Page 1-30, add the following to the end of Section 1.7.3: | |||
"Amendment 34 - Date of Issuance: October 10, 2008 Amendment 34 authorized the MURR to revise the requirements for the conduct of fueled experiments. This amendment allowed Technical Specification 3.6.o to be changed such that fueled experiments, with inventories of iodine-131 through -135 greater than 1.5 curies or strontium-90 greater than 5 millicuries, could be placed in irradiation containers that satisfy the requirements of Specification 3.6.i. | |||
Amendment 35 - Date of Issuance: February 9, 2012 Amendment 35 authorized the MURR to implement a flux-trap irradiations safety device to the reactor protective system. This amendment allowed an increase in irradiation capacity in the center test hole by removing the reactivity contribution of the sample holder while also allowing the use of the 6-barrel sample holder for movable samples. | |||
Amendment 36 - Date of Issuance: July 8, 2013 Amendment 36 changed Section 2.1, "Reactor Core Safety Limit," of the Technical Specifications. The Safety Limits were revised to correct an error caused by misinterpreting the definition of "diameter of heated surface" (Di) in the Bernath correlation as. "heated diameter" (Dh). Additionally, updated peaking factors were used based on modem analyses." | |||

"December 2006 - Replacement of the Two Primary Coolant System Heat Exchangers The two existing primary coolant system shell and tube-type heat exchangers (HX 503A and HX 503B) were replaced by heat exchangers of plate-type design. This replacement was necessitated by the degradation of the heat transfer capability of the heat exchangers since they were approaching the end of their design operational lifetime. | |||
December 2006 - Replacement of the Pool Coolant System Heat Exchanger The current plate-type pool coolant heat exchanger was replaced with the exact same model that was initially installed in 1995 (with 151 plates). Since installation in 1995, the pressure drop across the heat exchanger had steadily increased, which resulted in a decrease in total pool coolant system flow rate. An evaluation of the pool coolant heat exchanger was performed in February 2005 by the Engineering Firm Black & Veatch (B&V), Kansas City, Missouri. In the evaluation B&V states that due to the tight clearances between the plates, the heat exchanger will act like a filter and collect impurities in the water. Additionally, the maker of the heat exchanger (Graham Corporation) had previously inspected plates that had what appeared to be a thin layer of surface contaminants. Both of these are sufficient to cause an increase in the pressure drop across the heat exchanger. Installation of the new heat exchanger returned total pool coolant system flow rate to design values. Furthermore, replacement of certain sections of pool coolant system piping in order to reduce operational system head losses and therefore increase available system flow were also performed in conjunction with the replacement of pool coolant heat exchanger HX-52 1. | |||

June 2014 - Construction of the Shipping and Receiving Building A Shipping and Receiving Building (SaRB) was constructed on-site to enhance the security at MURR by creating a location external to the main facility where packages are received, opened and examined prior to being transported into the facility. | |||
January_ 2012 - Replacement of the Cooling Tower The old cooling tower, which was a wood-framed, induced-draft, cross-flow type, with three cells and two-speed fan assemblies per cell, was replaced with a stainless steel, induced-draft, cross-flow type, with three cells and two-speed fan assemblies per cell. The new tower is designed to cool 5,400 gallons (20,440 1) of water per minute to a temperature of 85 IF (29.4 | |||
'C) from an initial temperature of 115 IF (46.1 °C) at a maximum wet bulb temperature of 80 | |||

1. | : 1. None Attention: Beth Asbury UM Project Manager As part of the ongoing work at the MURR facility, B&V has reviewed available performance information on the existing Pool Heat Exchanger. The following table shows a comparison of the pressure drop data recorded December 19, 1995 to the data recorded January 19, 2004. | ||
ATTACHMENT | December 19, 1995 January 19, 2004 Measurement P-508A P-508B Two Pump P-508A P-508B Two Pump Pool Flow' 1,027 1,063 1,191 955 947 1,153 HX 521 Inlet' 36 37.5 55 39.5 39 51.5 HX 521 Outlet" 28 29 44 28 28 36 Difference' 8 8.5 11 11.5 11 15,5 Notes: 1) Average flow rates in gallons per minute | ||
: 2) Pressures in psig. | |||
It can not be determined from the data if the secondary pumps were running when the pool coolant readings were recorded in 1995. Therefore, the January 19, 2004 data selected for comparison are from the cases where no secondary coolant pumps running. The recorded pressure drops from 2004 are higher when secondary pumps are running. | |||
Since the measured flow rates are lower and the corresponding pressure drops across the heat exchanger are higher in 2004 than in 1995 it is apparent that pressure drop on the pool side has increased over time. | |||
B&V has contacted Gary Trumpfheller, Sales Manager, Graham Corporation to discuss heat exchanger performance. Due to the tight clearance between the plates, the heat exchanger will act like a filter and collect impurities in the water. Contaminants can enter the system through the open reactor pool or with test samples. In the past, Graham Corporation has inspected plates that have what appears to be a thin layer of contaminants on the surface. | |||
This thin layer has been enough to increase the pressure drop across the heat exchanger. | |||
Based upon the discussion with the Mr. Trumpfheller, B&V recommends that the pool heat exchanger be disassembled and the plates inspected. Any damaged plates should be replaced. This should return the heat exchanger to a like new condition. If MURR purchases and installs a replacement pool heat exchanger, this inspection may be performed as part of the reconfiguration of this heat exchanger for the primary coolant service. | |||
building a world of difference". | |||
ATTACHMENT 4 Page 2 University of Missouri - Columbia B&V Project 138814 Beth Asbury February 18, 2005 In addition. Mr. Trumpfheller stated that the plates are indeed extremely flexible. Therefore, as the pressure increases on one side of the plate, the flow area decreases on the other side of the plate, resulting in an increase in the pressure drop. This phenomenon has been demonstrated for the pool heat exchanger by the increase in pressure drop observed on the pool side when the secondary side is operated. Since the flow rate and corresponding pressure drop are by design greater on the pool side of the heat exchanger, some increase in pool water flow can be achieved by decreasing the pressure in the heat exchanger on the secondary side. | |||
From discussions with the MURR staff, secondary coolant valve S-223 is used to throttle flow in Room 114. Since this valve is downstream of the pool heat exchanger, throttling it increases the pressure on the secondary side of the pool heat exchange. Moving the valve to upstream of the heat exchanger will reduce the pressure on the secondary side of the pool heat exchanger. This may result in a slight decrease in the pressure drop across the heat exchanger. | |||
Please contact Bill Luelf at 913-458-7878 or myself at 913-458-4605 should you have any questions. | |||

ATTACHMENT 4 MURR Introduction reactor was able to operate at 10 MW with a single pool pump in operation. Since plate and frame heat exchangers have multiple parallel flow paths, decreasing the number of plates proportionally decreased the number of flow paths. Therefore, the pressure drop across the heat exchanger increased as a result of decreasing the number of plates (and decreasing flow area). This pressure drop increase caused the unit to require both pool pumps to be running in order to operate the reactor at 10 MW. | |||
Another operational issue identified during discussions with MURR was spurious SCRAMS of the reactor due to changes in differential pressure across the Pool Loop Heat Exchanger when the secondary cooling system pumps are started. This has been attributed to the heat exchanger plates being too flexible, and is to be considered in the design of Primary Coolant System Heat Exchangers. | |||
A related issue identified by MURR was that the existing piping arrangement results in a static pressure of approximately 0 psig at the pool pumps suction during pool loop testing. MURR expressed interest in modifications to the piping that would improve the net positive suction head (NPSH) available for these pumps. | |||
A final operational issue identified by MURR was the desire to maintain targeted Pool and Primary temperatures with the highest outside dew-point possible. Therefore when operating at 10 MW, MURR is interested in having primary heat exchangers that will maintain the Primary Coolant Tc at 120 F with a secondary that has maintained the Pool Coolant Tc at 100 F using the Pool Heat Exchanger with 151 plates, and S-1 and S-2 in the middle of their flow bands. | |||
The Primary Coolant Heat Exchangers are not required during a beryllium change outage. Therefore, the heat exchanger replacement is planned for the beryllium change outage scheduled for January 2006. This outage is expected to be 6 days but the heat exchanger replacement should be performed as quickly as possible. The Pool Coolant System is required during the beryllium outage. Therefore, a separate outage is required for the Pool Coolant System modifications. This outage is tentatively scheduled for the end of 2006. The outage should be as short as practical. | |||
Finally, a walkdown inspection of Room 114 and immediate vicinity revealed that access to Room 114 is limited by the opening in an existing fence gate. The clear opening of the gate is 5 feet 7 inches wide by 7 feet 0 inch high. Although the entire gate may be removed to allow better access to the | |||

Installation of 8" Strainer in Pool Piping During the December, 2006 Primary and Pool Heat Exchanger Replacement project, the Pool Heat Exchanger (HX-521) was found to have foreign materials including small solid objects and fibrous matter in the Pool side inlet plenum. The fibrous material was identified as nylon, possibly the remains of a segment of the nylon rope commonly used in the bulk pool to store and handle various objects. | |||
Due to the nature of the plate-type heat exchanger, the new HX-521 could again accumulate such materials over time, resulting in an eventual degradation of flow capacity. The current Pool Coolant System strainer, 597B, is installed downstream of HX-52 1, and so provides no protection to the heat exchanger against accumulation of foreign materials. | |||
To ensure the long-term performance of HX-52 1, an additional strainer will be installed in the Pool System piping upstream of HX-521. The strainer, 597D, will be a Mueller Wye Strainer, of cast stainless steel construction, 8" raised-face flanges, 150 psi class, with a 0.062" opening wire mesh tack-welded to the rigid basket insert. It will be installed in the overhead piping in the pump discharge header to the heat exchanger. Piping fabrication drawings were modified and approved for the following Black and Veatch prints: 138814-IPCS-M4502C, and 138814-1 PCS-M4502D. These new drawings (attached) supersede the previously approved drawings of the same designation. The MURR P&ID Print 156 (also attached) now reflects the installation of Strainer 597D, as well as the associated '/2" flush/drain, Valve 518Z. | |||
The additional head loss introduced by installing this 8" strainer with 0.062" opening mesh is predicted to be on the order of 1.0 - 1.5 psid over the full range of flows, and expected to be near 1.2 psid when operating at the current target flowrate of 1200 gpm. This additional loss is expected to be small, and a net gain is still expected following installation of the new Pool Coolant System piping. | |||

Cooling Tower Replacement Project In preparation for and during the cooling tower replacement project MURR Health Physics analyzed four separate putential radioactive waste streams prior to demolition. These were: | |||
: 1. Cooling tower sump sludge | |||
: 2. Cooling tower sump liner material | |||
: 3. Underground secondary suction header soil sample | |||
: 4. Underground secondary suction header tritium analysis from soil sample. | |||
Items 1-3 above were analyzed for gamma identification using the HP germanium counting system in lab 213 while item 4 was analyzed for H-3 due to leakage from the secondary system header using the Packard 2300 LSC system. In all cases radioactive materials evidence was negative, as there were no isotopezs identified above background levels. Should you require more or additional information, please do not hesitate to contact me. | |||

Construction Details Modification Record 14-01 documented the construction of the MURR Industrial Building (MIB) Eastward Expansion. | |||
This letter documents the construction methods and details. | |||
The expansion is not directly mentioned in the Hazards Summary Report. The MIB is a part of the Laboratory Building. The extent of inclusion in the Hazards Summary Report is to show the expansion on the building floor plan drawings. | |||
The grade level floor is poured concrete designed for a 125 lb./ft2 live load with additional steel and concrete framing to support four (4), 100,000 lb. hot cells positioned next to each other anywhere along the North-South direction. The steel and concrete structure rests on pilings driven to bedrock. The below grade floor is also poured concrete designed to handle a 125 lb./ft.2 live load, additionally, the floor can handle a 10,000 lb. load on a 6 ft. x 6 ft. base plate. | |||
The East outer wall of the building has a masonry shield wall in part of the building as shown on the attached print. This is in place to reduce possible dose to the public from the cask loading taking place in the cask loading side of the hot cells. This wall is concrete block with all voids filled with grout. | |||
This expansion will provide an additional 1440 ft2 and 1432 ft2 of net usable space on the grade, and the below grade levels respectively. | |||
The building is construction type II-B. This type of construction utilizes non-combustible materials that do not provide a burn rating. There is an external drain tile sump with visual alarm indication of sump high level. This building also has heating ventilation and air conditioning, domestic cold water, domestic hot water, vacuum, and compressed air. For more | |||

This Modification Record documents changes to the facility Evacuation System that are necessary in order to safely occupy the MURR Industrial Building Eastward Expansion (MIB East). This is part of an effort to ensure all systems relating to emergency response are extended to MIB East. The initiating document for installation/extension of those systems is Modification Record 14-01, Interfacing MURR Systems with the MIB/BOB Eastward Expansion. Modification Record 90-1, "Evacuation Horns" provided for additional evacuation horns and lights as part of a major reconfiguration of the system in 1990. | |||
The MURR Evacuation System serves to actuate the MURR Containment Isolation System, and to provide an audible and visible indication via horns and lights to evacuate the facility via the nearest exit. The system can be manually actuated from either the control room (Room 302) or the facility lobby (Room 210). There is no automatic means to actuate the Evacuation System. The existing Evacuation System horns and lights are powered from the Emergency Lighting Panel in the Laboratory building and the North Office Addition Emergency Lighting Panel in NOA. | |||
Previous Modification Record 90-1; Addendum 1 stated that horns and lights may be added to the Evacuation System with Reactor Manager's approval, and without a separate Modification Record. This allows for reconfiguring as needs change within the facility. This Modification Record is being used to document a larger addition to the system as a result of the construction of the new structure. | |||
To ensure a prompt and effective response from MURR staff to an emergency or abnormal condition, the MURR Evacuation System will be extended to MIB East. This will require the addition of three (3) evacuation horns (see attached drawing) | |||

The MURR license renewal application (LRA,) SAR was submitted August 31, 2006. Changes to the facility since that time have been summarized in the MURR Annual Reports, but detailed information, including any relevant safety analyses, updated SAR sections, or results of any reviews of those changes performed in accordancewith the requirements of 10 CFR 50.59, have not been provided NUREG-1537, Section 1.8, "Facility Modifications and History, "provides guidance that significant modifications to the facility should be provided in the LRA.
- a. Provide a list of the significant changes to the MURR facility since the submittal of the LRA in August 2006.
The following are all of the facility modifications that were implemented at MURR in accordance with administrative procedure AP-RO- 115, "Modification Records," since the license renewal application (LRA) was submitted. The modifications are listed by the year that they were completed. Additionally, proposed changes to the Safety Analysis Report (SAR) based on these modifications are also listed as well as whether the modification was performed under a License Amendment or 10 CFR 50.59. Furthermore, at the end of this section is revised wording to Sections 1.7.3 and 1.7.4 of the LRA SAR. These facility changes would be considered "significant modifications" as per NUREG-1537, Section 1.8, and Modification Records and 50.59 Screens which document implementation of these changes are included as attachments. Facility changes performed under a License Amendment are also documented under a Modification Record, such as License Amendment No. 35 which was implemented under Modification Records 75-16, Addendum 4; 06-03, Addendum 2; and 11-01 (Attachments 19, 20 and 21). License Amendment No. 34 did not require any changes to the LRA SAR but the most recent version of the relicensing Technical Specifications (January 27, 2014, ADAMS Accession No. ML14030AI32) does incorporate this change (TS 3.6.o). License Amendment No. 36 revised the Safety Limits. Section 2.1 of the most recent version of the relicensing Technical Specifications does incorporate this change. Sections 4.6.2 and 4.6.3 of the LRA SAR will be replaced by Attachment 11 (Appendix F) of the August 24, 2011 submittal in support of License Amendment No. 36. Page 4 of 40
FACILITY MODIFICATIONS - YEAR 2006:
- 1. Modification 94-04, Addendum 1; "Replacement of Pool Coolant System Heat Exchanger HX 521" a) This addendum to Modification Record 94-04, "The Replacement of the Pool Tube and Shell Heat Exchangers with a Plate Type," documents the replacement of the current plate-type pool coolant heat exchanger with the exact same model that was initially installed in 1995 (with 151 plates). Since installation in 1995, the pressure drop across the heat exchanger had steadily increased, which resulted in a decrease in total pool coolant system flow rate. An evaluation of the pool coolant heat exchanger was performed in February 2005 by the Engineering Firm Black & Veatch (B&V), Kansas City, Missouri. In the evaluation B&V states that due to the tight clearances between the plates, the heat exchanger will act like a filter and collect impurities in the water. Additionally, the maker of the heat exchanger (Graham Corporation) had previously inspected plates that had what appeared to be a thin layer of surface contaminants. Both of these factors are sufficient to cause an increase in the pressure drop across the heat exchanger. Installation of the new heat exchanger returned total pool coolant system flow rate to design values.
b) Modification performed under 10 CFR 50.59. c) No wording changes to the SAR are required.
- 2. Modification 05-08; "Replacement of Primary Coolant System Heat Exchangers HX 503A and HX 503B" a) This Modification Record was used as the initiating document in a coordinated set of addenda whose purpose was to replace the existing primary coolant system heat exchangers, modify and upgrade existing flow detectors and associated instrumentation, replace affected primary coolant system piping, and replace and re-plumb affected secondary coolant system piping. Each major system modification (i.e. - instrumentation, and primary and secondary coolant system hydraulics) was documented as a separate addendum to this Modification Record.
b) Modification performed under 10 CFR 50.59. c) No wording changes to the SAR are required.
- 3. Modification 05-08, Addendum 1; "Replacement of PrimaryCoolant System Heat Exchangers HX 503A and HX 503B - InstrumentationPortion" a) This addendum to Modification Record 05-08, "Replacement of Primary Coolant System Heat Exchangers HX 503A and HX 503B," documents the instrumentation changes that were necessary to support the replacement of the old shell and tube-type primary coolant heat exchangers with new plate-type heat exchangers.

