to (a)above.CLARIFICATION

Implementation of this action item has been modified in the forthcoming May 1980 version of NUREG-0660.

The change delays implementation of this action item until after the studies specified in Action Item II.K.3.2 have been completed, if such studies confirm that the subject system is necessary.

AUTOMATIC

TRIP OF REACTOR COOLANT PUMPS DURING LOCA (ILK.3.5)POSITION Tripping of the reactor coolant pumps in case of a LOCA is not an ideal solution.

The licensees should consider other solutions to the small break LOCA problem (for example, an increase in safety injection flow rate). In the meantime, until a better solution is found, the reactor coolant pumps should be tripped automatically in case of a small break LOCA. The signals designated to initiate the pump trip should be care-vully selected in order to differentiate between a small break LOCA and ot!er events which do not require reactor coolant pump trip as discussed in NIUREG-0623.

CLA.RIFICATION

Application to PWRs only. This action item has been revised in the May 1980 version of NUREG-0660

C-Urrently, the reactor core isolation cooling (RCIC) system and the high pressure coolant injec-ion (HPCI) system both initiate on the-same low water level signal and both isolate on the same high water level signal.The HPCI system will restart on low water level but the RCIC system will not. The RCIC system is a low-flow system when compared to the HPCI system. The initiation levels of the HPCI and RCIC system should be separated so that the RCIC system initiates at a higher water level than tne HCI system. Further, the RCIC system initiation logic should be modified so that the RCIC system will restart on low water level. These changes have the potential to reduce the nubmer of challenges to the H:?CI system and could result in less stress on the vessel from cold water injection.

Analyses should be performed to evaluate these chances.The analyses should be submitted to staff and changes should be implemented if justified by the analyses.CLARIFICATIONg This item is applicable to BWRs with RCIC and HPCI systems.L 1SOUSSION I:JREG-0526, Section A-2.3 SCHEDULE Analysis:

POSITION Isolation condensers have radiation monitors on their vents. These monitors provide alarms in the control room but do not isolate the isolation condenser.

The isolation condensers are currently isolated on a high radiation signal in the steam line leading to the isolation condensers.

The design should be modified such that the isolation condensers are automatically isolated upon receipt of a high radiation signal at the vent rather than at the steam line. The purpose of the change is to increase the availability of the isolation condensers as heat sinks.CLARIFICATION

LOGIC TO PREVENT SPURIOUS ISOLATION OF HiPi AND RCIC SYSTEMS (II.K.3.l5)

PO5 IT ION The HCI and RCIC systems use differential pressure sensors on elbow taps in 'he steam lines to their turbine drives to detect and isolate pipe breaks in the systemns.

The pipe break detection circuitry has resulted in spurious isolation of the HPCI and RCIC systems due to the pressure spike which accompanies startup of the systems. The pipe break detection cir-cuitry should be modified so that pressure spikes resulting from HPCI and RCiC system initiation will not cause inadvertent system isolation.

REDUCTION

AND FAILURES OF RELIEF VALVES -FEASIBILITY

STUDY AN'D SYSTEM 1MODIFICATION

-(II.K.3.16)

POSiTION;The record of relief valve failures to close for all BWRs in the past three years of plant operation is approximately

30 in 73 reactor years (0.41 failures/reactor year). This has demonstrated that the failure of a relief valhe to close would be the most likely cause of a small-break LOCA. The hich failure rate is the result of a high relief valve challenge rate and a relatively high failure rate per challenge

(0.16 failures/challenge).

Typically, five valves are challenged in each event. This results in an equivalent failure rate per challenge of 0.03. The challenge and failure rates can be reduced in the following ways: (1) Additional anticipatory scram on loss of feedwater, (2) Revised relief valve actuation setpoints, (3) Increased emergency core cooling (ECC) flow, (4) Lower operating pressures, (5) Earlier initiation of ECC systems, (6) Heat removal through emergency condensers, (7) Offset valve setpoints to open fewer valves per challenge, (8) Installation of additional relief valves with a block or isolation valve feature to eliminate opening of the safety/relief valves (SRVs), consistent with the ASME Code, (9) Increasing the high steam line flow setpoint for main steam line isolation valve (MSIV) closure, (10) Lowering the pressure setpoint for MSIV closure, (11) Reducing the testing frequency of the MSIVs, (12) More stringent valve leakage criteria, and (13) Early removal of leaking valves.An investigation of the feasibility and contraindications of reducing challenges to the relief valves by use of the aforementioned methods should be conducted.

