Dear Sir or Madame:
A new reactor console has been designed and fabricated to replace the aging system presently in place at the Penn State Broazealo Reactor. Attached is a license amendment request which describes the changes to the f acility and provides a safety evaluation of the changes. Related to those changes, modifications to the Technical Specifications are requested and revised pa0es to update the Safety Analysis Report are provided. All references are available for inspection at the PSBR. The Penn State Rector Safeguards Committee has reviewed and approved this material. No significant hazards have been identified.
At an appropriate time early in the review process, we would appreciate the opportunity for our technical staff and vendor representatives to meet with your staff to respond to any questions or issues, so as to expedite the review process.
An exemption of fees for this licensing action it requested under the provisions of 10 CFR Part 170.11(a)(4).
If you have questions on this matter, please refer them directly to the principal author.of the attachments, Daniel E. Hughes, or the director, Marcus H. Voth at (814)865-6351 Sincerely, ,

License Amendment Request Penn State Breazeale Reactor License No R 2, Docket No. 50 05 Reactor Console Change April 19,1991 One of the design objectives for the replacement reactor console was to provide a state of the art design that did not require changes to the license (technical specifications). This was accomplished through separation of the reactor safety system (RSS), a hard wired analog system, and the reactor protection, control and monitoring system (PCMS), a digital computer based system. However, it was found that expanded flexibility could be permitted safely by amending certain technical specifications. Other perfunctory changes are included in this submittal for convenience.
The amendment request is divided into four separate appendices as follows:
. Appendix A: Chances to Technical Soecifications This section lists the proposed change, the reason for the changs, the safety evaluation of the change, and provides replacement pages for the Technical Specifications document.
Appendix 8: Safetv Evaluation of Reactor Console Change The existing Safety Analysis Report was reviewed to determine that the reactor console change did not constitute an unreviewed safety question as defined in 10 CFR Part 50.59. The evaluation is documented in this Appendix.
Appendix C: Instal!ation Plan This document is not part of the operating license analysis, it is provided as background information to show that the change is being made in a safe, methodical, and P udent manner. The physical change, checkout, startup testing, and training program are outlined.
Appendix D: Safety A'natvsis ReDort Revisions On M'arch 1,1985, the Safety Analysis Report was submitted in a revised and updated form along with the application for renewal of license Rf. In an attempt to keep that document current, major revisions were necessary for Section Vil, Control and Instrumentation. A replacement section is provided, which is more appropriately entitled " Reactor Safety, Protection, Control, and Monitoring System".Section IX, Safety Evaluation, also required minor changes, in addition, the appropriate editorial updates are provided with instructions for the appropriate page changes.
