1.0 INTRODUCTION

CONTAINMENT VESSEL DESIGN

SUMMARY

REPORT This report has been prepared for the Atomic Energy Commission by the G,meral Electric Company. Its purpose is to provide technical information on the design of the containment vessel. It describes design and leak test criteria and methods and contains code forms and leak test results.

Previously submitted material has generally not been duplicated and where possible, references to this material have been included.

The containment vessel consists of a drywell and pressure suppression chamber, with a vent system connecting them. Nume:-ous previously submitted documents contain diagrams of the system. A reactor building encloses the containment vessel and acts as a secondary con-tainment when the containment vessel is in service. Both the containment vessel (primary containment) and the reactor building are described in Section 5 t The drywell is a light-bulb shaped vessel with the spherical.portion at the bottom and with the top cylindrical portion closed by a removable, flanged head *

• The top head is of a type that can be easily opened. Details are such that all bolts are removable with the head and arranged so that they may be tightened using an impact wrench. A 24 inch diameter inspection opening is provided in the head. The top head closure and the inspection opening have been made leak tight by means of double compression seals with con-nections to permit leak testing by pressurizing the air space between the seals.

The suppression chamber is in the general form of a torus; however, in lieu of furnishing a double curved surface, the vessel is made up of 16 mitered cylindrical sections. Baffles, catwalks with steel grating floor and two manholes with ladders to the catwalks were provided.

Manholes are flanged and bolted with .a double compression seal with connections to permit leak testing by pressurizing the air' space between the seals. Catwalks are capable of supporting a live load of 50 psf.

The vent system interconnecting the drywell and suppression chamber consists of vents between the drywell and a common header located within the suppression chamber, and down-comer pipes from the header terminating below the normal water level in the suppression chamber.

There are 8 vents equally spaced and uniformly sloped between the drywell and suppression chamber. Joints, permanently accessible, are provided in each vent to allow for relative movement due to expansion and contraction and other differential movements which may occur between the containment vessels. The common header for the vents is also in the general form of a torus and is also made up of 16 mitered cylindrical sections .

• F. lr-1 REV 4 12/85

MONTICELLO The downcomer pipes are arranged so that there are 4 in panels with vents and 8. in panels without vents. Each downcomer has an outside diameter of 24 inches and a wall thickness of 1/4". The downcomer pipes terminate 4. 0 ft below the minimum water level in the suppression chamber.

The sizes and arrangements of the drywell, suppression chamber and vent system are shown on tables and illustrations in: .Section 5 *. The suppression chamber is centered in the basement of the Reactor Building with the vertical axes of the vessels coincident.

• 2. 0 2.1 CONTAINMENT SYSTEM CRITERIA AND DESIGN GENERAL The containment vessel is designed, fabricated and testt:u *- meet applicable codes or standard requirements, in a manner that guarantees without failure the leak-tightness and structural integrity of the system during all modes of plant operation or during any design accident condition. Failure of a containment barrier is defined as any failure which increases leakage rates above permissible values.

2.2 APPLICABLE CODES - PRESSURE VESSELS The design, fabrication, erection and testing cf the vessels conformed to the requirements of the American Society of Mechanical Engineers Boiler and Pressure Vessel Code, Section m Class B, 1965 edition, and all applicable addenda and Code Case Interpretations, including Code Cases 1177 and 1330.

The completed vessels were inspected and marked by a recognized inspection agency certifying that the requirements of the applicable standards and codes hac. been fulfilled. The vessels were stamped with the ASME Boiler and Pressure Vessel Code stamp in a permanently visible location, in accordance with Paragraph N-150C *

• Other - The design, fabrication, and erection of supports and bracing and like applications not within the scope of the ASME Code conformed to the requirements of the Specifications for the Design, Fabrication, and Erection of Structural Steel for Buildings, 1963 edition, of the American Institute of Steel Construction.

