  • Investigation into the March 28, 1979 Three Mile Accident by Of fice of Inspect ion and Enforcement .

1320 044 -

Following the TMI-2 accident, Metropolitan Edison Company recognized through its own and other investigations of the accident that major organiza-tional changes were desirable for more ef fective management control. These changes indicate Met-Ed's commitment to operational safety and provide signi-ficant improvement in the control of opera -

.a1 activities, and the technical and management resources directing and supporting facility operations.

The first step taken was to combine the cechnical and management resources of Met-Ed and GPU Service Corporation Generation Divisions into a single organizational entity identified as the TMI Generation Group.

The TMI Generation Group was formed on July 30, 1979, to strengthen the overall management a,3 provide greatly increased technical resources for the restart of TMI Unit 1 and the recovery of TMI Unit 2. The Group is headed by R. C. Arnold. To effect this new organization, Mr. Arnold was elected to the position of Senior Vice Presi. nt of Met-Ed, and he continues to serve as a Vice President of GPU Service Corporation. In this position, Mr. Arnold reports to Herman M. Dieckamp, President of GPU and GPUSC, and acting president of Met-Ed. This reporting structure provides a direct link from the Chief Operating Of ficer of these three companies to the activities at TMI. A primary objective of the TMI Generation Group is to insure that NRC Regulations, Technical Specifications and established procedures are adhered to. As head of the TMI Generation Group, Mr. Arnold directly supervises the following functional groups.

THE hET-ED NUCLEAR OPERATIONS The head of this group, Mr J. G. Herbein, Vice President - Nuc1 car Operations (Plant Manager) is serving full time at TMI and his responsibilities and functions are described in Section 5.2.1.

1320 045

Formerly, Mr. Herbein held the position of Vice President - Generation, Met-Ed, where he had the responsibility for directing the engineering, operations and maintenance of Met-Ed's fossil fuel and nuclear power plants.

The organization formed under Mr. Herbein's direction specifically gives the Unit 1 Superintendent only the responsibility for operation and maintenance and relieves him of direction of administration, training, engineering, radiation protection and chemistry functions.

TECHNICAL FUNCTIONS The Technical Functions Group, directed by Mr. R. F. Wilson, provides ofi-site technical support to TMI operations. This includes engineering and design support for Unit 1 equipment modifications, systems engineering and safety analysis.

The Engineering and Design Department of the Group is organized into the following sections:

Electrical Power and Instrumentation Mechanical System Engineering Engineering Mechanics Mechanical Components Engineering The System Engineering Department is organized into the following sections:

Control and Safety Analysis Process Computer Nuclear Analysis and Fuels Plant Analysis 1320 046  ;

i e

i i

f

The Plant Analysis section has been specifically established to focus on systematic review of the performance of plant systems and to provide corporate direction of site engineers who will be monitoring, independent of operation personnel, plant performance on a daily basis.

A TMI Engineering Management sectien has also been established in the Technical Functions Group to provide direct liaison and coordination between corporate engineering support and the plant engineering activities. In addition, a very experienced engineer, formerly in a supervisory position, has been assigned on a full r.ime basis as Chairman of the Generation Review Committee to direct independent technical review of site modifications, procedure changes and plant experiences relating to nuclear safety.

MAINTENANCE The Director-Maintenance, Mr. J. L. C. Bachofer, Jr., is heading the on-site maintensnce organization which has the responsibility to support TMI Unit 1 in the areas of Corrective Maintenance, Emergency Maintenance, Bbintenance Procedures and Methods, Tools and Equipment, and Machinery History. Additionally, Mr. Bachofer is providing assistance to TMI Unit 1 in the construction of plant modifications, controls estimating / cost engineering, craft labor relations, and the coordination of transportation requirements.

ENVIROSMENT, HEALTH AND SAFETY The Director - Environment, Health and Safety, Mr. J. R. Thorpe, provides both on-site and off-site support to TMI Unit 1 in the functional areas of Nuclear Licensing, Environmental Engineering, and Environmental Impact Assessment.

