2.0 OVERVIEW The major activities currently underway involving TMI promulgated im-provements are summarized below:
2.1 Control Room Design Review (CRDR) Program, as principally governed by references 4.3, 4.4 and 4.5.
2.2 Post Accident Instrumentation Program, which is mainly governed by references 4.2 and 4.3.
2.3 Emergency Procedures Program, as guided primarily by references 4.3 and 4.6.
2.4 Safety Parameter Display System (SPDS) Program, which is primarily governed by references 4.3 and 4.7. WNP-3 utilizes the term Emer-gency Data System (EDS) and this term will be used throughout this plan.
2.5 Plant Monitoring System (PMS) Program.
2.6 Off-site Dose Assessnent Program, as guided chiefly by reference 4.2.
2.7 Operating Procedures Program, which utilizes references 4.3 and 4.6 for guidance.
2.8 Emergency Preparedness Program, as guided mainly by references 4.3 and 4.10.
2.9 Operator Training Program, as governed primarily by reference 4.3.
The above programs involve multiple discipline elements-(e.g., Engineer-ing, Licensing, Operations, etc.) from the Supply System, Architect Engineer (Ebasco Services, Inc.), reactor vendor (Combustion Engineer-ing) and various consultants. All of the above efforts must ultimately be integrated into the operator and plant personnel training effort and subsequently shown to properly support plant operation.

3.0 PROGRAMMATIC ELEMENTS Reference 4.3 provides the primary NRC guidance with respect to criteria for post TMI improvements, which can be broadly categorized as involving enhancements to the control room, operator training / procedures and acci-dent monitoring instrumentation. Major WNP-3 programs involving these enhancements include:
a) Control Room Design Review (CRDR) b) Post Accident Instruments c) Emergency Operating Procedures d) Emergency Data System (EDS) e) Plant Monitoring System (PMS) f) Off-site Dose Assessment g) Operating Procedures h) Emergency Preparedness Program i) Operator Training Pigure 3-1 provides a simplified logic network for these programs and their interrelationships with a more detailed discussion provided later in this plan. Appendix B of this plan provides key milestone dates for the TMI Improvments Integration Effort.
A number of organizations from the Supply System, Architect Engineer, Reactor Vendor and consultants are involved in the TMI improvements effort, with overall coordination and integration provided under the auspices of the Project Completion Manager for WNP-3. Management control of the various reference 4.3 criteria is effected through the Project Change Management System while the status of the TMI improve-ments is followed by Project engineering. Appendix A is an organiza-tional chart for WNP-3 and is' provided for informational purposes.
3.1 Control Room Fesign Reviews (CRDR) Program The objective of the Control Room Design Review Program is to im-prove the ability of the control room operators to prevent acci-dents, as well as deal with those that might occur, by improving the qualf ty of the available information thereby facilitating appropriate responses.

- The CRDR Program is managed by the Supply System's WNP-3 Project Engineering organization, and heavily supported by the Plant Oper-ations organization. The Project Manager provides the decision
, authority for acceptance of the program and subsequent plant enhancements, with reference 4.5 being used as an acceptance guideline.
The CRDR Program is the core of the WNP-3 TMI improvements effort and is conducted pursuant to references 4.4. and 4.5, with imple-
- mentation being effected by the Supply System, the Architect Engi-neer (Ebasco), and human factors consulant(s) (Lund Consulting Inc.) with the reactor vendor (Combustion Engineering, Inc.) pro-viding support as necessary.
- The basic elements of the CRDR are listed and briefly discussed 1
below -- also see Figure 3-1.
3.1.1 Control Room Survey / Inventory - This phase of the program
) involves a survey of the existing control ~ room and compar-i ision with standardized human engineering guidelines.