2.3 MATERIALS Materials used are in accordance with applicable codes. Plate materials are A212-B FBX and A516-70 FBX to A300. Pipe materials are A333 Gr. 1 seamless, forgings are A350 LF 1, bolts are A320-L7, Al94 Gr 4, and Al93-B8. Miscellaneous materials are A36, A284-B, API-SLX-42, and A283 C.

The suppression chamber also is subject to the pressure associated 3

with the storage of 75, 900 rt of water distributed uniformly within the vessel.

Accident Condition In addition to the specified Design Pressures and Temperatures, the drywell shell and closure head are designed and constructed to withstand jet forces of the following magnitudes in the locations indicated from any direction within the drywell:

Location Jet Force (Max)

Interior Area Subjected to Jet Force Spherical part of crywell 664, 000 pounds 3. 69 sq. ft.

Cylinder and sphere to cylinder transition 256, 000 pounds 1.42 sq. ft.

Closure Head 32,600 pounds 0.181 sq. ft.

The spherical and cyline&"ical parts of the drywell are backed up by reinforced concrete with space for expansion between the outside of the drywell and the concrete.

The above listed jet forces consist of steam and/or water impinging on the vessel causing a maximum metal temperature of 300°F. The jet forces listed above do not occur simultaneously.

However, a jet force was considered to occur coincident with design internal pressure and a temperature of 150 ° F. Where the drywell shell is backed up by concrete it was assumed that local yielding will take place but it was established that a rupture will not occur. Where the shell is not backed up by concrete, the i, ....1ary stresses resulting from this combination of loads did not exceed O. 90 times the yield point of the material at 300°F.

The suppression chamber was designed for the specified Design Pressures & Temperatures coincident with the loads associated with the storage of suppression pool water increased in 3

volume to 83, 700 ft. ~d a jet force on each downcomer pipe of 21 kips.

• Equipment Loads in Drywell The vertical loads of the primary reactor vessel and reactor support concrete and equip-

"'.ent within the drywell were supported directly through the concrete f_ill within the drywell to continuous concrete fill below the drywell.

The design of the drywell in its final support condition included pro,*ision for the seismic shear and moments on the base of the reactor vessel support pedestal.

Gravity Loads Applied to the Drywell Vessel include:

The weight of the steel shell, jet deflectors, vents and other appurtenances.

Loads from equipment support structural members.

An allowance of 10 psf for the compressible material to he temporarily applied to the exterior of the vessel for use as concrete forms.

The live load on the equipment access opening: 20 tons.

The live load for the depth of water on the water seal at the top flange of the drywell with the drywell hemispherical head removed, or loads from refueling seals without head removed.

The weight of contained air during test.

A temporary load due to the pressure of wet concrete to be placed directly against the exterior compressible material attached to the exterior of the drywell and vents as shown on the drawings. It is intended that the concrete be placed at a rate of 18 inches in depth per hour. It is estimated that this rate of placement will result in a radial pressure on the vessel of 250 psf.

Consideration was given to the residual stresses due to the unrelieved deflection of the vessel under this load, applied in successive 3 foot high horizontal bands.

Gravity Loads Applied to the Sl.ppression Chamber include:

The weight of the steel shell including baffles, catwalks, headers, downcomers and other shell appurtenances.

The suppression pool water stored in the vessel.

The temporary load of 200 psf on the horizontal projected areas of the vessel due to the weight of wet concrete and concrete forms to be supported from the vessel during the construction of the floor above. The ASME Code allowable stresses were increased by 33 per-cent for the combination of this temporary load with other concurrent loads.

MONTICELLO Lateral Loads - Wind Load The drywell vessel which was exposed above grade prior to construction of the Reactor Building was designed for wind loads on the projected area of the circular shape in accordance with the height zones below in combination with other loads applicable during this stage with stresses limited to 133% of the ASME Code allowable stresses.

