I.A.1.3 SHIFT MANNING Technical Specifications, Section 6.2.2, for both North Anna Units 1 and 2 require a minimum shift crew and overtime restrictions in accordance with the requirements of I.A.1.3.
Administrative procedures have been revised at Surry Units 1 and 2 to limit overtime in accordance with these requirements.
In addition, a request to change Technical Specifications was submitted on November 14, 1980, which would specify a minimum shift crew consistent with the requirements on page I. A.1.3-4.
I.A.1.3-11
I. A. 2.1 IMMEDIATE UPGRAD_ING OF REACTOR OPERATOR AND SENIOR REACTOR OPERATOR TRANING AND QUALIFICATIONS The upgraded requirements for senior reactor operator license applicants have been implemented effective December 1, 1980.
The experience of ea.ch appli-cant is checked by the station Supervisor - Nuclear Training against the criteria in this section.
The previous requirement that applicants for SRO licenses have 4 years of responsible power plant experience, of which at least 2 years shall be nuclear power plant experience (including 6 months at the specific plant) and no more than 2 years shall be academic or related technical training, has also been implemented.
Current applicants for licenses are certified to be competent by the Executive Vice President - Power.
The training _program for SRO/RO candidates includes training in heat transfer, fluid flow, thermodynamics, and plant transients.
I.A.2.1-21
I.C.l GUIDANCE FOR THE EVALUATION AND DEVELOPMENT OF PROCEDURES FOR TRANSIENTS AND ACCIDENTS On December 15, 1980, the Westinghouse Owners Group submitted a detailed description of a program to comply with the requirements of I. C.1 for both Inadequate Core Cooling and Transients and Accidents (Ref:
Letter No.
OG-47).
The submittal id~ntified previous Owners Group submittals to the NRC, which are believed to comprise the bulk of the required information.
Additional effort required to obtain full compliance with Item I. C.1 ( with a proposed schedule for completion) was also identified.
Additionally, on March 18, 1981, an update of the status of the Owners Group I. C.1 activities was submitted to the NRC (Ref:
Letter No. OG-54).
This approach was discussed during a November 12, 1980 meeting between Westinghouse Owners Group representatives at the NRC Staff, and is consistent with the alternate requirements on page I. C.1-4.
The NRC review of the Westinghouse Owners Group proposed program ( OG-54) identified several staff concerns.
These concerns were outlined in letters from Mr. Robert A-. Clark (dated June 9, 1981 for North Anna) and Mr. Steven A. Varga (dated June 10, 1981 for Surry) to Mr. J. H. Ferguson. of Vepco.
In response, the Westinghouse Owners Group evaluated and revised its proce-dures development program and forwarded to the NRC a revised program on July 7, 1981 by letter from Mr. R.
- W. Jurgenson ( AEP, Owners Group Chair-man) to Mr. S. H. Hanauer of the NRC (Ref:
Letter No. OG-61).
This revised prgoram was received and considered acceptable by the NRC.
NRC acceptance of the Owners Group revised program is documented in a letter from Mr.. D, G. Eisenhut to Mr. R. W. Jurgenson dated September 18, 19Sl.

I.C.5 PROCEDURES FOR FEEDBACK OF OPERATING EXPERIENCE TO PLANT STAFF The operating experience assessment function has been implemented through both a system-level Safety Engineering and Control group and Safety Engineer-ing staffs at each station.
Procedures for the operation of the system organization, the North Anna SES and the Surry SES were in effect prior to January 1, 1981.

North Anna Units 1
& 2 control room has been reviewed and modified-- to reflect the human engineering recommendations of the NRC presented in the
_ Essex Corporation Report. Surry Units 1 & 2 control room has been reviewed to establish short-term improvements.
One of these improvement modifications will be made on Unit 2 during the Fall 1981 refueling outage and is scheduled for the Spring 1982 maintenance outage on Unit 1.
Other modifications will be evaluated using mock-ups on the simulator prior to implementation in the Control Room.
I.D.1-4 2
1.D.1 CONTROL ROOM DESIGN REVIEWS - EXCEPTIONS In September 1981, the NRC issued the "interim requirements" (NUREG 0700) for the control room design review.
Vepco is concerned that the present "interim requirements" may be superseded by later final requirements that would adversely affect Vepco resource commitments.