Primary coolant system flow is recorded on a strip-chart, two-pen recorder mounted on the instrument panel. Differential pressure across orifice Page 6 of 40
plates (Flow Element 913A and 913B) located downstream of HX503A and HX503B is measured by FT 912A and FT 912E, respectively. The output signal (10 to 50 mA) generated by each flow transmitter is directed to a Square Root Converter which provides a linear output signal for the two-pen recorder and a Dual Alarm Unit. In addition to providing flow indication, the recorder will initiate a "Reactor Loop Lo Flow" annunciator alarm if primary coolant flow downstream of either heat exchanger decreases to 95% of the normal operating value. If primary coolant flow decreases to 90% of the normal value, a reactor scram and a "Reactor Loop Lo Flow Scram" annunciator alarm are initiated. The Dual Alarm Unit for FT 912A opens a contact (K30-2) in the process input string to E4A of the Reactor Safety System NCLUs, thereby interrupting power to the control blade electromagnets. The Dual Alarm Unit for FT 912E opens a contact (K38-2) in the process input string to E3B of the NCLUs. A primary coolant system low flow scram may also be initiated by a low differential pressure across the primary coolant heat exchangers. Differential pressure across HX503A and HX503B, which provides an indication of flow, is measured by DPS 928A and DPS 928B, respectively. The output signal (4 to 20 mA) produced by each differential pressure sensor is directed to an Alarm Unit. If primary coolant flow decreases to 90% of the normal operating value, a reactor scram is initiated. The Alarm Unit for DPS 928A opens a contact in the process input string to E3B of the Reactor Safety System NCLUs, thereby interrupting power to the control blade electromagnets. The Alarm Unit for DPS 928B opens a contact in the process input string to E4A of the NCLUs. The Alarm Units will also de-energize relays 2K24 and 2K26, which will cause the following actions to occur:
- 1. "Low Primary HX AP Scram" annunciator alarm is initiated; and
- 2. In-Pool Heat Exchanger Isolation Valves V546A and V546B open.
The output signals produced by DPS 928A and DPS 928B also power meters on the instrument panel, thus providing the reactor operator with an indication of primary coolant heat exchanger differential pressure." Replace with: "Primary coolant system flow is measured at the following locations with the indicated Flow Transmitters (FTs) and Differential Pressure Sensors (DPSs); (a) Downstream of Primary Coolant Heat Exchanger (HX503A) - FT 912A and FT 912E; (b) Downstream of Primary Coolant Heat Exchanger (HX503B) - FT 912G and FT 912H; and (c) Differential Pressure across the Reactor Core - DPS 929. Page 7 of 40
Primary coolant system flow measurement system includes two orifice plates, one in each of the two heat exchanger legs. Flow as measured by two transmitters connected to each orifice plate is recorded on two, two-pen recorders mounted on the instrument panel. Differential pressure across orifice plates (Flow Element 913A and 913B) located downstream of HX503A and HX503B is measured by FT 912A and FT 912E, and FT 912G and FT 912H, respectively. The output signal (10 to 50 mA) generated by each flow transmitter is directed to a Square Root Converter which provides a linear output signal for the corresponding two-pen recorder and a Dual Alarm Unit. In addition to providing flow indication, the recorder will initiate a "Reactor Loop Lo Flow" annunciator alarm if primary coolant flow downstream of either heat exchanger decreases to 95% of the normal operating value. If primary coolant flow decreases to 90% of the normal value, a reactor scram and a corresponding "Reactor Loop A Lo Flow Scram" or "Reactor Loop B Lo Flow Scram" annunciator alarm is initiated. The Dual Alarm Unit for FT 912A opens a contact (K30-2) in the process input string to E4A of the Reactor Safety System NCLUs, thereby interrupting power to the control blade electromagnets. The Dual Alarm Unit for FT 912E opens a contact (K38-2) in the process input string to E3B of the NCLUs. The Dual Alarm Unit for FT 912G opens a contact in the process input string to E3B of the Reactor Safety System NCLUs, thereby interrupting power to the control blade electromagnets. The Alarm Unit for FT 912H opens a contact in the process input string to E4A of the NCLUs. Alarm Unit EP No. 920 A/B and EP No. 920 G/H will also de-energize relays 2K24 and 2K26 respectively, which will cause the following actions to occur:
- 1. Corresponding "Reactor Loop A Lo Flow Scram" or "Reactor Loop B Lo Flow Scram" annunciator alarm is initiated; and
- 2. In-Pool Heat Exchanger Isolation Valves V546A and V546B open."

The tubes, and all materials in contact with the primary coolant, are made of stainless steel. The primary coolant flow makes two passes through the tube side of the heat exchanger with a velocity of no greater than 7 ft/sec (2.1 m/sec). At a maximum of 1,600 gpm (6,057 lpm) of secondary water flow and an inlet water temperature at 87 OF (31 0C), one heat exchanger is capable of removing 17 x 106 BTU/h of heat from 1,800 gpm (6,814 1pm) of primary coolant water and returning it at 140 OF (60 'C)." Replace with: "The primary coolant heat exchangers are plate-type with all surfaces in contact with the reactor coolant constructed of stainless steel. At a maximum of 1,600 gpm (6,057 1pm) of secondary coolant flow at 87 OF (31 'C), one heat exchanger is capable of removing 16.9 x 106 BTU/hr of heat from 1800 gpm (6,814 1pm) of coolant and returning it at approximately 140 °F (60 'C)." Page 5-9, Section 5.4.3, Heat Exchangers: Delete: "The secondary water flow makes a single pass on the shell side of the primary coolant system heat exchangers and on the opposite plate side of the pool coolant in the pool coolant system heat exchanger." Replace with: "The secondary coolant flows on the opposite plate side of both the primary coolant system heat exchangers and the pool coolant system heat exchanger. In both the primary and pool coolant heat exchangers, the secondary coolant water flows in a cross-flow configurations to the process water being cooled."
- 5. Modification 05-10; "Replace Pressure Vessel Tie-Rod Clevis Pins with Instrumented Load-Cell Clevis Pins" a) This Modification Record documents the replacement of the reactor pressure vessel tie-rod clevis pins with instrumented load-cell clevis pins. The clevis pins are constructed with an internal strain gauge, as well as the full bridge circuit necessary to correlate strain to tension; thus, allowing a more accurate method of determining the load applied to the tie-rods.

The nuclepore facility was installed in 1977 to provide a means of producing finely controlled porosity in an irradiated plastic film. To accommodate the required equipment a redesigned thermal column door was installed. Within this door, a removable set of uranium-bearing 'fission plates' was exposed to thermal neutron flux in the thermal column facility. As the target film slid across these fission plates, the fission products released penetrated the film, thus producing finely distributed perforations, which were later acid-etched to produce the desired porosity. After the nuclepore facility was decommissioned and abandoned in place in 1993, Modification Record 96-01 documented the removal of gas lines, isolation valves and valve controls. The irradiator case (that part of the experiment that was moved into and out of the neutron flux) was removed using reactor test procedure RTP- 166D.

In addition to the above mentioned changes to the SAR, the following changes are also required: Page 1-30, add the following to the end of Section 1.7.3:
"Amendment 34 - Date of Issuance: October 10, 2008 Amendment 34 authorized the MURR to revise the requirements for the conduct of fueled experiments. This amendment allowed Technical Specification 3.6.o to be changed such that fueled experiments, with inventories of iodine-131 through -135 greater than 1.5 curies or strontium-90 greater than 5 millicuries, could be placed in irradiation containers that satisfy the requirements of Specification 3.6.i.
Amendment 35 - Date of Issuance: February 9, 2012 Amendment 35 authorized the MURR to implement a flux-trap irradiations safety device to the reactor protective system. This amendment allowed an increase in irradiation capacity in the center test hole by removing the reactivity contribution of the sample holder while also allowing the use of the 6-barrel sample holder for movable samples. Amendment 36 - Date of Issuance: July 8, 2013 Amendment 36 changed Section 2.1, "Reactor Core Safety Limit," of the Technical Specifications. The Safety Limits were revised to correct an error caused by misinterpreting the definition of "diameter of heated surface" (Di) in the Bernath correlation as. "heated diameter" (Dh). Additionally, updated peaking factors were used based on modem analyses." Page 1-33, add the following to the end of Section 1.7.4:
"December 2006 - Replacement of the Two Primary Coolant System Heat Exchangers The two existing primary coolant system shell and tube-type heat exchangers (HX 503A and HX 503B) were replaced by heat exchangers of plate-type design. This replacement was necessitated by the degradation of the heat transfer capability of the heat exchangers since they were approaching the end of their design operational lifetime.
December 2006 - Replacement of the Pool Coolant System Heat Exchanger The current plate-type pool coolant heat exchanger was replaced with the exact same model that was initially installed in 1995 (with 151 plates). Since installation in 1995, the pressure drop across the heat exchanger had steadily increased, which resulted in a decrease in total pool coolant system flow rate. An evaluation of the pool coolant heat exchanger was performed in February 2005 by the Engineering Firm Black & Veatch (B&V), Kansas City, Missouri. In the evaluation B&V states that due to the tight clearances between the plates, the heat exchanger will act like a filter and collect impurities in the water. Additionally, the maker of the heat exchanger (Graham Corporation) had previously inspected plates that had what appeared to be a thin layer of surface contaminants. Both of these are sufficient to cause an increase in the pressure drop across the heat exchanger. Installation of the new heat exchanger returned total pool coolant system flow rate to design values. Furthermore, replacement of certain sections of pool coolant system piping in order to reduce operational system head losses and therefore increase available system flow were also performed in conjunction with the replacement of pool coolant heat exchanger HX-52 1.

June 2014 - Construction of the Shipping and Receiving Building A Shipping and Receiving Building (SaRB) was constructed on-site to enhance the security at MURR by creating a location external to the main facility where packages are received, opened and examined prior to being transported into the facility. January_ 2012 - Replacement of the Cooling Tower The old cooling tower, which was a wood-framed, induced-draft, cross-flow type, with three cells and two-speed fan assemblies per cell, was replaced with a stainless steel, induced-draft, cross-flow type, with three cells and two-speed fan assemblies per cell. The new tower is designed to cool 5,400 gallons (20,440 1) of water per minute to a temperature of 85 IF (29.4
'C) from an initial temperature of 115 IF (46.1 °C) at a maximum wet bulb temperature of 80 °F (26.7 °C).
June 2014 - Construction of the MURR Industrial Building Eastward Expansion An eastward expansion to the MURR Industrial Building (MIB) was constructed in order to provide additional laboratory space at MURR - 1,440 ft2 and 1,432 ft2 of net usable space on the grade and the below grade levels, respectively. The grade level floor is poured concrete designed for a 125 lb/ft2 live load with additional steel and concrete framing to support four (4) 100,000 lb hot cells positioned next to each other anywhere along the North-South direction. The steel and concrete structure rests on pilings driven to bedrock. The below grade floor is also poured concrete designed to handle a 125 lb/ft2 live load. Additionally, the floor can handle a 10,000 lb load on a 6 ft x 6 ft base plate."

Project RL-76; "Production of 1-131 Radiochemical Sodium Iodide Solution," and 50.59 Screen No. 12-07; "Iodine-131 Processing Laboratory," are Attachments 22 and 23,' respectively. Changes to the SAR in support of the iodine facility are described in Section a. above under the Modification Records.
- 2. The proposed MURR Technical Specifications (TS) (see letter dated January 27, 2014, ADAMS Accession No. ML14030A132), TS 5.2, "Reactor Coolant Systems, Exceptions" Specifications a and b, do not have supporting information in the SAR necessary to justify the TS Bases for each.
Provide support information to explain the basis for TS 5.2, Exception a and b, or justify why no change is necessary. The bases for Technical Specification 5.2, Exceptions a and b, are implied in the bases for Specifications 5.2.a and 5.2.e. The basis for 5.2.a states: "Specification 5.2.a as excepted, permits reactor operation at 50% of full power in the event of a major component failure in which repairs cannot be accomplished in a reasonable period of time. The reactor was designed and has extensive safe operating history for operation at 50% of 10 MW cooling capacity. In this event, the shutdown system shall be secured in a manner such as to assure system integrity." The word "excepted" in the basis allows, for instance, a component, such as the primary coolant heat exchanger in the shutdown system (one of two parallel legs) to be removed for repairs while still allowing 5 MW operation with the operating system while not being in violation of Specification 5.2.a. Specification 5.2.c allows for Mode II operation with just one system, or leg. The basis for 5.2.a states: "Specification 5.2.e assures strength and corrosion resistance of the coolant system components and excepts some components in the instrumentation of the system which are not commercially available in the materials specified. The size of these components is such that a failure would not result in a hazard to safe operation of the reactor." The word "excepted" in the basis allows "...some components in the instrumentation of the system which are not commercially available in the materials specified. The size of these components is such that a failure would not result in a hazard to safe operation of the reactor." This exception allows for materials other than those stated in Specification 5.2.e.

ATTACHMENT 1 ORIGINAL AP-RO-1 15 Revision 2 I Modification Number: 05-8 MODIFICATION DESCRIPTION Provide a concise description of the system change. Include any proposed PRE-OPERATIONAL TESTS required for this change. (If additional pages are necessary, insert after this page.) The primary coolant system consists of the reactor pressure vessels, two main circulating pumps, two heat exchangers, two automatic isolation valves, a pressurizer, a closed in-pool convective cooling system (decay heat removal system), an in-pool invert loop and anti-siphon system, a fuel element failure monitoring system, a bypass loop for water clean-up, and associated piping and valves. Instrumentation is installed to monitor the system's operation, pressures, water temperatures, and flows. The primary coolant heat exchangers, designated as HX503A and HX503B, are tube-type, water-to-water shell, with removable tube bundles. The primary coolant flow makes two passes through the tube side of the heat exchanger with a velocity of no greater than 7 ft/sec. At a maximum of 1,600 gpm of secondary water flow and an inlet water temperature at 87 OF (31 OC), one heat exchanger is capable of removing 17E6 BTU/hr of heat from 1,800 gpm of primary coolant and returning it at 140 OF (60 OC). Two heat exchangers are installed for design power operation. This Modification Record will be used as the initiating document in a coordinated set of Addendums whose purpose is to replace the existing primary coolant heat exchangers, modify and upgrade existing flow detectors and associated instrumentation, replace affected primary coolant system piping, and replace and replumb affected secondary coolant system piping. Each major system modification (i.e. - Instrumentation, primary and secondary coolant system hydraulics) will be documented as a separate Addendum to this Modification Record. Each Addendum will include all of the information that a Long Form Modification Record contains: Modification Description, Hazards Summary Report Evaluation (including 50.59 Screening or Evaluation, if applicable), Reactor Safety Evaluation, Spare Parts Requirements, and any Operating or Compliance Procedure, Print, and/or PM revision required. Additionally, a formal crew evaluation, and subsequent review and approval by the Reactor Manager will be performed for each Addendum. The following two Addendums are proposed as the initial scope of work for this Modification Record. Modification Record 05-8, Addendum 1 will detail the instrumentation changes required to implement replacement of the primary coolant heat exchangers. This addendum primarily documents the changes associated with relocating two existing reactor safety system flow measurement instruments to new detectors, and associated changes to the control room Instrument Cabinet. Modification Description continued on Page 2a. 2 Attachment 8.2
ATTACHMENT 1 ORIGINAL AP-RO- 115 Revision 2 Modification Number: 05-8 MODIFICATION DESCRIPTION (con't) Addendum 2 will detail the primary coolant system changes required to implement replacement of the primary coolant heat exchangers. This Addendum primarily documents the following five modifications: (1) the choice of the replacement heat exchangers; (2) the geometry of the primary coolant piping required to backfit the replacement heat exchangers; (3) replacement of the existing flow orifice flanges to provide additional independent flow detection output; (4) the geometry of the secondary coolant piping required to backfit the replacement heat exchangers; and (5) installation of additional secondary coolant piping and valves required to provide backflush capability for the new heat exchangers. The addendums described above are planned to be implemented during one week-long outage in December of 2006. Additional work coinciding with that outage includes: Replacement of the Pool Coolant System Heat Exchanger (Modification Record 94-4; Addendum I); Replacement of Pool Coolant System Piping (Modification Record 05-6); Updating the "White Rat" Overlays (Modification Record 75-16; Addendum 3); and Replacement of Graphite Reflector Elements 6, 7 and 8. 2a Attachment 8.1

