Subject:
Potential 10CFR50.55(e) Deficiency 55-84-07 Use of GE Non-Site Specific Design Specifications for CPS Application
Dear Mr. Keppler:
On March 28, 1984, Illinois Power notified Mr. F. Jablonski, US NRC, Region III (Ref: IP memorandum Y-20510, dated March 28, 1984) of a potentially reportable deficiency under the provisions of 10CFR50.55(e) pertaining to the possible use of General Electric generic versus plant specific design specifications in developing preoperational test procedures in use at Clinton Power Station (CPS).
This initial notification was followed by one (1) interim report (Ref: IP Letter U-10149, D. P. Hall to J.
G. Keppler, dated April 27, 1984).
Our investigation of this issue is progressing, and this letter is submitted as an interim report in accordance with the requirements of 10CFR50.55(e).
Statement of Potentially Reportable Deficiency Illinois Power Plant Operations identified a problem in determining specific General Electric design specifications applicable to CPS.
Illinois Power Startup staff use GE design specifications as a basis in writing CPS preoperational test procedures.
Use of GE documents not directly approved for CPS may have resulted in incomplete preoperational test procedures.
We are reviewing this concern for possible adverse impact on the safety of operation of CPS.

Background
Illinois Power. Plant Operations issued a Condition Report (I-83-03-067) on March 23, 1984, indicating that a roblem may-Drive-System Fast Scram," generic document 22A3899, p' exist with the use:of GE t
as a basis for writing a preoperational test: procedure (PTP-RD-07), whereas document 22A5395, specific to CPS,';should.have been used.
A GE reference listing of documents (CDCS) was used to determine applicable design specifications as a basis for the-test procedures.
Investigation Results Illinois ~ Power has prepared and implemented an investigation plan-to determine the extent of this problem at CPS.
The investigation plan included:
1.
A report was prepared by General Electric outlining the specific listing and means to determine the correct documents and instruction manuals applicable to CPS.
- 2. -
Procedures used by CPS staff to identify the correct controlled GE documents and instruction manuals, applicable to CPS, were reviewed to uncover any ambiguities in the selection of controlled documents for use in writing testing and other procedures.
3.-
Documentation control used for other than GE equipment was reviewed for similar problems in selecting controlled information.
Our investigation to date has determined that the primary root cause of the problem stems from some CPS personnel not being fully cognizant of the correct methods for determining GE documents that are specific to CPS.
The GE Manual - Engineering Documentation Systems, provides direction on how to use the GE documentation system.
The manual states that following issuance, the Master Parts List (MPL) becomes the principal working document for the CPS project, with respect to Tardware and software to be provided by GE.
The MPL is the top tier controlled document that references lower tier documents.
The MPL must be used to determine which documents are applicable to CPS.
The CDCS, by contrast, is a listing of the latest revision of each document transmitted to CPS from GE, regardless of the specific applicability to CPS.
The CDCS functions to provide an ongoing transmittal log of GE transmitted documents.
he GE Engineerina Information System (EIS) lists the latest revision of all documents directly applicable to CPS and those identified as references on these documents.
A
7 n.
L MrQ Jame3 G. Ktppler Peg 2 3 In summary, the MPL is used to determine which GE documents are applicable to CPS.
The EIS is used to determine the latest-document ~ revision.
" Corrective Action (Interim)
To date, the following corrective action is being taken:
1.
Training-is being conducted on the proper use of GE documentation.
Emphasis will be placed-on assuring
- that, CPS personnel are aware that the MPL' is the parent document to be used in determining applicable-GE documents.
'2.
Appropriate CPS procedures are being revised to specifically state _that the MPL should be used to determine appropriate GE documents.
3.
IP Test Procedure PTP-RD-07 is being revised to reference and agree with the correct design specification.
4.
A review of all issued test procedures is being performed to assure that the correct references were used.
.The test procedures will be revised where appropriate to correct identified discrepancies.
5.
An EIS terminal is being provided for use tar the Startup and Plant Operations Groups.
The EIS terminal-will provide on-line computer capability for determining the latest revision to GE documents.
6.
The Startup Library is being provided with a controlled copy of the MPL for use in determining applicable GE documents.
Safety Implications / Significance Illinois Power's investigation of this potentially reportable deficiency is continuing.
The safety implication and sipificance will be assessed after further background information is evaluated.
Approximately sixty (60) days will be rec uired to complete the investigation, determine reportability, anc' file a final report on this potentially reportable deficiency.