Other methods should also be Included in the feasibility study. Those changes which are shown to reduce relief valve challenges without compromising the performance of the relief valves or other systems should be Implemented.

Challenges to the relief valves should be reduced substantially (by an order of magnitude).

ACCIDENTS A. OBJECTIVE:

To perform systems reliability analyses and to effect changes in emergency operating procedures and operator training to improve the capability of plants to mitigate the consequences of the small-break loss-of-coolant accidents (LOCA) and loss-of-feedwater events.B. NRC ACTIONS 1. It Bulletins.

a. Description:

Between April 1, 1979 and July 26, 1979 the Office of Inspection and Enforcement (IE) issued nine bulletins to various operating plant licensees, depending on the design of the reactor, and reviews of licensee responses were conducted by the NRR Bulletins and Orders Task Force. The responses were determined to be acceptable, and separate evaluation reports have been prepared and issued to some licensees.

The effort to complete these reports for all operating plant licensees is continuing.

NRR will require all operating license applicants to evaluate their plants against the requirements specified in applicable IE Bulletins and not otherwise addressed in this Action Plan, and to take corrective actions as necessary prior to fuel loading. Ultimately, these requirements will be codified by NRR and SD, as appropriate, and required of all plants as preconditions for receipt of an operating license.A comparison of the composite requirements from the nine bulletins with the action items in this plan is provided in Appendix C. The Bulletin requirements not covered by ac: .n items art listed below: (1) Review all -- ty-soated ialve positions and positioning requirements and positive zzr^:. as .e as al. redated test and maintenance procedures, to assure proper _rF 'jncticning, if required (see Appendix C, Table C.1, I'em 5).II.

procedures for removing safety-related systems from service (and restoring them to service) to assure that operability status is known (see Appendix C, Table C.1, Item 10).(3) Provide a trip for the pressurizer low-level bistable so that the pressurizer low-pressure signal alone (rather than the low-level/low-pressure coincidence)

will trip the reactor. For testing, provide for resetting the pressurizer low-level bistable (see Appendix C, Table C.1, Item 17).(4) Provide procedures and training to operators for prompt manual reactor trip for LOFW, TT, MSIV Closure, LOOP, LOSG level, and PZR Low Level (see Appendix C, Table C.1, Item 20).(5) Provide automatic safety-grade anticipatory reactor trip for LOFW, TT, or significant decrease in SG level (see Appendix C, Table C.1, Item 21).(6). Describe automatic and manual actions for proper functioning of auxiliary heat removal systems when main feedwater system is not operable (see Appendix C, Table C.1, Item 22).(7) Describe uses and types of RV level indication for automatic and manual initiation of safety systems. Also describe alternative instrumentation and methods (see Appendix C, Table C.1, Item 23).b. Schedule:

NRR will complete the Bulletin evaluation reports for operating plants by March 31, 1980. NRR will issue requirements to all pending operating license applicants and all plants under construction by July 1, 1980.C. Resources:

NRR FY80 -..0 my, FY81 -0.8 my.2. Commission Orders on 3abcock and Wilcox plants.a. Description:

In April 1_979, i task group was established in NRR to perforn a generic assessment of Exciter transients in B&W-designed operating plan:s In light of -^ _.- ---2. The study concluded that the staff I I. K-2 Task II.K May 1980 did not have reasonable assurance that the B&W plants could continue to operate without undue risk to the health and safety of the public and that the plants should be shut down until certain actions were completed to the satisfaction of the staff. The B&W licensees committed to perform these actions and con-firmatory Orders were issued to formalize the agreements reached with the licensees.

The Orders included both short-term and long-term actions. The NRR Bulletins and Orders Task Force reviewed the licensee responses to the short-term actions in the Orders and issued safety evaluation reports lifting the Orders in the period between May 18, 1979, and July 6, 1979. (These are Items 1 through 12 in Appendix C, Table C.2.) Additional items were identified in the review that required further work by the licensees.

These items are numbered 13 through 21 in Appendix C, Table C.2; all 21 items are to be implemented by operating B&W reactors.

