However, information on interlocks that ensure safe operation is given in Section 9.1.4.3.1 of the FSAR.
Operations which could
. endanger the operator or damage the fuel are prohibited by mechanical or fail-safe electrical interlocks or by redundant electrical interlocks.
All other interlocks are intended to provide equipment protection and may be implemented either mechan-ically or by electrical interlock, not necessarily fail-safe.
In addition, Westinghouse Specification 677055 states that one end of trolley and bridge trucks shall be equipped with spring bumpers to engage solid stops at extreme limits of travel.
The other end of bridge trucks and trolley trucks shall have adjustable hydraulic shock absorbers to.stop travel.
Detailed procedures have not yet been developed, including those specifying authorization of inter-lock bypass.

"Where reliance is placed on other, site-specific considerations (e.g., re--
fueling sequencing),
provide present or proposed technical specifications and discuss administrative or physical controls provided to ensure the continued validity of such considerations."
Technical specifications dealing with refueling operations are found in 3/4.9.
Technical Specification 3/4.9.6 deals with Refueling Machine Operability.
Detailed procedures and administrative controls have not yet been developed for SHNPP, but at such time that they are, recommendations of NUREG-0612 will be followed.
Any deviations from the recommendations of the NUREG will be documented at that time.

2.2-4(c)
"Analyses performed to demonstrate compliance with Criteria I through III should conform with the guidelines of NUREG-0612, Appendix A.
Justify any exception taken to these guidelines, and provide the specific information requested in Attachment 2, 3, or 4, as appropriate, for each analysis performed."
k A design basis fuel handling accident is analyzed in Section 15.7.4 of the FSAR as the dropping of a spent fuel assembly resulting in the rupture of the cladding of all the fuel rods in the assembly.
For a Postulated Fuel Handling Accident Inside Containment (drop of a fuel assembly into the refueling cavity by the manipulator crane),
the resultant doses have been'calculated, assuming no containment isolation, and have been found to be below the guidelines of 10CFR100.
The criteria of NUREG-0612, Section 5.1.3 are met for load handling operations in the Containment Building (Alternative (2)
Rapid Containment Isolation).
Section 6.2.4.1(d) of the FSAR states that upon detection of-high containment atmosphere radioactivity, isolation valves in the Containment'tmosphere Purge
=Exhaust System, discussed in Section 9.4.7, are shut to control release of radioactivity to the environment.
The Containment Purge Isolation Actuation System is discussed in Section 7.3.
Airborne radioactivity monitoring is discussed in Section 12.3.4.

The presentation in a matrix format of all heavy loads and potential impact areas where damage might occur to safety-related equipment.
Heavy loads identification should include designation and weight or cross-reference to information provided in 2.1-3(c).
Impact areas should be identified by construction zones and elevations or by some other method such that the impact area can be located on the plant general arrangement drawings."
See attached Load/Impact Area Matrix Note:
-It was previously reported (Section 2.1 response) that the new fuel container was to be transported by the FHB Cask Crane.
However, this

~Re uest:
2.4-2(b)
"For each interaction identified, indicate which of the load and impact area combinations can be eliminated because of separation and redundancy of safety-related equipment, mechanical stops and/or electrical interlocks, or other site-specific considerations.
Elimination on the basis of the afore-'entioned considerations should be supplemented by the following specific information:
(1)
For load-target combinations eliminated because of separation and redundancy of safety-related equipment, discuss the basis for determining that load drops will not affect continued system operation (i.e., the ability of the system to perform its safety-related function).
(2)
Where mechanical stops or -electrical interlocks are to be provided, present details showing the areas where crane travel will be prohibited.
Additionally, provide a discussion concerning the procedures that are to be used for authorizing the bypassing of interlocks or removable stops, for verifying that interlocks are functional prior to crane use, and for verifying that inter-locks are restored to operability after operations which require bypassing have been completed.
(3)
Where load/target combinations are eliminated on the basis of other, site-specific considerations (e.g.,
maintenance sequencing) provide present and/or proposed technical specifications and
discuss administrative procedures or physical constraints invoked to ensure the continued validity of such considerations.
(1)
Diesel Generator Bridge Crane Redundant diesel generators exist for each unit.
Each generator is served by a separate crane.
As only one diesel generator is required for safe
- shutdown, a load drop in this area would not affect system operation.
Miscellaneous Hoists and Trolleys1.
Items 2, 3, and 14 will only be used when the component each one serves is taken out of service.
Each component has redundant counterparts, each served by a separate hoist and trolley.
Therefore, a load drop in any'of these areas would not affect safe shutdown.
Item 6:
The seal water injection filter and feed filter have redundant components served by a separate hoist and trolley.
The reactor coolant filter, seal water return filter, and boric acid filter can be'bypassed in the event of failure.
- Thus, no threat is posed to safe shutdown in the event of a load drop.
Circular Bridge Crane The primary shield cooling fan, reactor supports cooling fan, electric hydrogen recombiner, and containment fan coolers have redundant components.
Failure of one component would not affect system operation.
Jib Crane The excess letdown heat exchanger and containment fan coolers have redundant components.
Failure of one component would not affect system operation.
(2)
FHB Cask Crane The crane interlocks and mechanical stops have been discussed in response to 2.2-4(b) of this report.
As specified in Section 9.1.4.2.2.7 of the FSAR, there is no safety-related equipment within the possible area of the main hook (and therefore, fuel cask) travel, either on the operating floor or on floors beneath.
(3)
Circular Bridge Crane Jib Crane These two cranes will be used for refueling and maintenance purposes; therefoxe, no threat will be posed to safe shutdown of the reactor.
Procedures have not yet been developed for SHNPP, but at such time that they are, recommendations of NUREG-0612 will be followed.
Any deviations from the recommendations of the NUREG will be documented at such time.