Aýtd 2 AP-RO-115 Revision 2 Modification Number: 05-8, Addendum 1 MODIFICATION DESCRIPTION Provide a concise description of the system change. Include any proposed PRE-OPERATIONAL TESTS required for this change. (If additional pages are necessary, insert after this page.) Primary coolant system flow rate is currently measured at the following locations with the stated Flow Transmitters (FT) and Differential Pressure Sensors (DPS): (a) Downstream of Primary Coolant Heat Exchanger HX 503A - FT-912A; (b) Downstream of Primary Coolant Heat Exchanger HX 503B - FT-912E; (c) Differential pressure across Primary Coolant Heat Exchanger HX 503A - DPS-928A; (d) Differential pressure across Primary Coolant Heat Exchanger HX 503B - DPS-928B; and (e) Differential pressure across the reactor core - DPS-929. Primary coolant flow rate is recorded on a strip-chart, two-pen recorder mounted on the control room Instrument Panel. Differential pressure across orifice plates (FE-913A and FE-9138) located downstream of HX 503A and HX 503B is measured by FT-912A and FT-912E, respectively. The output signal generated by each flow transmitter is directed to a square root converter which provides a linear output signal to the recorder and a dual alarm unit. In addition to providing flow indication, the recorder will initiate a "Reactor Loop Lo Flow" annunciator alarm if primary coolant flow downstream of either heat exchanger decreases to 95% of the normal operating value. If primary coolant flow decreases to 90% of the normal value, a reactor scram and a "Reactor Loop Lo Flow Scram" annunciator alarm are initiated. The dual alarm unit for FT-912A opens a contact (K30-2) in the process input string to E4A of the reactor safety system non-coincidence logic units (NCLU), thereby interrupting power to the control blade electromagnets. The dual alarm unit for FT-912E opens a contact (K38-2) in the process input string to E3B of the NCLUs. A primary coolant low flow scram may also be initiated by a low differential pressure across the primary coolant heat exchangers. Differential pressure across HX 503A and HX 5038, which provides an indication of flow, is measured by DPS-928A and DPS-928B, respectively. The output signal produced by each differential pressure sensor is directed to an alarm unit. If primary coolant flow decreases to 90% of the normal operating value, a reactor scram is initiated. The alarm unit for DPS-928A opens a contact in the process input string to E3B of the safety system NCLUs, thereby interrupting power to the control blade electromagnets. The alarm unit for DPS-928B opens a contact in the process input string to E4A of the NCLUs. The alarm units will also de-energize relays 2K24 and 2K26, which will cause the following actions to occur:
- 1. "Low Primary HX Delta-P Scram" annunciator alarm is initiated; and
- 2. In-Pool Heat Exchanger Isolation Valves V546A and V546B open.
As discussed in Modification Record 05-8, this addendum documents the instrumentation changes that are necessary to support the replacement of the current shell and tube-type primary coolant heat exchangers with new plate-type heat exchangers. Addendum 2 documents changes to the hydraulics of the primary and secondary coolant systems, namely the new heat exchangers and associated piping changes. Modification Description continued on Page 2a. 2 Attachment 8.2 0 RIGINAL
,IIGJWE2AP-ROIl15 Revision 2 Modification Number: 05-8. Addendum I MODIFICATION DESCRIPTION (con't)
The following instrumentation changes will be performed in support of replacing the primary coolant heat exchangers: I. Removal of differential pressure sensors DPS-928A and DPS-928B, and their associated alarm units and electronic meters.
- 2. Installation of new flow transmitters FT-912G and FT-912H, and their associated Square Root Converters, Alarm Units, and Flow Recorder. These new flow transmitters will perform all of the safety functions, including the opening of In-Pool Heat Exchanger Isolation Valves V546A and V546B, which DPS-928A and DPS-928B provided.
- 3. Relocation of the Meter Relay Units for TE-980A and TE-980B to the vacated areas from which the electronic meters for DPS-928A and DPS-928B were removed.
- 4. Relocation of the Primary and Pool Coolant Demineralizer Flow Recorder to the vacated area from which the Meter Relay Units for TE-98OAand TE-980B were removed.
- 5. Installation of a new Primary Coolant Flow Recorder, which will support new flow transmitters FT-912G and FT-912H, in the location from which the Demineralizer Flow Recorder was removed.
Replacement of the heat exchangers affords the opportunity to replace the current single set of sensor taps on the flanges for flow elements (orifices) FE-913A and FE-9131B. The new flanges will have two sets of taps, thus allowing two flow transmitters to be connected to a single flow orifice. This type of arrangement was first used at MURR when the pool coolant system heat exchangers were replaced in 1995. Although the MURR Technical Specifications allow the use of either a flow orifice or heat exchanger differential pressure to determine flow (TS 3.3.a, Note 1), the use of a calibrated flow orifice is much more desirable than using differential pressure across a heat exchanger. Installation of the new flanges will allow DPS-928A and DPS-928B, and all of their associated instrumentation, to be removed. The safety analysis to support the use of two flow transmitters on a single flow orifice, specifically conformance with IEEE-279, is discussed in detail in the Reactor Safety Evaluation section of this Modification Record. As shown on the Simplified Primarj,Flow InstrumentationBlock Diagram found in Attachment 5, flow transmitter FT-912E, which is currently connected to FE-913B (Primary 'B' Loop), will be connected to the second set of sensor taps on flow element FE-913A (Primary 'A' Loop). Two new flow transmitters, FT-912G and FT-912H, will be installed and connected to FE-913B (Primary 'B' Loop). Two new square root converters (designated EP No. 919G and EP No. 919H), two new dual alarm units (designated EP No. 920E/F and EP No. 920G/H), and a new flow recorder (designated EP No. 915G/H) will be installed and connected to the flow transmitters. Dual alarm unit EP No. 920A/B ("Yellow Leg") will actuate relay 2K26, which cause the In-Pool Heat Exchanger Isolation Valves V546A and V546B to open on a primary coolant low flow reactor scram, while dual alarm unit EP No. 920G/H ("Green Leg") will actuate relay 2K24 which will cause the same valves to open on the same type of scram. Modification Description continued on Page 2b. 2a NRIGINAL Attachment 8.1
ATTýM"[2 AP-RO- 115 Revision 2 Modification Number: 05-8, Addendum 1 MODIFICATION DESCRIPTION (con't) The new flow transmitters will be of the same style that are currently installed; Rosemount Model 1 151 Differential Pressure Transmitter (0 to 750 inches of water). Rosemount Model 1151 's have been used at MURR since 1976 with no abnormal or significant failures. The new square root converters will be Moore Industries Square Root Transmitters, the same model that replaced the old General Electric Measurement and Control (GE/MAC) square root converters for the primary, pool and demineralizer flow transmitters under Addendums 4, 6 and 7 to Modification Record 01-4. The new dual alarm units will be Absolute Process Instruments, Inc. Model I0OOG, the same model that was installed for the primary and pool flow transmitters under Addendums 10 and 12 to Modification Record 01-4. The new flow recorder will be the same model that is currently installed to display and record primary coolant flow; a Honeywell Model DPR IOOC installed under Modification Record 99-I. Design specifications and any additional technical information regarding the instrumentation that will be added to the reactor systems by this proposed change are contained in the previously mentioned Modification Records and are not duplicated here. Additionally, all models are currently installed at MURR and have some degree of operational history with no abnormal or significant failures. Relocation of the meters and recorders to their new locations will ensure that all related process parameters are displayed in a logical order on the control room Instrument Panel.

Yes: No: v/ Signature:. ,a-,---..Date: /s--( If YES, the change must be performed sý g a Long Form Modification Record. If NO, outline the basis for the decision. This modification does not involve a change to the Technical Specifications or a question pursuant to 10 CFR 50.59. A 50.59 Screen (06-33) is attached which shows that the proposed activity may be implemented without further evaluation or license amendment. Technical Specification 3.3.a states that four (4) instrument channels are required to provide a primary coolant low flow scram in Mode 1(10 MW) operation and two (2) are required for Mode 11 (5 MW) operation. Note (1) of this Specification states: "Flow orifice or heat exchanger delta-P (psi) in each operating heat exchanger leg corresponding to the flow value in the table." The proposed modification will still satisfy the requirements of Technical Specification 3.3.a. Primary coolant loss of flow and coolant accidents are analyzed in Appendix D and E of Addendum 4 to the Hazards Summary Report, respectively. This modification does not change the assumptions or alter the results or conclusions of either accident. The proposed modification of connecting two flow transmitters to a single flow orifice must also be evaluated to ensure the single failure criteria of IEEE-279, "Criterion for Protection Systems for Nuclear Power Generating Stations," are still met. Reactor Safety Evaluation continued on Page 4a. 4 Attachment 8.2

ATTA~tiAP-RO-1 Revision115 2 Modification Number: 05-8. Addendum I REACTOR SAFETY EVALUATION (con't) Appendix A of Addendum 4 describes how the reactor protective system was redesigned for the 10 MW upgrade such that the system met all the applicable criteria of IEEE-279. This Appendix was reviewed in detail to ensure that the proposed instrumentation modification still meets all the applicable criteria of IEEE-279. The primary coolant low flow scram instrument channels satisfy the definition of Channel Independence in IEEE-279 and would continue to satisfy the single failure criteria of the same document. Furthermore, IEEE-279 states, regarding the derivation of system inputs, that "To the extent feasible and practical, protection system inputs shall be derived from signals that are direct measures of the desired variables." Use of a flow orifice instead of heat exchanger differential pressure to determine system flow rate more closely satisfies this criterion. Additionally, the following regulatory documents were also reviewed to ensure that the proposed modification did not involve a question pursuant to 50.59. The sensing lines for the two transmitters will be located on opposite sides of the flow orifice flange. Each flow transmitter will be connected to the primary coolant flow scram instrument channels as described in this Modification Record. The two flow transmitters will not share any common sensing lines. This is consistent with the guidance in NRC Regulatory Guide I. 151, Instrument Sensing Lines. The channel independence of the sensing lines connected to the single flow orifice meet the guidance in NRC Regulatory Guide 1.75, Physical Independence of Electrical Systems. This Regulatory Guide references and incorporates Draft IEEE Standard, "Criteria for Separation of Class IE Equipment and Circuits," dated July 20, 1973. Section 5.8.2 of this draft Standard, under the heading Sensor to Process Connections, states: "...redundant pressure taps located on opposite sides of a large pipe may be considered to be separated by the pipe, but the lines leaving the taps must be protected against damage from a credible common cause unless other redundant or diverse instrumentation is provided." In MURR's case, the sensing lines from each orifice plate to the flow transmitters will be brought out of opposite sides of the flange and routed so that a credible failure could not disable both sets of sensing lines on each flow orifice. The backup scrams from core differential pressure and the primary coolant isolation valves V507A and V507B provide additional redundancy. 4a Attachment 8.1

ATTACHMENT 3 ORIGINAL AP-RO- 15 Revision 2 Modification Number: 05-8, Addendum 2 MODIFICATION DESCRIPTION Provide a concise description of the system change. Include any proposed PRE-OPERATIONAL TESTS required for this change. (If additional pages are necessary, insert after this page.) This Addendum to Modification Record 05-8 will detail the primary and secondary coolant system changes required to implement replacement of primary coolant heat exchangers HX 503A and HX 503B as initially discussed in Modification Record 05-8. Addendum 1 documents the instrumentation changes desired and required by the heat exchanger replacement. This Addendum will primarily document the following five hydraulic modifications:
- a. The choice of the replacement heat exchangers;
- b. The geometry of the primary coolant piping required to backfit the replacement heat exchangers;
- c. Replacement of the existing flow orifice flanges to provide additional independent flow detection;
- d. The geometry of the secondary piping required to backfit the replacement heat exchangers; and
- e. Installation of additional secondary coolant piping and valves required to provide backflush capability for the replacement heat exchangers.
The current primary coolant heat exchangers are water-to-water shell and tube-type with removable tube bundles. The tubes, and all materials in contact with reactor coolant water, are of stainless steel. The reactor coolant flows on the tube side of the exchanger with a velocity not in excess of 7 ft/sec. One heat exchanger is capable of removing 17E6 Btu/hr from 1800 gpm of coolant water and returning it at 140 IF, using a maximum of 1600 gpm of secondary water flow with its inlet water temperature at 87 OF. Two such heat exchangers are installed for design power operation at 10 MW. Differential pressure across HX 503A and HX 503B, which provides an indication of flow, is currently measured by DPS-928A and DPS-928B, respectively. These differential pressure sensors provide a flow signal which can initiate a reactor scram, annunciate the "Low Primary HX Delta-P Scram," and open In-Pool Heat Exchanger Isolation Valves V546A and V546B. The secondary coolant system provides a flow of cooling water to transfer heat from the primary and pool coolant system by means of heat exchangers HX 503A, HX 503B, and HX 521, respectively. Secondary coolant is throttled automatically by automatic temperature control Valve S-1. This valve bypasses secondary coolant around HX 503A and HX 503B to maintain primary coolant return temperature as measured by temperature element TE-901A at its desired set point. The shell sides of HX 503A and HX 503B, which are in contact with the secondary coolant, are constructed of carbon steel. These shells have required multiple repairs due to leaks, and are approaching the end of their operational lifetime due to the degrading integrity of the carbon steel shells. It is proposed to replace these heat exchangers with two 50% capacity plate and frame-type heat exchangers. Modification Description continued on Page 2a. 2 Attachment 8.2 ORIGINAL
rfttwA~LT 3 AP-RO-I 15 Revision 2 Modification Number: 05-8, Addendum 2 MODIFICATION DESCRIPTION (con't) An evaluation (Attachment I) of the replacement of the primary coolant heat exchangers was performed in December, 2004 by the Engineering Firm Black & Veatch (B&V), Kansas City, Missouri. That report concluded that the existing shell and tube-type heat exchangers may be replaced by two plate and frame-type heat exchangers with equivalent cooling capacity and with minimal piping modifications. Additionally, modeling was performed to verify that the following three major operational objectives were accomplished by the proposed design change.
- 1. The existing Primary and Secondary Coolant Pumps are adequate to provide the required cooling flow for their respective systems (Attachment 1, pg I-I).
- 2. When operating at 10 MW, the primary coolant heat exchangers maintain primary coolant Tc at 120 'F with a secondary coolant system that is also maintaining pool coolant Tc at 100 *F using a heat exchanger with 151 plates, and temperature control valves S-I and S-2 in the middle of their flow bands (50%), and outside dew-point at the highest possible (Attachment i, pg 2-2).
- 3. Heat exchangers chosen such that flow rate versus pressure drop across the primary coolant side remains essentially unchanged from the existing configuration. This ensures that no deviation from the existing Safety Analysis and Accident Analyses occurs. The replacement heat exchangers will therefore function as a component replacement from the perspective of thernmo-hydraulic performance (Attachment 1, pg 3-4).
The Graham Corporation plate and frame-type heat exchangers recommended by B&V are GPE-60 Model heat exchangers with 1200 square feet of heat transfer surface area using 201 plates (Attachment 2). The replacement heat exchangers will occupy roughly the same locations in Mechanical Equipment Room 114 as the existing heat exchangers with the exception that they are physically far smaller. They will retain the existing designations of HX 503A and HX 503B. MURR has a 10 year operational performance history using plate and frame-type heat exchangers since installation of the existing pool coolant heat exchanger HX 521 in 1995 (See Modification Record 94-4). Due to the geometry of the replacement heat exchangers and their piping connections, it is necessary to replace certain sections of the primary coolant system piping. Detailed specifications for this piping geometry are provided by B&V and included as Attachment 3. Existing system design requirements were met or exceeded in material specification, fabrication, and integrity evaluation. Detailed documentation for material, fabrication and integrity of the replacement piping components is included as Attachment 5. Procurement and fabrication of the replacement piping components was accomplished by MURR. Installation of the piping components will be accomplished by an outside contractor. Replacement of the heat exchangers affords the opportunity to replace the current single set of sensor taps on the flanges for flow elements (orifices) FE-913A and FE-913B. The new flanges have two sets of taps, thus allowing two flow transmitters to be connected to single flow orifice. Sensing lines will have high point vent valves installed to facilitate system venting. Modification Description continued on Page 2b. 2a ORIGINAL Attachment 8.1
AP-RO- 115 Revision 2 Modification Number: 05-8, Addendum 2 MODIFICATION DESCRIPTION (con't) This results in the addition of the following eight 1/22-inch stainless steel ball valves (shown on revised MURR Print No. 156): 599AM, 599AN, 599AO, 599AP, 599AQ, 599AR, 599AS, and 599AT. The two new flow transmitters FT-912G and FT-912H will have test fitting isolation valves that were not present with DPS-928A and DPS-928B. This results in the addition of the following four 1/-inch stainless steel ball valves (also shown on revised MURR Print No. 156): 599AU, 599AV, 599AW, and 599AX. This type of arrangement is currently in use in measuring pool coolant system flow, and has been shown to provide superior flow measurement and input to the reactor safety system than the use of differential pressure across a heat exchanger. Installation of the new flanges will allow DPS-928A and DPS-928B to be removed. Detailed explanation and analysis of the instrumentation changes is available in Modification Record 05-8, Addendum 1. Again, due to the geometry of the replacement heat exchangers and their piping connections, it is necessary to replace certain sections of the secondary coolant system piping. Detailed specifications for this piping geometry are provided by B&V and included as Attachment 4. Existing system design requirements were met or exceeded in material specification, fabrication, and integrity evaluation. Procurement, fabrication and installation of the secondary coolant system piping components will be accomplished by an outside contractor. One notable exception to the replacement piping is the relocation of the existing piping arrangement for temperature control valve S-I to the North wall of Mechanical Equipment Room 114. Each heat exchanger will be equipped with a secondary side relief valve to provide overpressure protection when the heat exchanger is isolated. These two relief valves (S-70 and S-71) will be set to 125 psig, as are the other secondary coolant system relief valves Due to the tight plate-to-plate clearances in these heat exchangers, the secondary side acts as a strainer and collects impurities over time. To mitigate this strainer effect and maintain optimal operational flexibility, B&V has provided the piping and valves required to back-flush the replacement heat exchangers. Back-flushing will be accomplished as required using procedural steps specified in the attached draft revision to OP-RO-480, "Secondary Coolant System." The modifications described above are planned to be implemented during one week-long outage in December of 2006. Additional work coinciding with that outage includes: Replacement of the Pool Coolant System Heat Exchanger (Modification Record 94-4; Addendum I); Replacement of Pool System Piping (Modification Record 05-6); Revision of "White Rat" Overlays (Modification Record 75-16, Addendum3); and replacement of the north side graphite reflector elements (6, 7, and 8).

SUMMARY
REPORT EVALUATION (con't) The following sections and figures of the HSR and its addenda will be revised as follows: I. Original HSR:
- a. Section 5.2.3 will be revised as follows:
"The heat exchangers are plate-type with all surfaces in contact with reactor coolant water being constructed of stainless steel. One heat exchanger is capable of removing 16.9 x 106 BTU/hr of heat from 1800 gpm of coolant water and returning it at approximately 140 OF, using a maximum of 1600 gpm of secondary water flow at 87 OF.
Two such heat exchangers are installed for design power operation."
- b. Section 5.4.2 will be revised as follows:
"The secondary water flows on the opposite plate side of the primary coolant in the primary coolant heat exchangers and on the opposite plate side of the pool coolant in the pool coolant heat exchanger. In both the primary and pool coolant heat exchangers, the secondary water flows in a cross-flow configuration to the process water being cooled."

Yes: No: Signature: Date: /- --06" If YES, the change must be performed using a Long Form Modification Record. If NO, outline the basis for the decision. This modification does not involve a change to the Technical Specifications or a question pursuant to 10 CFR 50.59. A 50.59 Screen (06-34) is attached which shows that the proposed activity may be implemented without further evaluation or license amendment. Technical Specification 4.4.a. states: "The reactor coolant system shall consist of not less than a reactor pressure vessel, two primary system pumps, primary pressurizer, two primary heat exchangers, two pool system pumps, one 100% capacity or two 50% capacity pool system heat exchanger(s), and one pool system hold-up tank plus all associated piping and valves." Additionally, Technical Specification 4.4.e. states: "All coolant system major components in contact with pool or primary water shall be constructed principally of aluminum alloys or stainless steel." The proposed modification will still satisfy the requirements of these Specifications. Primary coolant loss of flow and loss of coolant accidents are discussed in HSR Addendum 4, Appendices D and E, respectively. By request and by design, the replacement heat exchangers duplicate the thermal-hydraulic performance of the existing heat exchangers and therefore do not change the initial assumptions nor the results or conclusions of those analyses.

