993754-AFF-36T AFFIDAVIT No. 993754-AFF-36T Re: Request for Withholding from Public Disclosure per 10CFR2.390 STATE OF CALIFORNIA ss COUNTY OF ORANGE I, Roman Shaffer, being duly sworn, hereby say and depose: 1. I am the Diablo Canyon PPS Replacement Project Manager for Invensys Operations Management, and as such I have been specifically delegated the function of reviewing company proprietary information sought to be withheld from public disclosure in connection with nuclear IE qualification and application of the TRICON Programmable Logic Controller (PLC) and am authorized to apply for its withholding on behalf of the Nuclear Delivery Unit of Invensys Operations Management.
- 2. The information sought to be withheld is contained in the document(s) described below: (1) Maximum TSAP Scan Time, 993754-1-817, Rev 1 The indicated document contains information considered to be proprietary.
Proprietary material in the enclosed document is indicated by brackets [ ] or other similar markings as required by IOCFR2.390(b)(1)(i)(B).
A Non-proprietary version of the document is not being provided, due to the predominantly proprietary content. This information is associated with the Diablo Canyon Power Plant (DCPP) Process Protection System Replacement Project, which incorporates Invensys Operations Management TRICON systems and delegated digital application project integration services.
This will allow the NRC to verify compliance with current regulatory requirements for certain Invensys Operations Management activities in support of the DCPP PPS Replacement Project. 3. I am making this affidavit in confonnance with the provisions of I OCFR Part 2.390 of the Commission's regulations and in conjunction with the Invensys Operations Management application for withholding accompanying this affidavit.
- 4. I have personal knowledge of the criteria and procedures utilized by the Nuclear Delivery Unit of Invensys Operations Management in designating information as a trade secret, privileged, or as confidential commercial or financial information.
Some examples of categories of information which fit into the definition of proprietary infonnation are: a) Information which discloses process, method, or apparatus, including supporting data and analyses, where prevention of its use by Invensys Operations Management's competitors without license or contract from Invensys constitutes a competitive economic advantage over other companies in the industry.
b) Information, which if used by competitors, would reduce their expenditure of resources or improve their competitive position in the design, manufacture, shipment, application, installation, assurance of quality, or licensing of a similar product. c) Information which reveals cost or price information, production capacities, budget levels, or commercial strategies of Invensys Operations Management, its customers, its partners, or its suppliers.
Page 1 of3 993754-AFF-36T d) Information which reveals aspects of past, present, or future Invensys Operation Management customer-funded development plans or programs, of potential commercial value to Invensys.
e) Information which discloses patentable subject matter for which it may be desirable to obtain patent protection.
t) Information obtained through Invensys Operation Management actions which could reveal additional insights into nuclear equipment qualification processes, customer applications, and regulatory proceedings, and which are not otherwise readily obtainable by a competitor.
Information to be withheld is considered to be proprietary based on 10CFR2.390(a)(4), with consideration of the reasons set forth above. 5. This document describes the details ofa program to qualify Invensys Triconex equipment for IE application, product design details, and/or customer application approaches.
Invensys Triconex is the first manufacturer ofa PLC to fully implement the requirements set forth in the EPRI TR-I07330, which has been endorsed by the Commission in an SER. Invensys Triconex has expended a significant amount of money and effort involving numerous contractors over a 10 year time period to develop and implement an ongoing successful approach to its test programs and nuclear applications.
Information developed relating to test plans, approaches, equipment, specific problems encountered, licensing perspectives, application approaches, and lessons learned has significant value because of the resources expended to successfully accomplish this process and the usefulness of this knowledge to potential competitors.
Specific data showing compliance with requirements and demonstrating technical capability of the equipment has substantial commercial value because it provides the basis for qualifying Invensys Triconex equipment and implementing safety-related digital upgrades to nuclear plants. Existing options for digital upgrades in the nuclear industry are limited. We believe that ongoing successful 1 E qualification upgrades of the TRICON PLC products and implementation of plant application projects will continue to give Invensys Operations Management a competitive advantage in this field. Disclosure of information in these documents would cause substantial harm to the competitive position of the Invensys Operations Management, as there are other competing companies who wish to qualify digital PLC controllers and apply them in safety related applications in nuclear power plants. Competing firms could use our experience, successful approaches, and technical information to facilitate their own equipment qualification efforts, application approaches, and/or product design without compensating Invensys Operations Management.
- 6. Pursuant to the provisions of paragraph (b)( 4) of Section 2.390 of the Commission's regulations, the following is furnished for consideration by the Commission in determining whether the information sought to be withheld from public disclosure should be withheld. (i) The information sought to be withheld from public disclosure is owned and has been held in confidence by Invensys Operations Management. (ii) The information is of a type customarily held in confidence by Invensys Operations Management and not customarily disclosed to the public. Invensys Operations Management has a rational basis for determining the types of information customarily held in confidence by it and, in that connection, utilizes a system to detennine when and whether to hold certain types of information in confidence.
The application of that system and the substance of that system constitute Invensys Operations Management policy and provide the rational basis required. (iii) The information is being transmitted to the Commission in confidence and, under the provisions of 10CFR Part 2.390, it is to be received in confidence by the Commission. (iv) This information is not readily available in public sources. (v) Public disclosure of this proprietary information is likely to cause substantial harm to the competitive position of Invensys Operations Management because it would enhance the ability of competitors to provide similar design and qualification ofPLC systems and associated applications using similar project methods, equipment, testing approach, contractors, or licensing approaches.
As described in section 5, this information is the result of considerable expense to Invensys and has great value in that it will assist Invensys in providing Invensys Triconex digital upgrade equipment and services to a new, expanding markets not currently served by the company.
