AFFIDAVIT OF C.
PAUL YUNDT COALITION FOR SAFE POWER'S CONTENTION NO. 17
~
1.
My name is C.
Paul Yundt.
I am employed by Portland General Electric Company (PGE) as General Manager of the Trojan Nuclear Plant.
I have been employed in this position since September 4, 19 T-My professional qualifications are contained in an attachment to this affidavit.
2.
I am responsible for safe conduct of operations, main-tenance and modification activities onsite at the Trojan Nuclear Plant.
Since my assignment as General Manager at Trojan, PGE personnel under my supervision have participated in review of the Trojan Control Building modification program described in the " Report on Design Modifications for the Trojan Control Building" (PGE-1020), and Licensee's responses to the numerous NRC Staff questions.
3.
The purpose of this affidavit is to address, in part, Cralition for Safe Power's Contention No. 17, which reads as folAews:
80031302.9
CFSP #17 Page 2 of 6 C.
P. Yundt Performance of modification work will hamper the ability of plant operators to respond to any emergency properly and thus poses an undue risk to the public health and safety.
4.
The plan for the modification program has been devel-oped to be compatible with Plant operations under both normal and emergency conditions.
The affidavit of Mr. Richard C.
Anderson on Coalition for Safe Power's Contention No. 17 identifies those areas where the modification work will be performed and also identifies potential interferences with access.
This affidavit will explain how PGE has identified all instances in which the modification work might interfere with the ability of Plant operators to respond to an emergency, including a fire, and will explain why the modification work will not cause such interferences.
5.
In order to respond properly to an emergency, Plant operators must be able to react to visual and audible signals provided by Control Room instrumentation.
In some cases per-sonnel may have to operate equipment from remote locations outside the Control Room, thus, access to such locations must be assured.
Therefore, proper response to any emergency re-quires that Plant personnel be able to function properly within the Control Room and to reach remote locations in other parts of the Plant.
6.
PGE has reviewed Mr. Anderson's affidavit and has deter-mined that it correctly idet.tifies all areas of the Plant where the modification work will be performed and all potential interferences with access by the modification work.
CFSP #17 Page 3 of 6 C.
P. Yundt 7.
In the event of a fire or other emergency within any of the areas where the modification work will be performed, Plant personnel would need access within such area.
Should such a fire or other emergency arise, modification work would be halted and construction workers would be instructed to leave the area and report to their supervisor outside the Plant buildings to await further instructions.
This will be part of the instruction given to workers on site for the modi-fication program, and the presence of these workers would not hamper the ability of Plant personnel to take effective action with respect to a fire or other emergency within such areas.
8.
PGE has also reviewed the modification work to ascer-tain whether there are any remote locations (as discussed in paragraph 5 above) within or adjacent to the work areas ident-ified in Mr. Anderson's affidavit to which Plant personnel may need access during an emergency.
The only such remote loca-tions are:
East Emergency Diesel Generator Room at el. 45' in the Turbine Building Engineered Safety Feature Switchgear Room at el. 69' in the Turbine Building Load Centers B12 and B06 (non-safety-related) at el.
69' in the Turbine Building Electrical Auxiliaries Room and Batteries at el. 61'/65' in the Control Building
CFSP #17 Page 4 of 6 C.
P. Yundt Visitors' Gallery at el. 103' in the Control Building */
9.
For each of the remote locations identified above, PGE has determined that at least one alternate access path is available which would be totally unobstructed by the modifica-tion work.
Accordingly, the modification work will not com-promise the ability of Plant personnel to reach such locations during an emergency.
10.
With respect to each of the specific instances identi-fled in paragraphs 6-8 of Mr. Anderson's affidavit where the modification work could involve potential interference with access paths, we have again determined that the modification work will not compromise the ability of Plant personnel to respond during an emergency, including a fire.
The limitation on access at el. 45' in the Turbine Building (Anderson affida-vit, paragraph 6) is not in an area where safety-related equip-ment is located and would not limit personnel access.
There is another existing access to the Visitor's Gallery, and as described in the affidavit of Mr. Anderson (paragraph 7) tem-porary alternate access will be provided to the Visitors' Gallery and the crane cab.
Finally, the potential interferences caused by workers in aisles (Anderson affidavit, pcragraph 7)
- /The Visitors' Gallery is currently designated to become the permanent location for a Technical Support Center to which technical support personnel would proceed to assist the operators during a Plant emergency.
The permanent Technical Support Center is scheduled to be operational by January 1, 1981.

- /The Visitors' Gallery is currently designated to become the permanent location for a Technical Support Center to which technical support personnel would proceed to assist the operators during a Plant emergency.

P. Yundt will be no greater than those one would expect during routine Plant maintenance.
Even so, as described above, should an emergency arise, including a fire, modification work will be halted and construction workers will be instructed to leave.
11.
Only a small portion of the modification work will take place at el. 93' in the Control Building adjacent to the Control Room.
If noise from work in this area interferes with operations, the Shift Supervisor or the NRC's Resident Inspector will halt the work and work methods will be changed to reduce noise to acceptable levels.
Additionally, a few construction workers will be required to be on the Control Room side of the walls during the drillirs; and bolting operations.
These individuals will be working away from areas requiring immedi-ate operator attention or action.
Furthermore, their presence and actions in this area will be controlled by the Shift Supervisor to preclude their inadvertently interfering with operations in the event of an emergency.
Thus, the modification work will not hamper the ability of operators in the Control Room to respond to an emergency.
12.
The foregoing discussion demonstrates that any poten-tial impacts of the modification work on the ability of Plant personnel to respond to an emergency, including a fire, have been identified, and that all necessary precautions will be taken to preclude any adverse impacts of the modification work on the ability of such personnel to respond properly.
