PLANT PIPING SYSTEMS 3/4.7.11 SEISMIC RESTRAINTS EXCLUDING SNUBBERS LIMITING CONDITION FOR OPERATION 3.7.11 Seismic restraints shall be OPERABLE on all systems required by the Technical Specifications.
Apolicability:
All MODES for seismic restraints located on systems. required OPERABLE in those MODES.
Action With one 'or more' seismic ' restraints inoperable, restore or replace' the inoperable restraint (s) to OPERABLE status within' 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> and perform an engineering evaluation to determine if the components supported bytthe subject restraint (s) remain capable of meeting the designed service, or declare the attached system inoperable and follow the appropriate ACTION STATEMENT for that system.
SURVEILLANCE REQUIREMENTS 4.7.11 Seismic restraints shall be verified OPERABLE in accordance with the requirements of Specification 4.0.5.

3.7.12 The structural aspects of seismic qualification shall be maintained for all seismically qualified piping systems required by Technical Specifications.
APPLICABILITY All MODES for seismically. qualified piping systems required OPERABLE in those L
MODES.- Prior to entering Action (c) 'or. (d) below, perform an evaluation to verify that the structurally decoupled piping system (i) does notf otherwise violate the applicable System Technical Specification,- (ii) meets code requirements for pressure, deadweight, thermal, and - other static loading conditions as applicable, and reviewed for seismic: anchor movements and seismic interaction, and (iii) does not affect the structural, qualification of j
containment penetrations
- and buried piping systems, if any.
j ACTION I
(a) All Systems:
The requirements as delineated in Specifications 3/4.7.8 l
and 3/4.7.11 apply. Additional action, if required, is as noted below.
l (b) ASME Class 1 Systems and Containment Penetrations:*
l With full seismic qualification not maintained, comply with-the action statement for that system.
(c) ANSI B31.7 or ASME Class 2 Systems:
With seismic qualification not.
j maintained on an otherwise OPERABLE and functional system in order to perform essential. maintenance activities requiring structural decoupling,-
i restore full seismic qualification within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> or-comply with i
applicable ACTION STATEMENT for that system.
(d) ANSI B31.7 or ASME Class 3 and B31.1 Systems: With seismic qualification not maintained on an otherwise OPERABLE and functional-system in order to perform essential maintenance activities requiring structural decoupling, restore full seismic qualification within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> or comply with the i
l applicable ACTION STATEMENT for that system.

, s 3/4.7.11 SEISMIC-RESTRAINTS EXCLUDING SNUBBERS All seismic restraints are required OPERABLE to ensure that the structural integrity of all safety related systems is maintained during.and following a seismic or other event-initiating dynamic loads.
When a seismic restraint is found inoperable, an engineering evaluation is performed to determine if any l
safety related component or system has been adversely affected ~by inoperability of the restraint, The surveillance and inservice inspection of component supports are required to be performed in accordance with ASME Section XI and applicable addenda-.
3/4.7.12 SE1SMIC 00At1FICAT10B Seismic qualification of all safety related plant piping systems is required to be maintained during and following a seismic or other event initiating dynamic loads.
This implies that all safety related components, equipment, and component supports maintain structural integrity at all times as required by applicable codes and standards.
1 An. engineering evaluation is performed to verify that. the structurally.
decoupled piping system:
(1) does not otherwise violate the applicable System i
Technical Specification, (ii) meets code requirements for. pressure, deadweight, thermal, and other static loading conditions as applicable, and reviewed for seismic anchor movements and seismic interaction, and (iii) does not affect the structural qualification of containment penetrations and buried piping systems, if any, i
The surveillance and inservice inspection of piping components, equipment, I
pipe supports, including snubbers is required to be performed in accordance 4
with ASME Section XI and applicable addenda to ensure that all safety related I
systems are structurally adequate and meet applicable code requirements, i
