small in comparison to the mass of the ship and the analysis is based on maximum possible elastic collision', the results apply to smaller missiles as well.
2.9.2 REQUIREMENTS IMPOSED BY P0TENTIAL AIRCRAFT CRASH ON THE PLANT Requirments The owner must provide a site where the probability of a crash producing unacceptable plant damage is of the order of 10 7 Der year or less. l8 Justi fica tion The oasis for the probability value of the order of 10~70er year is discussed in the l8 introduction to section 2.9. Example calculations for representative sites are contained in Appendix 28.
Methodoloay Two methodologies have been utilized for determining aircraft accident probabil i ty. One is for crashes associated with overflights (along flight corridors)
Amendment 8 2.9-7 May 15, 1974
nd one is for those crashes attributed to take-offs and landings. The latter were considered only for tnose sites in proximity to airfields.
These two methodologies are described in detail in Appendix 28. Briefly, they are based either on records of crash rates per year, per mile flown (for the overflight case), or crash rates per aircraft movement for the near-airfield case. Both methodologies contain a distribution factor for the spatial distribution (away from a corridor, or away from an airfield).
2.9.3 REQUIREMEflTS IMPOSED BY P0TEllTIAL EXPLOSION NEAR THE PLANT WITH RESULTING MISSILES Requirement Regulatory Guide 1.91, Revision 1 requires that nuclear facilities be able to withstand the possible effects of explosions occuring on nearby transporta-tion routes. The Guide specifies the following three options for complying with this requirement:
0
- 1. Demonstrate that the peak positive incident overpressure resulting from cny postulated transportation accident in the vicinity of the plant will not exceed 1 psi, or
- 2. Demonstrate that the probability of the above overpressure limit being exceeded is acceptably low (less than 10-7 per year; 10-6 if based on demonstrably conservative assumptions), or Amendment 26 January 3, 1979 2.9-8
- 3. Demonstrate that all safety relat1d structures can withstand the explosion loads, if these loads exceed 1 psi incident overpressure. 26 The site envelope (Table 2.1-1) requires that each plant owner comply with either option 1 or 2 (above) by demonstrating that at each Fi4P site the probability of a shipment of munitions or petroleum products becoming involved in an accident near the site, with a subsequent detonation which produces a reflected over-pressure of 2 psi (I) or greater at the plant's Category I structures is of l 26 the order of 10~7 per year or less. For fuel supply barges, either the size of the tank compartments must be limited to 325 barrels or the owner must utilize off-loading procedures which preclude the possibility of an explosion (2). l 26 Justification The basis for the probabilities value of the order of 10-7 per year is dis-cussed in the introduction to Section 2.9. A review of waterborne commerce of explosives shows munitions are the only comodity shipped as explosives in (I) Instead of the 1 psi peak positive incident overpressure criterion stated in the Regulatory Guide, a 2 psi maximum reflected overpressure criterion is utilized for the Floating Nuclear Plant. This criterion in no way alters the effect of the regulatory guide criterion, since both values result in virtually identical " exclusion distances". This can be seen by comparing the values of K (scaled ground distance) obtained for 2 psi 26 reflected overpressure from figure 4.12 of Reference 4, with the values of K suggested by the Regulatory Guide.
(2) Appendix 2A contains analyses of two accidents in.olving detonation of explosive cargo in the plant vicinity: (1) A fuel supply barge with 325 barrel tank compartment, at 150 feet from the plant and (2) A cargo ship carrying munitions or aertroleum products, at various distances from the plant site.

The relative numbers of MSC and Navy vessels loaded at Earle for 1968 through May 1973 are given in Table 2A-12. It is believed that all of the 3 MSC vessels headed south while most of the Navy vessels headed north or east (3) ,
Two further types of shipment are made from Earle. A few foreign vessels load partial loads of ammunition under military assistance programs for U. S. allies. These are not included in the number of loadings tabulated.
Also V. S. warships replenish their amunition magazines at Earle. Warships are not considered a threat as munitions carriers because the quantities of munitions are much smaller than those on the cargo vessels and the maga-zines are well protected against impact damage or fire.
Munitions shipments in transit are not regarded as hazardous cargo by the U. S. Coast Guard and the ships are considered as normal cargo vessels.
Safe distances are, however, specified for loading and unloading or while the ships are at anchor in port. The stowage of the cargo is subject to Department of Defense regulations and these have recentl" been made more stringent following the loss of the " Badger State" in December 1969. This accident is discussed below.
2A.4.3.2 Recent Munitions Ship Accidents There have been only two accidents to munitions ships in the last four years. Both were vessels on charter to the MSC. 3 Amendment 3 2.A-51 January 28, 1973
On ftarch 5,1969, the AMERICAN PRODUCER carrying miscellaneous military munitions collided with a reinforced concrete pier in San Francisco harbor.
The vessel was moving at 11 knots and turned to avoid a vessel that failed to give right of way. The horizontal deck of the pier cut a slot in the vessel from the bow to 60 feet back. The vessel was declared a total loss by the insurers. There was no explosion.
On December 26, 1969, the BADGER STATE, a C2 cargo vessel, carrying bombs, sank in the Pacific in heavy weather. The ship foundered after the bombs broke out of their stowage racks and began smashing around in the holds.
The ship was finally abandoned after a low order (i.e., slow burning) detonation blew a hole through the side of one of the holds. No one was killed as a direct result of this explosion. There was no mass detonation of the cargo. As noted above, stowage requirements have been made stricter as a result of this accident.
In the last three years, 829 shipments were made from the four major munitions terminals (Table 2A-12).
