GE Response on Tech Spec Items in AllWR Draft FSER TS Item Description
Response
3.9.6.2.4 1 Surveillances for pressure isolation see AllWR Tech Specs, SR 3.4.4.1 valves 4.4-1 RIP operating limits see AllWR Tech Specs,1 C0 3.4.1 - NOTli: Gli has revised the approach to partial pump operation to require 9 or 10 RIPS in operation. With less then 9 RIPS in operation, continued plant operation will be appropriately limited.
5.2.3-1 Chemical control for primary coolant Control of reactor coolant chemistry limits has bece removed from the improved tech specs (NUREG-1433/1434) and tims will not be included in the AllWR tech specs.
Such control is to be accomplished in the future via appropriate administrative controls outside of tech specs.
5.2.5-1 Limiting conditions for leakage see AllWR Tech Specs,1.C0 3.4.3 for actual RCS leakage limits and I.CO 3.4.5 for operability of associated instrumentation.
5.4.6-1 ECCS functional testing see AllWR Tech Specs, SRs 3.5.1.5, 3.5.1.6 & 3.5.1.7.
5.4.7-1 RilR see AllWR Tech Specs, see I.CO 3.5.1 and SRs 3.5.1.1,3.5.1.2, 3.5.1.4 & 3.5.1.7 6.2.1.5.1 - 1 Inspection and testing of vacuum see AllWR Tech Specs SRs 3.6.1.6.2 & 3.6.1.6.3 Iweakers 6.2.1.6-1 Suppression pool temperature limits see AllWR Tech Specs,: CO 3.6.2.1 6.2.4.1-1 Allowable leak rates for isolation valves see AllWR Tech Specs. SRs 3.6.1.3.7, 3.6.1.3.12 & 3.6.1.3.13 6.2.5-1 24-hour window at beginning/end of see AllWR Tech Specs, SR 3.6.1.3.2 and I.CO 3.6.3.2. - NOTE: The link hetwecn fuel cycle the large purge valves and the 24-hour window is only implied in that the valves are required to remain chised during MODES 1,2 & 3 cxcept when being used for inerting, de-inerting, etc. 'lhe 24-hour window is associated with the requirement for drywell oxygen concentration which is indicative of an inerted condition in the drywell.
see AllWR Tech Specs, LCO 3.3.5.1 & Table 3.3.5.1-1. ADS bypass timer testing is 6.3.3-1 ADS bypass timer periodic testing included in SRs 3.3.5.1.2,3.3.5.1.3, and 3.3.5.1.4 because the timer is implemented in the SSI.C, not a separate mechanical timer.
i 6.3.4.2 1 ECCS subsystems periodic testings see AllWR Tech Specs, SRs 3.5.1.4, 3.5.1.5, 3.5.1.6 & 3.5.1.7.

6.3.5-1 lixposure-deperaient API.lRiR see AllWR Tech Specs, I.CO 3.2.1 - NOTli: The actual APLilGR limit is a fuel cycle specine value and un&r the improved tech specs will be included in the Core Operatmg 1.imits Report to be updated for cach cycle
'the OPRM scram setpoint is a new RPS input diat will be included in LCO 3.3.1.1.
specs Rcrer to Table 3.3.1.1-1 in LCO 3.3.1.1.
7.5.1-1 Accuracy requirements Plant specine AllWR tech specs will specify " Allowable Values" that are calculated lused on an approved setpoint methodology which incitales consideration of required instrument accuracies. Since such determinations require as-built anal /or as-procured information, they will be the responsibility of the COL holder once such information is available.
I1.5.1-1 RMS alarms when tallevels exceed Control of radwaste discharge limits has been removed from the improved tech specs operating limits (NURiiG-1433/1434) and thus will not be incitated in the AllWR tech specs. Such control is to be accomplished in the future via appropriate administrative etmtrols outside of tech specs.
14.2.10.1-1 RPV levelkhemistry check before fuel RPV water level and chemistry checks are not specine tech spec items but will be kul included as specinc prerequisites in the fuel hxxling procedure (sce 14.2.12.2.3).
Operability of required neutron instrumentation (including proper calibration) will be assured via LCO 3.3.1.3 which is required to be met prior to commenecment of fuel hiading (i e., prior to entry into MODli 5).
14.2.12.4 1 RG 1.68, Position 2.c demonstration As stated, Section 14.2.12.2.3 speciGcally requires such demonstration prior to prior to fuelload commencement of fuct loading. Furthennore, such demonstrations will be assured as part of the tech spec program (LCOs 3.3.1.1 & 3.3.1.2) which must be instituted prior to entry into MODli 5 0.e., prior to commencement of fuel hiading).
15.1-1 Availability, set points, surveillances of Operability of turbine bypass valves is assured by I.CO 3.7.5. Operability of non-safety equipment instrumentation for Level 8 trip and Rirl' will be assured by LCO 3.3.2.2 and LCO 3.3.4.1, respectively.
15.4.4.1 1 Suppression pool depth arxl DW leak-see AllWR Tech Specs, SR 3.6.2.2.1 & 3.6.1.1.1 for verincation of suppression pool tightness level (depth) azul drywell Icak tightness, respectively.
15.4.4.3-1 Post-LOCA leakage Leakage imm primary coolant sources outside containment is controlled administratively, through the program required by TS 5.7.2.4, required to be provided by the COL applicant as Section 5 of the AllWR Tech Spec is to be provided by the I
COL applicant.

15.5.1.2.1-1 Operability of drain valves
'Ihis valve is a pneumatically operated, normally closed, fail open valve. The valve is classified as ASMii Category ll, and is subject to the in-service testing (IST) program (15.4.4.2.1-1) requirements of Section XI. As such, the valve is to be stroke tested at 3 month intervals (see SSAR Table 3.9-8 for Valve # It21-IT)l7). This testing is sufficient to assure the valve's operability and thus further operability requircinents via tech specs are tot needed.
20.3-1 Outage times for ECCS components 1his TS Item appears to be commentary regarding allowabic outage times for ECCS mal associated support systerns and does not address any specific tech spec requirements.
Iturthermore, the Standan! Tech Specs (NUREG-1433/1434) have no cumulative outage time limitations for ECCS. Such requirements are to be addressed outside of tech specs, for example, the Reliability Assurance 1% gram.