The likelihood of the primary to secondary coolant system leak scenario is significantly reduced or even eliminated due to the construction of the plate-type heat exchanger. Plate-type heat exchangers use alternating plate channels separated by gasket material to retain both primary coolant and secondary water. In this design primary coolant leakage to the secondary coolant system is not likely unless one of the stainless steel plates is defective. Any primary coolant leakage would immediately be detected by the secondary coolant monitor. Primary coolant leakage to atmosphere is a more likely scenario than leakage to the secondary coolant system, in which case the leakage would be evident and directed to the radioactive liquid waste retention system. The gasketing material of the heat exchangers is EPDM (ethylene propylene diene monomer) and identical to the material used in the primary coolant isolation valves V507A and V507B which experience much higher gamma radiation levels. Additionally, the same material is used in the pool coolant heat exchanger, which has been in service since 1995 with no leakage occurring. The complete or partial failure of a gasket in a plate-type heat exchanger would be no worse than a complete or partial failure of an end plate gasket on a tube and shell-type heat exchanger. Both are isolatable from the rest of the system and any leakage would be contained in Mechanical Equipment Room 114 or directed to the radioactive liquid waste retention system. Any leakage from the new plate-type heat exchangers, or from the existing tube and shell-type for that matter, would be an operational issue and not a reactor safety concern. Safety analyses relating to the relocation of flow instruments and ensuring the single failure criteria of IEEE-279 are still met by connecting two flow transmitters to a single flow orifice are performed in 50.59 Screen No. 06-33, and are associated with Modification Record 05-8; Addendum I. 4a ORIGINAL Attachment 8.1

ATTACHMENT 4 ORIGINAL AP-RO-1 15 Revision 2 ] Modification Number: 94-4, Addendum 1 MODIFICATION DESCRIPTION Provide a concise description of the system change. Include any proposed PRE-OPERATIONAL TESTS required for this change. (If additional pages are necessary, insert after this page.) The pool coolant system consists of two main circulating pumps, a heat exchanger, an automatic isolation valve, a reflector plenum natural convection valve, a hold-up tank, a return diffuser, a bypass loop for water clean-up, and associated valves and piping. The pool coolant heat exchanger, designated as HX 521, is a water-to-water plate-type with all surfaces in contact with pool water constructed of stainless steel. This heat exchanger is designed to remove 3.6E6 BTU/h of heat from 1,200 gpm of pool coolant and return it at 99 OF (37 1C) with a secondary coolant flow rate and inlet temperature of 500 gpm and 87 °F (31 1C), respectively. In 1995, Modification Record 94-4 documented the replacement of the two original, tube and shell-type pool coolant heat exchangers with a single plate-type consisting of 151 plates. The new heat exchanger was sized to reject the pool coolant system portion (-10%) of the 30 MW heat load that would be generated in a potential future reactor upgrade. A short time after installation, 50 of the 151 plates were removed because thermal equilibrium with the primary coolant system could not be maintained even with automatic temperature control valve S-2 in the fully open position - essentially the heat exchanger was removing more heat from the pool coolant system than was desired. Since installation in 1995, the pressure drop across the heat exchanger has steadily increased, which has resulted in a decrease in total pool coolant system flow rate. An evaluation (Attachment 1) of the pool coolant heat exchanger was performed in February 2005 by the Engineering Firm Black &Veatch (B&V), Kansas City, Missouri. In the evaluation B&V states that due to the tight clearances between the plates, the heat exchanger will act like a filter and collect impurities in the water. Additionally, the maker of the heat exchanger (Graham Corporation) had previously inspected plates that had what appeared to be a thin layer of surface contaminants. Both of these are sufficient to cause an increase in the pressure drop across the heat exchanger. Modification Description continued on Page 2a. Why a Short Form is appropriate. (At least one of four reasons listed on Page 1, with justification) The short form of the Modification Record is appropriate because (a) this is an Addendum to an existing, previously reviewed and approved Modification Record (94-4), and (b) this is a modification to a non-safety system that requires documentation and review only. 2 Attachment 8. 1
ATTACHMENT 4 ORIGINAL AP-RO-I 15 Revision 2 Modification Number: 94-4: Addendum I MODIFICATION DESCRIPTION (con't) Based on these findings and the discussions with the Graham Corporation, B&V recommended the following two corrective options:
- 1. Disassembly and inspection of the heat exchanger, and any damaged plates replaced - this should return the heat exchanger to a like new condition, or
- 2. Installation of a new heat exchanger, which may be performed as part of the reconfiguration of the primary coolant system. Essentially, the new pool coolant heat exchanger would be designed to be thermally balanced with the new primary coolant heat exchangers.
Relevant pages (Attachment 2) from the evaluation report (Project No. 40003 1, Replacement of Primary Coolant System Evaluation Report) for system upgrades to the primary and pool coolant systems, mainly replacement of the system heat exchangers are attached. On page 2-2, an operational issue was identified by MURR in which it was desired to maintain primary and pool coolant temperatures at normal operating values with the highest outside dew-point. Basically, when operating at 10 MW, the primary coolant heat exchangers would maintain primary coolant Tc at 120 'F with a secondary coolant system that is also maintaining pool coolant Tc at 100 'F using a heat exchanger with 151 plates, and temperature control valves S-I and S-2 in the middle of their flow bands. By increasing the number of plates, which will decrease the pressure drop across the heat exchanger, coupled with piping improvements to the pool coolant system (See Modification Record 05-6), this should allow operation at 10 MW with only one pool coolant pump, if so desired. This was the case prior to the removal of the 50 plates from the current heat exchanger. Therefore, this addendum to Modification Record 94-4 documents the replacement of the current plate-type pool coolant heat exchanger with the exact same model (Attachment 3) that was initially installed in 1995 (with 151 plates). Installation of the new heat exchanger should return total pool coolant system flow rate to design values. Attachments: I.

This modification does not involve a change to the Technical Specifications or a question pursuant to 10 CFR 50.59. The proposed modification may be considered a maintenance activity as defined in the "Guidelines for 10 CFR 50.59 Implementation," NEI 96-07, Revision 1, November 2000, prepared by the Nuclear Energy Institute (NEI). Maintenance activities are activities that restore SSCs to their as-designed condition, including activities that implement approved design changes. These activities include troubleshooting, calibration, refurbishment, maintenance-related testing, identical replacements, housekeeping and similar activities that do not permanently alter the design, performance requirements, operation or control of SSCs. A 50.59 Screen (06-35) is attached which shows that the proposed activity may be implemented without further evaluation or license amendment. Additionally, as part of the safety analysis for Modification Record 94-4, the facility submitted a request to the U.S. Nuclear Regulatory Commission (NRC) to change the MURR Technical Specifications to support the replacement of the two original 50% capacity tube and shell-type pool coolant heat exchangers with one 100% capacity plate-type heat exchanger.

Pool Heat Exchanger Evaluation

- 1. None Attention: Beth Asbury UM Project Manager As part of the ongoing work at the MURR facility, B&V has reviewed available performance information on the existing Pool Heat Exchanger. The following table shows a comparison of the pressure drop data recorded December 19, 1995 to the data recorded January 19, 2004.
December 19, 1995 January 19, 2004 Measurement P-508A P-508B Two Pump P-508A P-508B Two Pump Pool Flow' 1,027 1,063 1,191 955 947 1,153 HX 521 Inlet' 36 37.5 55 39.5 39 51.5 HX 521 Outlet" 28 29 44 28 28 36 Difference' 8 8.5 11 11.5 11 15,5 Notes: 1) Average flow rates in gallons per minute
- 2) Pressures in psig.
It can not be determined from the data if the secondary pumps were running when the pool coolant readings were recorded in 1995. Therefore, the January 19, 2004 data selected for comparison are from the cases where no secondary coolant pumps running. The recorded pressure drops from 2004 are higher when secondary pumps are running. Since the measured flow rates are lower and the corresponding pressure drops across the heat exchanger are higher in 2004 than in 1995 it is apparent that pressure drop on the pool side has increased over time. B&V has contacted Gary Trumpfheller, Sales Manager, Graham Corporation to discuss heat exchanger performance. Due to the tight clearance between the plates, the heat exchanger will act like a filter and collect impurities in the water. Contaminants can enter the system through the open reactor pool or with test samples. In the past, Graham Corporation has inspected plates that have what appears to be a thin layer of contaminants on the surface. This thin layer has been enough to increase the pressure drop across the heat exchanger. Based upon the discussion with the Mr. Trumpfheller, B&V recommends that the pool heat exchanger be disassembled and the plates inspected. Any damaged plates should be replaced. This should return the heat exchanger to a like new condition. If MURR purchases and installs a replacement pool heat exchanger, this inspection may be performed as part of the reconfiguration of this heat exchanger for the primary coolant service. building a world of difference".
ATTACHMENT 4 Page 2 University of Missouri - Columbia B&V Project 138814 Beth Asbury February 18, 2005 In addition. Mr. Trumpfheller stated that the plates are indeed extremely flexible. Therefore, as the pressure increases on one side of the plate, the flow area decreases on the other side of the plate, resulting in an increase in the pressure drop. This phenomenon has been demonstrated for the pool heat exchanger by the increase in pressure drop observed on the pool side when the secondary side is operated. Since the flow rate and corresponding pressure drop are by design greater on the pool side of the heat exchanger, some increase in pool water flow can be achieved by decreasing the pressure in the heat exchanger on the secondary side. From discussions with the MURR staff, secondary coolant valve S-223 is used to throttle flow in Room 114. Since this valve is downstream of the pool heat exchanger, throttling it increases the pressure on the secondary side of the pool heat exchange. Moving the valve to upstream of the heat exchanger will reduce the pressure on the secondary side of the pool heat exchanger. This may result in a slight decrease in the pressure drop across the heat exchanger. Please contact Bill Luelf at 913-458-7878 or myself at 913-458-4605 should you have any questions. Very truly yours, BLACK & VEATCH Carl A. Rainey Project Manager

ATTACHMENT 4 MURR Introduction reactor was able to operate at 10 MW with a single pool pump in operation. Since plate and frame heat exchangers have multiple parallel flow paths, decreasing the number of plates proportionally decreased the number of flow paths. Therefore, the pressure drop across the heat exchanger increased as a result of decreasing the number of plates (and decreasing flow area). This pressure drop increase caused the unit to require both pool pumps to be running in order to operate the reactor at 10 MW. Another operational issue identified during discussions with MURR was spurious SCRAMS of the reactor due to changes in differential pressure across the Pool Loop Heat Exchanger when the secondary cooling system pumps are started. This has been attributed to the heat exchanger plates being too flexible, and is to be considered in the design of Primary Coolant System Heat Exchangers. A related issue identified by MURR was that the existing piping arrangement results in a static pressure of approximately 0 psig at the pool pumps suction during pool loop testing. MURR expressed interest in modifications to the piping that would improve the net positive suction head (NPSH) available for these pumps. A final operational issue identified by MURR was the desire to maintain targeted Pool and Primary temperatures with the highest outside dew-point possible. Therefore when operating at 10 MW, MURR is interested in having primary heat exchangers that will maintain the Primary Coolant Tc at 120 F with a secondary that has maintained the Pool Coolant Tc at 100 F using the Pool Heat Exchanger with 151 plates, and S-1 and S-2 in the middle of their flow bands. The Primary Coolant Heat Exchangers are not required during a beryllium change outage. Therefore, the heat exchanger replacement is planned for the beryllium change outage scheduled for January 2006. This outage is expected to be 6 days but the heat exchanger replacement should be performed as quickly as possible. The Pool Coolant System is required during the beryllium outage. Therefore, a separate outage is required for the Pool Coolant System modifications. This outage is tentatively scheduled for the end of 2006. The outage should be as short as practical. Finally, a walkdown inspection of Room 114 and immediate vicinity revealed that access to Room 114 is limited by the opening in an existing fence gate. The clear opening of the gate is 5 feet 7 inches wide by 7 feet 0 inch high. Although the entire gate may be removed to allow better access to the adjacent hallway, the existence of conduit and piping in the hallway makes the gate dimensions a practical limit [or any item brought to or removed from Room 114. As part of this walkdown, and subsequent discussions, it is clear that welding on current Primary and Pool piping in Room 114 should be minimized or eliminated to minimize the outage. 2-2 122004-1 122004-1 2-2
ATTACHMENT 4 MURR Analysis Moving the tank into place as a single unit will result in more of the existing piping being temporarily removed. To speed up final assembly, tank turning rolls would be used to keep the tank in an optimum position for welding. By continuously or semi-continuously rolling the tank, the welder will be able to constantly perform a horizontal weld, which is typically the easiest and fastest weld to make. The use of tank turning rolls when performing circumferential welded joints should allow the fabrication of a welded tank to be competitive with a bolted joint. Based on AWWA C207 72 inch diameter flanges, the bolted tank will have approximately 60 bolts per connection. Each nut and bolt or stud and bolt assembly could weigh between 5 and 10 pounds. Therefore, the bolting of each flange will take time and effort, especially with the bolts on the bottom and on the backside of the tank. Additional discussion will be provided in the Preliminary Cost and Schedule Report. 3.2.5 Demolition Considerations The demolition of the existing tank is expected to be on the critical path of the outage. Therefore, any reduction or elimination of work to be performed during the outage will have a direct impact on outage duration. Discussion with John O'Neil of Chase Environmental has revealed that the existing tank may be cut apart in about 36 hours. The tank would be cut into sections for removal from Room 114. The sections would be shipped offsite for decontamination and disposal. In addition to the time required to cut the tank apart, additional time in Room 114 will be necessary to set up and take down radiological controls and for removal of tank sections. Additional discussion will be provided in the Preliminary Cost and Schedule Report. 3.3 Pool Coolant System Pressure Drop Recovery In Deccmber 1995, 50 plates were removed from the Pool Coolant Heat Exchanger. Prior to the removal of the 50 plates. the reactor could be operated at 10 MW with only a single pool pump in service. After the removal of the plates, due to the increased differential pressure that resulted from the reduced flow area in the heat exchanger, a single pool pump was not sufficient to supply the coolant flow. 3.3.1 Heat ExchangerPressureDrop Evaluation Predicted differential pressure across the Pool Loop Heat Exchanger was requested from the original equipment manufacturer, Graham Corporation., for the cases 122004-1 3-10
ATTACHMENT 4 MURR Analysis of 950 gpm, 1,200 gpm, and 1,600 gpm for the current configuration of 101 plates. The submitted data sheets from Graham are included in Appendix A. The predicted data was compared to the measured data provided by MURR in support of this study (Appendix B) and the values are given in Table 3-5. The value given for the measured pressure drop is based upon the average values recorded for single pool pump operation with two secondary cooling pumps operating and are corrected to reflect the apparent calibration error of the pressure indicators. Table 3-5 Primary Side Pressure Drop for the Pool Loop Heat Exchanger Measured Number of Plates Predicted (2004) 151 Plates at 1,100 gpm 4.8 psi Unknown 101 Plates at 1,100 gpm 9.9 psi 20.0 psi It was discovered during the preparation of the preliminary isometric drawings that the piping was connected in reverse of that shown on Graham drawings. The actual primary side inlet piping was connected to what Graham shows as the secondary side outlet and the actual secondary side inlet piping was connected to the primary side inlet. MURR confirmed that on the final heat exchanger drawings submitted by Graham, this was an approved alternate configuration. MURR provided perfbrmance data for the 101 plate configuration dated December 19, 1995 (see Appendix B). The data sheet is annotated with a note reading: "HX differential press is" lower than what Graham predicted They said 11. 7psi and we have 11 psi." The value attributed to Graham (11.7 psi at 1200 gpm) is the same as the predicted performance from Graham for the 101 plate configuration at the same flow rate (see Appendix A). Therefore, reversing the direction of flow through the heat exchanger had limited impact on the pressure drop. Comparing the test data recorded in 1995 to that recorded in 2004 indicates that the measured pressure drop has increased. This may be due to fouling or foreign matter collecting in the heat exchanger and reducing the flow area. It is recommended that this be investigated further as part of Phase II design activities. It is assumed that with the reinstallation of 50 plates that any issues with fouling or foreign matter will be resolved and the heat exchanger will be restored to its original condition. This will allow the reactor to operate at full power on a single pool pump. However, if the degradation of heat exchanger performance as reflected in pressure drop was the result of fouling, or foreign matter collecting within the heat exchanger. then over 122004-1 3-11
ATTACHMENT 4 MURR Analysis time performance may again degrade to the point where two pool pumps are required to provide sufficient pool cooling flow. This may be alleviated in part by increasing the size of some of the pool system piping to offset the change in differential pressure across the heat exchanger. Performance data is not available to determine the actual pressure drop with the original installation of 151 plates. Since the reported pressure drop for 101 plates in 1995 was slightly less than the pressure drop predicted by the manufacturer, it is assumed that actual pressure drop with 151 plates was also slightly less than manufacturer predicted values. Therefore, the original as installed pressure drop for the 151 plate installation will be estimated to be 4.8 psi at a flow rate of 1100 gpm. Review of the available data for 101 plate configuration reveals that the pressure drop across the pool heat exchanger has increased by a little more than double over the last nine years (from 9.9 psi to 20 psi at a flow rate of 1100 gpm). The design criteria for modifying the piping is to increase size as necessary to reduce the friction loss in piping and mechanical devices by 5 psi at a flow rate of 1075 gpm. 3.3.2 System Analysis AFT Fathom software program was again used for the modeling. The basis for the Pool Coolant System piping model is as described for the Primary Reactor Coolant System piping in Subsection 3.1.3. The base scenario for each piping system analyzed reflects the piping as currently installed and operating. Test data provided by MURR (Appendix B) was used to estimate pressure drop for various components, create boundary and flow conditions, and to reconcile the model with actual system performance. Because the primary concern of the analysis is to identify piping and in-line devices to be replaced to reduce system pressure drop, modeling simplifications and techniques discussed in Subsection 3.1.3 were used. The calculated properties from AFT Fathom for the pumps for all cases discussed are given in Appendix C. Calculation files showing the spectrum of results are included on the enclosed CD-ROM. The results of the baseline analysis of the Primary Coolant System using AFT Fathom are generally consistent with the as-measured valves provided by MURR. It was previously noted that the data provided by MURR exhibits some scatter. For example, under the no pump case, the pressure indicators on the suction and discharge of the pool pumps range from 9 psig to 10.5 psig. These instruments are all measuring the same condition in this case (static head) and should indicate the same value. However. since this scatter does not affect conclusions of this study, further investigation is not required at this time. 122004-1 3-12

ATTACHMENT 5 ORIGINAL AP-RO-! 15 Revision I Modification Number: 05-6 MODIFICATION DESCRIPTION Provide a concise description of the system change. Include any proposed PRE-OPERATIONAL TESTS required for this change. (If additional pages are necessary, insert after this page.) Summary This Modification Record replaces certain existing Pool System piping with larger diameter piping. This modification will reduce operational head loss and therefore increase available system flow. A future change, Modification Record 94-4, Addendum 1, will replace the existing pool heat exchanger to better balance the heat transfer capacity of the Pool System and Secondary System, and help to minimize an existing dynamic effect of Secondary flow on Pool flow.
Background
The Pool Coolant System includes the following: The reflector plenum natural convection valve, an automatic isolation valve, a hold-up tank, main circulating pumps, a plate type heat exchanger, a pool return diffuser and associated piping and valves. The basic design conditions for the pool loop cooling system are that it will transfer 3.6 x 10A6 BTU/hr (roughly 1 MW) at a flow rate of 1200 gpm. It is desired to increase all four-inch pipe diameters to six-inch pipe diameters for the following reasons:
- 1. Current Pool System flow is typically less than 1100 gpm and due to various factors occasionally reduces to the chosen low flow alarm value of 1060 gpm.
- 2. The Hazards Summary Report states that pool loop coolant flow rates are adjustable to provide optimum cooling rates for various possible experimental arrangements in the reflector. This statement is only true in part, as no increase in flow is available through throttling.
- 3. While flow assumptions in the reflector are very conservative and no such limits are currently being approached, future experiment configurations may require additional cooling capacity.
(Modification Description continued on Page 2a) Why a Short Form is appropriate. (At least one of four reasons listed on Page 1, with justification) The short form of the Modification Record is appropriate because this is a modification to a non-safety system that requires documentation and review only (Reason No.4). 2 Attachment 8. 1
ATTACHMENT 5 ORIGINAL AP-RO- 115 Revision I Modification Number: 05-6 MODIFICATION DESCRIPTION (con't)
- 4. Current pump suction pressure is typically at or slightly below atmospheric pressure.
Increased pipe diameters at the pump suctions can help to increase the NPSH and reduce cavitation, resulting in longer pump service life and increased pumping efficiency.
- 5. Reduced head loss in the system may allow single-pump operation of the pool coolant system, providing greater maintenance and repair flexibility.
Scope of Work The modification will consist of fabrication, testing, and installation of various sections of Pool System piping, followed by verification of the overall system performance. Black and Veatch Engineering was contracted to analyze and design this piping configuration as part of a larger upgrade to the Pool and Primary systems. MU Project 400031 Mechanical Construction Specifications and Pool and Primary Coolant Piping Drawings contain detailed design data and analysis supporting the piping being fabricated and installed in this modification. Six-inch diameter aluminum piping will replace four-inch diameter aluminum piping, and where appropriate, six-inch isolation and check valves will replace four-inch isolation and check valves in the Mechanical Equipment Room 114. System function and flowpath will remain as existing, though specific pipe routing and pipe hanger locations will change to some degree. Other system components such as the automatic valve, hold-up tank, circulating pumps, heat exchanger and interfacing system connections will remain as existing and unchanged by this modification. The predicted increase in flow capacity will allow throttling of Pool System Valve 600A to control system flow rather than by physical limitations of the Pool System itself. Pool pump suction and discharge piping that is now four-inch diameter piping will be replaced with six-inch diameter piping. The pump isolation and check valves will be replaced with six-inch stainless steel gate-type isolation and swing-check valves. Inlet piping to the pump suctions will be fabricated with two-inch drain lines and equipped with diaphragm-type isolation valves. Existing pump bypass piping configurations will be eliminated. The current HX-521 Inlet Valves 522A and 522D are parallel four-inch paths, which will be replaced with a single six-inch path and a single stainless steel gate-type isolation valve. Connections to piping and pump flanges and valve flanges will be made consistent with respect to raised-face vs. flat-faced flanges. A pipe tee will be installed and blanked off at the common pump suction to facilitate a possible future emergency recirculation system. Specific Tasks - Fabricate piping sections per Black and Veatch (UM Project 400031) drawings M-4501A through M-4502H (see attached) - Perform and document all required non-destructive testing including radiography and hydrostatic pressure tests - Measure and record pool system performance prior to performing modifications - During a scheduled outage, replace piping sections per approved work sequence - Measure and record pool system performance following modifications - Control Pool System flow by throttling HX-521 Outlet Valve 600A This work is being performed under MU Project No. 40003 1, Replace Primary Cooling System. 2a Attachment 8.1