2A.4.4 Detonation Analysis 2A.4.4.1 Maximum Permissible Detonation Without Serious Plant Damage The Applicant concurs with the judgement of the NRC Staff (as expressed in Regulatory Guide 1.91) that no significant plant damage would result from an explosion producing an incident overpressure of 1 psi. As noted in Section 26 2.9.3, an incident overpressure of 1 psi is equivalent to a reflected over-pressure of 2 psi.
Amendment 26 January 3, 1979 2A-52
to the off-loading dock is the spent fuel pit missile barrier which would be about 142 feet from the barge. This structure would not be damaged 26 significantly by a pres. -a pulse of 2.0 psi (reflected). The analysis indicates that tank compartments with volumes up to 325 barrels will not produce excessive reflected overpressure at the fuel pit missile barrier.
Overpressure values are plotted versus distance and time for both analysis cases (10,000 barrel barge and 325 barrel compartments) in Figure 2A-42 and 2A-43, respectively. The TNT equivalents from the barge-tank explosion are 895 lbs and 30 lbs for the two cases. Methods that might be used for ensuring that an explosion would either not occur during off-loading or would not produce excessive overpressures on plant structures are the responsibility of the site owner. They could include inerting of the fuel barge tanks dur-ing off-loading, separation between the plant and fuel supply barge during fuel off-loading, or other appropriate measures.
The particular approach used to prevent an explosion of unacceptable magni-tude near the plant during off-load'ng of a fuel resupply barge is the re-sponsibility of the site applicant. The applicant must either limit the volume of the individual tanks on the resupply barge to 325 barrels or pro-vide off-loading procedures which preclude the possibility of an explosion during off-loading.
Amendment 26 January 3,1979 2A-137
2A.8.3.2 Missile Generation Analysis Fuel supply barge debris or fragments resulting from the fuel-air explosion are missiles and have potential for damaging the plant if the explosion were to occur near the plant. The missiles resulting from a fuel-air explosion of an integral tank will consist of steel plates, deck fittings, man-hole covers, bitts, chocks, anchors and piping. This debris will be considered to fall into three classifications:
- a. Small parts weighing less than 20 pounds consisting of bolts, rivets, rail fittings, small plumbing fittings and small plate fragments.
- b. Medium sized parts weighing between 20 and 200 pounds consisting of manhole covers, piping and smaller deck fittings, and plate fragments.
- c. Large parts weighing more than 200 pounds and consisting of capstans, 23 bitts, chocks and large sections of steel plate structure.
The nature of the fuel-air explosion is such that failure of the supply barge structure will be similar to the failure of a pressure ven?1 rather than the shock fragmentation of materials which is experienced with the detonation Amendment 23 September 10, 1976 2A-137a
3.5.2 Postulated Sources and Protection Criteria for Missiles External to the Containment Five sources of missiles have been postulated external to the containment.
- 1. Tornado and waterspout borne missiles
- 2. Turbine-generator missiles
- 3. Missiles resulting from the crash of a helicopter
- 4. Missiles resulting from failure of compressed gas cylinders
- 5. Missiles resulting from ship explosions near the plant.
The following criteria will be met either by eliminating the missile threat by protective measures (as in the case of tornado missiles), or by reducing the probability of missile damage to a very low level, of the order of 10-7 per year as in the case of turbine missiles.
The FNP cesign meets the following criteria: 26
- 1) Protection shall be provided against excessive flooding of the Float-ing Nuclear Plant.
- 2) Protection shall be provided against potential missiles that could cause a LOCA.
Amendment 26 January 3,1979 3.5-5
- 3) Protection shall be provided against potential missiles that could jeopardize functions necessary to bring the reactor to and maintain it at a safe shutdown condition during normal or abnormal conditions assuming a single active failure in the remaining equipment required for shutdown.
- 4) Protection shall be provided against potential missiles that could damage the main steam line isolation valves and the main steam lines between the isolation valves and the containment shell. Similarly, the main feedwater stop valves and the main feed veter lines between the stop valves and the containment shell are piotected from potential missiles.
- 5) Any accident. resulting from an external missile shall not cause off-site exposures in excess of 25% of the guidelines of 10 CFR 100.
l26 fio accidents other than loss of offsite power and those caused by the impact are assumed to occur simultaneous with the missile impact. For the case of tornado and waterspout missiles, multiple missiles (which do not impact at 26 the same location) are considered as the design basis. A single active fail-ure is also assumed.
Protection agains6 a potential missile may be provided by, but not necessar-ily be limited to, any one or combination of the following protection methods:
- 1. Compartmentalization Enclosure of the missile source or the equipment requiring protection in compartments whose walls prevent penetration by the missile.
Amendment 26 January 3,1979 3.5-6
- 2. Barriers - Erection of missile barriers either at the missile source or at the equipment to be protected.
- 3. Separation - Sufficient separation of redundant systems in a safety network so that a potential missilp cannot damage both redundant sys-tems and prevent safe shutdown of the plant.
- 4. Distance - Location of equipment beyond the range of a potential missile.
- u. Equipment Design - Design equipment to withstand impact of potential missile without loss of function.
10 Method 2 (barriers) will be the primary method used for protection against external missiles.
Figures 3.5-2 through 3.5-10 show the areas of the plant protected from postu-lated missiles originating outside the plant. Wi thin this protection " envelope" are all systems and components required to achieve and maintain safe shutdown assuming a coincident loss of offsite power. The barriers shown on Figures 3.5-2 through 3.5-10 will withstand any missiles originating outside the plant.