However, because some were suspended by actions elsewhere in this plan, only seven of these actions apply to operating license applicants with B&W reactors (see Table C.2, Appendix C). License applicants with B&W plants will be required by NRR to demonstrate conformance with these seven requirements prior to operating license issuance.b. Schedule:

NRR will complete the evaluation of operating plant licensee implementation of residual actions originating from short-term actions and the implementation of long-term actions of the confirmatory Orders by January 1, 1981. NRR will issue these seven unique requirements, described above, to B&W designed plants now under construction by July 1, 1980.c. Resources:

NRR FY80 -1.5 my, FY81 -2 my; IE FY80 -0.5 my, FY81 -0.5 my.3. Final recommendations of B&O Task Force.a. Description:

The Bulletins and Orders Task Force has conducted gereric reviews aI the loss-of-feedwater (LOFW) and small-break loss-of-coclant events on operating PWRs designed by B&W, Westinghouse (W), and Comn-bustion Engineering (CE), and on operating BWRs. These reviews consisted of II. K-3 Task I.K May 1980 an evaluation of systems reliability analyses, guidelines for emergency proce-dures, and operator training related to these events. From these reviews, a number of recommendations for improvements were developed and issued in reports NUREG-0565 (B&W), NUREG-0611 (W), NUREG-0626 (GE), NUREG-0635 (CE), and NUREG-0623.

Upon approval of these recommendations (shown in Table C.3, Appendix C), NRk will notify licensees of the actions to be taken with respect to system modifica-tions, additional analyses, improved emergency procedures, and improved operator training related to the loss of feedwater and small-break LOCA events. The ACRS will advise NRR in early 1980, after which NRR will review and evaluate licensee commitments and/or actions required.On a case-by-case basis, NRR will propose the schedule on which these generic requirements must be met by near-term operating license applicants during calender year 1980 (i.e., before fuel loading, before full-power operation, or later). Ultimately, these generic requirements will be codified by NRR and SD and will be applied to all plants as preconditions for receipt of an operating license.b. Schedule:

NRR will issue requirements to operating plant licensees On early 1980 and will review the responses on a schedule to be completed in'983. Near-term operating license applicants are being advised of the specific requirements in this area on a case-by-case basis.c. Resources:

Control Room Habitability Requirements Position In accordance with action item III.D.3.4, Control Room Habitability, licensees shall assure that control room operators will be adequately protected against the effects of accidental release of toxic and radioactive gases and that the nuclear power plant can be safely operated or shut down under design basis accident conditions (Criterion

19, "Control Room," of Appendix A, "General Design Criteria for Nuclear Power Plants," to 10 CFR Part 50).Clarification All facilities that have not been reviewed for conformance with the following sections of the Standard Review Plan: 2.2.1-2.2.2 Identification of Potential Hazards in Site Vicinity;2.2.3 Evaluation of Potential Accidents;

6.4 Habitability Systems;shall perform the necessary evaluations and recommend appropriate modifica-tions to meet control room habitability requirements.

The following docu-ments may be used for guidance in performing the. required evaluations:

1. Regulatory Guide 1.78, "Assumptions of Evaluating the Habitability of a Nuclear Power Plant Control Room During a Postulated Hazardous Chemical Release." 2. Regulatory Guide 1.95, "Protection of Nuclear Power Plant Control Room Operators Against an Accidental Chlorine Release." 3. K. G. Murphy and K. M. Campe, "Nuclear Power Plant Control Room Ventilation System Design for Meeting General Design Criterion

19," 13th AEC Air Cleaning Conference, August, 1974.The licensees submittal shall include the results of the analyses of control room concentrations from postulated accidental release of toxic gases and

-2-control room operator radiation exposures from airborne radioactive material and direct radiation resulting from design basis accidents.

The toxic gas accident analysis should be performed for all potential hazardous chemical releases occurring either on the site or within five miles of plant site boundary.

Regulatory Guide 1.78 lists the chemicals most commonly en-countered in the evaluation of control room habitability but is not all-inclusive.

The DBA radiation source term should be for the LOCA containment leakage and ESF leakage contribution outside containment as described in Appendix A and B of Standard Review Plan Chapter 15.6.5. In addition, BWR facility evaluations should add any leakage from the main steam isolation valves (e.g., valve stem leakage, valve seat leakage, main steam isolation valve leakage control system release) to the containment leakage and ESF leakage following a LOCA. Other DBA's should be reviewed to determine whether they might constitute a more severe control room hazard than the LOCA.In addition to the accident analysis results which should either identify the possible need for control room modifications or provide assurance that the habitability systems will operate under all postulated conditions to permit the control room operators to remain in the control room to take appropriate actions as required by General Design Criteria 19, the licensee should submit sufficient information needed for an independent evaluation of the adequacy of the habitability systems. Attachment

1 lists the in-formation that should be provided along with the licensee's evaluation.

ACTION- (Class II)Licensees should submit their responses to this request on or before January 1, 1981. Modifications needed for compliance with the control room habitability requirements specified in this letter should be identified and a schedule for completion of the modifications should be provided.

