R-23 DOCKET NO. 50-59 The U.S. Nuclear Regulatory Commission (NRC) has reviewed your responses to our requests for additional information (RAIs) and has identified the following RAI responses that need additional clarification.
RAI No. Original RAI Description RAI Response Date Additional Clarification Needed 06 Describe the design criteria for the console upgrade.
12/22/2011 Please describe the hardware components and software associated with "AGN computer" discussed in Chapter 7 of the Safety Analysis Report (SAR). Include a discussion of what verification and validation was used for the design and installation. Identify which reactor scram signals are generated by the" AGN computer" and which ones are hardwired directly to the scram circuit. Describe the design elements addressing the potential for a single failure disabling multiple scram inputs.
07 Limiting Condition of Operation for the skirt radiation monitor scram. 12/02/2011 Please explain why the Limiting Conditions for Operation (LCO) for a scram was proposed for section 3.4, "Radiation Monitoring, Control, and Shielding" instead of section 3.2 "Control and Safety Systems" which contains a listing of all of the other scram inputs 08 Channel #2 Period Scram design impact from the AGN
computer 04/12/2012 Please explain how the "computer" calculates the period and how frequently this is compared to the trip set point. Explain the safety impact of using a computer for this function compared to the previously installed rate meter. RAI No. Original RAI Description RAI Response Date Additional Clarification Needed 09 Channel #3 Linear Power Scram design impact from the console
upgrade 04/12/2012 Describe how the "AGN computer" takes the signal from the picoammeter and generates a scram signal based on the output of the Channel #3 detector. How often is the signal compared to the set point and what processors are involved? What is the cumulative effect of the delay associated with each step between an increase (or decrease for low power trip) in the detector output and initiation of a scram signal including processor delays associated with the other processor demands on the "AGN computer"? Explain what digital filtering is used and how this affects the overall response time.
11 Reactor Control System does not show how the Interlock Relay function was incorporated into the upgrade.
12/22/2011 Your statement that "There was no Technical Specification (TS) requirement for this interlock feature" is not consistent with the current wording TS 3.2.e, 3.2.f and 3.2.g. Please explain how you are complying with the requirement to have "shield water level interlock," and "shield water temperature interlock" that will "prevent a reactor start up and scram the reactor" 13 Incorporation of the "watch-dog" scram into the appropriate LCO and Chapter 13 update 04/12/2012 The proposed wording for LCO 3.2.k contains the word "installed." It is not clear what is meant by the word "installed." Please provide a definition for the word "installed," to be included in section 1 or consider the use of a defined word such as "operable" or "operating" in the proposed LCO.
Please provide a safety analysis of the design change that discusses the "AGN computer," its potential failure modes, and what features are relied
upon to ensure operability (ability to perform its intended safety function).
14 Radiation protection program and as low as reasonably
achievable ( ALARA) considerations 08/25/2011 Some of the survey locations indicate a dose rate greater than 10 milli-Roentgen Equivalent Man/hour (mrem/hr). What actions are being implemented in these areas to ensure ALARA principles are considered?
The RAI response indicates three phantom monitors are present at the facility. What are these phantom monitors and how are they used? The RAI response also indicated, "facility personnel "are supplied with dosimetry.
Who is considered to be "facility personnel" and what type of dosimetry is used? RAI No. Original RAI Description RAI Response Date Additional Clarification Needed 15 Ar-41 production consideration 08/25/2011 The percentages of the 10 CFR Part 20 Appendix B Derived Air Concentration (DAC) and effluent release limits are provided in the RAI responses which are based on a dose rate. Based on the maximum allowed operations, what annual dose does this represent to the occupational workers and to members of the public?
17 Personnel monitoring during experiment handling 08/25/2011 Are students allowed in the reactor room when the reactor is operating? What type of dosimetry is required for the students? Explain how this is controlled (procedure, etc.).
20 Evaluation of MHA related to occupational dose limits 12/02/2011 Amendment 10 only considered one of the severe accidents (slow controlled excursion) 1% reactivity increase without the fuse melting. The original MHA also consider a 2% step reactivity increase (runaway) with fuse melt. Please discuss why the 2% step reactivity increase MHA scenario was not considered in your analysis related to dose limits.
21 Add TS definitions per ANSI/ANS-15.1-2007 guidance for: reactor secured, reactor
shutdown, and shutdown margin. 12/02/2011 The proposed TS Section 1 definition for Reactor Shutdown (1.19) includes a reference condition of $1.00. Please provide the relationship between
$1.00 and the %k/k or propose wording for the definition of shutdown that is expressed in %k/k consistent with other TSs.
24 The proposed TS 3.2 and Table 3.1 do not include Interlock Relay Scrams 12/02/2011 The previous console included interlocks for the Rod Drive Cable and Relay Chassis. Activation of these relays resulted in an automatic reactor scram. Please explain why these automatic scrams are no longer required including a discussion of the safety impact of replacing these automatic scram functions with operator action.
RAI No. Original RAI Description RAI Response Date Additional Clarification Needed 25 TS 3.2.g states that a seismic displacement interlock switch shall be installed. This requires a set point. 12/02/2011 Per TS 4.2.h - The shield tank water level interlock, shield water temperature interlock and seismic displacement safety channel shall be tested by perturbing the sensing element to the appropriate set point. These tests shall be performed annually, but at intervals not to exceed 16 months.
The reply indicates the switch cannot be calibrated because of its design.
Please explain how Texas A&M is in compliance with TS 4.2.h if the set point cannot be verified. Additionally, please justify the use of this interlock.
29 Maximum Hypothetical Accident assumptions include no escape of fission products from the core tank. Propose changes to 3.4.f for core tank seal integrity 12/02/2011 Please state how the fission barrier boundary integrity (core tank seal) is ensured via an appropriate TS LCO.
