LIMITINO CONDITION FOR OPERATION 36 PRIMARY SYSTEM BOUNDARY I.
SNUBBERS 1.
.During all modes of operation except COLD SHUTDOWN and REFUEL CONDITION, all safety-related snubbers shall be OPERABLE.
2.
If a snubber ia, determined to be inoperable, continued reactor l
operation is permissible only during the 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> following such determination unless the snubber is sooner replaced,.nade OPERABLE, i
or an engineering evaluation determined the supported system / component to be OPERABLE with the inoperable snubber.
3 If the requirements of 3.6.I.1 and 3 6.I.2 cannot be met, an orderly l
shutdown shall be initiated and the reactor shall be in the COLD SHUTDOWN or REFUEL CONDITION within 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br />.
l 4.
If a snubber is determined to be inoperable while the reactor is in the COLD SHUTDOWN or REFUEL CONDITION, the snubber shall be made OPERABLE, or replaced, prior to reactor startup.
I l
SURVEILLANCE REQUIREMENT 4.6 PRIMARY SYSTEM BOUNDARY I.
SNUBBERS Each snubber shall be demonstrated OPERABLE by performance of the following augmented inservice inspection program, 1.
Visual Inspection All snubbers shall be visually inspected in accordance with the following schedule.

M111ntone Unit 1 3/4 6-15 Amendment No, f,15 m
SURVEILLANCE REQUIREMENT (Continued)
The required inspection interval shall not be lengthened more than one step at a time.
Snubbers may be categorized in two groups, mechanical and hydraulic.
Each group may be divided into two subgroups; those accessible and those inaccessible during reactor operation.
Each group and subgroup may be inspected independently in accordance with the above schedule.
2.
Visual Inspection Acceptance Criteria
)
Visual inspections shall be conducted in the following manner:
(a) in the case where the attachments to the foundation or supporting structure are found to be insecure, the cause of the rejection shall l
be clearly established and remedied for that particular snubber and for other snubbers that may be generically susceptible (snubbers found to have insecure attachments to their foundation or supporting structure shall not be included in the table of 4.6.I.1 for determination of the next inspection interval); or (b) if there are visual indications of damage or impaired OPERABILITY, the affected snubber shall be tested in the as-found condition and, if determined OPERABLE per specifications 4.6.I.4(a) or 4.6.I.4(b), as applicable, may be excluded from the number of snubbers counted as having failed the visual inspection. Snubbers which appeared inoperable as a result of visual inspections may be determined OPERABLE for the 4
purpose of establishing the next visual inspection interval provided that the above procedure is adhered to.
However, when the fluid port is found to be uncovered, the snubber shall be determined to be inoperable and cannot be determined operable via functional testing j
for the purposes of establishing the next visual inspection interval.
3 Snubber Tests i
At least once per eighteen (18) months, duri,g shutdown, a representative sa=ple (10% of the total of each type of snubbers, mechanical and hydraulic, in use in the plant) shall be tested either in place or in a bench test. For each snubber that does not meet the test acceptance criteria of Specification 4.6.I.4(a) or 4.6.I.4(b),
as applicable, an additional 5% of that type of snubber shall be tested.
Testing shall continue until no additional inoperable snubbers are found within a sample or until all snubbers have been tested. The representative sample selected for testing shall include the various configurations, the range of size and capacity of snubbers, and the operating environment of all snubbers.
Millstone Unit 1 3/4 6-16 Amendment No.15

SURVEILLANCE REQUIREMENT (Continued)
\\
In addition to the regular sample, additional snubbers shall be tested where the previous test showed failures.
If observed failure was caused by the snubber itself (i.e., poor maintenance, degraded components, etc.) and not caused by the operating environment, the snubber unit which failed shall be tested (if it was returned to service).
If the observed failure was caused by the operating environment, the snubber installed at that location shall be tested.
If no determination was made regarding the cause of failure, both the snuboer which failed and the snubber installed at that location shall i
be tested. Test results of these snubbers may not be included for the resampling.
All replacement snubbers shall have been tested prior to installation.
a If any snubber selected for testing either fails to lock-up or fails to move (i.e., frozen in place), the cause will be evaluated and if caused by manufacturer design deficiency, all snubbers of the same 4
design subject to the same defect shall be tested regardless of I
location or difficulty of removal.
This testing requirement shall be independent of the requirements stated above for snubbers not meeting the test acceptance criteria.
For the snubber (s) found inoperable, an engineering evaluation shall be performed on the components which are supported by the snubber (s).
The purpose of this engineering evaluation shall be to determine if the components supported by the snubber (s) were adversely affected by the inoperability of the snubber (s) in order to ensure that the sups.orted component remains capable of meeting the design service.
4.
Snubber Test Acceptance Criteria The snubber tests shall verify that:
j (a) For hydraulic snubbers:
Activation (restraining action) is achieved within the specified range of velocity or acceleration in both tension and compression, and snubber bleed or release rate, where required, is within the specified range in compression or tension.
(b) For mechanical snubbers:
The force that initiates and maintains free movement of the snubber rod in either tension or compression is less than the specified maximum drag force; and activation (restraining action) is achieved within the specified range in compression and tension.
Millstone Unit 1 3/4 6-17 Amendment No.15 f
SURVEILLANCE REQUIREMENT (Continued) 5.
Snubber Service Life Program The service life of hydraulic and mechanical snubbers shall be monitored to ensure that the service life is not exceeded between surveillance inspections. The maximum expected service life for various seals and other critical parts shall be determined and established based on engineering information and shall be extended or shortened based on monitored test results and failure history.
Critical parts shall be replaced so that the maximum service lire will not be exceeded during a period when the snubber is required to be OPERAELE.
The parts replacements shall be documented and the documentation shall be retained in accordance with Specification 6.10.

Condensate Demineralizers 1.
Regeneration of and/or replacement of a condensate demineralizing resin charge shall occur before the unused capacity of the resin reaches a minimum value of 30 pounds as chloride ions.
2.
If the charge is regenerated, anion resin in the condensate demineralizing system shall have a minimum salt-splitting capacity of 0.75 mil 11 equivalents per milliliter in the wet, chloride form.
Anion resins which do not have a capacity of 0.75 mil 11 equivalents per milliliter will be replaced with new resin as will the cation resin which occupies the same bed.

If the charge is replaced, the new anion resin shall have a minimum salt-splitting capacity of 1.2 mil 11 equivalents per milliliter in the wet, chloride form.
4.

6.
Flow rate and/or integrating flow instrumentation shall be operable and recorded for each demineralizer.

a.
At least once per year or at each replacement, whichever is longer, if resin is replaced with material of the same type.