Date: "7-2_o-0(C If YES, make an analysis below and provide the suggestedrevision(s) to the HSR. If NO, outline the basis for the decision. This modification involves a change to the reactor facility as defined in the Hazards Summary Report (HSR) and its addenda. The following is a list of Sections and Figures in the HSR and its addenda where the Pool System is described or discussed: Original HSR
- 1. Figure 5.1 - MURR Print No. 156
- 2. Section 5.3 - Pool Loop Cooling System
- 3. Section 13 - Accident Analysis Addendum 3
- 1. Section 2.2 - Pool Coolant System Addendum 4
- 1. Figure A.2 - MURR Print No. 156 The following Sections and Figures are affected by this modification and will be revised as follows:
Hazards Summary Report
- 1. Figure 5.1 - MURR Print No. 156 Revise to reflect new piping size and configuration Addendum 4
- 1. Figure A.2 - MURR Print No. 156 Revise to reflect new piping size and configuration All other sections within the Hazards Summary Report (HSR) and its addenda will remain unchanged. The accident analysis in Chapter 13 deals with boiling within the flux trap and reflector regions, and analyzes a pool loop rupture scenario. Both analyses make no specific assumptions about the process side of the pool system, only the effects on the reactivity, cooling, and shielding of the core. The 10 MW upgrade description in Addendum 3 discusses specific valves that are affected by this modification, but will remain intact to preserve the detailed examination involved in doubling the cooling capacity of the Pool System at that time.
No change of that magnitude is being performed by this modification. 3 Attachment 8.1I

The operators performing the check will independently verify the position of each valve and indicate the verification by initialing the checksheet. Where appropriate, the positions of throttled valves are shown on a permanent tag secured to the valve. Note the throttled valve's position on the checksheet. Under the direction of the LSRO, a valve may be positioned other than listed on this checksheet. If this is required, the operators must ensure that the valve is in the desired position and indicate this position on this checksheet. If this change of position is not covered by a procedure in use, for example an RTP, SMP, or Work Package, which would return the valve to the normal operating position, then the LSRO will issue and place a Danger Tag on the valve for the duration of time the valve is in the out-of-normal position.

Subject:
Installation of 8" Strainer in Pool Piping During the December, 2006 Primary and Pool Heat Exchanger Replacement project, the Pool Heat Exchanger (HX-521) was found to have foreign materials including small solid objects and fibrous matter in the Pool side inlet plenum. The fibrous material was identified as nylon, possibly the remains of a segment of the nylon rope commonly used in the bulk pool to store and handle various objects. Due to the nature of the plate-type heat exchanger, the new HX-521 could again accumulate such materials over time, resulting in an eventual degradation of flow capacity. The current Pool Coolant System strainer, 597B, is installed downstream of HX-52 1, and so provides no protection to the heat exchanger against accumulation of foreign materials. To ensure the long-term performance of HX-52 1, an additional strainer will be installed in the Pool System piping upstream of HX-521. The strainer, 597D, will be a Mueller Wye Strainer, of cast stainless steel construction, 8" raised-face flanges, 150 psi class, with a 0.062" opening wire mesh tack-welded to the rigid basket insert. It will be installed in the overhead piping in the pump discharge header to the heat exchanger. Piping fabrication drawings were modified and approved for the following Black and Veatch prints: 138814-IPCS-M4502C, and 138814-1 PCS-M4502D. These new drawings (attached) supersede the previously approved drawings of the same designation. The MURR P&ID Print 156 (also attached) now reflects the installation of Strainer 597D, as well as the associated '/2" flush/drain, Valve 518Z. The additional head loss introduced by installing this 8" strainer with 0.062" opening mesh is predicted to be on the order of 1.0 - 1.5 psid over the full range of flows, and expected to be near 1.2 psid when operating at the current target flowrate of 1200 gpm. This additional loss is expected to be small, and a net gain is still expected following installation of the new Pool Coolant System piping. The existing Pool Coolant System strainer is not specifically described in the Original Hazards Summary. Addendum 3, while making specific mention of the existing strainer, is traditionally not revised in order to preserve knowledge of the 10 MW upgrade. Therefore, the only revision required to the Hazards Summary Report will be the revised MURR P&ID Print 156, reflecting the addition of the strainer.

QR04&NT 6 AP-RO-I 15 Revision 3 I Number: 09-1 Modification MODIFICATION DESCRIPTION Provide a concise description of the system change. Include any proposed PRE-OPERATIONAL TESTS required for this change. (If additional pages are necessary, insert after this page.) This Modification Record documents the addition of the new Shipping and Receiving Building to the MURR facility. Several systems within the MURR facility are in place to ensure a prompt and effective response from MURR staff to an emergency or abnormal condition. These systems will also be required to be in place in order to safely occupy the Shipping and Receiving Building, which will tentatively be occupied in late summer 2009. Since multiple systems are involved, this Modification Record will be used as the initiating document to ensure all systems related to emergency response have been identified. These systems include: Evacuation Horns, Fire Protection, Intercom System, Emergency Electrical Power, and Normal Electrical Power. The following addendums to previously approved Modification Records will be used to document changes to each of these systems: Modification Record 90-1; Addendum 2 - Evacuation Horns in Shipping and Receiving Building Modification Record 03-1; Addendum 2 - Fire Protection in Shipping and Receiving Building Modification Record 01-2; Addendum 3 - Intercom System in Shipping and Receiving Building Modification Record 01-9; Addendum 3 - Emergency Electrical Power in Shipping and Receiving Building Modification Record 04-5; Addendum 7 - Normal Electrical Power in Shipping and Receiving Building It should be noted that the functions of the existing Mail Trailer will be integrated into the new Shipping and Receiving Building. The installation of this trailer was documented in Modification Record 01-12. A letter to Modification Record 01-12 will be drafted to state that the trailer will be removed following the transfer of its functions to the new building. This Modification Record will NOT provide suggested revisions to the Emergency Procedures. Why a Short Form is appropriate. (At least one of four reasons listed on Page 1, with justification) The short form of the Modification Record is appropriate because this is a modification to a non-safety system that requires documentation and review only (Reason No. 4). 2 Attachment 8.1 ORIGINAL

ATTACHMENT 7 ORIGINAL AP-RO-1 15 11-2 Revision 6l 11-2_Revision_6 Modification Number: MODIFICATION DESCRIPTION Provide a concise description of the system change. Include any proposed PRE-OPERATIONAL TESTS required for this change. (If additional pages are necessary, insert after this page.) This Modification Record documents the replacement of the existing Cooling Tower. The replacement of the Cooling Tower will consist of demolition of the existing wood structure, removal of an asbestos containing basin liner, conversion of the existing basin to a structural slab, installation of a steel elevating structure, installation of three (3) current generation stainless steel modular towers, installation of associated piping and electrical components and supporting instrumentation, as well as repairs to the existing mechanical building. The existing Cooling Tower is a wood-framed, induced-draft, cross-flow type with three cells and two-speed fan assemblies for each cell. The tower is designed to cool 4,632 gallons of water per minute to a temperature of 87 degrees-F from an initial temperature of 104 degrees-F at a maximum wet bulb temperature of 77 degrees F. This tower structure was last renewed in 1998, along with several repair and preservation efforts since, and is approaching the end of its service life. When the detennination was made to fund the replacement tower, a design engineer was contracted through Campus to evaluate and recommend the proper approach and end result, based on the current and projected cooling needs of MURR. The results of the design engineer's conclusions are best shown in the attached set of drawings, and further detailed in the project specifications (not attached). To support this work, Modification Record 09-4; Cooling Tower Temporary Cooling has been implemented, providing temporary cooling to the Secondary Coolant System. This allows continued operation of the Reactor on a normal schedule during the performance of this replacement work. Since multiple systems are involved, this Modification Record will be used as the initiating document to ensure all changes to supporting systems or subsystems are documented. This Modification Record will primarily document the Structural, Mechanical and Electrical changes associated with this change. The following Modification Records and addendums to previously approved Modification Records will be used to document changes to each of these systems: Modification Record 98-2; Addendum I - Sulfuric Acid System Changes in Support of Cooling Tower Replacement Modification Record 03-3; Addendum 3 - Fire Protection System Changes in Support of Cooling Tower Replacement Modification Record 11-3; Data Acquisition and Monitoring System for Secondary Coolant System (Modification Description continued on page 2a.) Why a Short Form is appropriate. (At least one of four reasons listed on Page 1, with justification) The short form of the Modification Record is appropriate because this is a modification to a non-safety system that requires documentation and review only (Reason 4). 2 Attachment 8.1
ATTACHMENT 7 ORIGINAL AP-RO- 115 Revision 6 Modification Number: 11-2 MODIFICATION DESCRIPTION (con't) Scope of Work DEMOLITION Demolition will be performed in accordance with the 'D' series sheets of the attached drawings. It will consist first of connecting and ensuring operable the Temporary Cooling Towers. Then piping, instrument and electrical services will be disconnected, along with the Fire Protection Deluge System. The Bulk Acid Tank will be emptied and temporarily relocated. Removal of the existing tower structure will proceed from the west end. When the major structure has been removed, an existing asbestos-containing liner will be removed from the concrete basin and properly disposed of. The concrete basin walls will be cut down to form a flat slab from the basin. Additional demolition work will include removal of the Acid Day Tank and associated piping and removal of the asbestos-containing transite panel wall that currently forms the north wall of the Cooling Tower building mechanical room. STRUCTURAL Structural work will be performed in accordance with the 'S' series sheets of the attached drawings. It will consist first of anchoring a prefabricated, galvanized steel structural box frame on the footprint of the basin converted to slab. This steel structure will be primarily bolted members of I-beams sitting on steel columns with welded angle braces. The steel structure will provide a 7-foot elevation for the new tower modules to sit on. The tower modules will consist of three SPX Marley towers. These towers are Model NC8414, are primarily stainless steel construction with PVC integral fill sheets, and are constructed to have all piping connections be made from underneath the towers. They will remain as induced-draft, cross-flow type with three cells and two-speed fan assemblies for each cell. The fill sheets integrate the inlet louver, fill drip surface area and drift eliminator inner section on one stamped sheet. These towers will have fan motors mounted inside the airstream with a fan access platform for inspection and maintenance of the fan drivetrain. The towers will be shipped as a lower and upper module, and will be installed by stacking and bolting the two modules for each of the three cells on the steel support frame. Other supporting structures will be installed following installation of the tower modules such as access platforms and ladders as well as handrail restraints at the top of the tower modules. The west wall of the Cooling Tower building will be evaluated for necessary repairs and finish options, once exposed. Currently, the north and center access doors are expected to be blocked, leaving one access door on the south as an egress route from the electrical room. A concrete block wall will be installed at the north wall of the Cooling Tower building mechanical room. MECHANICAL Mechanical work will be performed in accordance with the 'M' series sheets of the attached drawings. It will consist of installing piping and valves to connect the three tower cells to the existing piping connections. (Modification Description continued on page 2b.) 2a Attachment 8.1
ATTACHMENT 7 ORIGINAl' AP-RO-1 15 Revision 6 Modification Number: 11-2 MODIFICATION DESCRIPTION (con't) Several new mechanical features are described as follows:
- 1) The existing six flow distribution valves will be replaced with three current generation flow distribution valves, one for each tower inlet.
- 2) Since the three tower cells will have three independent basins, additional equalizing piping and valves will be provided to ensure basin levels remain roughly equal.
- 3) The existing makeup water distribution tree will be modified to provide independent isolation and bypass features for both the Auto-makeup Valve and the makeup flowmeter.
- 4) The existing makeup flowmeter will be replaced with a larger capacity Badger flowmeter, but remain compatible with the existing pulse cycle instrumentation output.
- 5) Makeup water will no longer be fed to a common sump; therefore each of the three basins will have independent makeup float valves and independent level sensing systems.
- 6) Each basin will be provided with independent overflow and drain piping.
- 7) The existing acid addition drip system will be replaced with an integral injection quill in the common cold water header.
- 8) Several temperature and pressure sensing field devices will be installed as described in the attached drawings. Except where noted here, this instrumentation will be used for monitoring purposes only and will be described in another Modification Record.
ELECTRICAL Electrical work will be performed in accordance with the 'E' series sheets of the attached drawings. It will consist of installing new 200-amp disconnects adjacent to each tower cell, and feeding fan power from the existing fan controllers in MCC-1. Control of the fans will remain as two-speed manual control from the Control Room, with reversing control at each motor controller. Several new electrical features are described as follows:
- 1) A space heater powered from LP-41 installed in each fan motor will be energized any time that fan motor is secured.
- 2) An additional fan logic interlock will utilize a capacitive sensor to prevent a fan from running if its gearbox oil level is not high enough.
- 3) The existing low sump cutout float will be replaced with a low header discharge pressure switch.
- 4) The existing steam heat for basin freeze protection will be replaced with 30-kw electrical heaters placed in each basin, and controlled by independent thermostats. These heaters will be powered from an existing spare breaker in MCC-1 as shown on the 'E' series drawings attached.
- 5) Six lamp posts will be mounted on top of the new tower structure to provide lighting.
- 6) A lightning protection system will be installed on the lamp posts described above, and will have a Surge Protector Device installed in MCC-] as shown on the 'E' series drawings attached.
This work is being performed under Campus Project number: CPI 10731. 2b Attachment 8.1

Subject:
Cooling Tower Replacement Project In preparation for and during the cooling tower replacement project MURR Health Physics analyzed four separate putential radioactive waste streams prior to demolition. These were:
- 1. Cooling tower sump sludge
- 2. Cooling tower sump liner material
- 3. Underground secondary suction header soil sample
- 4. Underground secondary suction header tritium analysis from soil sample.
Items 1-3 above were analyzed for gamma identification using the HP germanium counting system in lab 213 while item 4 was analyzed for H-3 due to leakage from the secondary system header using the Packard 2300 LSC system. In all cases radioactive materials evidence was negative, as there were no isotopezs identified above background levels. Should you require more or additional information, please do not hesitate to contact me. Cc: John Fruits

ATTACHMENT 7 OP-RO-480 Revision 14 I Date: SECONDARY COOLANT SYSTEM VALVE LINE-UP CHECKSHEET This checksheet will be completed when required by the Lead Senior Reactor Operator (LSRO). The operators performing the check will independently verify the position of each valve and indicate the verification by initialing the chccksheet. Where appropriate, the position of throttled valves are shown on a permanent tag secured to the valve. Note the throttled valve's position on the checksheet. Under the direction of the LSRO, a valve may be positioned other than listed on this checksheet. If this is required, the operators must ensure that the valve is in the desired position and indicate this position on this checkshect. If this change of position is not covered by a procedure in use, for example an RTP, SMP, or Work Package, which would return the valve to the normal operating position, then the LSRO will issue and place a Danger Tag on the valve for the duration of time the valve is in the out-of-normal position.

Include any proposed PRE-OPERATIONAL TESTS required for this change. (If additional pages are necessary, insert after this page.) Several systems within the facility are in place to ensure a prompt and effective response from MURR staff to an emergency or abnormal condition. These systems will also be required to be in place in order to safely occupy the Eastward Expansion of the MURR Industrial Building (MIB). Since multiple systems are involved, Modification Record 14-01 will be used as the initiating document to ensure all systems related to emergency response have been identified. The following Modification Records will be used to document changes to the individual systems:
" Modification Record 90-01; Addendum-62"- Evacuation Horns in MIB Eastward Expansion " Modification Record 03-03; Addendum 05 - Fire Protection in MIB Eastward Expansion
- Modification Record 01-02; Addendum 11 - Intercom System in MIB Eastward Expansion
- Modification Record 14 Normal Electrical Distribution in MIB Eastward Expansion It should be noted that the functions of the existing MIB will not be changed. The Eastward expansion of MIB will serve to house additional space for projects and storage. A future modification record will document further changes to construct usable laboratory spaces within the expansion.
This Modification Record will NOT provide suggested revisions to the Emergency Procedures. Why a Short Form is appropriate. (At least one of four reasons listed on Page 1,with justification) The short form of the Modification Record is appropriate because this is a modification to a non-safety system that requires documentation and review only (Reason No. 4). 2 (MRIGINAI Attachment 8.1

Subject:
Construction Details Modification Record 14-01 documented the construction of the MURR Industrial Building (MIB) Eastward Expansion. This letter documents the construction methods and details. The expansion is not directly mentioned in the Hazards Summary Report. The MIB is a part of the Laboratory Building. The extent of inclusion in the Hazards Summary Report is to show the expansion on the building floor plan drawings. The grade level floor is poured concrete designed for a 125 lb./ft2 live load with additional steel and concrete framing to support four (4), 100,000 lb. hot cells positioned next to each other anywhere along the North-South direction. The steel and concrete structure rests on pilings driven to bedrock. The below grade floor is also poured concrete designed to handle a 125 lb./ft.2 live load, additionally, the floor can handle a 10,000 lb. load on a 6 ft. x 6 ft. base plate. The East outer wall of the building has a masonry shield wall in part of the building as shown on the attached print. This is in place to reduce possible dose to the public from the cask loading taking place in the cask loading side of the hot cells. This wall is concrete block with all voids filled with grout. This expansion will provide an additional 1440 ft2 and 1432 ft2 of net usable space on the grade, and the below grade levels respectively. The building is construction type II-B. This type of construction utilizes non-combustible materials that do not provide a burn rating. There is an external drain tile sump with visual alarm indication of sump high level. This building also has heating ventilation and air conditioning, domestic cold water, domestic hot water, vacuum, and compressed air.