Manipulator Crane See response to 2.3-4 for analysis of load drop.
FHB Bridge Crane See response to 2.2-4 for analysis of load drop.
Turbine Gantry Crane Credibility of a load drop from the operating floor in such a manner to interrupt flow in the underground service water lines is under evaluation at this time.
Xn addition, load handling systems operating in the Containment Building are in compliance with NUREG-0612, Section 5.1.3 due to rapid containment isolation.
See response to 2.3-4 for further details.

f, SCOPE This specification defines the seismic considerations 8vurffing and after Safe Shutdown Earthquake (SSE) and Operating Basis Earthquaiae (OBE),. as defined
.in the equipment specification in which this specificaMon is referenced or
- attached, for any equipment and its supports for which Category I seismic considerations are designated as applicable.
2o SEISMIC RE UIRRiENTS fi Equipment and equipment supports shall be designed and evaluated by analytical and/or experimental. procedures described hereinafter, 'far earthquake
- effects, to insure that they. wiLL remain functional during and Gallowing the postulated seismic event
. Equipment functioning in the required mode of operation during and after the seismic disturbance will be considered te have suffered no loss of function.
.01 Equipment and equipment supports subject to SeisMc Category I consider-ations shall be designed to safely withstand simultanecrusly acting horizontal
'nd vertical earthquake effects (vertical earthquake effects acting in either upward or downward direction to give the most severe cazb~ation) in accor-dance with values given in the corresponding floor response spectra contained in the. base specification.
.02 In design of supports, no credit shall be taken Gor friction in equip-
'ant displacement.
This applie's to all internal and e~ternal components which shall be designed and supported to assure that no intezfezence or undue de-flections will occur.
SEISMIC UALIFICATION
'fi fi For the equipment and its supports, Seller must demonstrate the ability of the supported equipment to remain fully functional during and after the seismic disturbances.
The preferred acceptable aathod of demonstrating this ability shall be'ccomplished by testing of the sr~ported equipment
'under simulated earth'quake conditions applicable. to the g.ven project-How" ever if such testing is not within the scope of pract" cal limitations, one f
or more of the following methods may be used; with Purchaser-s concurrence
'ith Seller's justif~cation for the choice of proposed methods or procedures.
a - Complete mathematical analysis for determinaaion of supported equip-ment perfoxmance b - Documentation of successful test or analyst of prototype equipment subjected to similar or higher earthquake eMects

Maximum nozzle, loads together with other functional parameters of the equipment shall be, taken into consideration by Seller for each operating condition of the equipment (normal, upset, emergency and faulted condi-
'ions) when using one of the aforementioned procedures.
The documentation provided for seismic qualification of suppozted equipment must clearly )ustify the'hoice of demonstration method utilized.
The seismic effects are represented by means of floor response spectra which are developed for the two ma)or horizontal and one vertical direction at different levels throughout the height of.the buildings.
These spectra represent the "maximum accelerations to which the supported equipment may be sub)'ect, depending on the natuxal periods of vibration of the equipment, and as determined fo'r the damping factor corresponding to the equipment.
The response spectra peaks are broadened by Purchaser to account for frequency, shift due to uncertainties in the 'analysis.and material properties.
One set of such spectra is developed for the Operating Basis Earthquake (OBE),
and 'one'et for the Safe Shutdown Eax'thquake (SSE).
The following briefly describes the procedures to be followed in using the methods indicated above.
The test program is required to confirm the functional operability of elec-trical and..mechanical equipment and instrumentation during and after specified earthquake events.
a - The characteristics of the required input, motion are specified by response spectra specified above.
Seller may use one of the foLlowing input motion representation character" sties in performing the, tests:
i - Response spectrum ii.- Power spectral density function
~
~
iii-Time histozy Such characteristics, represented by Purchaser'.s spectra
- curves, are derived from the structures or systems seismic analysis test motion and shall be representative of the input motion at the equip-ment mounting locations, ie:
the motion shall be such that the resulting response spectra shall envelope the design response spectra provided.