Height above grade (ft.) Wind Load (psf) 0 - 30 15 30 - 100 21 Over - 100 27 Earthquake Loads - Drywell A lateral force equal to the seismic coefficients indicated in Figures F .2 .J and F .2 .2 applied to the drywell permanent gravity loads and a vertical force equal to 4% of the permanent gravity loads were assumed as acting simultaneously with each other and were taken concurrently with the permanent gravity loads, accident pressure conditions and other lateral loads.

Suppression Chamber A horizontal acceleration of 12%g was applied at the mass center of the suppression chamber and combined as stated above with a vertical acceleration of 4%g and the gravity loads, accident pressure, etc.

Suppression Chamber Baffles - Loads

1) Horizontal: 6 psi on full area of each member of baffle, to provide support

. against wave action

2) Vertical: Dead load of baffle members End Connections Designed as slip joints so baffles do not act as ties or struts for suppression chamber shell. End connections designed for up to 50% overstress so baffle connections will fail before any damage can be done to suppression chamber shell.

Vent Thrust The vent pipes and thei_r connections to the drywell, the suppression chamber and the vent header were designed for the following loads :

F.2-4 REV 4 12/85

MONTICELLO

• Normal and Refueling Operation - A force resulting from the differential horizontal and vertical movements between the drywell and suppression chamber due to changes in temperature.

For this condition it was assumed that the drywell temperature is 150°F and the suppression chamber temperature is 50°F.

Initial and Final Test Conditions - A force equal to design pressure times the net area ,:,i the coMecting ring between the vent pipe and the expansion bellows plus a force equal to design pressure times the flow area of the vent pipe.

Accident Condition - Forces similar to those above except the temperature of the drywell was taken as 281 °F.

Header Loads - The weight of the containment cooling headers in the drywell, the spray header in the suppression chamber and the header on the outside suppression chamber were included in the gravity loads to be considered in the design of the vessels. The header outside the suppression chamber was flooded for all loacµng conditions. The spray headers in both vessels were considered as being empty except during the Refueiing" and '\Accident" loading conditions.

MONTICELLO 2.4.4 Stresses - Primary Stresses The enclosure was so designed that primary membrane stresses resulting from the above listed combinations of loads did not exceed those permitted by the Code.

Primary and Secondary Stresses Secondary membrane and bending stresses in the drywell, suppression chamber and vent system resulting from distortions due to specified internal pressure, loads, and temperature were computed. In the calculation of these stresses all resistances to uniform increase in radius were considered. Combined primary and secondary stresses were within_ limits specified in the ASME Boiler&. Pressure Vessel Code.

Earthquake Stresses Stresses under seismic loading did not exceed the ASME Code or the AISC Code allowable stresses. Use of the 1/3 increase that is normally permitted when considering earthquake loads was not required.

2.4.5 Design Reconciliation A design basis review of the drywell identified differences between the seismic acceleration curves shown co

-st in Figures F.2.1 and F.2.2 and those specified in Appendix A, Section A.3 and as stated in USAR Section 6 0

5.2.5.3.1. An engineering review of these differences concluded that results reported in Section 2.4 of this appendix are still valid when the seismic accelerations identified in Appendix A are considered in the analysis.

MONTICELLO 4.0 FIELD REPAIRS

4. 1 INTRODUCTION In January, 1968, a crack was discovered where a shop assembled nozzle penetration insert plate was welded to the drywell shell of the containment vessel. Extensive inspection, magnetic particle testing and metalurgical examinations were undertaken to determine the cause and extent of cracking. -T hese tests revealed the cracking to be the surface type and most of the cracks were found to be in the insert plate heat affected zone on the chamfered edge. The cracks discovered were longitudinal and immediately adjacent to the weld, ranging in depth from approximately 1/32 to 3/16". No subsurface cracking was detected. The major portion of the cracking occurred on the inside surface and was not confined to a particular type or size of chamfered insert plate.