RELI ABILITY ENGINEERING The Reliability Engineering Group, directed by Dr. R. L. Long, provides off-site and on-site Quality Assurance and System Laboratory support to the 1320 047

TMI Unit 1 operations. The Quality Assurance Department provides technical assistance to TMI Unit 1 in Methods and Operations, Materials Technology, Auditing, Design Assurance, Fbnufacturing Assurance as well as conducting appropriate quality control activities. The System Laboratory provides technical assistance to TML Unit 1 in Environmental and Operational Chemistry and Chemistry.

THE TMI-2 RECOVERY ORGANIZATION The Acting Director, TM1-2 Recovery, Mr. R. F. Wilson, provides overall management and direction for activities associated with the restoration of TMI-2 to operation. This organization will have an independent dedicated on-site staff necessary to conduct clean-up activities.

These changes have structured the organization so that substantially greater management resources are focused directly on TMI activities to insure adequate control of safety related activities. The current organi.~ation includes about 250 professional people with an average experience of about 13 years, composed with the approximately 75 professionals contained in the Met-Ed organization prior to the accident. To provide necessary involvement of corporate management and staff in operational activities, all the previously described groups have significant portions of their staffs located full time at TMI.

These changes, as well as improvements made in training, shift staffing, organizational status and staffing of the health physics departments of the two units, and strengthened administrative controls, are substantive and cicar indications of Met-Ed's commitment to insure the safe operation of TMI-1.

The upgrading of the Operational Quality Assurance Program is discussed in Section 5.4, page 5-32 to 5-38 and Figure 5.4-1 and 5.4-2 of the TML-1 Restart Report (Amendment 4). Major improvements have been made in the audit function with the establishment of an on-site QA Audit staff to better coordinate and manage audit activities and provide management with increased awareness of the adequacy and implementation of the QA Program. The following actions are being taken:

A. Current auditing procedures are being revised to better define responsibilities, provide simplified audit reporting and better follow-up of problem areas.

B. Surveillance and audit scheduling practices / procedures are being upgraded to provide an improved approach to coverage of activities affecting safety.

C. Corrective action procedures for QA Audits are being put in place to provide guidance so that corrective actions result in measures which preclude recurrence.

D. A computerized audit status system is being established to provide better management visibility of problem areas and to determine trends.

E. A conserted effort to establish priorities of audit findings and to commit the appropriate level of management, via the post audit conference, is being put in place to provide corrective actions that insure the commitment of sufficient resources.

8 Independent verification of operational activities effecting safety are  !

being assured by the following specific procedural requirements. These

{

l 1320 049 f

requirements essentially provide a check and cross check system which provides the assurance that SFAS and EFW Systems will perform in accordance wf ;h established requirements whenever challenged.

These procedural requirements are outlined below:

A. At each operations shift relief control room turnover, SFAS and EFW checklists that have been completed by the off going watch during shift are signed by both the on coming and off going control room operators. Completion of these SFAS and EFW checklists, which indicate both required and actual control room valve and switch position indications insures that all control room indications have been double checked to verify that SFAS and EFW Systems are in their ready to actuate status.

To verify in plant SFAS and EFW System valve positions, formal log sheets, indiccting both required and as found SFAS and EFW valve positions will be completed by primary, secondary and out building auxiliary operators. SFAS and EFW valve positions in major SFAS and EFW System flow paths, which do not have control room position indication, will be verified and recorded on the log sheets either once a shift or once a day, depending on case of accessibility and existing plant radiation levels.

Separate system status checklist requirements are also completed by the control room watch, primary plant, secondary plant and out building auxiliary operators during their 1320 050 i

I

P shift. These system status checklists are also reviewed and signed at shift turnover by the on coming and of f going auxiliary operators and control room watch.

B. At the completion of maintenance on SFAS and EFW Systems on independent system checklist is required to return the system maintained to full operational status. This checklist will encompass a specific system valve and breaker lineup within the boundaries in which maintenance was conducted. Additionally this checklist will require two independent review and signature verifications for correctness prior to its use in aligning the system in the field. Following this dual verification, the checklist will then be used in the field to return the system to full operational status.

C. Following surveillance tests or special operations on SFAS and EFW Systems, two independent valve and breaker lineups will be conducted within the boundary of the evstem affected by the tests or special operations to provide as.c. ance that the system is returned to full operational status.

