1.1.1 ITT Grinnell mechanical suppressors are acceleration sensitive devices used to prevent seismic shock forces frem causing damaging motions in piping and relatad systems. The suppressors, purely mechanical in design, control such motion by becoming lead carrying members between the piping or related i
systems and building structure when a force sufficient
~
to cause abnormal motion is initiated. This poten-I E
tially damaging motion is arrested and abscrbed to acceptable limits. During normal thermal expansion 4
i or contraction of the piping or related systems, the suppressors telescope freely in either direction O
through their fo u operating st=oxe.
1.1.2 The restricting function of the suppressor is primarily i
l achieved by converting linear telescopic motion into rotary motion, see Dwg. No. AH-1655.
When a seismic disturbance occurs that exceeds the threshold "g" level l
I 10.02 *g") the telescopic action of the telsceping
- tube and the support cylinder rotate (through the re-j circulating bearing) the screw shaft which in turn rotates the inertia mass. The inertial resistance of I
j the inertia mass causes the capstan spring to tighten round the support cylinder. When this occurs, a re-f straining force is applied against rotation of the i
screw shaft and, in turn, against linear telescoping of the support cylinder and the telesecping tube.

2.2 Uncrating and Inspection i
2.2.1 Upon receipt, each carton must be visually inspected for external damage. Any evidence of external damage which has penetrated the carton should be documentated on the shipping p' apers.
J[
Note: Any carton with visible external damage should be opened immediately to inspect for internal damage. The carrier must be notified immediately j
of any damage found.
b (h 2.2.2 Uncrating 1.
The steel strapping should be cut with metal cutting shears or other suitable means.
8 2.
The staples should be removed from the top flaps with suitable staple pullers.
- Caution: Do not open the carton by cutting the carton.
3.
The carton is filled with energy absorbing packing material. Sufficient packing must be removed manually to allow unobstructed access to the shock suppressor.
4.
Small shock suppresects (up to 3 kip) may be lifted from the carton manually. Larger shock suppressor:
(10 kip and up) should be removed using appropriate slings and a hoisting mechanism.
I
- caution: Shock suppressors are to be lifted by the body only. Never attempt to lift by the i
'end cap (Ref. Cwg. AH-1655). The shock
(
suppressor is a precision compenent and r
must never be drepped, shaken, or 4
iolted.

In order to reserve the space required for the proper installation of the snubber, installation of a fragile mockup or surrogate, consisting of s=all bar stock at.d sheet metal is recommended. The fragile mockup should represent the space envelope to be occupied by the snubber.

- The purpose of this procedure is to specify._ttie requi_re-ments for design verification for Comanche Peak Project
~Engineerini({_PP(J~dsignedJroiects_to ensure that a new d or revised design adequately satisfies its intended func. tion. 2.2 DEFINITIONS ( 2.2.1 Desian Verification - The process of reviewing, confinning .qr _ substantiating the desigif by o~ne or more m,eth'ods to provide assuranc6 that the design meets the specified in-puts. Acceptable verification methods include but are not limTted t~o1Disigh R'ifew,"Alternat'e CalciTations, and e ~ Qualification TestTng. 2.2.3 Alternate Calculations Design verification method that employs comparison with alternate calculation or analysis. The alternate method may be a more simplified or less rigorous approach. 2.2.4 Qualification Testino Verification achieved by suitable testing of a prototype or initial production unit. 2.3 RESPONSIBILITIES l The Original Designer shall authorize their personnel ' I at the site or in the CPSES Project Engineering Group to perfona design reviews / verifications. m0?

I ( TEXAS UTILITIES SERVICES INC. REVISION PAGE CP-EP-4.5 1 2-18-80 2 of 3 3.1 GENER'L A Design verification shall be done in accordance with sub-ordinate instructions that outline the requirements and/ or the method (s) to be used. Design verification shall be. performed by other than the one who performed the original calculation. When verifying changes to a previously verified design, verification shall include an evaluation of the effects of these changes on the overall design. Design verifications will be verified by the original designer when applicable. Deficiencies identified during design verification shall be identified, documented and resolved as per the require-ments of Reference 1-A. Acceptable methods for design verification include Alter-nate Calculations and Qualification Testing. 3.2 ALTERNATE CALCULATIONS When using alternate calculations for design verifciation, a. Appropriateness of assumptions, input data and the code requirements used during the original calculations shall be reviewed; (e.g. hand calculations vs. computer) b. Even if the simplified alternate calculations do not exactly check the original calculations, they must be consistent with the original calculations. 3.3 QUALIFICATION TESTING When verifying design by qualification testing: a. Qualification testing shall be designed to demonstrate adequacy even under the most adverse conditions. b. If qualification testing is designed to verify a spe-cific design feature then the other features shall be verified by other means. c. It shall be perfonned in accordance with procedures which make provisions for insuring that the pre- { - requisites have been met, adequate instrumentation is available and that necessary monitoring is performed.