Characteristics of missiles originating outside the plant are discussed in Sections 3.5.3, 3.5.5 and 3.5.7. Missiles generated within the plant and ex-ternal to the containment are discussed in Sections 3.5.4 and 3.5.6.
Amendment 10 July 19, 1974' 3.5-7
3.5.3 Tornado and Waterspout Missiles The full spectrum of potential tornado missiles falls into two categories, penetrating type missiles and impact missiles. The penetrating-type missiles are characterized by relatively high velocity and small area of impact and have their primary effect on the target structure by penetration. Impact-type missiles are characterized by relatively large mass and have their pri-mary effect on the structure by impulse loading.
It is assumed in a tornado strike that multiple external missiles (which do not 26 impact at the same location) can strike the plant. Analyses to determine the extent to which missiles generated by tornados and waterspouts may be a hazard to the Floating Nuclear Plant are based on the maximum tornado described in subsection 3.3.2. As indicated in subsection 3.3.2, and as estimated by water-spout researchers (Appendix 20), use of the design basis tornado is highly conservative.
Potential sources of missiles which are of hazard to the plant are:
- 1. loose materials on and structural components of the FNP itself;
- 2. small boats and bargcs within the breakwater and loose material or components which may 'oe carried on these crafts;
- 3. pieces of flotsam or hurricane debris which may be washed up on the breakwater.

- 14. This guide (or the latest revision to the guide, as appropriate) will be addressed during the final design approval phase.
- 15. Guide withdrawn by the NRC.
- 16. The Plant Design Report was prepared in accordance with the original version of Regulatory Guide 1.70 and was filed shortly after publica-tion of Revision 1 to Regulatory Guide 1.70. Regulatory Guides in the 1.70.x series further modify Regulatory Guide 1.70 (Revision 1) to in-corporate additional information required in safety analysis reports.
Information required by these guides, and appropriate to the manufactur-ing license application, has been provided by the Applicant in response to Staff requests for additional information.
- 17. Flood studies for each site will be provided in the owner's application.
The following clarification pertains to the application of Regulatory Guide 1.59 to the FNP site envelope. The FNP is inherently protected from floods because the plant floats. Only during the postulated sinking emer-gency is the plant vulnerable to damage from flood. The non-mechanistic sinking emergency is a very unlikely event; therefore, the site envelope postulates the combined occurrance of sinking and a flood-producing event of 100 year severity (See Table 2.1-1 and Section 2.3).
- 18. The Applicant adopts the regulatory positions with the following clarif-ications and exceptions.
Post-Accident Monitoring (PAM) instrumentatica will be provided to mon- 26 itor key NSSS & B0P system parameters, the containment conditions, and the effectiveness of the Engineered Safety Features. The instrumentation supplied will provide the operator with information to enable him to per-form manual safety functions and to determine the effect of normal safety actions taken following a Condition II, III or IV event. PAM instru-mentation will be qualified in accordance with the final NRC-staff-approved version of the Westinghouse Topical Report, WCAP-8587.
Recorders will be provided for certain accident monitoring channels. Of those parameters selected to provide transient or trend information to the operator, at least one of the redundant accident monitoring channels is recorded. The recorder is not redundant, does not meet the single-failure criterion, does not have its own isolation amplifier (the in-com1r,g signal will already be isolated from the accident monitoring channel) and may have multiple pens to permit more than one channel to be recorded. The equipment in the environmental and seismic qualification program includes these recorders. These recorders will not be qualified to function during the postulated seismic event. Following the event, the recorders will regain an operating status.
Amendment 26 January 3,1979 3D-ll
APPENDIX 3D NOTES TO DIVISION 1 REGULATORY GUIDE (CONT)
When monitored parameters that are required for both norma ~ operation and accident monitoring are displayed on ore than one indicator, the indi-cators will be identical. This will achieve the operator familiarity intended by the position.
PAM instrumentation will be prWided as stated above; however, the instrument ranges delineated ir Position C.3 extend far beyond the worst expected values of measured pasameters following a design basis event.
The applicant therefore does not propose to supply instrumentation to satisfy these extended range requirements. The applicant believes that Position C.3 should be deleted or modified to require instrument ranges that correspond to credible worst case conditions. For example, the range for containment pressure is typically 115% of the plant's contain-ment design pressure.
- 19. The Applicant adopts the regulatory positions with the following clarif-ications.
Sufficient margin will be provided between the allowable technical specif-ication limit for the process variable and the nominal trip setpoint to account for drift of the setpoint as measured at the instrument rack during periodic testing. This margin is documented in the technical 26 specifications. The additional margin required to allow for uncertain-ties in the calibration and environmental effects on instrument accuracy caused by limiting postulated events (if applicable) is included in the allowance between the technical specification limit and the value assumed for the accident analysis.
Instruments will be selected based on expected normal and accident en-vironmental conditions. Therefore, setpoint locking devices will not ordinarily be supplied. The need for qualification testing will be evaluated and justified on a case basis.
Instruments are considered to be secure from unauthorized setpoint changes by personnel if the setpoint adjustment mechanism is located within an enclosed, locked cabinet with access to the cabinet under administrative control. In this case the instrument cabinet serves as a common securing device for all setpoint. adjustment mechanisms contained within.
- 20. The Applicant reserves comittment to the NDRC formula for concrete penetration (suggested in the Regulatory Guide) until the EPRI-sponsored missile tests have been completed and evaluated.

APPENDIX 30 NOTES TO DIVISI0ft 1 REGULATORY GUIDE (CONT)
- 21. The Applicant adopts the following position of Westinghouse, the steam generator vendor. This position has been approved by the NRC in the RESAR 414 Safety Evaluation Report.