Include any proposed PRE-OPERATIONAL TESTS required for this change. (If additional pages are necessary, insert after this page.) This modification record serves to document the construction of the usable laboratory spaces within, and extension of MURR systems to, the dedicated laboratory facility in the new eastward expansion to the MURR Industrial Building (MIB). This laboratory contains three adjoined and inter-connected hot cells located on the grade level (HC-11A, HC-11B, and HC-11C). HC-11A and HC-11B have 200mm (7.9 in) of vertical lead shielding while HC-11C has 100mm (3.9 in) of vertical lead shielding. The area to the rear of the cells, the cask loading area (Room 299U), is where the cell support facilities and equipment are located and where cell inputs and outputs occur. The area in front of the hot cells, the operator area (Room 299T), is where the cell windows, manipulators, glove boxes and controls are located. There is an additional laboratory (Room 299V) on grade level and a full basement under the expansion (Room 199). The following Modification Records will be used to document the individual systems:
" Modification Record 90-01; Addendum 03 - Evacuation Horns in MIB Eastward Expansion " Modification Record 01-02; Addendum 11 - Intercom System in MIB Eastward Expansion " Modification Record 03-03; Addendum 06 - Fire Protection in MIB Eastward Expansion

Include any proposed PRE-OPERATIONAL TESTS required for this change. (If additional pages are necessary, insert after this page.) This modification record documents the installation of radioactive exhaust ventilation in the newly expanded MURR Industrial Building (MIB). The system consists of charcoal and high efficiency particulate air (HEPA) filter banks, constant volume control valves (CVCVs), hot cell ventilation exhaust fans, flow and pressure measurement devices, and associated ducting and dampers. Exhaust air from the containment and laboratory buildings are discharged to atmosphere through the exhaust stack by either exhaust fan EF-13 or EF-14 in the west tower. Either one or the other (EF-13 or EF-14) exhaust fan is on at all times. The other fan is a standby. Failure of the in service fan automatically activates the standby and also activates a warning light in the control room. A failure of both fans activates an alarm in the control room. Static pressures are limited by a pressure sensitive relief damper that begins to open at 8" H20 and is full open at 10" H20. The ventilation system, which will support the MIB Expansion, is designed to perform the following radiological control functions: Maintain Rooms 299T, 299U, and 299V at a slightly negative pressure with respect to the surrounding areas to prevent the spread of radioactive contamination; Maintain hot cells HC-11A, HC-11B, and HC-1 1C at a negative pressure to prevent the spread of radioactive contamination; Provide the necessary charcoal and HEPA filtration to ensure radioactive airborne being released to the environment are kept at minimum concentrations; and (Continued on page 2a) Why a Short Form is appropriate. (At least one of four reasons listed on Page I, with justification) The short form of the Modification Record is appropriate because this is an Addendum to an existing, previously approved Modification Record (Reason 1) and this is a modification to a non-safety system that requires documentation and review only (Reason 4). 2 Attachment 8.1
ATTACHMENT 10 qlpjp3 5AL Revision 8 Modification Number: 88-07; Addendum 3 MODIFICATION DESCRIPTION (cont.) provide continuous monitoring of all radioactive airborne releases discharged through the MIB Expansion ventilation exhaust system. Air exiting the MIB Expansion through the exhaust ventilation system is continuously monitored for airborne activity by a radiation monitoring system downstream of all of the hot cell and room filtration systems. The ventilation system will be utilized in multiple areas of the MIB Expansion as follows: Room 299T The air will be exhausted through a CVCV, HEPA filter and a (selected) parallel charcoal filter (one filter on service - one in standby) into the facility main ventilation exhaust system at a rate of approximately 250 cfm. Room 299U The air will be exhausted through a CVCV and the same HEPA and parallel charcoal filter system which also supports Room 299T and then into the facility main ventilation exhaust system at a rate of approximately 100 cfm. Room 299V The air will be exhausted from the room through a fume hood, a CVCV, HEPA filter and a (selected) parallel charcoal filter (one filter on service - one in standby), and then into the facility main ventilation exhaust system at a rate of approximately 450 cfm. Hot Cells HC-II A, HC-I IB, and HC-11 C The exhaust ventilation for hot cells HC-I IA, HC-i lB and HC-I 1C will consist of an intricate combination of HEPA and charcoal filtration systems, two (2) exhaust fans, and flow measurement and control devices. The exhaust systems for each cell will combine to form a common header; each hot cell will have its own independent filtration system. Air will be exhausted from each hot cell through an internal parallel set of charcoal filters, then through a (selected) external parallel charcoal and HEPA filtration bank (one bank on service - one in standby), a CVCV, a second (selected) parallel charcoal filter (one filter on service - one in standby), and then through a (selected) parallel exhaust fan into the facility main ventilation exhaust system at a rate of approximately 60 cfm (one fan operating - one in standby). (Continued on page 2b) 2a Attachment 8.1
ATTACHMENT 10 AP4.'IiGI\ t Revision 8 Modification Number: 88-07, Addendum 3 MODIFICATION DESCRIPTION (cont.) The exhaust fans will be 3 HP centrifugal models, each controlled by an Adjustable Speed Drive (ASD) that will maintain a constant flow rate through the system based on a control signal from a pressure transmitter located between the CVCV and the second set of charcoal filters. The fans will be powered from lighting panel LP-46 and will be designated HC-1 I Exhaust Fans No. I and 2 (HC- I I EF-I and HC-l I EF-2). A loss of electrical power to HC- 11 EFI and 2 will not cause an immediate unsafe condition because the facility ventilation exhaust system will continue to operate and maintain a negative cell pressure. There are two glove boxes mounted to the hot cells; one on the north end of HC-I IA and one on the south end of HC-I IC. Air will be exhausted from each glove box through a charcoal filter and then a HEPA filter. The exhaust ducting for each glove box will connect to the hot cell common exhaust header downstream of the hot cell filtration systems. Room 199 Exhaust ventilation will be available in the basement to support future addition of loads within room 199. Filtration and room differential pressures will be monitored by a combination of Magnehelic& gauges, pressure transmitters, and flow stations. The Magnehelic gauges are used to measure differential pressure across the filtration systems as well as measure differential pressure in Rooms 299T, 299U and 299V. Two of the pressure transmitters will be used to control HC-1 I EF-1 and HC-1 I EF-2 fan speed. 2b Attachment 8.1

ATTACHMENT 11 viR IGINAL AP-RO-I 15 Revision 8 Modification Number: 90-1; Addendum 3 MODIFICATION DESCRIPTION Provide a concise description of the system change. Include any proposed PRE-OPERATIONAL TESTS required for this change. (If additional pages are necessary, insert after this page.) This Modification Record documents changes to the facility Evacuation System that are necessary in order to safely occupy the MURR Industrial Building Eastward Expansion (MIB East). This is part of an effort to ensure all systems relating to emergency response are extended to MIB East. The initiating document for installation/extension of those systems is Modification Record 14-01, Interfacing MURR Systems with the MIB/BOB Eastward Expansion. Modification Record 90-1, "Evacuation Horns" provided for additional evacuation horns and lights as part of a major reconfiguration of the system in 1990. The MURR Evacuation System serves to actuate the MURR Containment Isolation System, and to provide an audible and visible indication via horns and lights to evacuate the facility via the nearest exit. The system can be manually actuated from either the control room (Room 302) or the facility lobby (Room 210). There is no automatic means to actuate the Evacuation System. The existing Evacuation System horns and lights are powered from the Emergency Lighting Panel in the Laboratory building and the North Office Addition Emergency Lighting Panel in NOA. Previous Modification Record 90-1; Addendum 1 stated that horns and lights may be added to the Evacuation System with Reactor Manager's approval, and without a separate Modification Record. This allows for reconfiguring as needs change within the facility. This Modification Record is being used to document a larger addition to the system as a result of the construction of the new structure. To ensure a prompt and effective response from MURR staff to an emergency or abnormal condition, the MURR Evacuation System will be extended to MIB East. This will require the addition of three (3) evacuation horns (see attached drawing). Why a Short Form is appropriate. (At least one of four reasons listed on Page 1, with justification) The short form of the Modification Record is appropriate because this is an addendum to a previously reviewed and approved Modification Record (Reason No. 1). 2 Attachment 8.1

ATTACHMENT 12 AP-RO-1 15 Revision 8 Modification Number: 01-02; Addendum MODIFICATION DESCRIPTION Provide a concise description of the system change. Include any proposed PRE-OPERATIONAL TESTS required for this change. (If additional pages are necessary, insert after this page.) This Modification Record documents changes to the MURR Intercommunication and Paging System that will enhance communications in the MURR Industrial Building (MIB) expansion through the addition of paging speakers. The installation of an additional amplifier will reduce loading on existing paging speaker amplifiers, and provide capacity for future system growth facility-wide. It also documents the addition of a speaker in the Laboratory Building, as well as correcting minor discrepancies found during a speaker location audit. Modification Record 01-02 documented installation of the current MURR Intercommunication and Paging System. Addenda 1-10 documented modifications and additions to that system. The MURR facility utilizes two principal communication systems: a computerized telephone system, which allows several different telephones to originate a page, and an intercommunication system that allows two-way communication between a master station in the Control Room (Room 302) and any of several staff stations. To ensure a prompt and effective response from MURR staff to an emergency or abnormal condition, the MURR Intercommunication and Paging System will be extended to the Rooms 199T, C299U, 299U, 299T, and 299V. This will require the addition of six (6) paging speakers as described in the attached revision to the Hazards Summary Report, Table 7.2. (Modification Description continued on Page 2a) Why a Short Form is appropriate. (At least one of four reasons listed on Page I, with justification) The short form of the Modification Record is appropriate because (a) this is an addendum to an existing, previously reviewed and approved Modification Record (Reason No. 1), and (b) this is a modification to a non-safety system that requires documentation and review only (Reason No. 4). 2 Attachment 8.1
ATTACHMENT 12 AP-RO-1 15 Revision 8 Modification Number: 01-02: Addendum I I MODIFICATION DESCRIPTION (cont.) The existing Laboratory Building and MIB portions of the paging system are supported by a single BOGEN model TPU-250 watt amplifier. This amplifier is currently supplying power to 72 paging speakers totaling 204.39 watts, approximately 81.76% of rated amplifier capacity. The existing North Office Addition (NOA) portion of the paging system is supported by a BOGEN model TPU-60 watt amplifier. This amplifier is currently supplying power to 38 paging speakers totaling 49 watts, approximately 81.6% of rated amplifier capacity. With the proposed modifications, the BOGEN TPU-60 amplifier currently installed in NOA will be replaced by a BOGEN TPU-250 (the same model as the Laboratory Building amplifier). This change will reduce the percent load on the NOA amplifier to approximately 19.67% rated amplifier capacity with the same 49 watt loading. The Laboratory Building amplifier (BOGEN TPU-250) will not be replaced; however existing speaker loads for the MIB will be removed from the Laboratory Building amplifier. This will reduce the loading on the Laboratory Building amplifier to 63 speakers totaling 172.39 watts, approximately 68.96% of rated amplifier capacity. The BOGEN TPU-60 watt amplifier removed from NOA will be installed in the MIB. This amplifier will power the eight MIB loads transferred from the Lab Building amplifier as well as six additional speakers required for the eastward expansion of the MIB. This amplifier will have the load from these 14 speakers totaling 27 watts, approximately 45% of rated amplifier capacity. In addition to the MIB expansion area speakers and amplifier installation, this modification record will also document the installation of one (1) additional speaker in room 213 powered by the Laboratory Building amplifier. While creating the documentation for this modification record, a speaker location audit was performed, and minor discrepancies were noted. These discrepancies are being documented as follows: Speaker Location HSR Table 71. Corrective Action Room 246 Not Listed Installation has been verified and documented here Room 225 Not Listed Installation has been verified and documented here Corridor C299A Room 299 Room designation verified and documented here With this modification, all paging system amplifier loadings will be below the recommended 80% maximum loading thereby making each amplifier more reliable, and providing capability for future system expansion needs. Along with the reduced loading of individual amplifiers, the addition of a third amplifier reduces the impact of a failure of a single amplifier. 2a Attachment 8.1

The Emergency Electrical Power System is designed to provide emergency electrical power to key essential reactor components in order to monitor systems and assure personnel safety should the facility experience a loss of normal electrical power. The system includes an Emergency Diesel Generator (EDG), an Auto-transfer bus system, the Emergency Distribution Center (EDC), its various loads, panels, and low voltage sub-panels. The Emergency Electrical Power System currently provides power to facility loads such as Exhaust Fans EF-13 and EF-14, the EDG Distribution Panel, exit and stairway lighting, Intercommunication System, Off-Gas Stack Monitor, specific reactor related loads through an Uninterruptible Power Supply (UPS), and others as described in the Hazards Summary Report and its addenda. This modification consists of adding one 120 V circuit to breaker 15 of the 120/208 panel "Diesel Room Distribution Panel" located in room 231 E. The circuit will be used to provide emergency lighting for the various rooms within the MIB Eastward Expansion. Why a Short Form is appropriate. (At least one of four reasons listed on Page I, with justification) The short form Modification Record is appropriate because this is an Addendum to an existing Modification Record (Reason 1) and this is a modification to a non-safety system and requires documentation and review only (Reason 4). 2 Attachment 8.1 (DRIGINAL

Does the proposed activity involve a change to an SSC that adversely affects a design function described in the HSR? No. The connection of these new circuits to the electrical system will not involve changes to an SSC that could adversely affect a design function described in the HSR. The addition and utilization of these new circuits in the MIB Eastward Expansion is within the design function of the Emergency Electrical Distribution System and will not result in any electrical panel loading exceeding the 80% loading requirement. These types of loads are specifically specified in the HSR for this system.
- 2. Does the proposed activity involve a change to a procedure that adversely affects how HSR described SSC design functions are performed, controlled, or tested?
No- The connection of thepse new circuit to the Emergency Electrical Systerm will not involve any procedure changes related to HSR described SSC design functions. These new circuits do affect any SSC design functions, and are wholly within the design function of that system. Reactor Emergency Procedures (REPs) related to electrical power loss and the Emergency ElectricalAystem are unaffected by this change.

Include any proposed PRE-OPERATIONAL TESTS required for this change. (If additional pages are necessary, insert after this page.) This Modification Record documents the installation of a Fire Protection System in the new MURR Industrial Building (MIB) eastward expansion. It is part of an effort to ensure all systems relating to emergency response are extended to the MIB expansion. The initiating document for installation/extension of those systems is Modification Record 14-01, Interfacing MURR Systems with the MIB Eastward Expansion. The facility's Fire Protection System is briefly described in Section 7.2.4 of the HSR. The system is designed to protect the facility and staff, and to mitigate any property loss in the event of a fire. It consists of a combination of several subsystems: (1) a Detection System including multiple sensors, pull stations, and monitoring panels, and (2) a Suppression System including a pre-action system, a dry fire main system, a traditional flooded sprinkler system, and a ventilation damper system. The new system in MIB Expansion will likewise provide both functions as well. This phase of construction, as documented in Modification Record 14-01, will only provide fire suppression to the stairwell and mezzanine areas of the MIB eastward expansion. Fire suppression for the remainder of the building will be installed with the next phase of construction and will be documented with the construction of laboratory spaces within the expanded MIB. The fire detection system for the entire MIB expansion will be provided at that time as well. The expansion will utilize a traditional sprinkler system. The system is pressurized with water and will sprinkle the area when a sprinkler head opens due to high heat. The system is to be supplied from the 3" Fire Main in the existing MIB structure. (Modification Description continued on Page 2b) Why a Short Form is appropriate. (At least one of four reasons listed on Page 1,with justification) The Short Form of the Modification Record is appropriate because this is and Addendum to a previously reviewed and approved Modification Record (Reason No. 1), and is a modification to a non-safety system that requires documentation and review only (Reason No. 4). 2 Attachment 8.1 WJRIGINAL

Include any proposed PRE-OPERATIONAL TESTS required for this change. (If additional pages are necessary, insert after this page.) This Modification Record documents the installation of additional Fire Protection System equipment in the newly constructed MURR Industrial Building (MIB) eastward expansion. It is part of an effort, as the lab spaces are constructed, to ensure all systems relating to emergency response are extended to the MIB expansion. The initiating document for installation/extension of those systems is Modification Record 14-01; Addendum 1, Construction of Usable Laboratory Spaces Within The Expanded MURR Industrial Building. The facility's Fire Protection System is briefly described in Section 7.2.4 of the HSR. The system is designed to protect the facility and staff, and to mitigate any property loss in the event of a fire. It consists of a combination of several subsystems: (1) a Detection System including multiple sensors, pull stations, and monitoring panels, and (2) a Suppression System including a pre-action system, a dry fire main system, a traditional flooded sprinkler system, and a ventilation damper system. The new system in the MIB expansion likewise provides two functions: (1) a Detection System that provides an early warning of an actual or potential fire condition by a combination of heat, smoke, and remote manual devices, and (2) a Suppression System that incorporates a normal sprinkler system. All of these systems and devices combine to form a complete Fire Detection/Suppression System for the MIB Eastward Expansion, and are integrated with the remainder of the MURR Fire Detection/Suppression System at the central control panel in the Main Lobby. The MIB Eastward Expansion Fire Detection System is a composite of thermal, photoelectronic, and ionization-type sensors, tamper switches, flow switches, and manual pull stations. The central control panel and remote repeater station continuously monitor each system component. (Continued on page 2a) Why a Short Form is appropriate. (At least one of four reasons listed on Page 1, with justification) The Short Form of the Modification Record is appropriate because this is and Addendum to a previously reviewed and approved Modification Record (Reason No. 1), and is a modification to a non-safety system that requires documentation and review only (Reason No. 4). 2 Attachment 8.1
ATTACHMENT 15 AP 1IGINAL Revision 8 Modification Number: 03-03, Add 6 MODIFICATION DESCRIPTION (con't) The central control panel is located in the Common Lobby and the repeater station remains in the reactor control room. These stations will annunciate an alarm if any component is not in its normal condition. The MIB Eastward Expansion has a traditional sprinkler system. The system is pressurized with water and will sprinkle the area when a sprinkler head opens due to high heat. The system is supplied from the Fire Protection System in place in the existing portion of the MIB. 2a Attachment 8.2

Where appropriate, the positions of throttled valves are shown on a permanent tag secured to the valve. Note the throttled valve's position on the checksheet. Under the direction of the LSRO, a valve may be positioned other than listed on this checksheet. If this is required, the operators must ensure that the valve is in the desired position and indicate this position on the checksheet. If this change of position is not covered by a procedure in use, for example an RTP, SMP or Work Package, which would return the valve to the normal operating position, then the LSRO will issue and place a Danger Tag on the valve for the duration of time the valve is in the out-of-normal position.