Until the NRC issues specific schedule requirements on the subject, Vepco will initiate only a minor effort at this time in response to NU REG 0700.
I. D.1-5 2
II. B.1 REACTOR COOLANT SYSTEM VENTS - EXCEPTIONS At the present time, priority is being given to the development of the North Anna Unit 1 final design to support the implementation of the vent systems during the* refueling outage scheduled to begin January 1, 1981.
The electri-cal schematics providing qualified valve cable entry seals are not yet complete.
After the North Anna Unit's electrical schematics have been finalized, emphasis will be put on the electrical schematics for Surry Unit 1.
As a consequence, we do not expect to have all the electrical schematics for all units by the required documentation date of July 1, 1981.
However, the schematics will be similar and will be provided for the individual units as soon as they become available.
Vepco will* not be able to support complete documentation of the test and operating procedures and supporting analysis as required by Position 2 and document item (3) by the required date of July 1, 1981.
This information will be developed as the RCS vent and reactor vessel level system designs are developed and the systems are installed.
The information should be available by January 1, 1982 to allow NRC review prior to implementation of the systems.
By. July 1, 1982, Vepco intends to provide a list of vent system components (valves, cable, connections, etc.) and a description of the test programs that have been or will be performed to demonstrate compliance with NRC's order of May 27, 1980.
The availability of_ this information cannot be assured at this time because the vent system components are under various stages of procure-ment.
Installation of the RCS vent system connection requires removal of the reactor vessel head.
Vepco proposes to install this portion of the system during refueling outages.
As shown in Section C, the next refueling outage for North Anna 2 and Surry 2 are currently scheduled for the first half of 1982.
Those dates would support inst~.llation of the system lJy July 1, 1982.
How-ever, any unscheduled outages could extend the refueling beyond the required installation date.
Therefore, Vepco requests a change to the required instal-lation date for the RCS Vent System to be July 1, 1982 or the first refueling outage after January 1, 1981, which ever is later
- II.B.1-10
- 1.
The majority of electrical equipment in these systems are not quali-fied to meet the integrated radiation dose to which they would be exposed in processing and concentrating the highly radioactive water or gas.
- 2.
There is extensive piping for the recovery systems throughout the auxiliary building.
The resulting dose rate from all these systems operating simultaneously would severely limit access for the required operation.
Shielding for the. recovery system piping and components would be very difficult and in some cases may be impossible to install due to the arrangement of the piping and equipment.
B.
Modifications - Shielding or Equipment Changes for Reduction of Personnel Exposure As a result of the plant radiation and shielding review, we have identi-fied additional shielding and plant modifications to reduce the personnel exposure and equipment irradiation qualification required by NUREG 0578 which is more conservative than subsequent clarifications (NUREG 0737 allows the shielding to be based on a 30-day average base).
North Anna Only
- 1.
- 2.
The post-accident hydrogen recombiner vault requires shielding modifications to limit radiation exposure to the operators at the vault while realjgning and operating the recombiner, and to reduce the levels in the continuous occupancy areas.
Manual valves, located in high radiation zones, which must be operated to line up and operate the post-accident hydrogen recom-biner and hydrogen analyzer will be replaced with environmentally qualified remotely operated valves,
- such as direct-acting solenoid valve or air-operated valves.
Surry Only
- 1.
In order to automatically adjust cooling water temperature to charg-ing pumps, automatic temperature control valves are being added to the service water lines in the charging pump cooling water subsystem.
- 2.
Manual valves, located in high radiation zones, which must be operated to line up and operate the post-accident hydrogen analyzer will be replaced with environmentally qualified remotely operated valves, such as direct-acting solenoid valve or air-operated valves.
North Anna and Surry
- 1.
Shielding of portions of the lines added as part of the new post-accident sampling system may be required.

- Al though no access is required in the lower level auxiliary building or safeguards* building to mitigate an accident, the drain system for the auxiliary building sump and the safeguards building sump is being studied for modification so that these sumps can be pumped to the affected unit's containment instead of to the high or low level waste tanks.
This would eliminate a significant potential source of activity in the basement of the auxiliary building.
- 4.
Sampling procedures have been modified and temporary shielding employed to limit dose rates at the present sample facility.
- 5.
- 6.