Position C.1 The term " unacceptable defects" is interpreted to apply to those imper-fections resulting from service-induced mechanical or chemical degrada-tion of the tube walls which have penetrated to a depth in excess of the plugging limit.
Westinghouse has documented its opinions on Regulatory Guide 1.121 by corporate letter and has identified as the major exception the margin of 3 against tube failure for normal operation. Westinghouse defines tube failure as plastic deformation of a crack to the extent that the sides of the crack open to a non-parallel, elliptical configuration.
The tubing can sustain added internal pressure beyond those values be-fore reaching a condition of gross failure. Westinghouse interprets this to apply as an operating limit for the plant and considers that it introduces a conflict to the established conditions for plant 26 operation as identified in the plant tech specs. A factor of 3 is quite often used in ASME Code Design guidelines. These Code practices apply to the design of hardware and to the analyses done on these designs.
Conditioris which occur during operation of the equipment and which may affect the equipment so that design values no longer apply, are not di-rectly addressed by the initial Code requirements. That is one reason why plant tech specs have been generated to establish safe limits of operation for power station equipment. The ASME Code is not applicable to the operational criteria of steam generator tubing. The Westinghouse tubing design and tubing in the design condition has margins in excess of 3. In summary, Westinghouse satisfies the margin of I when it is used in a Code sense as in new equipment design. Moreover, Westinghouse does not beli eve that this margin should be utilized as a limiting con-dition for normal operation.
Position C.2.b In cases where sufficient inspection data exist to establish a degrada-tion allowance, the rate used will be an average time-rate determined from the mean of the test data.
Position C.3.d(l) and C.3.d(3)
The combined effect of these requirements would be to establish a maxi-mum permissible primary-to-secondary leak rate which may be below the threshold of detection with current methods of measurement. Westinghouse has determined the maximum acceptable length of a through-wall-crack based on secondary pipe break accident loadings which are typically twice the magnitude of normal operating pressure loads. Westinghouse will use a leak rate associated with the crack size determined on the basis of accident loadings.
Amendment 26 January 3,1979 3D-llb
APPENDIX 3D NOTES TO DIVISION 1 REGULATORY GUIDE (CONT) 0 Position C.3.e(6)
Computer code names and references will be supplied rather than the actual codes.
Position C.3.f(l)
A minimum acceptable tube wall thickness (Plugging Limit) will be estab-lished based on structural requirements and consideration of loadings, measurement accuracy and, where applicable, a degradation allowance as discussed in this position and in accordance with the general intent of this guide. Analyses to determine the maximum acceptable number of tube failures during a postulated condition are normally done to entirely different bases and criteria and are not within the scope of this guide.
Position C.3.f(4)
Where requirements for minimum wall are markedly different for different areas of the tube bundle, e.g., U-bend area versus straight length in Westinghouse designs, two plugging limits may be established to address the varying requirements in a manner which will not require unnecessary plugging of tubes. 26
- 22. The Applicant adopts the regulatory positions with the following clarifi-cations and exceptions.
- a. The Regulatory Guide states in paragraph B.l(b): " Allowable service limits for bolted connections are derived from tensile and shear stress limits and their non-linear interaction; they also change with the size of the bolt. For this reason, the increases permitted by NF-3231.1, XVII-2110(a), and F-1370(a) of Section III are not directly applicable to allowable shear stresses and allowable stresses for bolts and bolted connections",
and in paragraph C.4: "This increase of level A or B service limits does not apply to limits for bolted connections."
As noted above, the increase in bolt allowable stress under emerg-ency and faulted conditions is not permitted. The applicant be-lieves that the present ASME Code rules are adequate for bolted connections. This position is based on the following:
It is recognized after extensive experimental work by several researchers that the interaction curve between the shear and tension stress in bolts is more closely represented by an ellipse and not a line. This has been clecrly recognized by the ASME.
Code Case 1644-6 specifies stress limits for bolts and represents this tension / shear relationship as a non-linear interaction equa-tion (incorporated into ASME III Appendix XVII via the Winter 77 Amendment 26 January 3,1979 3D-llc
APPENDIX 30 NOTES TO DIVISION 1 REGULATORY GUIDE (CONT)
Addendum) and has a built-in safety factor that ranges between 2 and 3 (depending on whether the bolt load is predominantly tension or shear) based on the actual strength of the bolt as determined by test (Ref:
" Guide to Design Criteria of Bolted and Riveted Joints," Fisher and Struik, copyright 1974, John Wiley and Sons, Page 54).
Study of three interaction curves of allowable tension and shear stress based on the ASME Code (emergency condition allowables per XVII-2110 and faulted condition allowables per F-1370) and the ulti-mate tensile and shear strength of bolts (obtained from experimental work published by E. Chesson, Jr. , N. L. Faustino, and W. H. Munse, "High Strength Bolts Subjected to Tension and Shear," Journal of the Structural Division, Proceedings of the American Society of Civil Engineers, October 1965, Pages 155-180) indicates that there is ade-quate safety margin between the emergency and faulted condition allow-ables and failure of the bolts.
During their tests to determine the strength and behavior character-istics of single high strength bolts subjected to various combina-tions of tension and shear (T-S), Cnesson, et. al. used a total of 115 bolts to ASTM specification A325-61T and A354-Grade BC. The A325-61T, which is a medium carbon steel, had a yield point of 77000 26 psi to 88000 psi and ultimate strength of 105000 psi to 120000 psi, depending upon the bolt diameter. The A354-Grade BC, which is a heat treated carbon steel, had a yield point of 99000 psi to 109000 psi and ultimate strength from 115000 psi to 125000 psi, again depending upon the bolt diameter.