Operability shall be verified during and after the testing.
c - The actual input motion shall be characterized n the'pame manner as the required input motion.
The test input n:.ation shall be conservative and can be achieved by varying the input parameters
. such as amplitude and the range of test frequeacies.
d - As seismic excitations generally have a broad frequency content, raadom vibration input motion shall be used.
Eowever, single frequency input, such as sine beats or other w"-veforms, may be applicable provided one of the following conditions is met:
The characteristics of the required input amtion indicate that
'he motion is dominated by one frequency (ie:
by structural filterLng effects).
ii -" The anticipated response of the equipment M adequately repre-sented by one mode.
Sii - The input has sufficient intensity and duration to excite all modes to the required magzd.tude, such that Ne testing response spectra wQ.1 envelope the corresponding response spectra of the individual modes.
e - The input motion shall be applied to one vertical and one principal
{or two orthogonal) horizontal axes simu2.taneously unless it can be
', demonstrated that the equipment response along Qxe vertical direction is not sensitive to the vibratory motion along the horizontal direc-tion, and vice versa.
f - In the case of a single frequency input, the Mme phasing of the inputs in the vertical'and horizontal directions must be such that a purely rectilinear resultant input is avoided.
If the test in-
. puts in the two axes are identical and in phase, then the test shall be repeated with the inputs 180 degrees cut of phase.
There-fore, for multiaxis testing, independent rando~ ~~puts are recom-mended.
I g - Unless it can be shown that the equipment has symmetry about the vertical axis, the equipment shall be rotated 90 degrees and retested.

~ 02 Mathematical Anal sis Method This method may be used for equipment and its supports which does not lend it-
self to testing as'indicated in Paragraph 3.01 and which can be properly modeled snd mathematically analyzed to obtain its response during the seismic event.
This method does not, however, provide sufficient assurance as to maintaining the proper "inside" operation of certain equipment (such as switches, level indicators, etc) and for these cases actual performance testing procedure must be applied.
The mathematical analysis method shall consist of but not be limited to the following:
a - Model the equipment and supports with sufficient. degrees of freedom to ensure adequate representation in two ma)or horizontal and the vertical directions.
b
-. Determine the natural frequencies and mode shapes of the equipment and supp or ts o If the analysis of the model yields "rigid" characteristics, ie:
natural period of vibration of predominant mde of supported equipment'. equal to or less than 0.03 seconds, Seller may apply the seismic acceleration coefficients, obtained from applicable response spectra curves, statically, and perform the static analysis on the equipment and supports.
The vertical and two horizontal
'seismic effects are to be applied simultaneously to the weights of components at their gravitational centers for the seismic load cal-culation and design.
For supported equipaent with "flexible" characteristics, ie:
having the natural period of vibration more than 0.03 seconds, Seller shall obtain the equipment responses by use of Response Spectra Modal Analysis Techniques.
The input response acceleration values will be obtained from the applicable response spectra curves.
The Time History Analysis method may also be used if the proper input time history data is available.
. The square root of the sum of the squares method'should normally be used to combine the modal responses when the Response Spectrum Nodal Analysis method is employed.
In those
- cases, however, where modal frequencies are closely spaced, the responses of the closely sp'aced modes should be combined by the sum oi the absolute values
'mthod and, in turn, combined with the responses of the remaining significant modes by the square root of the sam of the squares.

- codes, and app1.icahle regulatory guides of the Nuclear Regulatory Commission.
g - If the codes and regulatox'y guides are not spec" fXc, the stress fzom earthquake loads shall, be'dded directly tc the stresses from other applicable loadings.
The allowable =-.tress shall not be increased due to the addition of the OBE ear-hquake load.
'he allowable stxess may be increased due to the,.addition of the SSE earthquake load to a limiting value of 90 percent of yield stzess of materials, provided no undue deflection takes place.
h - The analysis shall include evaluation of the effects of the cal-culated stresses and deflection under eazthquaka load effects on mechanical strength, alignment and electrical c>wracteristics.
03 Combined Anal sis and Testin Impedance testing is particularly apt when the equipment to be qualified is too
'arge to be mounted on a shake table.
Portable vibration. generators can be used to excite the modes of the equipment-This data can then be used to establish mathematical models in qualification by analysis, or in determining
- 'transfer functions for component testing.
An alternativa is to simulate the effects of 'a SSE by single or multiple mode excitation as applicable.
Equipment may be qualified using analysis to extrapolate -est results.
This is particularly apt when there are many different combin~ti.ons of an equip-ment which is basically of the same type.
Changes may be due to different devices ox sizes.
Here it is impractical to test every -rariation.
Tests must be designed to gather sufficient data to enable valid mat:hematical models to be established.
Other combined methods include shipping vibration and shack testing.
These methods ari intended primarily to produce valuable back-up information.

two ma)or orthogonal horizontal directions and one vertical direction as the actual equipment.
The model shaI.1 consist of a system of mass points.with the span and direction between each mass point defined.
For each span, geometric and material prop<<
ezties shall be given sufficiently to define the conventional 6 x 6 matx'ix establishing the three translational and rotational motions uader external loading and shall iaclude:

The purpose of these.zequirements is the definition of xmdels for nonrigid equipment which are compatible with Ebasco analysis of pz.ping systems.
Mith-in this context, Seller shall have complete freedom as tu the number'f mass points and other variables, the requirement being his cez.tification that the
