N I1j 3 ISSUE DATE: 10/15/79 48!60Bi UL d J mhu/n MINUTES OF THE MI-2 ACCIDENT IMPLICATICUS (SALEM) SU3CCMMITTEE MEETING JULY 27, 1979 WASHINGTON, DC A meeting of the Ad Hoc Subcommittee on the tree Mile Island 2 Accident Implications was held in Room 1046, 1717 H Street, Washington, DC on July 27, 1979. We purpose of the meeting was to develop information that will assist the full ACRS in reaching a decision on what requirements from the W I accident will be applied to plants in the near-term license stage, specifically a Westinghouse-type reactor, Salem 2.

We meeting was noticed in the Federal Register dated July 12 and 20, 1979, which are included as Attachment A.

"ihe schedule of the meeting and the attendee list are in-cluded in Attachment B and C, respectively. Handouts at the meeting are included as Attachment D.

No request to make a statement at the meeting from the public was received. We meeting was held in open session.

EXECUTIVE SESSION Dr. Siess opened the meeting by stating that the ACRS at the June meeting had reached a position on how it plans to handle plants with near-term OLs.

He then read the pertinent portion of the letter that was transmitted to the Staff, as follows: "The Committee expects that the NRC Staff will keep it informed regarding the additional requirements arising.from consideration of the IMI-2 accident being imposed on those plants in which the ACRS has already reported to the Commission on OL applications but for which the OL l

has not yet been issued. We information supplied to the ACRS may be pro-vided either case-by-case or in generic form, as appropriate. The ACRS expectes to review this information and any actions proposed by the Staff and to report thareon to the Commission 'atten considered appropriate by the l

Committee, or as requested by the Commission."

. The Staff had chosen to present this information in generic form as NURDG-0578, "TMI-2 Lessons Learned Task Force Status Report, Short-Term Recommendations."

This repart includes recommendations relating to all operating reactors and to all pending operating licenses.

Dr. 'Siess suggested that the scope for today's meeting should be limited to those things which affect the near-term OLs.

Additional recommendations will be forthcoming from the Bulletins and Orders Task Force for the six near-term OLs of the highest priority interest, the Westinghouse plants. These additional recomendations will be in a Westing-house generic report being written by the Bulletins and Orders Task Force.

There will also be other recommendations in the near-term associated with operator training and licensing.

The Staff stated that the 23 recommendations in NUREG-0578 have been trans-mitted to Mr. Denton for action. The Staff feels that all 23 recom.rendations will be approved with only minor changes.

BULLETINS AND ORDERS - S. Israel, NRC Staff Mr. Israel discussed the requirements that the Bulletins and Orders nystem group will be applying to the PWR plants.

Since there is an overlap in some of the recommendations with the Lessons Learned Task Force, only those not in the Lessons Learned Task Force were discussed by Mr. Israel.

In the area of the auxiliary feedwater system, the following items were discussed:

single suction valve

- alternate water source

- condensate storage tank low level alarm

- pump endurance test

. - water hammer flow

- valve position on loss of air

- actuation on loss of all AC

- technical speci'ications

~

In the area of instrumentation, core exit thermocouples that will be monitored in the control room was discussed.

In the procedures area, smll LOCA, extended loss of feedwater, and steam generator dump valve operation were discussed.

2 e program discussed above will be implemented before the near-term OLs are issued.

E.v.ERGENCY PLANNING - J. Miller Mr. Miller represented a group that reviewed emergency planning for all sites including the near-term OLs. He stated that the charter of the group is to implement Regulatory Guide 1.101 to assure the implementation of the Lessons Learned Task Force on operating reactors and near-term OLs, and to assure that the relationship between licensees, and state and local agencies concerning the emergency plans is firmed up.

He further stated that emergency planning will be applied to a distance of 10 miles from the plant, and that test exercises of j

emergency plans involving both state and local levels, including the licensee, will be required. Implementation schedule is July 1,1980.

i TRAINING - R. Bursey Mr. Bursey discussed new training requirements for operators to be licensed in new plants. We training requirements are listed in a Commission paper which will be subnitted for considereatien at a later date. Some of the requirements of the oral and written examinatior.s include all of the MI-related material, response to the Bulletins and Orders, and expansion of the material on heat transfer, fluid flow, and thermodynamics.

In addition, all Unit 1 personnel of a multi-unit facility of the near-term OLs will be evaluated on the basis l

. of grades achieved during the last annual requalification examination.