Additional shielding, area relocation, or procedural modifications are being evaluated to limit radiation dose rates in the technical support center, the operational support center, the counting lab, and the security control center.
System modifications to pe~init interfacing with external process systems to be designed and shielded after the accident are being made.
The external process system design would be based on the extent of the accident and would utilize the most current technology available at the time of the accident.
Modifications - Equipment Qualification The evaluation. of radiation environmental qualification of equipment is proceeding slowly because of the difficulty in obtaining vendor data on older plants.
The mechanical equipment review for LOCA is complete for North Anna and Surry.
Vepco has reported the results of the electrical equipment review in conjunction with the responses to I.E. Bulletin 79-0lB.
Any necessary modifications will be made !iS material becomes available.
In addition, Vepco has concluded its review of the radiation effects on mechanical equipment required to mitigate a high energy line break
( HELB) for North Anna and Surry Power Stations.
This review indicates that no equipment modifications are required to mitigate the HELB tran-sient.
Replacement of, or shielding for, material with insufficient radiation resistance in the following equipment has been identified to date and is in progress as noted.
See Section C for proposed installation scheduled.
These materials meet the requirements of the FSAR but not the extended requirements of NUREG 0578, NUREG 0660, NUREG 0737 and IE Bulletin 79-0lB.

D.
Additional Information The basis for systems excluded:
- 1.
The design of the Reactor Coolant System (RCS) and supporting systems is s1:1ch that the letdown portion of the Chemical and Volume Control System (CVCS) is not required to take the plant to a safe shutdown (hot standby) condition or mitigate the effects of a LOCA.
The use of the eves letdown could create significant radiological problems.
The letdown portion of the CSVS was not considered in this review for the following detailed reasons.
At TMI,-2, high airborne activity levels and high radiation levels outside the containment resulted from using systems which carry highly radioactive fluids from inside the containment to other build-ings.
One of the lessons learned from TMI-2 is to isolate from the containment all nonessential systems.
This is also a requirement of NUREG 0737, Section 11.E.4.2.
The letdown and normal charging portions of the eves is automatically isolated by the phase A con-tainment isolation signal.
Use of the letdown portion of the eves presents the potential for increasing activity levels outside the containment.
This portion of the eves is not required to mitigate an accident and this is kept isolated from the containment.
II. B. 2-13 1 2 I* l
- 3.
The Boron Recovery, Liquid Waste, Solid Waste, and Gaseous Waste systems were not considered in the shieldmg review for the following reasons:
- a.
These systems were not designed or arranged to accommodate the activity levels that could be present after an accident, but rather to operate at the design conditions of one percent failed fuel as discussed in FSAR Section 11.
The calculated activity concentration based on Regulatory Guide 1. 4 and TID-14844 of the influent to the Liquid Waste or Boron Recovery system is approximately 2000 uci/cc, even after six months of radioactive decay.
Thus, concentrated effluent in the evaporators of these systems would be so highly radioactive that shielding, processing and handling of the waste by conventional methods would not be possible.
The area radiation dose rate from the concentrated waste and storage tanks would severely limit access to parts of the Auxiliary Building.
It is proposed to keep this waste inside containment until the recovery phase when cleanup operations begin.
- b.
Modifications are being designed to add connections to these and other systems to permit interfacing with an external waste processing system specifically selected for post-accident clean-up, during the recovery phase, of radioactive fluids and gases resulting from the accident.
Inclusion of all essential sources in the review:
All essential system piping and equipment required to mitigate the effects of a LOCA which contain or could contain highly radioactive fluids were considered as sources in our shielding review.
These systems include; the High Head Safety Injection (HHS!) portions of the CVCS and SI Systems, the Low Head Safety Injection (LHSI) System, Recirculation Spray System, Sample System, and Containment Atmosphere Cleanup (hydrogen recombiner) System.
In addition, other systems which are not required to mitigate a LOCA and are not required by NUREG 0737, but which could contain significant radioactivity, were considered such as drain lines and standing water in sumps and waste tanks.
All branch connections to and from these systems were considered as sources to the first isolation valve.
Other sources such as the shine from the contain-ment dome, shine through containment penetrations, and shine through the personnel hatch were considered.
The locapon of field run pipe, which is part of the systems listed above, was considered in our analysis.