ORTI4thILNT 16 AP-RO-1 15 04-0;'Revision Adendm 8 04-03; Addendum: Modification Number: MODIFICATION DESCRIPTION Provide a concise description of the system change. Include any proposed PRE-OPERATIONAL TESTS required for this change. (If additional pages are necessary, insert after this page.) This Modification Record documents the changes required to extend facility Liquid Radioactive Waste (LRW) system to the Eastward expansion of the MURR Industrial Building (MIB). BACKGROUND Modification Record 04-03; "Liquid Radioactive Waste Modification" upgraded the original system of gravity drains and below grade retention system with an above ground drain header and retention system. Modification Record 04-03; Addendum 1 "Liquid Radioactive Waste System in MURR Industrial Building" incorporated the MIB LRW system into the facility LRW system. EXISTING FACILITY SYSTEM All drains for potentially contaminated liquids are delivered to a LRW retention system in the below grade area of the reactor building. The liquid waste retention system consists of three tanks of approximately 5000 gallons capacity each, and one tank of approximately 550 gallons, transfer pumps, filter banks, and associated piping and valves. In addition the MIB houses three additional 150 gallon tanks which also may be used to hold LRW. Liquid waste is retained or chemically treated until an assay indicates activity levels are less than the limits for disposal specified in 10 CFR 20 and then is released into the sanitary sewerage. In addition to having activity levels measured, all liquid waste is circulated through a filter bank to ensure no suspended solids of visible size are present prior to release. continued on Page 2a Why a Short Form is appropriate. (At least one of four reasons listed on Page I, with justification) The Short Form of the Modification Record is appropriate because this is an Addendum to a previously reviewed and approved Modification Record (Reason No. 1), and is a modification to a non-safety system that requires documentation and review only (Reason No. 4). 2 Attachment 8.1
AP-RO-I 15 Revision 8 Modification Number: 04-03; Addendum 2 MODIFICATION DESCRIPTION (cont.) SCOPE OF WORK This modification will require two lift stations and an elevator sump to be installed in order to service the MIB Eastward Expansion drain needs. The eyewash station and sink located in corridor C229U will be connected to a lift station (small retention tank and discharge pump) which will discharge to the larger duplex lift station located in the MIB eastward expansion basement (Room 199). The basement duplex lift station will also receive condensate water from the air handling units and cooling coils and the Room 299V sink. The elevator sump pump will discharge directly to the MIB eastward expansion LRW header. The loads and discharge piping arrangement for these lift stations are illustrated on the attached schematic (Page 2b). The electrical work associated with the installation of the lift station and sink are included in the electrical analysis and documentation of Modification Record 14-02; Addendum 1. 2a Attachment 8.1

ATTACHMENT 16 OP-RO-741 Revision 15 Date: OPERATIONAL WASTE TANK SYSTEM VALVE LINE-UP This checksheet will be completed when required by the Lead Senior Reactor Operator (LSRO). The operators performing the check will independently verify the position of each valve and indicate the verification by initialing the checksheet. Where appropriate, the positions of throttled valves are shown on a permanent tag secured to the valve. Note the throttled valve's position on the checksheet. Under the direction of the LSRO, a valve may be positioned other than listed on this checksheet. If this is required, the operators must ensure that the valve is in the desired position and indicate this position on this checksheet. If this change of position is not covered by a procedure in use, for example an RTP, SMP, or Work Package, which would return the valve to the normal operating position, then the LSRO will issue and place a Danger Tag on the valve for the duration of time the valve is in the out-of-normal position.

Include any proposed PRE-OPERATIONAL TESTS required for this change. (If additional pages are necessary, insert after this page.) This modification record documents the expansion of the Normal Electrical Distribution System for the Eastward expansion to the MURR Industrial Building. The power will be supplied by HVP-3 and the 120/208V Distribution Center 1. In order to provide sufficient electrical capacity for future laboratory construction, the Eastward Expansion of the MURR Industrial Building will house 3 new electrical distribution panels; HVP-3A, LP-46, and HC-1 1 Electrical Power Panel. The new high voltage panel HVP-3A will be supplied from a 200 Amp 3 Phase breaker off of HVP-3. The HC-1 1 Panel and LP-46 panels will be supplied from individual 200 Amp 3 Pole breakers off of 120/208V Distribution Center 1. Load has been analyzed for both the 120/208V Distribution Center 1 and the HVP-3 to ensure that new loads will be within the capacity of the existing panels. Both panels were found to have sufficient capacity to provide the necessary loads, and stay below a 80% overall panel loading. Why a Short Form is appropriate. (At least one of four reasons listed on Page 1, with justification) The short form of the Modification Record is appropriate because this is a modification to a non-safety system that requires documentation and review only (Reason No. 4). 2 O~RIGINALj' Attachment 8.

ATTACHMENT 1a IGINAL AP-RO-115 14-04 Modification Numbcr: MODIFICATION DESCRIPTION Provide a concise description of the system change. Include any proposed PRE-OPERATIONAL TESTS required for this change. (If additional pages are necessary, insert after this page.) This Modification Record documents the installation of a permanently installed Lab Impex Iodine Duct Monitoring System for detection of radioactive airborne iodine discharged through the MURR Industrial Building (MIB) Expansion ventilation system to the Laboratory and Containment Building Exhaust Ventilation System. The installation of the MIB ductwork is included in Modification Record 88-07 Addendum 3, "Exhaust Ventilation in MIB Eastward Expansion." The monitoring equipment consists of a single-channel radiation detection system designed to measure airborne concentrations of radioactive iodine in the exhaust air that is sampled by a shrouded probe in the ventilation ducting downstream of all of the hot cell and room filtrations systems. The system will be capable of measuring real-time exhaust flow rate as its basis for release concentrations. A pitot tube measurement device and flow transmitter will provide input to the system. This provides continuous monitoring of all radioactive iodine releases discharged through the MIB Expansion ventilation exhaust system. The system will also be capable of providing measurement data, via a network connection, such as concentration as a function of time, average concentration for specific time periods, and total releases for specific time periods. This historical data will be used to determine possible filtration degradation over time. It should also be noted that this data will not be used to determine facility stack effluent release concentrations. That data will continue to be determined using the existing facility exhaust stack monitor systems. Historical data will be maintained by Health Physics personnel via an integral database. The database output may be accessed via a network terminal installed in the Health Physics office. At the discretion of the facility, this output may also be remotely accessed by the manufacturer via Internet connection for troubleshooting purposes. All database outputs are for monitoring only, and provide no control functions. Additional details of the system are provided in the listed attachments: Attachment 1 MURR Print 2777, "MIB East Addition Exhaust Schematic" Attachment 2 MAN0042, "CMS-1 Iodine Operation and Maintenance Manual" Attachment 3 MAN0104, "SmartMCA Operation and Maintenance Manual" Why a Short Form is appropriate. (At least one of four reasons listed on Page 1, with justification) A short for modification is appropriate because this modification is to a non-safety system, for documentation and review purposes only.

The system will be capable of measuring real-time exhaust flow rate as its basis for release concentrations. A pitot tube measurement device and flow transmitter will provide input to the system. This provides continuous monitoring of all radioactive iodine releases discharged through the MIB Expansion ventilation exhaust system. The system will also be capable of providing measurement data, via a network connection, such as concentration as a function of time, average concentration for specific time periods, and total releases for specific time periods. This historical data will be used to determine possible filtration degradation over time. It should also be noted that this data will not be used to determine facility stack effluent release concentrations. That data will continue to be determined using the existing facility exhaust stack monitor systems. Historical data will be maintained by Health Physics personnel via an integral database. The database output may be accessed via a network terminal installed in the Health Physics office.

ATTACHMENT 19 ORIGINAL AP-RO-l 15 Revision 3 75-16: Addendum 4 Modification Number: MODIFICATION DESCRIPTION Provide a concise description of the system change. Include any proposed PRE-OPERATIONAL TESTS required for this change. (If additional pages are necessary, insert after this page.) This Modification Record documents a revision to the Reactor Safety System Monitoring Circuit ("White Rat") Panel. New overlays will reflect the addition of a series contact in both the "green leg" and "yellow leg" of the Reactor Safety System. The new contacts provide a SCRAM function from the Flux-Trap Irradiations Reactivity Safety Trip (FIRST) instrument channel as described in the FIRST Preliminary Long-Form Modification Record. This modification does not change the function of the "White Rat" Panel itself. The Reactor Safety System Monitoring Circuit was originally installed in October 1973, under Modification Record 72-3, as a way of monitoring the reactor scram circuit for spurious scrams that were too short in duration to be sensed by the Annunciator or that may have developed in unmonitored sections of the system. During the upgrade to 10 MWs, Modification Record 74-10 documented the addition of seven (7) new monitoring points to the "yellow leg" of the safety system. Modification Record 75-16 documented the addition of two portable units ("White Rats") to the monitoring circuit. Addendum 1 to Modification Record 75-16 documented the permanent mounting of fourteen (14) individual monitoring circuits, which were contained in the portable units, to a sub panel located on the right side of the reactor control room Instrument Panel. Modification Record 75-16, Addendum 2 documented the relocation of the monitoring circuit from this subpanel to a subpanel on the left side of the Instrument Panel in support of installing the new Secondary Cooling System pump control circuit. Modification Record 75-16, Addendum 3 documented the revision to the "White Rat" Panel overlays due to the replacement of instrumentation for the replacement Primary Coolant System heat exchangers HX 503A and 503B. The attached draft of the "White Rat" Panel overlays shows the following revisions: For the "Green Leg" of the Safety System: Add Contact "K62-2" between terminal point P7-F and K26-2 to be worded as "FIRST." For the "Yellow Leg" of the Safety System: Add Contact "K61-2" between terminal point P6-L and K31-2 to be worded as "FIRST." This modification is being performed in support of the FIRST Preliminary Long-Form Modification Record. Why a Short Form is appropriate. (At least one of four reasons listed on Page 1, with justification) The short form of the Modification Record is appropriate because (a) this is an Addendum to an existing, previously reviewed and approved Modification Record, and (b) this is a modification to a non-safety system that requires documentation and review only. 2 Attachment 8.1

ATTACHMENT 20 ORIGINAL 2 AP-RO- 115 Revision 3 I 06-3; Addendum Modification Number: MODIFICATION DESCRIPTION Provide a concise description of the system change. Include any proposed PRE-OPERATIONAL TESTS required for this change. (If additional pages are necessary, insert after this page.) This Modification Record documents the replacement of the Center Test Hole Canister temporary wear ring with a different design. The new ring covers a larger circumference of the Flux Trap Holder; ensuring rotation will not disengage the position sensing switches. The Center Test Hole (Flux Trap) is that portion of the reactor through the center of the core bounded by the 4.5 inch inside diameter tube and extends 15 inches above and below the core vertical centerline. The Center Test Hole Canister is inserted into this region of peak thermal flux (6 x 10A14 n/cmA2-sec) for the purpose of material irradiations. The flux trap can provide a rather large reactivity effect and is thus subject to a high degree of administrative control to minimize the possibility of inserting or removing a sample with a high reactivity worth during reactor operation. Three center test hole assemblies are designed and approved for use at the MURR, the commonly used one being a three-tube, or "three-barrel' test hole canister. It consists of three hollow aluminum tubes, a guide foot to maintain alignment, a hold-down fixture to secure the sample contents in the three aluminum tubes, and a latching fixture to secure the holder to the island tube (inner pressure vessel). A wear ring is attached at the top of the test hole canister to mate with a similar ring attached to the island tube. The current temporary ring from Modification Record 06-3; Addendum 1 has two tabs attached with threaded fasteners that engage a pair of vertical plunger type switches. This wear ring will be replaced with a wear ring that has a solid extended ring that is fabricated as part of the wear ring. This ring is a 7 inch outside diameter ring that is 0.25 inches thick. This ring extends beyond the 4.487 inch outside diameter of the current wear ring. There are two machined gaps in the ring, orientated 180 degrees apart, to allow for proper alignment of the handling tool to disengage "latching fingers." These "latching fingers" are attached to the wear ring with threaded fasteners and latch onto the inner pressure vessel to secure the Canter Test Hole Canister when in place. A draft print showing the details of the wear ring modification is attached. This installation is being done in support of Preliminary Long Form Modification Record, "Flux-Trap Irradiations Reactivity Safety Trip (FIRST) Instrument Channel." The prototype FIRST support rig was installed under Modification Record 08-5, and subsequent details of the FIRST device and its function are provided in Modification Record 08-5. Why a Short Form is appropriate. (At least one of four reasons listed on Page 1, with justification) The short form of the Modification Record is appropriate because this is an addendum to a previously reviewed and approved Modification Record (Reason No. 1). 2 Attachment 8.1