The fabricator of the containment vessel (C. B. &I.) compiled a detailed report on the cracks, evaluation of the cracks, laboratory simulation of the cracks, analysis of the cause of cracking, and laboratory and field tests of the containment vessel and vessel material. Copies of this report are on file at Chicago Bridge and Iron's Oak Brook, Illinois offices and at General Electric's San Jose, California office, as well as the applicant's office. Nineteen copies of this report were unofficially distributed to the Chief, Reactor Project Branch 1, DRL, of the TJSAEC in March, 1968. The cracks, evaluation of the cracks, the above report and weld repair procedures were the subject of an information meeting held with the AEC on March 20, 1968. Because of this extensive reporting, only a summary of the problem and repairs are included as part of this report.

4.2

SUMMARY

A) Surface cracking, ranging in depth from 1/32" to 3/16" was initially detected on January 18, 1968, mostly confined to the inside of the chamfered insert plates. No subsurface cracks were found.

B) An extensive field and laboratory investigation revealed that this cracking occurred as a result of the presence of hydrogen, high residual stresses, discontinuities at the surface, and high hardness. Laboratory tests simulating actual field temperature conditions resulted in similar cracks. It was concluded that such cracking could be prevented by using higher preheat and post heat temperatures which would tend to alleviate all of the above conditions, except the surface discontinuities.

C) A magnetic particle examination was made of all field welds, both inside and outside, subsequent to discovery of this cracking and prior to pneumatic testing of the vessel.

_ D) Cracks were traced out using carbon arc gouging and all cracks were repaired using

_200'" to 300°F preh~at and 200° to 300°F post heat for one hour. Repaired areas were

• . radlographed and magnetic particle examined after at least 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> delay.

F.4-1 REV 4 12/85

MONTICELLO

• E) All repaired and adjacent areas were again magnetic particle examined during the pneumatic test after the vessel had reached 5 psi pressure. No weld repairs were required.

F) All repaired and adjacent areas were again magnetic particle examined after the vessel had reached 26 psi pressure. Again no weld repairs were required.

G) Following the overload and leak rate test of the vessel, a magnetic particle examina-tion was made of all the field welds arowid all insert fittings, both inside and outside, and spot checks were made of main vessel joints. No weld repairs were required.

4. 3 CONCLUSIONS The absence of cracking as evidenced by the extensive magnetic particle testing during and subsequent to the pneumatic testing of the vessel substantiates the adequacy of the procedures developed for examing welds and for making repairs *

• INITIAL OVERLOAD & LEAK RATE TEST REPORT OF THE CONTAINMENT VESSEL MON"'T.CELLO NUCLEAR PROJECT MO~.ICELLO, MINNESOTA INTRODUCTION The Monticello Nuclear Power Project of the Northern States Power Company incorporates a pressure suppression containment system with a drywell having interconnecting vent lines to a suppression chamber. The system is intended to provide a leak resistant enclosure for the nuclear reactor and any steam or gases that may be released. The vessel is of the shape and size as shown on Page F .A-1.

The drywell and suppression chamber were designed, erected

• and tested by Chicago Bridge & Iron Company under a contract with General Electric Company and in accordance with General Electric Company specifications. The containment was designed and constructed in accordance with the rules of Section III of the ASME Code as a class "B" vessel. The containment vessel, consisting of interconnected drywell and suppression chamber, was stamped after completion and testing with the ASME symbol for the design internal rressure and design temperature.

The drywell was constructed on a skirt, but the lower portion was embedded . in concrete prior to the vessel tes*t . However, a Halogen leak test was conducted on all embedded seams to insure their leak tightness prior to this embedding operation.

The suppression chamber was constructed on permanent steel columns with shear ties to resist all horizontal earthquake forces. All plate seams, excluding the embedded portion,

• were accessible for inspection inside and outside before and after the pressure test. All permanent connections were welded in place in the shell of each vessel.

