Dear Mr. Denton:
Enclosed is information required for your review concerning Seismic and Dynamic Qualification of Equipment and Environmental Qualification of Equipment.
Some of this information was discussed with members of your staff.
Information Notice 86-02 The following test reports contain the qualification information for inside containment limitorques.

Information Notice 86-03 Rockbestos jumper ~ wires were qualified for internal use in limitorque operators.
This is the qualified wire mentioned per reference (a).
1 Mechanical Environmental Equipment Unique to Braidwood In reference (b) we reported that valve 2RY8000A was the only safety-related active mechanical component located in a harsh environment for components unique to Braidwood.
Based on an informational update this Borg Wagner valve, as previously 1
identified for use on 2RY8000A, is serving as a spare.
A l
Westinghouse valve was installed instead and is the same type as the i
others.
Page 101 of 165 of the attached SQRT document reflects this change.
Therefore, there are no unique safety-related active j
mechanical components in harsh environments located at Braidwood Station.
Conformance to EO Rule f
In order to address the requirements of the environmental
{
qualification of Class lE electrical equipment for the Byron and Braidwood Nuclear Stations-Units 1 and 2, the Commonwealth Edison Company has instituted an Environmental Qualification Program which establishes the qualification of all Class 1E electrical equipment in harsh areas.
The equipment covered by this program includes all j
electrical equipment required for emergency reactor shutdown, j
containment isolation, renctor core cooling, containment heat
[
i removal, core residual heat removal, or prevention of significant i
i release of radioactive material to the environment.
{
Nonsafety-related components located in harsh areas, whose failure could adversely impact the function of safety-related components is included in the E.Q. program.
i The E.Q. program is designed to identify all harsh Class lE l
equipment and to summarize the qualification status of all Class 1E l
equipment located inside the containment and Class 1E equipment located outside the containment which may be subjected to a harsh environment.
A harsh environment is defined as any area which will experience a significant change in one or more of the environmental parameters as a result of an accident.
The harsh environments j
result from Loss-of-Coolant-Accident (LOCA)/ Main Steam Line Break j
(MSLB)/High-Energy Line Break (HELB) inside the containment, MSLB j
outside the containment in the main steam piping tunnel, and the i
HELB outside the containment.
The review included the effects of radiation on equipment located outside of the containment building during post-LOCA recirculation of containment sump fluids.
i Installed RG 1.97, Category 1 and 2 instrumentation located in a j
harsh environment is also included in the qualification program.
i
a
' The review of environmental qualification documentation was performed by qualified personnel collectively experienced in all i
aspects of the design and operation of a nuclear generating station.
The development of the environmental conditions was based on the guidelines provided in NUREG-0737 and NUREG-0588 for Category I plants.
A critical review of all environmental qualification documentation was conducted to determine whether all of the requirements of IEEE 323-1974 were met.
The environmental qualification review evaluated each l
specific piece of Class lE equipment to determine whether the environmental conditions applicable to the equipment's location were enveloped by the conditions to which the equipment is qualified.
The review of the environmental qualification documentation was documented on review checklists which address each of the requirements of IEEE 323-1974 and NUREG-0588.
Supporting qualification documents are available in a dedicated environmental equipment qualification file.
Basad on this review process, Commonwealth Edison believes that the requirements of 10CFR50.49 are being met.
However, it is important to point out that the EQ program is dynamic.
During the j
life of the plant changes will be required.
These changes will be controlled and implemented by procedures which incorporate E.Q.
requirements, l
i Seismic and Dynamic Qualification I
In reference (b) we reported that the Welman Model #44C675 control circulation heaters were now seismically qualified.
The seismic load input data and other information is now provided as shown on page 140 of 165 the attached SQRT document.