Implemen-tation of such modifications should be started without awaiting for the results of the staff's review. Additional needed modifications, if any, identified by the staff during its review will be specified to licensees by July 1981. All modifications must be scheduled for completion by January 1, 1983.

Task III.D.3 May 1980 TASK III.D.3 WORKER RADIATION

PROTECTION

IMPROVEMENT

A. OBJECTIVE:

Improve nuclear power plant worker radiation protection to allow workers to take effective action to control the course and consequences cf an accident, as well as to keep exposures as low as reasonably achievable (ALARA) during normal operation and accidents, by improving radiation protec-ticn plans, health physics, inplant radiation monitoring, control room habitability, and radiation worker exposure data base.B. NRC ACTIONS 1. Radiation protection plans.a. Description:

NRC will require all licensees to prepare and implement radiation protection plans (RPP) that will incorporate commitments to criteria in existing Regulatory Guides, including Regulatory Guide 8.8, and Standard Review Plan Chapter 12, as well as criteria to be developed from analysis of tl.e _ appraisal of health physics programs at all operating sites. The RPP wi l be integrated into the emergency plan to assure worker protection without..restricting accident mitigation and recovery.The results of the following task action items will be incorporated into the RP; Item I.A.1, "Operating Personnel and Staffing," to determine the necessary nurber and types of radiation protection personnel for each shift and to investigate the desirability of separation of the radiation protection and chemistry functions;

Item I.A.2, "Training and Qualifications of Operating Personnel," to review the training program for radiation protection personnel and develop new regulations or guides for such personnel;

Item I.A.3, "Licensing ant Requalifications of Operating Personnel," to study the need for licensing r_ ,atjn protection personnel;

and Item I.B.1, "Organization and Management.riteria," to determine the organization and qualifications of the radiation protection staff.III.D.3-1 Task III.D.3 May 1980 (1) NRR will, in cooperation with IE and SD, precare a draft Guidie for the preparation of an RPP that will include an existing draft Guide on'-7]ementaticn of ALARA at Operating Plants." (2) NRR will develop acceptance criteria using existing regulatory guices, the Standard Review Plan, and information to be developed on the bas s of feedback from ongoing IE comprehensive appraisals at all operating reactors to assess the adequacy of existing radiation protection programs.(3) NRR will publish for review and action by licensees the draft RPP Guide (see item 1 above), which will specify format, content, and acceptance criteria, including guidance on implementing ALARA at operating plants and will send an information notice to licensees providing clarification that all health physics personnel, including temporary contractor personnel, must meet the tech-nical specification training and qualifications requirements.

(4) NRR will hold regional meetings to discuss Implementation of RPPs and to receive comments on improvements in the draft Guide.(5) NRR will revise the draft Guide based on the feedback obtained at the regional meetings and from IE.(6) NRR will require licensees to provide RPPs and request amendment of technical specifications, including a commitment to ixplement the RPP.(7) NRR will review the RPPs and, for reference, the amended technical specifications.

(8) NRR will revise Standard Review Plan Section 12.5, "Health Physics Proc-am," to include the RPP Guide in the acceptance criteria.(9) SD will revise Regulatory Guide 1.70, "Standard Format and Content cF Safety Analysis Reports for Nuclear Power Plants." b. Schedule:

a. Description:

The accuracy of health physics measurements for both routine and emergency conditions is to be improved.

Accurate high dose rate warning devices and radioiodine respiratory protection are needed.(1) SD will amend 10 CFR 20 to require that personnel dosimetry processing be done only by nationally certified processors who meet specific performance criteria (utilities could themselves become certified if they desire).(2) SD will issue a regulatory guide containing specifications for audible alarm dosimeters and criteria for their use.(3) SD, in cooperation with the American National Standards Institute (A.ISI), will develop standard performance criteria for radiation survey and monitoring instruments.

SD will contract for performance testing of on-the-shelf instruments to determine feasibility of the standards.

NRC will adopt a final standard and require that only instruments meeting the standard be used at licensed facilities.

(4) Under contract with RES, the Los Alamos Scientific Laboratory will develop a method for testing and certifying air-purifying respirators for use against radioiodines.

The method and equipment will be transferred to NIOSH, and NIOSH will be requested to amend 30 CFR 11 to incorporate the method into respirator test and certification schedules.

NRR will evaluate the need to specify the quantity and types of respirators necessary for normal and emergency use.N I.0.3-3 Task III.D.3 Mlay 1i80 b. Schedule:

This is a Decision Group 0 item. Therefore, schedules and resources are to be developed in connection with routine agency oudgetary Processes.

c. Resources:

a. Description:

Licensees are to improve systems for monitoring inplant radiation and airborne radioactivity with instruments appropriate for a broad range of routine and emergency conditions and to provide calibration methods for such instruments.