D. Surveillance testing and the required testing following maintenance on instrumentation associated with SFAS, EFW, Reactor Protection System (RPS), and Radiation Monitoring System (RMS) instrumentation, will be accomplished according to procedural requirements which will require the technician performing the instrumentation test steps to initial each procedure step as it is accomplished. Following the completion

and sign off of the Surveillance test by the technician, a supervisor will review the completed procedure to verify all steps have been initialed, and that data is appropriately recorded and is within the required procedure authorized limits. Following this review the supervisor will also sign the completed procedure and related data sheets. Signed data sheets and initialed procedures will be retained.

Changes to review and approval provisions for plant and emergency procedures have been improved by the assignment,as mentioned previously, of a full time Generation Review Committee (GRC) Chairman who has extensive u.ility engineering experience, a degree in Electrical Engineering and was formerly a member of the Oyster Creek GORB. The full time GRC chairman will be responsible for executing review activities related to safety evaluations, procedure changes and violations of regulations. The function, composition, qualifica-tions, quorum and meeting frequency of the CRC will be specified in a proposed change to the Unit 1 Technical Specifications.

In summary, the GRC will be composed of at least five members. Each will have ar academic degree in Engineering or Physical Science with five years of technical experience. In view of the significant increase in both numbers of assigned professional personnel and years of experience the Generation Review Committee will have a strong technical base to provide in-depth support to insure that its functions are adequately executed.

In addition to the previously required Plant Operation Review Committee (PORC) review and Unit Superintendent approval required for nuclear safety related procedures, the Radiation Protection and Chemistry Supervisor or i

another individual knowledgeable in Radiological Controls will attend all PORC meetings where Radiologicai Control procedures and practices are reviewed.

Following the TMI-2 accident, an experienced consultant who formerly

' held the position of Branch Chief of NRC Operator Licensing, conducted a review of operating and emergency procedures as well as plant training practices. As a result of this review, several significant recommendations were incorporated into the plant emergency procedures. These included an " objectives section" for each emergency procedure outlining in a clear, concise summary, the overal. Intent, goal, and directional thrust intended by the execution of the eme gency procedure and its follovup action. Additionally, as a result of this review, emergency procedure follow-up actions will reverify important plant parameters utilized to categorize plant symptoms and initiate immediate action. These key parameters will be verified a second time in the follovup action utiliting, where possible, an alternate means cf readout or indication.

This will minimize the potential for misreading instruments and will provide a check on the accuracy of instruments read initially when evaluating emergency symptoms and executing the immediate action steps of emergency procedures.

This effort has resulted in the emergency procedures being revised to provide a sharply focused emphasis on maintenance of adequate core cooling at all times.

As a part of our review, key emergency procedures were used by shift crews at the B&W Lynchburg Simulator. Where required, procedure changes were initiated to insure technical accuracy, clarity and consistence with actual plant simulator response. Additionally, guidelines from B&W have been incorporated in the emergency procedures relative to small break LOCA, natural circulation, inadequate core cooling, prevention of void formation, and the 1320 053

high and low pressure injection modes of core cooling. Finally, the follow-up section of the emergency procedures has been expanded to include specific long term actions wherever appropriate.

Additional emphasis is being given to the area of training. The position Manager of Training was established, reporting directly to the Vice President-Nuclear Operations with the responsibility to organize, develop and conduct training programs to meet the train *ng requirements of the TMI Nuclear Station Unit 1. To assist the Manager of Training, a Supervisor of Operciar Training and a Supervisor of Technical Training have been assigned to 'plement the operator and technician training programs.

Major emphasis has been placed on the establishment of a Management Training '>rogram developed for management positions in the TMI-1 organization.

The course content will include:

A. Technical Specifications, Section 6.0 B. Kemeny Commission Report C. Operational Quality Assurance Plan D. TMI Emergency Plan E. Health Physics F. Decay heat removal and heat tronsfer mechanisms including core decay heat generation G. Safety Analysis Other training programs are outlined in Appendix I to this letter.

The above managerial and operational changes reflect our ongoing commitment to operational safety and awareness of the need to give clear visibility to that commitment. Safety will remain the chief concern of the 1320 054 ,

TMI Ceneration Group. The recommendations of the President's Commission on the Accident at Three Mile Island are being reviewed, as will be the forthcoming recommendations of the NRC/TMI Special Inquiry Group and other investigatory agencies, to assure the Company is appropriately responsive to all recommendations which relate to nuclear afety.