If an individual received a grade less than 80 percent (formerly 70 percent) overall, he will be required to take a regular examination; if he is an SRO, he will have to take the regular RO and SRO examinations.

The Staff is attempting to requalify current operators of operating plants.

The problem, in part, stems from the unavailability of training slots at a simulator.

In the meantime, the operators of the near-term OLs will be more thoroughly trained than the operators of operating plants.

NUREG-0578, LESSONS LEARNED Dr. Siess then,went through, item by item, the 23 short-term recommendations delineated in NURE-0578. 'Ihese recommendations are deemed by the Task Force to provide substantial additional protection for the public health and safety.

Some of the items of particular interest to the Subcommittee are listed as follows:

Post-Accident Hydrogen Control Systems

- Instrumentation to Follow the Course of an Accident

- Shift Tehnical Advisor

- Revised Limiting Coditions for Operations GENERAL DISCUSSION The Chairman asked if Salem had any problems in meeting the requirements in NUREG-0578. The Applicants stated that, in general, no problems exist in implementing the recommendations in NURE-0578, but they may have space prob-blem for the on-site technical support center. The Staff stated that it should not be a problem because proximity was meant by the Staff to mean that people could be sent to and from the plant conveniently. The center can be "a block" away from the plant.

. i de Subconmittee is still concerned that some plants still require AC power j

for the auxiliary feedwater system to operate. We Staff stated that this concern is now bei.9 addressed by a dedicated task force.

Ice condenser and BWR plants were not covered at this meeting, but were sched-l uled to be addressed at future meetings.

We Subcommittee then agreed to present the Salem 2 matter at the full ACRS meeting scheduled for August.

NOTE: For additional details, a complete transcript of the meeting is available in the NRC Public Docunent Room,1717 H St., NW, Washington, DC 20555 or from Ace-Federal Reporters, Inc., 444 North Capitol St.,

s July 18, 1979 MEMORANDUM FOR: Harold R. Denton, Director Office of Nuclear Reactor Regulation FROM:

Roger J. Mattson, Director TMI-2 Lessons Learned Task Force

SUBJECT:

TMI-2 LES50t45 LEARNED TASK FORCE rep 0RT (SHORT TERM) NUREG-0578 Enclosed is the first report of the 'TMI-2 Lessons Learned Task Force.

It contains a set of short term recommendations to be implemented in two stages over the next 18 months on operating plants, plants under There are construction, and pending construction permit applications.

23 specific recomendations in 12 broad areas (nine in the area of design and analysis and three in the area of operations).

The 23 recom-mendations would provide substantial, additional protection which is required for the public health and safety.

All but one of the 23 recomendations have a majority concurrence by the The exception is the recomended requirement to provide Task Force.

capability to install an external recombiner at each reactor plant forThe post-accident hydrogen control, if necessary following an accident.

majority of the Task Force recommends that this matter deserves further evaluation in conjunction with other hydrogen generation and contrcl questions being reviewed by the Task Force for its final report.

Three of the recomendations appear to require changes in existing regulatforts for which the Task Force recommends immediately effective rulemaking. They are:

The 23 recommended actions were discussed with the Re'gulatory Requirements Review Committee (June 22, 1979), the Commission (June 25,1979), the 11, 1979), and the ACRS (July 12, 1979).

'2 Harold R. Denton The Task Force recommends that time not be taken to request and evaluate public coments on these short term requirements prior to their promulgation as licensing requirements or rules because they are safety significant matters that require prompt application to operating reactors and operating license Other TMI-2 accident review groups apolications in the late stages of review.

and the Lessons Learned Task Force are continuing to evaluate the longer term implications of the accident. Any public coments on the short term recom-mendations that are received after their issuance (just as in the case of the earlier IE Bulletins) can be factored into those continuing evaluations.

Having identified the 23 specific recomendations for short tern action, the Lessons Learned Task Force will turn to the broader, more fundamental regulatory questions which should be addressed in the longer term (some of them likely to require evaluations that extend beyond the life span of the These longer Task Force) before other regulatory actions are recomended.

On July ll, I solicited the comments of the principal NRR line organizations on the final draf t of the report and its central conclusior regarding the necessity and ' sufficiency of the short term recomendations for continued operations and licensing. General support for the conclusions of the Task Force report was expressed by all of the principal NRR line managers.

We have reviewed and considered the detailed comments supplied by the vario, NRR organizations in the course of their review. Where appropriate, The principal we made clarifying changes in the language of the report.