As noted in the response to the North Anna FSAR Comment 12.3, the routing and location of radioactive piping is such that the piping is in shielded areas.
The exact routing of our field run pipe is not critical in the production of the radiation zone maps.
The highest activity level in each zone is calculated and that level is considered for the entire zone.
For instance, the highest activity may be 12 inches from a pipe, regardless of its exact location within the zone.
II. B. 2-15
Indirect radiation was not considered as a source.
Buildup factors in shield walls are considered but scatter over walls or through labyrinth doorways was not considered.
Airborne activity was not considered as a source in our shielding review.
Consideration of all vital areas:
Vital areas for personnel exposure are defined as those areas which re-quire continuous or frequent occupancy in order to control, monitor, and evaluate the accident.
These areas include the Control Room, Technical Support Center, the Counting Lab/Health Physics area, the Operational Support Center, and Security Control Center.
In addition, any area which requires access to perform manual operation of equipment in systems which are used to mitigate the accident were considered.
Vital areas for equipment qualification inlcude all areas in which mitigating equipment is located.
Zone maps have been developed for many non-vital areas. as well.
These areas include the entire Auxiliary Building, Main Steam Valve House, Quench Spray Pump House, Safeguards Building, Service Building, and selected areas in the yard.

Post-Accident Sampling Modification The interim modifications made to the sampling system and the pro-posed long term modifications are designed to minimize the exposure to personnel during sampling using time, distance and shielding.
Shielding-for portions of the interim sampling system lines has been installed.
Shielding for portions of the long term post-accident sampling system lines and the sampling facility is required.
Technical Support Center Sufficient shielding will be designed into the technical support center to limit personnel exposure to acceptable levels.
Operations Support Center (North Anna)
The Operations Support Center at North Anna will be located in an area with acceptable radiation dose rates.
Counting Laboratory Shielding for some instruments in the counting laboratory or reloca-tion of the counting equipment is necessary due to background activities.*
Hydrogen Recombiner Modifications (North Anna Only)
The hydrogen recombiner system at North Anna is external to the containment.
Because of the potential for a large dose contribution after post-accident operation modifications are being made.
The vault will be modified to provide a monitored release path for leakage from the hydrogen recombiner system to the Auxiliary ventilation system.
II. B. 2-16
r
- f.
The post-accident hydrogen recombiner vault requires shielding modifications to limit radiation exposure to the operators at the vault while realigning and operating the recombiner and to reduce the levels in some of the vital areas.
Relocation of the recombiner control panel is also required.
Containment Atmosphere Cleanup System Manual valves, located in high radiation zones, which must be operated to line up and operate the post-accident recombiner at North Anna, and hydrogen analyzer, will be replaced with environ-mentally qualified, remote op~rated valves.
Also, for more reliable system operation, dedicated penetrations will be provided for both of the H2 analyzers.
Section II.E.4.1 shows the proposed modifications in the valve arrangement for the containment atmosphere cleanup system.
These modifications provide a double valve barrier between the accident unit's containment atmosphere which is being processed by either hydrogen recombiner, all other systems, and the unaffected contain-ment.
Remote operators will be provided for those valves where personnel access is restricted by post accident radiation levels.
In the case of the containment purge blowers, an additional manual isolation valve is being installed to isolate this system from the Containment Atmosphere Cleanup System.
This valve will not be remotely operated.
Since use of the purge blower system is not considered to be requir~d in the mitigation phase of an accident, this system would be used as a back-up to the redundant H2 recombiners only if the containment atmosphere were acceptable for release.
- g.
Security Control Center The emergency procedures will be revised to incorporate instruction on relocation of the security boundary if radiation doses in the yard_ are not acceptable.
In addition, Vepco has committed to implementation of the following modifications at North Anna Units 1 & 2 and Surry Units 1 & 2.
These modifications are not required to validate the results of the shielding review or satisfy the requirements of NUREG 0578 but would reduce personnel exposure during the Recovery Phase.

- equipment will be done in accordance with the guidelines and schedule set forth in I.E. Bulletin 79-01B.
The installation is scheduled for the first refueling after Summer 1982.
(Surry only) 2c.
Delivery for control valves required to automatically adjust service water to the charging pump lube oil cooler has been delayed due to a labor strike since July 19, 1981, at the vendors manufacturing plant.
