VIII.34-1 (EG96/lah)
APPLICABILITY NED personnel, including NED managed contract personnel who are involved in the control oE new design or modifications which affect safety-related equipment.
The purpose of this design guide is to establish the instructions necessary for consistent development and control of the Environmental Qualification Master List (EQML).
GENERAL A.
The EQML will become a controlled document, maintained by NED, and stored in the computer equipment data base system (EDBS) which is maintained by HPOS.
B.
Information Management Department (IMD) provides computer program control.
The EQML will be compiled directly from the EDBS.
C.
EDBS screen 408, Environmental Qualification Display, is used to designate the equipment qualification status of equipment where Y, H, J, K, M, or N designate equipment under the "Env" field on the 408 screen.
(See paragraph II.D.7 for definition of designators.)
D.
Definitions l.
~E ML The Shearon Harris Nuclear Power Plant EQML is a list of safety-related electrical equipment installed in a harsh environment, including interface materials such as splices,
- cables, heat shrink materials, and Regulatory Guide 1.97 instruments that require equipment qualification.
2.
Harsh Environment - An area where the environmental conditions change significantly during or after any anticipated operational occurrence including LOCA or main steam line break.
More specifically when:
a.
The temperature rises above ambient conditions by more than 10'C (18'F).
AND/OR b.
The total accumulated integrated radiation dose over a 40-year plus 1 year post accident period 4
exceeds 1 x 10 rads.
Equipment which contains sensitive semiconductors should be included to as low as 1 x 10 rads.
These areas are shown for the plant in Section 3.11.B of the SHNPP PSAR.

E ui ment uglification Data Packa e
(E DP) - An assemblage of environmental qualification data received from a vendor or generated by CP&L to document environmental qualification.
Documentation is to be completed in accordance with NED Design Guide DG-VIII.19.
4.
Electrical E ui ment - Electrical equipment which is physically independent and replaceable.
Examples are instruments, motor operators, motors> Limit switches, solenoid valves, and cables.
5.
Class 1E - Class 1E electrical equipment is designated by instrument tag numbers containing an SA, SB,
- SAB, I, II, III, or IV in the tag number or designat'ed as IGC Class Code N4 (by Regulatory Guide 1.97).

This relates to
- valves, equipment, or speciality item (tank).

E ui ment uglification Desi nator Y - Has electrical qualification requirements/not base lined.
N - Has no environmental qualification requirements.
H - Electrical equipment in a harsh environment/base lined.
N - Electrical equipment in a mild environment/base lined.
J - Has mechanical qualification requirements/not base lined.
K Has mechanical qualification requirements/base lined.
PROCEDURE A.
Principal Engineer Action 1.
Receives design change and assigns appropriate reviewers and cognizant engineers and provides appropriate guidance.
B.