I 3.1.2 System / Task Analysis - This phase of the program identi-fies and defines the functions and tasks performed in the control room. The effort is based on the reference 4.11 generic emergency guidelines developed by the Combustion Engineering Owners Group-(CE0G), as augmented by WNP-3 specific guidelines. In addition, information is utilized from the evolving Emergency Data System, Plant Monitoring System, and Post Accident Instrumentation Programs. The effort also provides feedback to the Emergency Operating Procedures Program.
3.1.3 Human Engineering Discrepancies (HEDs) - In parallel with ,
the preceding program elements', potential control room
. shortfalls i> _ human' engineering principles are developed.
The HED deveiopment efforts can generally be categorized as follows: ,
(1) Potential HED involving relatively easily correct-able shortfalls in control board format presenta-tion. These potential HEDs are developed from and with the control room survey / inventory effort.
(ii) Shortfalls in control room's ability to optimally support operator actions' identified during the sys-tem / task analysis effort. .
3.1.4 HED Assessment - This effort involves evaluation of the seriousness of potential HEDs and subsequent categoriza-tion according to safety significance.

This program'is managed by Plant Operations, with input from Pro-ject Engineering and Licensing as appropriate. Actual development of the emergency operating procedures is provided through the NSSS
, vendor and/or consultants as necessary. The Plant Manager pro-l vides the decision authority for acceptance of the Emergency Oper-ating Procedures, with reference 4.9 being used as an acceptance guideline.
. The effort is built upon the Emergency Guidelines developed by the
- Combustion Engineering Owners Group'(GE0G) - see reference 4.11.
WNP-3 specific guidelines are utilized to create the actual emer-gency procedures as well as support the System / Task Analysts ef-fort of the CRDR. Feedback from the CRDR Task Analysis effort is also used to assist in development of procedures.
The Emergency Operating Procedures are integrated into the Opera-tor Training Program as the procedures are developed and modified as a result of other TMI improvements programs. The CRDR Valida-
- tion Effort provides for demonstration of the adequacy of these.
f procedures.
3.4 Emergency Data System (EDS)
The objective of this program is to provide for a computer based, and optimally human engineered, graphic display of information im-1 portant to the safe shutdown of the power plant. References 4.3 and 4.7 are the pverning regulatory documents for this effort.
The EDS program is managed by Project Engineering, and heavily.
i supported by Plant Operations. The NSSS vendor (CE) provides the
, computer, peripherals, display development and supporting documen-tation with the Architect Engineer-(Ebasco) providing for integra-tion of the equipment into the plant. The Project Manager pro-vides the decision authority for acceptance of the EDS with refer-
~

~The EDS is based on the CE Critical Functions Monitoring System (CFMS) currently in use at Units 2 and 3 of the San Onofre Nuclear Generating Station.
3.5 Plant-Monitoring System (PMS) Program The objective of this program is to provide for a computer based and optima _11y human engineered, graphic display of information im-portant to the power production phase cf plant operations. While this system is not explicitly governed by post.TMI regulatory cri-teria, WNP-3 considers that enhancement of accident prevention techniques is an important part of the overall TMI improvements effort. The PMS is therefore included in the integrated effort.
The Plant Operations organization is responsible for display de-velopment control. Thewith Project NSSS vendorEng(ineering providing CE) provides the system for with design the interface Archi-tect Engineer (Ebasco) providing for integration into the plant.
Display development implementation is provided through the NSSS vendor, consultants and Plant Operations organization as neces-sary. The Plant Manager provides the decision authority for ac-ceptance of the PMS displays with the Project Manager accepting PMS hardware modifications.
Design information from the PMS program is utilized in the System /
Task Analysis portion of the CRDR Program and feedback loop from the HED Assessment and Plant Improvements portion of the CRDR pro-gram is used to enhance PMS displays. The PMS Program merges into the Training and Emergency / Operating Procedures efforts. Data from the Startup Test phase of the PMS Program is used in the CRDR verification of improvements effort. As previously noted, the-SPDS Program provides information to assist in development of con-sistent CRT displays.
