4.0 PROCEDURE REQUIREf1ENTS 4.1  !!DDs consists of two parts and are used for describing modifica-tions and new construction requirements.

4.1.1 -Division I defines the criteria and is prepared during I the conceptual phase of design.

4.1.2 Division II documents the actual design and is prepared during the detail design phase. A preliminary version of ifDD II is required for the Preliminary Engineering Design Review. (Ref. 5000-Adit-7311.03 [EltP 014]) This version also provides information to the Training departments for lesson plan development and/or revision.

4.2 SDD's have under a single cover the elenents described above for the f100 Div's I & II. They are system oriented and intended for use by naintenance and operations purposes by Technical Functions and the Plant. flot many such documents currently exist for GPUtlC plants except as described in the note of section 3.1. flo criteria has been established for determining when a SDD must be prepared except for situations when nodifications address completely new systens in total. SDD's are then prepared.

4.3 The requironent for either a DIV I or DIV II can only be waived by a Director from the organization responsible for the activ-ity. Decisions on waivers shall consider how design criteria are to be documented. Uaivers shall be documented by a memo to file in ED&CC.

4.4 DIV I and II cocbined nust provide sufficient source or back-ground information from which operation and maintenance training naterials can be generated.

4.5 ftDDs am. SDDs shall contain a cover sheet as shown in Exhibit 2.

4.5.1 Cover sheets shall be carked "If1PORTAtlT TO SAFETY," and "flVCLEAR SAFETY RELATED" when applicable.

er SDD's shall be revised as necessary, narked "AS-BUILT"

on the cover and released as "As-Built" (Ref.

The appro-priate system number shall be selected from ES-017, 4.6.1 Each !!DD related to one systen shall be assigned a letter identifier in alphabetical sequence. Only one SDD may exist for any one system.

4.8 ftDD I - Criteria for Use 4.8.1 A flodification Design Description I is a required docu- 1, l ment for a plant modification governed by Technical Func-l tion procedures (see Paragraph 4.3 regarding waivers).  !

It is prepared during the conceptual phase of a modifica-tion. The DIV I plus a preliminary DIV II provides an i early description of the modification, for use by reviewers, in assessing the extent of change, the viability of the design, etc., and shall be completed and issued prior to start of construction. DIV I and a preliminary version of the DIV II shall be included as part of the documents for the Preliminary Engineering Design Review (PEDR) (Ref. 5000-Adit-7311.03 [Ei!P-014]).

l In cases where an 500 for the entire systen has been previously issued, the i1DD I and Preliminary ?!DD II may I be used to update the system SDD at the completion of the g modification.

What will this system / modification do? Do not mix in design requirements.

4.9.5 DESIGN REQUIREffEllTS - The subsections which follow ident-ify the specific functional and design requirements to be I satisfied by the system. These criteria should be in accordance with the overall plant technical requirements. I

• The technical or licensing bases for each requirement I must be stated unless it is clearly obvious. In many cases the basis for the requirement can be deferred by specifically referencing a source document such as a Technical Data Report, Code, Standard, SAR or a related if00 or 500. In case of lengthy documents such as the SAR or the ASifE R&PV code or standard a specific section or paragraph should be referenced.

• The information given should be specific, definitive, and concise; generalizations and platitudes are not appropriate (e.g., that the system is to be "reifable" I

or " safe"). These requirements should be presented as l

" punchy" statements (all "shall, should, may" state-ments). They must be a complete set of design criteria l ,

but should not be repetitive. The following subsec-

' tions (e.g. a-1) shall be included. The order of these subsections may be changed and other subsections may be added to completely characterize a particular system /

modification.

I Appendix R 10-CFR-50 (Sections IIIG, IIIJ & IIIO) l must_be considered. If the design impacts fire j safety the design must satisfy Appendix R requirements. If the design does not impact Appendix R, this fact must be stated.

Environmental qualification requirements shall be addressed in this section, n fl0TE: Without documentation of the technical basis, it I is impossible to fulfill the requirement of ANSI fl45.2.11 R to which the GPUN Operational 0A Plan commits compli-j ance. ANSI requires that the design documentation 3; include a record of the source of design inputs. For 21 future nodifications the design engineer nust know the 3l complete basis for the previous design.

\ EXHIBIT 4 Human Factors Design Activities j

A human factors (HF) analysis is required for any new system or system modification involving a can-machine interface (MMI).

^

l!!!I: An 11MI exists anywhere a human operator becomes involved with compon-ents in the system. This may range from a door to be opened (can the door be safely and easily used by all operators during all probable conditions) to complex control panel design.

As part of HF design activities full scale nock-ups of the system are generally used, with walk-throughs for design operations and human factors staff. The systen is not built until the mock-up and applicable drawings have been evaluated.

For the design to be acceptable from a hunan factors standpoint, it cust comply not only with the generally accepted hunan factors standards, but also with the specific conventions in use at the facility being nodified.

j The HF analysis of a systen generally includes the following elements:

I. Controis and Displays

A. Type (acceptable with HF principles and in accordance with site i conventions)

B. Location of pane 1(s)

C. Arrangenent of controls on pane 1(s) l II. Anthroponetry and' Accessibility A. Anthroponetry (hunan size and physical abilities)

1. Workplace layout

2. Panel design B. ACCes s

flodification and System Design Descriptions 1-00 EXHIBIT 5 Guidelines for Changes flot Requiring QA Contact 1

This exhibit provides guidance concerning when to obtain QA review of changes  !

to previously released documents that contain QA concurrence.

)

QA review is requireif any time the quality or inspectability requirements in the design documents are affected. The tern inspectability neans the physical l ability to verify installation in accordance with the specified quality requirements.

QA Engineering notification of the type of changes listed below is not required; for all other changes to documents that contain QA concurrence, QA Engineering review is nandatory.

1. Ifode of plant (startup, operating procedures, etc.), equipnent (associ-ated with plant mode) alignment (valve / pump /switchgear, etc.), or other prerequisite changes.

2. ifaterial type or grade changes. (flew material must not be of a con-l trolled or prohibited category.)

l 3. Change of shape (inspectability cannot be affected).

4. Administrative changes, typo etc. that have no bearing in technical I content

{

5. Resolution of interferences expressing only a spatial (routing) prefer-ence (e.g., east or west side of columns) when no additional work (such as additional penetrations) is authorized.

6. Equipment designators or naneplate/ tagging requirements are changed.

! 7. Acceptance values of test parameters (e.g., voltage, hydro pressure, l' compressive strength) change within code requirements, but method of testing remains the sane.