F.A-2 REV 4 12/85

MONTICELLO Since outside weather conditions were severely cold at the time of test, a temporary encasement was built around the vessel. This temporary encasement was made from patented scaffolding and sheets of polyethylene, and its interior was heated to obtain an environment suitable for testing the vessel.

GENERAL PROCEDURE The following test was made: The procedure for the overload test fulfilled the requirements of Section III of the ASME Code including Code Cases 1177-5 and 1330-1 and the latest addenda as of July 1966. The overload test was made with the suppression chamber partially filled with water to the accident condition level (83,700 cubic feet). Both the drywell and suppression chamber were simultaneously pressurized with air to 125% of the design pressure.

The leakage rate test is performed by comparing a pressure in the containment vessel to a pressure in an inner chamber which is an integral part of the reference system. The reference system was tested with a Halogen leak detector and an absolute pressure test was conducted for 39 hours4.513889e-4 days <br />0.0108 hours <br />6.448413e-5 weeks <br />1.48395e-5 months <br /> prior to the leakage rate test.

The drywell and suppression chamber were tested for leaks in accordance with General Electric Specification No. 21A5642.

A general description of the reference system type of leakage test is as follows: By locating the inner chamber inside the drywell and inside the suppression chamber approximately at the center of the individual air masses, the average temperature of each air mass can be proportionately represented. Previous tests have shown that the data of successive midnight to dawn periods can be compared due to relatively uniform temperature conditions during this period.

F.A-3 REV 4 12/85

MONTICELLO The negligible difference in average air temperature between the inner chamber and the containment vessel eliminates the possibility of a pressure differential being caused by temperature. With the reference system tested, any relative decrease in containment vessel pressure must be considered as external leakage. A manometer is used as the pressure differential sensing device between the reference system and the vessel. Page F.A-4describes the relationship between the differential pressure measurements to the per cent leakage.

Interior measurements of dew point and air temperatures were made and included in the calculation of the leakage rate.- The results of the test are shown in Appendix F.A.E.

• PRELIMINARY INSPECTION AND TESTING Before the overload and leakage rate test at Monticello, preliminary inspection and testing was performed in the shop and field. All shop welded manholes and nozzles were magnetic particle inspected after stress relief. The personnel lock was shop assembled and tested for structural adequacy. A leak test of the lock was performed in the shop on gasket seals, valves, shaft penetrations, nozzles and piping.

At the Monticello site, the reference system was tested by pressurizing with Freon and using a Halogen leak detector.

After installation, the dew cell elements and resistance bulbs were tested in position and found to be operating.

The reference system was purged of Freon and pressurized with nitrogen for the absolute pressure test. This test was started at 5:00 P.M. February 7, 1968, and concluded at 8:00 A.M., February 9, 1968

• F.A-4 REV 4 12/85

MONTICELLO The data compiled during this time, showed the reference system to be leak tight within the accuracy of the instruments. However, at the start of the leak rate test and after the final soap film test, a leak was found to have been created at Valve B. This leak was corrected and retested prior to starting the leak rate test. A discussion was held with General Electric, and it was agreed that another hold test of the reference system was not necessary.

A 2 psig soap film leak test of the inner door and a 10 psig soap film test of the exterior door of the.

personnel lock was made. No detectable leaks were found in either case.

The air space between the double gasketed connection of the head flange, equipment hatch, stabilizer hatches and manholes was pressurized to approximately 100 psig and soap film tested. No detectable leaks were found.

OVERLOAD TEST After testing of the reference system, the containment vessel was closed for the overload test. The suppression chamber had been filled with water in accordance with Step B-6 of the test instructions and at 12:00 noon on February 9, 1968, pressurizing operations were begun.

The vessel was pumped to 5 psig and a complete soap film test of the vessel was made.

Pressurizing operations were resumed and at 10:47 A.M.