3.6 Off-site Dose Assessment Program The objective of this program is to provide the plant with the capability to readily identify and project off-site radiation doses that may be attributable to accidents. This program'is governed primarily by reference 4.2, 4.7, 4.12 and 4.13.
The program is managed by the Supply System's Emergency Prepared-ness Organization with design interface control provided by Pro-ject Engineering. Tne Plant Manager provides the decision author-ity for acceptance of the Off-Site Dose Assessments Program with the Project Manager accepting plant modifications with reference 4.2 providing acceptance guidelines.
The intent of WNP-3 is to utilize the EDS to provide for off-site dose assessment. As such atmospheric model and sensor inputs are provided to the EDS design development effort. Alternate off-site REV. O Page 10 of 13
dose assessment concepts are also evaluated in order to ultimately provide the plant with a cost effective system consistent with established regulatory criteria.
3.7 Operating Procedures Program The objective of this program is to provide for operating proce-dures to assist operation of the power plant. While this effort is not explicitly governed by post TMI regulatory criteria, the Supply System considers that enhancement of accident prevention features is an important part of the TMI Improvement's Integration Effort. Accordingly, the Procedues Program is a part of the over-all integration effort.
This program is managed by Plant Operations, with input from Pro-ject Engineering and Licensing as appropriate. Actual development of operating procedures is provided through the NSSS vendor, Arch-itect Engineer, Plant Operations and/or consultants as necessary.
The Plant Manager provides the decision authority for acceptance of the operating procedures.
All the various hardware related programs (e.g., EDS, PMS, Post Accider' instruments, etc.) merge into the operating procedures effort cho. ugh the various technical / instruction manuals provided by the various vendors. The Architect Engineer and NSSS vendor as well as Project Engineering provide assistance in the proper uti'-
lization of the aforementioned information. Select operating pro-cedures will be used during the CROR Validation effort in order to demonstrate procedure adequacy.
3.8 Emergency Preparedness Program The objective of this program is to provide the necessary arrange-ments, directions and organizations to effectively resolve any plant emergency to ensure the safety of the general public and to safeguard plant personnel and property. References 4.3, 4.7 and 4.10 provide the primary regulatory guidance for this program.
The program is managed by the Supply System's Emergency Prepared-ness Organization with support as necessary by Plant Operations and the Project. The Plant Manager provides decision authority for acceptance of this program with reference 4.10 providing the acceptance criteria.
The WNP-3 Emergency Preparedness Plan is detailed by reference 4.12. As noted in this plan, a Technical Support Center (TSC) is used to provide a location for on-site technical assistance to the piant staff during emergency situations. Also, an Emergency Oper-( ations Facility (EOF) is provided for overall management of off-site responses. Both of these facilities employ extensive commun-ications and CRT displays driven by the EDS for information on l
l REV. 0 - Page 11 of 13 l
plant conditions as well as off-site dose projections and radio-active effluent monitoring. An off-site operations support center is also provided as the primary staging area for in-plant emer-gency recovery teams.
Emergency Plan Implementing Procedures are utilized to assist plant response to emergency situations with demonstration of pro-gram effectiveness is accomplished by drills leading to the WNP-3 emergency exercise which is observed and approved by the NRC and other cognizant regulatory organizations.
3.9 Operator Training Program The objective of this effort is to ensure that the plant staff re-ceives adequate training in order to support the safe and economic operation of the plant. TMI promulgated improvements are gener-ally identified in reference 4.3.
This program is managed by Plant Operations with input from Pro-ject Engineering and Licensing as appropriate. Actual training packages are developed by Plant Operations, the NSS vendor, Archi-tect Engineer and/or consultants as necessary. Specialized ad-vanced reactor training packages are provided through CE Owners Group (CE0G) activities. All the TMI improvements programs merge into the training program. The Plant Manager provides the deci-sion authority for acceptance of the Training Program.