(1) NRR has issued a letter requiring improved radioiodine sampling instrumentation (NUREG-0578, 2.1.8.c).(2) NRR will set criteria requiring licensees to evaluate in their plants the need for additional survey equipment and radiation monitors in vital areas and requiring, as necessary, installation of area monitors with remote readout. NRR will evaluate the need to specify the minimum types and quantities C, portable monitoring instrumentation, including very high dose rate survey instruments.

Operating reactors will be reviewed for conformance with Standard Review Plan Section 12.3.4, "Area Radiation and Airborne Radioactivity Monitoring Instrumentation." NRR will revise Standard Review Plan Sections 12.5 ana +/-2.3.4 to incorporate additional monitor requirement criteria.

I'E w..ill inspect implementation.

(3) SD will issue a rule change providing acceptable methods for cavibration of radiation-monitoring instruments.

(4) SD will issue a Regulatory Guide providing acceptable methods-r calibration of air-sampling instruments.

III. D. 3-4 Task III.D.3 May 1980 b. Schedule:

NRR issued requirements regarding radioiodine monitoring by letter to operating plant licensees on October 30, 1979; NRC work on require-ments regarding area monitors and portable instrumentation rill be initiated In FY82, or later. Items (3) and (4) above are Decision Group D items; schedules and resources are to be developed in connection with routine agency budgetary processes.

c. Resources:

IE FY80 -0.1 my, FY81 -0.2 my; ADM FY 80 -0.1 and $5,000, FY81 -0.1 my and $5,000.4. Control room habitability.

a. Description:

NRR will follow a two-step approach to assure that workers are adequately protected from radioactivity', radiation, and other hazards, and that the control room can be used in the event of an emergency.

First, NRR will require all facilities that have not been reviewed for conformance to Regu-latory Guides 1.78 and 1.95 and Standard Review Plan Sections 2.2.1, 2.2.2, 2.2.3, and 6.4 to do the evaluations and establish a schedule for necestary modifications.

This will be a condition of full-power operation for near-tarm operating license facilities.

Then, NRR will, in conjunction with the rulenaking proposed in Item II.B.8, examine and evaluate other sources and pathways of radioactivity and radiation that may lead to control room habitability problems, and will, if necessary, make changes in the requirements of the Regulatory Guides and the Standard Review Plan. Such potential internal (to the plant) pathways for potential control room contamination were flagged by the TMI-2 accident.Review and quantification of potential control room operator doses due to such airborne radioactivity ingress and radiation penetration from pathways internal to plant structures will be the basis for such changes.b. Schedule:

NRR will issue the requirements for operating reactors by[lay 1980, regarding the existing criteria listed above. NRR will complete evalua-tion of licensee responses and notify licensees of acceptance by July 1981.1E will complete inspections on a case-by-case basis for conformance by no later than July 1983. Longer term changes in criteria will be dependent on the results of the rulemaking proceeding on degraded cores.III. 0. 3-5 Task III.0.3 May 1980 c. Resources:

NRC will continue its efforts to improve and expand the data base on industry employees to facilitate possible future epidemiological studies on worker health.(1) The NRC staff has been actively engaged in this and similar efforts for some time. Examples are our participation in the working groups of the interagency Task Force on the Health Effects of Ionizing Radiation (the so-called Li-assi Committee), the Fredrickson Committee on Federal Research on the Biological Effects of Ionizing Radiation Research (NIH), and the Upton Subcommittee on T.1I Followup Studies (NIH).More recently, NRC and NIOSH have been cooperating to establish a worker registry at TmlI to facilitate possible future health studies. We also have been in contact with -PRI to investigate expansion of our efforts to the entire U.S. nuclear utility industry.

In addition, SD has funded an epidemiology feasibility and planning study which, among other things, will provide information on how to-t.Zrove the worker's health and exposure data base.SO will develop a format for data to be collected by utilities regarding total radiation exposures to workers, as well as other data pertinent to eventual epidemiological studies. These data will include both external and internal doses, medical radiation exposures, health data, and exposure to nonradioactive carcinogens (both within and outside of the workplace).

(2) NRC will investigate methods of obtaining employee health data i: ,onlegislative means until such time as legislation is passed allowing routine collection of these data by NRC.(3) SD will, following appropriate legislative action to permit such regulatory requirement, revise 10 CFR 20 to require licensees to collect worker data.III. 0. 3-6 Task III.D.3 May 1980 b.