Figure 30-1 shows the interaction curves for T-S loads on SA325 bolts.
Curve (1) represents the interaction relation (ellipse) permitted by Code Case 1644 (ASME III Appendix XVII Winter 77 Addenda) for service levels A, B and design condition. Curve (2) represents the interaction curve which considers the Code Case 1644 allowables and the increase permitted by XVII-2110(a) for service level C. Curve (3) represents the interaction curve which considers the Code Case 1644 allowables and the increase permitted by F-1370(a) for service level D. Curve (3) is the upper limit of the allowable ttresses.
The design stress limits represented by Curves 1, 2, and .' for A325 bolts are then compared against the ultimate strength of the bolts represented by Curve 4, which is based on Chessoi:'s test results.
The area between Curve 3 and Curve 4 is the safety margin between the maximum bolt stress under service level D and minimum ultimate strength of the bolt.
Factor of safety against failure for A325 bolts for various T-S ratios is shown in Figure 30-2. The safety factor varies between a minimum of 1.36 and a maximum of 2.29 depending upon the value Amendment 26 January 3,1979 3D-11d
APPENDIX 3D NOTES TO DIVISION 1 REGULATORY GUIDE (CONT) of T-S ratio. This is based upon the ultimate strength of the bolts from Chesson's test and the allowables obtained from Code Case 1644 and the increase permitted by F-1370(a) for service level D. Figure 3D-2 demonstrates that there exists an adequate factor of safety for the complete range of T-S loadings.
From this study it is observed that:
(1) For the emergency condition, the safety factor (ratio of ulti-mate strength to allowable stress) varies between a minimum of 1.63 and a maximum of 2.73 depending upon the actual tensile stress / shear stress (T/S) ratio on the bolt.
(2) For the faulted condition, the safety factor varies between a minimum of 1.36 to a maximum of 2.29, again depending upon actual T/S ratio on the bolt.
It is thus reasonable to allow an increase in these limits for the emergency and faulted conditions.
Based on the above discussion, for the emergency and faulted con- 26 ditions, the applicant will use allowable bolt stresses specified in Code Case 1644-6, as increased according to the provisions of XVII-2110(a) and F-1370(a), rMpectively.
- b. The increased de; sign limit for the stress range identified in NF-3231.1(a) shall be limited to the smaller of 2 Sy or Su unless other-wise justified by shakedown analysis.
- c. In paragraphs B.5 and C.8 of the Regulatory Guide, the applicant takes exception to the requirements that systems whose safety-related function occurs during emergency or faulted plant conditions must meet level B limits. The reduction of allowable stresses to to no greater than level B limits (which in reality are design limits since design, level A and level B limits are the same for the linear supports) for support structures in those systems with safety related functions occurring during emergency or faulted plant conditions is overly conservative. The primary concern is that the system remains capable of performing its safety function. For active components, this is accomplished through the operability program as discussed in Section 3.9.2.4. In the case of Class 1 piping, maintaining the pipe stresses within level D limits assures that piping geometry is maintained and that required flow is not impeded. The selection of more restrictive stress limits for component supports is not necessary to assure the functional capability of the system.
Amendment 26 January 3,1979 3D-lle
APPENDIX 30 NOTES TO DIVISION 1 REGULATORY GUIDE (CONT)
- d. Paragraph C.4 of the Regulatory Guide states: "However, all increases (i.e. , those allowed by NF-3231.l(a), XVII-2110(a),
and F-1370(a)) should always be limited by XVII-2110(b) of Section III". Paragraph XVII-2110(b) specifies that member com-pressive axial loads shall be limited to 2/3 of critical buckling.
In the design of component supports, member compressive axial loads shall be limited to 0.67 times the critical buckling strength.
If, as a result of more detailed evaluation of the supports the member compressive axial loads can be shown to safely exceed 0.67 times the critical buckling strength for the faulted condition, verification of the support functional adequacy will be documented and submitted to the NRC for review. The member compressive axial loads will not exceed 0.67 times the critical buckling strength without NRC acceptance. In no case shall the compressive load exceed 0.9 times the critical buckling strength.
- e. Paragraph C.4 of the Regulatory Guide states that increases in Level A or B service limits does not apply to limits for bolted connections. The applicant's design of component supports re-stricts the use of bolting material to the following applications: 26 (1) Bolting is predominantly in tension. Oversized holes are generally provided and a mechanism other than the bolts is provided to take any shear loads. Shear or shear & tension interaction occur only in isolated locations; (2) Bolts are limited to the following material A490, SA-354, SA-325, SA-540.
(3) The diameters used range between 1/2" and 3".
These limitations on bolt usage are standard in the applicant's supports. We will limit tensile loads in the bolts to 0.7 Su, but not to exceed in any case 0.9 Sy. The allowables are taken at temperature. In those few cases where bolts are used in shear or tension and shear, ASME Code Appendix XVII - 2460 Requirements will apply with an increase factor that is defined in Regulatory Guide 1.124 or in Appendix F-1370, whichever is more restrictive. This provides an adequate margin of safety for the applicant's design.
If future revisions to the bolting criteria in ASME Section III modify the applicant's criteria listed above, we will review the criteria at the time.