The vendor has promised valve delivery in November, 1981 and should the vendor deliver the valves in November, Vepco will be able to schedule to install the valves by no later than July 1, 1982.
( Surry only) 2d.
Due to material delivery problems, the modifications :Scheduled for the hydrogen Recombiner Vault and Service Water Radiation Monitor (shield-ing) will be delayed beyond January 1, 1982.
Vepco will have these modifications completed by April 1, 1982.
(North Anna only).
2e.
Due to manufacturing problems at the vendor, the modifications to replace the teflon material on the Low Head Safety Injection & Recirculation Spray Pump Restraints will be delayed beyond January 1, 1982.
- However, Vepco will make the material replacement by April 1, 1982.
(North Anna only)
- 3.
The radiation zone maps for personnel access will be revised after all the post-TM! modifications are complete to ensure the impact of all changes are incorporated.
This revision will take a few months and will replace the radiation zone maps prepared by January 1, 1980 that identified the required modifications for personnel access.

II.B.3 POST-ACCIDENT SAMPLING SYSTEM - EXCEPTIONS A.
The exceptions for the containment atmospheric sample system are as follows:
B.
- 1.
North Anna Unit 1 shall have a temporary sample return line to the existing Hydrogen Analyzer lines.
The temporary return line will be used until the permanent Hydrogen Analyzer returns are installed by 7-1-82.
The Containment Atmospheric Sampling System supply lines for North Anna Unit 1 and Surry Unit 2 will be heat traced after 1-1-82.
- 2.
North Anna Unit 2 and Surry Unit 1 will utilize the Short-Term Post-Accident Sampling System connected to existing Hydrogen Analyzer tubing.
The temporarily installed Short-Term Containment Atmospheric Sampling System supply tubing will not be heat traced.
The permanent supply and return lines to the Containment Atmos-pheric Sampling Panel will be installed at the respective first scheduled unit outages after 1-1-82.
- 3.
QA Category I control switches for the containment isolation valves for Containment Atmospheric Sampling System are not available prior to 1-1-82.
QA Category II control switches will temporarily be installed until the QA Category I control switches are available.
The Exceptions for the Reactor Coolant Sampling System:
The Sentry Equipment Company Chemical Analysis Panels ( CAP) and Chemical Analysis Monitor Panels (CAMP) were originally scheduled for delivery in December, 1980.
Vendor delays have resulted in delivery in late October, 1981 to North Anna. and Surry Power Stations.
Because of this late delivery, the installation of mechanical and electrical tie-ins, as well as system testing, must be accomplished in an extremely short time frame.
- However, Reactor Coolant Sampling Syste,m installation will be completed by 1-1-82 except system testing which will be expedited.
Vepco will have the Reactor Coolant Sampling System fully operable by 7-1-82.
During that period, the Short-Term Sampling System will be utilized.

II.D.1 PERF'.ORMANCE TESTING OF POWER RELIEF VALVE AND SAFETY VALVES As a sponsor of the EPRI PWR Safety and Relief Valve Test Program, Vepco intends to comply with the requirements of NU REG. 0578, Item 2.1. 2.
By letter dated December 15, 1980, R. C. Youngdahl of Consumers Power Company has provided the current PWR*Utilities' positions of NUREG 0737, Item II.D.1 clarifications.
Briefly, those positions are:
A.
Safe.ty and Relief Valves and Piping - the EPRI "Program Plan for Per-formance Testing of PWR Safety and Relief Valves", Revision 1, dated July 1, 1980, does provide a program that satisifes the NRC requirements.
Discussion with the NRC staff and their consultants are resolving specific detailed issues.
B.
Block Valves - The EPRI Program has not formally included the testing of block valves.
However, a small number of block valves have been tested at the Marshall Steam Station Test Facility.
By letter dated July 24, 1981, Mr. R. C. Youndahl of Consumers Power Company has provided the current PWR utilities position on Block Valve testing.
C.
A TWS Testing - PWR Utilities will not support additional efforts for A TWS valve testing until regulatory issues are resolved.
The major safety and relief valve test facility ( CE) is nearing completion and some measures were taken to provide additional test capability beyond the current program requirements.
The NRC should recognize that results from the current program are likely to provide most of the information necessary to address ATWS events (i.e.*, relief capability at high pressure).