February 10, 1968, overload pressure (70 psig) was reached. After one hour the pressure in the vessel was reduced to design pressure (56 psig) and the soap film test was started.

MONTICELLO LEAKAGE RATE TEST'*

The leakage rate test of the vessel in the wet condition began at Midnight, February 10, 1~-~. and terminated at 7:00 A.M., February 13, 1968. Internal fans were used in the dry\o:ell and suppression chamber for the circulation of air in order to obtain uniform conditions. External heaters were turned on intermittentl y to maintain a reasonable outside temperature.

To obtain a dew point temperature (and a water vapor pressure) three dew cells were located in the suppression chamber and three in the drywell. Ten resistance bulbs were used for temperatures, three in the suppression chamber, one in the water, one in the vent line, and five in the drywell. These locations are illustrated in Figure B.

At 7:00 A.M., Februarv 13, 1968, the leak rate test was concluded and the vessel pressure was reduced to atmospheric *

• RESULTS OF INSPECTIONS AND TESTS PRELIMINAR! ;...._ 1CKS The field magnetic particle inspection of manholes and nozzles did not find any indication of cracks or defects.

The leak tests of the locks in the field at 2 psig and 10 psig were satisfactory and no leaks were found. No leaks were found in pressurizing between the two gaskets of bolted covers.

The pressure-temperature data for the holding test of the reference system is tabulated in Appendix F.A.A. The results seem somewhat erratic because the internal heaters were operated intermittently during this test. However, to insure tightness a second Halogen leak test was

• performed on the reference system just prior to overload test. This test proved satisfactory.

OVERLOAD TEST AND SOAP FILM INSPECTION The overload test chart is reproduced in Appendix F.A.C. The hourly pressure-ambient temperature data recorded during the pump-up of the containment is tabulated in Appendix F.A.D.

During the overioad test one temporary plug blew out of a l" coupling on a 10" instrument line. The plug was replaced and the test resumed without incident.

The soap fi"lm test of the containment at the design pressure found several minor leaks. Several leaks were found on the temporary caps on the control rod drive penetrations. The plugs were tightened and the leaks minimized. Small leaks were found at the connection of power leads passing through the drywell. The only correction was to cut the leads

• and the decision was made to leave them alone and start the leak rate. Leaks were detected in four lock penetrations F.A-10 REV 4 12/85

MONTICELLO and these were plugged with temporary caps welded on the inside of the drywell. These plugs leaked somewhat but not sufficiently to stop the test. Also several leaks were found in the stuffing box connections on the lock door operating mechanism. These were of minor nature and were repaired after the test.

LEAK RATE TEST The hourly data recorded during the February 11-13, 1968, wet leakage rate test is tabulated in Appendix F.A.E. The readings began at Midnight, February 10 and there was indication of large leaks. By 8:00 A.M. February 11, the test was halted in order to determine the location of leaks.

The leaks were found to be at al" diameter coupling and also the power leads for heaters inside the drywell. The power leads were cut and the opening was capped by Bechtel and the l" diameter plug was changed. At Midnight,*February 11, test data gain began to be collected for the leakage rate test. Readings taken at 8:00 A.M. the following morning indicated no large leakage.

The circulating fans operated continuously during the test which helped provide a uniformity in the air vapor space. The data during the periods of 2:00 A.M. to 7:00 A.M.

on February 12, and 13 proved to be the most stable, and this data is summarized below. The atmospheric temperatures are in °F, the containment vessel pressures are in lbs./sq. inch absolute, and the differential manometer readings are in inches of water.

MONTICELLO From the above average internal air temperature and dew point-temperature, the relative per cent humidity for February 12, calculates to be 68.03% and 87.qll, respectively for the drywell and suppression chamber, and 73.75% and 89.7% for February 13.

Considering that the drywell and vent lines have 68% of the total volume of the containment vessel, the average water vapor pressures are .179 psi for February 12, and .191 psi for February 13.