- f. Paragraph C.6(a) of the Regulatory guide appears confusing as to what stress limits may be increased for the emergency condition. The applicant will interpret this paragraph as follows: "The stress Amendment 26 January 3,1979 3D-ll f
APPENDIX 30 NOTES TO DIVISION 1 REGULATORY GUIDE (CONT) limits-of XVII-2000 of Section III and Regulatory Position 3 increased accordirig to the provisions of XVII-2110(a) of Section III and Regula-tory Position 4, should not be exceeded for component supports de-signed by the linear elastic analysis method."
- g. The method described in Paragraph C.7(b) of the Regulatory Guide is overly conservative and inconsistent with the stress limits presented in Appendix F. The applicant will use the provisions of F-1370(d) to determine service level D allowable loads for supports designed by the load rating method. If future revisions to Appendix F modify this criteria, it will be reviewed further. If the load rating method is used, further details of its implementation will be pro-vided at that time.
- 23. The Applicant adopts the regulatory positions with the following clarifica-tions and exceptions,
- a. The applicant will use the latest revision of Code Case 1644 as approved by Regulatory Guide 1.85.
- b. Paragraph B.1 states that increases are not allowed for bolted con-nections for emergency and faulted conditions. The applicant's 26 position is that it is reasonable to allow an increase in the limits for bolted connections for these conditions. Further justification concerning this position can be found in Item a of the discussion on Regulatory Guide 1.124.
- c. Paragraphs C.3, C.4(a), and C.6(a) state that the allowable buckling strength should be calculated using a design margin of 2 for flat plates and 3 for shells for normal, upset, and emergency conditions.
In the design of plate-type supports, member compressive axial loads shall be limited per the requirements of Paragrapn C.3 for normal upset, and emergency conditions.
- d. In paragraph C.7, the inclusion of the upset plant condition in this load combination is inappropriate. The upset plant conditions are properly considered in paragraph C.4.
- e. Paragraph C.7(a) references the criterion presented in F-1370(c),
which states: " ... loads should not exceed 0.67 times the critical buckling strength of the support...".
In the design of plate-type component supports, member compressive axial loads shall be limited to 0.67 times the critical buckling strength. If, as a result of more detailed evaluation of the supports the member compressive axial loads can be shown to safely exceed 0.67 Amendment 26 January 3,1979 3D-11g
APPENDIT 3D NOTES TO DIVISION 1 REGULATORY GUIDE (CONT) times the critical buckling strength for the faulted condition, veri-fication of the support functional adequacy will be documented and submitted to the NRC for review. The member compressive axial loads will not exceed 0.67 times the critical buckling strength without NRC acceptance. The applicant has no Class 1 shell-type supports.
- f. The method described in paragraph C.7(b) of the Regulatory Guide is overly conservative and inconsistent with the stress limits presented in Appendix F. The applicant will use the provisions of F-1370(d) to determine service level D allowable loads for supports designed by the load rating method.
- 24. The basis as well as the scope of the Guide for predicting adjustment of reference temperature as given in Regulatory Position C.1 are not appropri-ate since the data base used was incomplete and included some data which were not applicable.
The Applicant is in agreement with the Position C.2a. However, with re-spect to Position C.2b, the Applicant believes that Figure 2 is incorrect since the upper shelf energy for six-inch thick ASTM A302B reference correla-tion monitor material reported by Hawthorne indicates essentially a constant upper shelf at fluences above s 1 x 1019 n/cm2.1/ 26 With reference to the guide Position C.3, the stresses in the vessel can be 'imited during operation in order to comply with the requirements of Appendix G to 10CFR Part 50 even though the end-of-life adjusted reference temperature may exceed 200 F. By applying the procedures of Appendix G to ASME Section III, the stress limits including appropriate Code safety margin can be met, and it is not necessary to control residual elements to levels that result in predicted adjusted reference temperature of less than 200 F at end-of-life.
As an alternative to Regulatory Guide 1.99, operating limits for the Floating Nuclear Plant will be determined by using the current radiation damage curves given in Figure 3D-3 (reproduced from RESAR-3S). Recent surveillance capsule data indicate that after an initial increase RTNDT e with increased fluence and that the Westinghouse curves NDT are conservative._2 /

5.2 INTEGRITY OF THE REACTOR COOLANT SYSTEM PRESSURE BOUNDARY Section 5.2.2 and 5.2.3 are presented in RESAR, information for the four loop plant without stop valves is applicable. The following information supplements section 5.2.2:
Each of the three pressurizer safety valves is set at 2485 psig and reaches full relief flow of 420,000 lbs/hr at 3;; accumulation. These valves to-gether will accomodate a maximum 50!; load change without reactor trip.
5.2.1 Design Criteria, Methods and Procedures Section 5.2.1 of RESAR is modified herein to cover the wind and wave effects for stress analyses including fatigue evaluation. The basic modification is in the areas of design condition, loading and stress combinations. The Floating nuclear Pcwer plants are subject to platform motion caused by wind and wave in addi tion to earthquake as for land plants. The combined operating basis environmental transients (C) and design basis environmental transients (Cs) are defined in 3.7.1.1 and the magnitude and occurence of each event are sumarized in Tables 3.7.1-2 and 3.7.1-4. For the Reactor Coolant System, towing will be treated conservatively as an upset condition. These environ-mental transients unique to the Floating Nuclear Plants will be included within the analyses and by the computer programs which were applied to the basic RESAR design.
Amendment 12 November 5,1974 5.2-1
Methods of stresa analysis for the faulted condition are discussed in RESAR 5.2.1.3 and Appendix F of the ASME B and PV code section III. The elastic O system analysis and elastic components analysis method will be generally used for the Floating Nuclear Plant. Other methods if used will be described and documented in the permanent plant file. Stress limits for the faulted condition are presented in Table 5.2-8 which is consistent with Appendix F.
In addition, allowable stresses for class 1 components consistent with the ASME Code section III are presented in Table 5.2-5. Class I supports and associated fasteners will be designed to ASME Section III Subsection NF and 26 Appendix F to the ASME Code, except that the provisions of USNRC Regulatory Guides 1.124 and 1.130, adopted as modified in Appendix 3D to the PDR, shall apply.
Tables 5.2-2, 5.2-4, 5.2-5, and 5.2-8 of RESAR are suitably modified for the 26 Floating Nuclear Plant and are included in this report. Table 5.2-4 includes explicitly the plant transients, the relief valve and fast valve operations, and the environmental transients in the loading combinations.

Amendment 12 0-xiv November 3,1974
Smoke Detection Ventilation systems are provided with smoke detectors as shown on the flow diagrams. Audible and visual alarm is given in the control room. Systems are either shutdown when smoke originates outside the space or placed on a venting mode when smoke originates inside the space except the control room and emergency relocation areas, which are placed on limited minimum outside air intake mode utilizing HEPA and charcoal filters in all cases, including isolation signal or smoke signal. See Smoke and Survival Protection in Sec-tion 9.4.1.2 and Table 9.4.1-5 for limited minimum outside air intake and system air flows.
Regulatory Guide and Branch Technical Position Compliance flon-ESF HVAC Systems are designed to be in compliance with BTP ETSB 11-2,
" Design Testing, and Maintenance Criteria for Normal Ventilation Exhaust System Air Filtration and Adsorbtion Units of Light Water Cooled Nuclear Power Reactor Plants."
The ESF Air Filtration Systems of tne Floating Nuclear Plant which come within 26 the scope of Regulatory Guide 1.52 are:
- 1. Control room
- 2. Emergency relocation area (ERA)
- 3. Fuel pit exhaust
- 4. Annulus air filtration
- 5. Containment purge exhaust 26 Amendment 26 January 3,1979 9.4-2a
These systems are designed to be in compliance with Regulatory Guide 1.52 with the following exceptions.
Paraaraoh 2a All systems are designed redundant with the exception of ducts. This has been accepted industry practice in the past. The ducts on the ESF Systems are designed and/or protected from all credible internal and external events.
Consequently, since ducts are passive elements, the systems are not designed to account for duct failure.
Paragraph 2b Redundant atmosphere cleanup systems are protected from externally generated missiles by placing the systems within protected areas of the plant. On 26 exception is the Fuel Building Ventilation System downstream of the filtration trains. This portion of the Fuel Building Ventilation System is not missile protected because the Design Basis Fuel Handling Accident concurrent with a tornado is not credible. Secondly, the Annulus Air Filtration System downstream of the exhaust fans is not missile protected because Post-LOCA Recovery concurrent with a tornado is not credible.
Furthermore, redundant atmosphere cleanup systems are located and/or designed to preclude local phenomena from impairing their design capabilities.
Paragraph 2f It is the Applicant's understanding that the 30,000 CFM approximate limitation exists for two reasons. One is to limit the air flow rate for testing purposes and Amendment 26 January 3,1979 9.4-2b
another is, for ease of maintenance, to limit the number of filters to 10 wide by 3 high ultilizing 1000 CFM HEPA filters.
The volumetric flow rate of a single cleanup train in the FNP design is limited to 36,000 CFM. This exception is justified for the following reasons:
From a testing point of view the 30,000 is predicated on the practical limitations of Laskin nozzle air operated D0P generators, however Gas-Thermal DOP generators are available which produce adequate D0P concentration for air flows up to 50,000 CFM. From a maintenance point of view, by utilizing 1500 CFM HEPA filters, the plant design reduces the number of filter cells from the 30 mentioned in Regula-tory Guide 1.52 to 24. When filter height is greater than three filter cells an internal maintenance platform with separate external access is provided.
Paragraph 29 The pertinent pressure drops and flow rates are instrumented to signal and alarm in the Control Room. However, recording of these pressure drops and flow rates does not provide any additional information which would aid the safe operation of the plant. Therefore, recording of these signals is not considered a design requi rement.

EflCLOSURE 3 BRANCH TECHNICAL p0 SIT!CN DSB 5-2 OVERPRE55URIZATION PROTECTION OF PRESSURIZED WATER REACTORS Wil!LE OPERATIflG AT LOW TEMPERATURES A. Backnruund General Design Criterion 15 of Appendix A, 10 CFR 50, requires tha t "the Reactor Cnolant System and associa ted auxiliary, ccntrol, and protection systems shall be designed with sufficient ra. gin to assure tha t the design conditions of the reactor coolant cressure boundary are not exceeded during any condition of norma.1 operation, including anticipated operational occurrences."
Anticipated operational occurrences, as defined in Apoendix A of 10 CFR 50, are "those conditions of normal oceration wnich are expected to occur cne, or more times during the life of the nuclear pcwer unit and include but are not limited to loss of power to all recirculation pumps, tripping cf the turbine generator set, isolation of the main condenser, and loss of all of fsi te power."
Aopendix G of 10 CFR 50 provides the fracture toughness reouireirents for reactor pressure vessels under all conditions. To assure that the Aonendix G limits of the reactor coelant pressure boundary are not exceeded durino any anticipated Opera tional occurrences , Technic 31 Specification pressure-temperature limits are provided for operating the plant.
The primary concern of this position is that during startup and shutdown e.ondi tions a t low tempera ture , especially in a wa ter-solid condi tico ,
the reactor coolant system cressure might exceed the reactor ve3sel pressure-temperature limitations in the Technical Specifications established for crotection egainst brittle fracture. This inadvertent overpressuri:ation could be generated by an;. one of a variety of mal-functions or operator errors. Many incidents have occurred in operating plants as described in Reference 1.
Additicnal discussion on the background of this position is contained in Reference 1.
B .18.1 -5 Amendment 26 January 3, 1979
EfiCLOSUFE 3 B. Granch Pusi tion
- 1. A* system should be desiqned and installed which will prevent exceeding the acclicable Technical Scecifications and Appendix G limits for the reactor coolant system wnile operaticn ac !cw temperatures. The system should be c3pable of relieving ressure during all anticipated overcressurization events at a rate suf ficient to satisfy the Technical Specification limits, particularly while the reactor coolant system is in a water-solid condition.
- 2. The system must be able to perform its function assuming any single active component failure. Analyse; using accropriate calcula tional techniques mus t be provided wnich demons trate tha t the sys tem will provide the required pressure relief capacity assuming tl'e most, limiting single active failure. The cause for initiation of' the event, e.g. , operator error, ccmpenent mal function, will not be considered as the sirigle active f ailure. The analysis sFculd assunte the ecst limiting allowable operating conditions and systems configuration at the time 'of the pcs tulated cause of the overoressure event. All potential everpressuri:ation events must be censidered when establishing the worst case event. 3 cme events may be prevented by protective interlocks or by locking cut cower, these events should he reviewed on an individual basis. !f the interlock / power loc'<out is acceptable, it can be excluded frcm the analyses provided the controls to prevent the event are in the plant Technical Specifications.
- 3. The system must meet the design requirements of IEEE 279 (see Impl emen ta t ion) . The system may be -anually enabled, hewever, the electrical ins trumenta tion and control system must provide alarms to alert the operator to:
- a. Drocerly enable the sys tem at the correct plant condition during cooldcwn,
- b. indicate if a pressure transient is occurring.
- 4. To assure operational readiness, the overpressure proteccion system must be tested in the following manner:
- a. A test must be perferred to assure operability of the system electronics prior to each shutdown,
- b. A tast for valve cperability must, as a minimum be conducted as specified in the ASME Code Section x[.
- c. Subsequent to system, valve, or electronics maintenance, a tes t on that portion (s) of the system must be performed prior to declaring the system operational.

Amendment 26 January 3, 1979 B.18.2-2
NRC Document flumber/ Revision Response BTP RSB 5-1/1 A. Functional Requirements The following changes will be made to the FNP to comply with the stated functional requirements:
- 1. The control system on the atmospheric power operated relief valves in the main steam system will be upgraded to Class lE.
- 2. a) The controls for the two pressurizer power-operated relief valves will be upgraded to Class lE, or b) The controls for the a Wiliary pres-surizer spray valve will be upgraded to Class lE. To accommodate a single failure in the auxiliary pressurizer spray line, the necessary parallel piping and valves will be added to the spray line, or_ the controls for at least one of the two pressurizer power-operated relief valves will be upgraded to Class lE. 26 With these changes, the design of the FNP will be such that the reactor can be taken from normal operating conditions to cold shutdown in conformance with the NRC Branch Position. Boration can be provided by the Safety Injection System from the Boron In-jection Tank and the Refueling Water Storage Tank.
B. RHR System Isolation Requirements
- 1. The suction side of the RHR system meets the stated isolation requirements. Two motor operated valves in series are pro-vided in each suction line, with opera-tion from and position indication in the control room. Pressure interlocks are provided on these valves to prevent their opening, or to close them, if the Reactor Coolant System pressure is above the RHR design pressure. No single failure will prevent isolation of the RHR suction lines.
The interlocks are redundant but not di-verse. OPS believes interlock diversity is not necessary to accomplish the in-tended isolation function.
Amendment 26 January 3,1979 B.18.2-3
NRC Document Number / Revision Response BTP RSB 5-1/1 (Cont'd) 2. The discharge side of the RHR system is isolated by two check valves in series. Design provisions are in-included to pennit periodic leak tightness testing of these valves.
These check valves are part of the Safety Injection System and are shown in Figure 6.3-1, Sheets 2 and 3.
C. Pressure Relief Requirements (in RHR System)
Each RHR System suction line incorporates a pressure relief valve in accordance with the NRC Branch Position.
D. Pump Protection Requirements The FNP design meets the stated require-ments.
E. Test Requirements The FNP design meets the stated require- 2 ments. R.G. 1.22 and R.G. 1.68 are ad-dressed in Appendix 30. We expect that the requirement for tests and analyses to confirm adequate mixing of borated water and natural circulation will be met by comparison with performance of pre-viously tested plants of similar design.
F. Operational Procedures This is in the utility-owner's scope.
R.G. 1.33 is addressed in Appendix 30.
G. Auxiliary Feedwater Supply The FNP design meets the stated require-ments. Refer to Section 10.4.6.7.
Arrendment 26 January 3,1979 B.18.2-4
NRC Document Number / Revision Response BTP RSB 5-2/0 -Administrative procedures are developed to aid the operator in controlling RCS pressure during low temperature operation. However, to provide a backup to the operator, an auto-matic system will be provided to comply with NRC Branch Technical Position RSB 5-2. The Applicant is evaluating design alternatives (including the use of pressurizer power oper-ated relief valves as described in the SNUPPS application and RESAR-414) and will submit 26 design modifications as part of the final plant design. As agreed in Mr. H.R. Denton's letter of December 22, 1978, a comitment by Offshore Power Systems on a generic issue such as this is adequate for the Manufacturing License.