ATTACHMENT 21 ORIGINAL AP-RO-l115 11-1 Revision 6 I Modification Number: MODIFICATION DESCRIPTION Provide a concise description of the system change. Include any proposed PRE-OPERATIONAL TESTS required for this change. (If additional pages are necessary, insert after this page.) Overview The Flux-Trap Irradiations Reactivity Safety Trip (FIRST) is a proposed addition to the Reactor Safety System that will ensure that the Center Test Hole Canister, commonly referred to as the Flux Trap Holder, and its contents remain in place during reactor operation. This feature will allow a change in the methodology that is currently used to calculate the reactivity contribution of samples loaded in the flux trap region.
Background
The current method of calculating the total reactivity worth of experiments in the Center Test Hole during reactor operation includes the reactivity contribution of the Flux Trap Holder. This is a conservative approach that severely limits the total available reactivity of samples loaded into the canister. Since the flux trap region has a positive void coefficient of reactivity, the empty canister itself appears as a void in the flux trap, thus adding a significant amount of positive reactivity (0.0036 delta-k for the 3-barrel holder and 0.0050 delta-k for the 6-barrel holder) to the calculation methodology. The MURR is considering an alternative methodology in which the reactivity contribution of the Flux Trap Holder is not included, and only the reactivity contribution of the experiment samples is included in the calculation. To conservatively implement this methodology, it is suggested that instrumentation be provided such that insertion or removal of the Flux Trap Holder cannot physically be performed during reactor operation. This instrumentation would provide an input signal to the Reactor Safety System such that the reactor could not operate unless the Flux Trap Holder, or strainer, is properly installed. Modification Record 08-5; "Install Temporary Prototype of the Flux-trap Irradiations Reactivity Safety Trip (FIRST) Device," documented the installation of a testing prototype for the FIRST. The prototype was installed in December 2008, and tested almost continuously since that time. The results of that testing are described primarily in the "Testing" section below, but are also referred to throughout this Modification Record. Several improvements as a result of the testing have been incorporated into the proposed FIRST device and described in the Preliminary Modification Record. The Preliminary Modification Record was reviewed in accordance with procedure, and produced several questions, which are formally answered in this Modification Record. Also included with those answers are answers to questions posed by the Nuclear Regulatory Commission (NRC) through the formal NRC amendment process. During the intervening time, several improvements as a result of both continued testing and the formal review processes have been incorporated into the proposed FIRST device and described in this Modification Record. (Modification Description continued on Page 2a) 2 Attachment 8.2
ATTACHMENT 21 ORIGINAL AP-RO-I 15 Revision 6 Modification Number: 1I-I MODIFICATION DESCRIPTION (con't) Theory of Operation The FIRST will comprise two new instrument channels using two independent sensors to detect the position of the Flux Trap Holder. When a sensor is 'made-up,' a relay coil is energized, maintaining a normally open contact in the closed position. This contact is one of several in series that make up one leg of the 24VDC input to the Safety System Non-Coincidence Logic Units (NCLU). This configuration is duplicated for the other sensor. When a sensor is no longer 'made-up,' the relay coil de-energizes, opening a contact, thus interrupting the 24 VDC input signal to the Safety System NCLU. The resulting trip of the NCLU will de-energize the Trip Actuator Amplifiers (TAAs) and scram the reactor. This action ensures that if the position of the Flux Trap Holder changes from its secured and latched position, reactor operation will cease. Conversely, if the sensors are not 'made-up,' the TAAs cannot be reset. This ensures that the Flux Trap Holder cannot be installed during reactor operation. Layout and Description The FIRST is two new instrument channels, including sensors, components and modules, which detect the position of the Flux Trap Holder and converts that position into a logic input to the Reactor Safety System. The FIRST is comprised of the following components: Flux Trap Holder Wear Ring, Sensor Switches, Support Rig, Relays and Power Supply, Safety System Interface, and FIRST Bypass Switches. Flux Trap Holder Wear Ring The wear ring is an existing component of the Flux Trap Holder. This wear ring is the top-most component of the Flux Trap Holder. Its position is fixed with respect to both the holder and the Island Tube (inner pressure vessel) when the holder is installed. The wear ring will be modified to provide a flanged radial extension at its top. This extension will be the reference point for contact with the sensor switches. Modification Record 06-3; Addendum I, "Install Temporary Flux Trap Holder Wear Ring," provides a basis for modifying the wear ring to perform this function. Modification Record 06-3; Addendum 2, "Replace Flux Trap Holder Wear Ring," documents modifications to the wear ring to perform the function described here. Sensor Switches The sensors chosen for this service are waterproofed plunger-type switches with molded cables of sufficient length to ensure all connections are made above the water line (see attached diagram of switch). These switches have been tested over several months and numerous cycles under their intended service conditions. Further testing description for these switches is provided in the later section, entitled "Testing." The material used in the fabrication of the instrument cable jacket is a form of neoprene called "Carolprene." As stated in the report Radiation Resistance of Elastomners, neoprene has good radiation resistant properties up to a fluence of I E8 rads and does not display signs of brittleness until approximately 3E8 rads. As measured directly at IOMWs, the radiation field on the pressure vessel head is approximately 1.3K rads/hr gamma and essentially no neutron. Assuming that the reactor operates on average 150 hours per week, 52 weeks/year at 10 MWs, it would take approximately 10 years to reach a fluence of 1E8 rads. (Modification Description continued on Page 2b) 2a Attachment 8.2
ATTACHMENT 21 ORIGINAL AP-RO-l 15 Revision 6 Modification Number: 11-1 MODIFICATION DESCRIPTION (con't) Full travel of the switch is 3/8-inch, is limited by the protective collars to be roughly 1/4-inch, and is expected to be compressed under service conditions to roughly 3/16-inch. Details of the FIRST device construction including the switches are provided in the attached draft MURR Print No. 2712. Support Rig The support rig will attach to the reactor pressure vessel head via the existing handling ears, and will support and vertically align the two independent switches that close when the Flux Trap Holder is in its secured and latched position. The support rig will be fabricated in-house from 6061-T6 Aluminum and 304 Stainless Steel as described in the attached draft MURR Print No. 2712. The support rig will be of welded construction, with the exception of the rack and pinion mechanisms, which must be accessible for inspection and repair. The support rig will have two extension legs protruding downward from the plate to ensure that the rig cannot tip over during handling evolutions at the pressure vessel head. The plate also features two additional '/2-13 UNC threaded holes for unanticipated handling evolutions. The support rig will use rack and pinion engagement pins to engage the existing handling ears of the pressure vessel head, will provide means to be positively installed, removed and stored, and will allow physical access to all bolts of the vessel head should the device prove unable to be disengaged and removed underwater. The rack and pinion engagement pins will be operated using a 2-inch rotating rod (a common handling tool in the pool), and will have opposed direction of operation to counter any induced moment. The switches will be adjustable in height, held in place using jam nuts, and be provided protective collars to prevent over travel of the switches. This condition would only occur in the event of improper handling or improper installation of the support rig. Cables from the switches will be attached beneath the support rig plate, and be provided adequate strain relief as they exit the support rig. Relays and Power Supply The relays will be of the standardized K-relay type, commonly used in the Safety System, which have an excellent service history. The relays, K-61 in the Yellow Leg and K-62 in the Green Leg, will be located in the existing K-relay drawer. This enables them to be accessible, use a standardized shorted relay if needed for testing and troubleshooting, and to provide a configuration consistent with existing Safety System components and operation. The relay coils will be powered via 24VDC Power Supply 2PS3. This power supply has ample capacity, is already present in the K-relay drawer, and currently powers all existing K-relays in the K-relay drawer. This approach will greatly simplify the installation of the new relays and again provide a configuration consistent with existing Safety System components and operation. (Modification Description continued on Page 2c) 2b Attachment 8.2
ATTACHMENT 21 ORIGINAL AP-RO-l 15 Revision 6 Modification Number: 11-1 MODIFICATION DESCRIPTION (con't) The normally open contact I from each relay will be connected into the existing Annunciator logic for the Power Level Interlock Scram. The contacts will be connected in series with the existing annunciator function to provide a scram annunciation in the event that any of the four contacts should open. The existing annunciator window "POWER LEVEL INTERLOCK SCRAM" will be replaced with a new annunciator window "PLI OR FIRST SCRAM." The normally open contact 2 from each relay will be connected into the existing Yellow and Green Legs as described below. Safety System Interface Two contacts will be added to the existing Yellow Leg and Green Leg series inputs to the Safety System. These normally open (meaning contacts will open when coil is de-energized) contacts (K-61, contact 2, in the Yellow Leg, and K-62, contact 2, in the Green Leg) will provide the ability to interrupt the 24VDC input signal to the Safety System. The resulting trip of the respective NCLU will de-energize the TAAs and scram the reactor. All contacts in the Yellow and Green Legs are shown in the Reactor Safety System Monitoring Circuit (commonly referred to as the "White Rat") Panel Overlays. Modification Record 75-16; Addendum 3, "Reactor Safety System Monitoring Circuit ("White Rat") Panel - Revision to Panel Overlays in Support of Modification Record 05-8," provides a previous basis for revising the overlays to this panel. Modification Record 75-16; Addendum 4, "Reactor Safety System Monitoring Circuit ("White Rat") Panel - Revision to Panel Overlays in Support of Flux-Trap Irradiations Reactivity Safety Trip (FIRST)," will document revisions to the overlays to this panel to indicate the function described here. FIRST Bypass Switches The FIRST Bypass Switches (IS29 in the Yellow Leg, and IS28 in the Green Leg) will provide the following two functions: (i) allow testing and troubleshooting capability, and (2) provide the use of both the proposed methodology and the current methodology for calculating the reactivity contribution of samples and the holder in the flux trap region. When it is desired to use the current methodology of including the reactivity contribution of the Flux Trap Holder, the First Bypass keys will be inserted and the switches placed in the "BYPASS" position. The bypass switches will be of the standardized keyed-type, currently used in the Safety System with an excellent service history, and labeled I S29 and 1 28. They will be located in the Reactor Console adjacent to the existing bypass switches. The switches directly jumper each FIRST sensor switch to energize relay coils on K-61 and K-62. This configuration provides the Reactor Operator a direct and unmistakable indication at the Reactor Console that this Safety System function is bypassed. Installation of the bypass switches requires relocating the Annunciator RESET and TEST pushbuttons. These pushbuttons will be relocated to directly above the existing Annunciator ACKNOWLEDGE pushbutton. (Modification Description continued on Page 2d) 2c Attachment 8.2
ATTACHMENT 21 ORIGINAL AP-RO-1 15 Revision 6 Modification Number: 1l-I MODIFICATION DESCRIPTION (con't) System Layout and Routing
- a. The support rig is held in place by the lifting ears of the Pressure Vessel Head.
- b. The switches are supported and aligned by the support rig.
- c. The Flux Trap Holder wear ring engages the sensor switches.
- d. Switch leads are routed through the Pool, through an access on the south side of the Bridge, and down to a junction box on the Mezzanine.
- e. Switch leads will continue on through existing chases to the keyed bypass switches, I S29 and I S28, on the Reactor Console.
- f. Switch leads will continue on through existing chases to the Instrument Panel area.
- g. The switch contacts control the coils of relays K-61 and K-62 in the K-relay drawer.
- h. The normally open contacts of these K-relays provide an additional series contact in each of the Yellow and Green Legs of the Reactor Safety System.
- i. An additional normally open contact in each relay provides an input to the "PLI OR FIRST SCRAM" Annunciation.
Redundancy Considerations The applicable questions addressable in IEEE-279 are outlined in the Hazards Summary Report Evaluation (page 3) of this Modification Record. These proposed instrument channels are most similar to existing instrument channels that provide a reactor scram in the event that any one of the three primary or pool coolant system isolation valves V507A, V507B, or V509 come off their open seat. Only failure modes that are conservative and operationally limiting can occur due to the installation of these instrument channels. Testing A temporary installation was put in place in December 2008. This device was instrumented with the sensor switches proposed here, but was connected to a digital chart recorder to monitor the operation and reliability of the switches and their support rig. Detailed assessments of the support rig and its switches have been performed on several occasions since initial installation. Choosing a suitable and reliable sensor switch was a major focus area for implementing these instrument channels. Extensive bench and in-situ testing was performed to ensure the chosen switch could perform well. Initial testing of the switch was done in a deionized (DI) water bath, where the switch was mechanically cycled many times to verify water-tight integrity. Next, repeatability testing was done to ensure the switch travel and contact break point could be consistently achieved. Excellent precision was obtained in this testing. As stated above, full travel of the switch is 3/8-inch, is limited by the protective collars to be roughly 1/4-inch, and is expected to be compressed under service conditions to roughly 3/16-inch. Testing revealed that the contact closed at roughly 1/8-inch of compression, and opened at roughly 5/64-inch of compression. Testing was extremely consistent for any one switch, and varied between switches by as much as 1/32-inch. These bench tests plus the in-pool support rig testing support the choice of these switches for their intended service. (Modification Description continued on Page 2e) 2d Attachment 8.2
ATTACHMENT 21 ORIGINAI. AP-RO- 115 Revision 6 Modification Number: 1I-! MODIFICATION DESCRIPTION (con't) The intended precedent for establishing switch height in the rig is to allow 3/16-inch travel between fully compressed at the protective collar and 'contact-open.' This will allow roughly 1/8-inch of vertical travel prior to initiating a FIRST scram if the Flux Trap Holder is moved from its secured and latched position. See the License Amendment Response section for a detailed discussion of the reactivity response due to moving the Flux Trap Holder. Supporting Documents This work will be performed in conjunction with a modification of the wear ring for the "3-barrel" Center Test Hole Canister. Modification Record 06-3; Addendum 2 will document the modification of this wear ring to provide engagement of the wear ring to the switches described here. This work will also be performed in conjunction with a modification to the Reactor Safety System Monitoring Circuit ("White Rat") Panel Overlays. Modification Record 75-16; Addendum 4 will document revisions to the overlays to this panel to indicate the function described here. 2e Attachment 8.2

ATTACHMENT 21 ARIGINAL AP-RO-! 15 Revision 3 I Modification Number: 11-1 REACTOR SAFETY EVALUATION Does this change involve a revision(s) to the Technical Specifications or a safety hazard as described in 10 CFR 50.59? NOTE: A licensee may make changes to the facility as described in the HSR without obtaining a license amendment only if: (i) A change to the Technical Specifications incorporated in the license is not required, and (ii) The change does not produce any of the following results: I. More than a minimal increase in the frequency of occurrence of an accident previously evaluated in the HSR;
- 2. More than a minimal increase in the likelihood of occurrence of a malfunction of an SSC important to safety previously evaluated in the HSR;
- 3. More than a minimal increase in the consequences of an accident previously evaluated inthe HSR;
- 4. More than a minimal increase in the consequences of a malfunction of an SSC important to safety previously evaluated in the H-ISR,
- 5. Create a possibility for an accident of a different type than previously evaluated in the HSR;
- 6. Create a possibility for a malfunction of an SSC important to safety with a different result than any previously evaluated in the HSR;
- 7. Altering or exceeding a design basis limit for a fission product barrier as described in the HSR;
- 8. A departure from a method of evaluation described in the HSR used in establishing the design bases or the safety analyses.
Yes: Y_ No: Signature: 45 $Ž Z Date: ___________ If YES, the change must be performed using a Long Form Modification Record. If NO, outline the basis for the decision. YES, this change does involve a revision to the Technical Specifications and is therefore being performed using a Long Form Modification Record. Additionally, in order to implement this change, the Technical Specification revision is being performed by application for License Amendment and must be approved by the U.S. Nuclear Regulatory Commission prior to implementation. Technical Specification 3.1.g states: "The reactivity worth of each secured removable experiment shall be limited to 0.006 delta-k." Technical Specification 3.1.h states: "The absolute value of the reactivity worth of all experiments in the center test hole shall not exceed 0.006 delta-k." In the past, MURR has conservatively included the reactivity worth of the sample canister within the definition of an "experiment" in the center test hole. The intended methodology is to count only the reactivity worth of the samples, and not the reactivity worth of the canister, toward the absolute value of the reactivity worth of the experiments in the center test hole. Technical Specification 3.3 will be revised to include two instruments, or measuring channels, in the reactor safety system that will sense the position of the center test hole canister. The capability to bypass the channel will also be included in the instances where MURR opts to include the reactivity worth of the canister. 4 Attachment 8.2

ATTACHMENT 21 ORIGINAL Responses to Crew Review and Evaluation Questions Crew response produced a total of twenty-four questions from six operators. Those questions and the formal response to them are provided below. The original NRC license amendment request was evaluated under the relicensing process. This initial evaluation produced a total of seven questions, to which MURR responded on August 31, 2010. The FIRST portion of the relicensing process was then evaluated as a separate NRC license amendment. This second evaluation produced a total of five questions, to which MURR responded on January 31, 2011. Following the above response, a third evaluation produced a total of four questions, to which MURR responded on July 11, 2011. Following the above response, the NRC requested clarification on the usage of the "center test hole Strainer." MURR responded on December 19, 2011. The four responses to NRC requests for additional information are provided in the following section. Formal Response to Crew Review Questions Question 1: On page 26, paragraph 4 it refers to isolation relay coils. It might be more clear if it's noted that this is the type of relay. When I hear isolation I think about an isolation ofcontainment. The term 'isolation', where it refers to the relays, has been removed from the Final Modification Record. Question 2: Secondly. the mod record refers, in several places, including the HSR changes (8.2 and Add. 4) to instrument channel in the singular. By tech spec definition, 1.7 this should be two instrument channels especially as we are including IEEE 2 79 discussion and taking creditfor redundancy. The FIRST system should correctly be referred to as two instrument channels. This correction has been made throughout the Final Modification Record. Question 3: Along this same line, does only having one bypass key negate that redundancy? After all the two channels join together where one failure could take out both trips. The same point should be consideredfor the routing of the wires. MURR has chosen to use two bypass keys. This change has been made throughout the Final Modification Record. Question 4: Finally in the rewrite of HSR add 4 A.3.3.15 the relays are referredto as 2K61 and 2K62. Unless I've missed something they should be K61 and K62. The correct reference to the relays should be K61 and K62. This error has been corrected in the Final Modification Record.
ATTACHMENT 21 ORIGINAL Question 5: Page #7. New CP is listed as CP-38, but the draft is number CP-36. The correct CP is CP-36. This error has been corrected in the Final Modification Record. Question 6: Could the PM to inspect the FIRST rig also include an inspection of the wire and mounts? This revision has been incorporated into the PM. A draft of this PM is included in the Final Modification Record. Question 7: How is the wire to be mounted? The routing of the cables is described in the Final Modification Record. Mounting of the cables is depicted in MURR Print 2712, Sheet I of 3. A draft of this Print is included in the Final Modification Record. Question 8: Print 2712 is referenced as having 3 sheets: however only I (page 3) is included A draft of MURR Print 2712, Sheets I of 3, 2 of 3, and 3 of 3 are included in the Final Modification Record. Question 9: Print 139 - The yellow leg monitoringpoint 6 should be before the Rx loop B low flow scram. This error has been corrected on Print 139. A draft of the corrected Print is included in the Final Modification Record. Question 10: Print 139 - Since 1S28 bypasses the FIRST scram, should this not also be included in the print. Bypass Switches I S29 and I S28 bypass the FIRST scrams by powering the coils to relays K61 and K62, which then maintain contacts closed that are depicted on Print 139. The bypass switches and the K-relay coils they energize are depicted on Print 138, Annunciator Control. Question 11: Page 3 Rev IA: should read "... use of thisfacility will be interlocked with the reactor safety system to ensure that the reactor will SCRAM should the center test hole canisterbe removed..." Agreed. This correction has been made in the Final Modification Record. Question 12: Page 3 Ic, Id." Mod record lists Figure8.4 and8.5 as being revised, but they are not included in the Mod record Recommend either including the prints or remove them from the Mod record. This revision is included in the flux trap wear ring mod record. Figure 8.4 and 8.5 were revised by Modification Record 06-3, Addendum 2. These Figures will be referenced in the Final Modification Record, but not revised. Question 13: Page 3a.IH: Since we are adding section 9.9 do we need to addressthe change in the following section numbers.
ATTACHMENT 21 JRIGINA - Section 9.9 is being added to the end of Chapter 9 of the Original HSR. Following Section numbers in the combined Original and Addendum volumes will not be revised. Question 14: CP-36 should include section 3.3 as a reference. Technical Specification 3.3 has been included as a reference in the draft of CP-36, which is included in the Final Modification Record. Question 15: CP-36 uses siandardphrasefor placing bypass key to 'OFF'. Steps 26 and 17 shoud read "PlaceFIRST scram bypass switch 1S28 to "OFF"position. This nomenclature has been standardized throughout the draft of CP-36, which is included in the Final Modification Record. Question 16: CP-36 should we test with 3 barrelflux trap device also? Each of the three holders featuring the flanged wear ring section have been test fit on the support rig and shown to make up the switches regardless of which device is installed. CP-36 will continue to use the strainer due to ease of installation and removal, but could be adequately performed using any of the three holders. Question 17: Figure 9.2 need to add labelsfor 1S28 and new location ofAnn. Test switch. This oversight has been corrected in the draft Figure 9.2, which is included in the Final Modification Record. Question 18: CP-36 why not complete this cp with pool andprimary systems on line? To remain consistent with current CP methodology, CP-36 will continue to utilize jumpers in place of systems on-line. However, a systems on-line alternative could be added to a future CP revision if distinct advantages to doing doing so emerge after implementation. Question 19. RX-Q2 step 6 remove the "orplaced in storage" this would also ensure the installationof the rig is checked The rig can be stored ajiercompletion of the PM While this wording was considered, it was determined that proper installation of the support rig should be determined prior to each use, and will be performed during Start-Up Checks. The OR portion of step 6 will remain to provide the LSRO with flexibility. Question 20: Do we need tofabricate additionalshortedrelays? No. All CPs can be performed without requiring additional shorted relays. CP-30 will use the most at seven of the eight available. Question 21: Probably need to consider slight revision to definition of '*Experiment" in TS during amendment request. Otherwise goingfrom 3-barrel to 6-barrel would be a change in "normal" reactor component change.
ATTACHMENT 21 OR(. INAL The purpose of the amendment and the FIRST system is to remove the holder from its role as a part of the experiment, and make it a "normal" part of the reactor. Regardless of which holder or strainer is installed, it will be considered and administratively controlled as a "normal" part of the reactor. Question 22: Add a step in startup checks to verify bypass status? The totalflux trap holder and loading can have different limits depending on whether FIRST is bypassedor not. During startup checks, the configuration of the FIRST will be administratively determined by the Reactor Manager or his designee, and this will be reflected by signature on the Flux Trap Loading Sheet. If bypass keys are authorized and in place, this condition will be annotated on the startup checksheet as approved by the Reactor Manager. Question 23: There are penned corrections on the print. Further revisions including penned corrections to all prints have been incorporated into the draft prints, which are included in the Final Modification Record. Question 24: Also there is a post added to the rigs that have been built that is not reflected on the prints. Print 2712 has been extensively revised to depict several additional features, including the stabilizing posts. A draft of this print is included in the Final Modification Record.
ATTACHMENT 21 ORIGINAL August 31, 2010 Response to NRC regarding seven questions CHAPTER 10 10.5 Section 10.3. 1, Center Test Hole. Related to license amendment request of August 6, 2009.
- a. Describe any occurrences where the center test hole canisterfailed to properly latch or when a canisterwas removedfrom the reactor when not intended.
Each time the center test hole canister is installed, proper latching is verified by two members of the Operations staff, one being a licensed senior reactor operator, both visually and physically (by pulling upward on the canister rope). Instances in which the center test hole canister can not be verified latched result in reinstallation or repair followed by verification. The hold-down fixture within the canister is also verified latched prior to installation. With the hold-down fixture and the existing latching means being verified at each installation, no instances of improper latching or unintended canister removal have occurred.
- b. Describe any changes to proceduresfor sample handling or irradiationin the center test hole necessitated by the installation of the flux-trap irradiations reactivity safety trip (FIRIX) system.
The existing procedures for sample handling in the center test hole will remain essentially unchanged, with the following exception: with the ability to operate the FIRST system in BYPASS, the appropriate administrative reactivity limit must be selected by the loading preparer, and reviewed and approved by the Assistant Reactor Manager-Physics. If the FIRST system is in BYPASS, the reactivity worth of the center test hole sample holder must be included in the calculation of the absolute value of the reactivity worth of all experiments in the center test hole. BYPASS operation will require Reactor Manager's approval to perform.
ATTACHMENT 21
- c. Describethe possiblefailure modes of the switches used on the FIRST system.
In December, 2008, a temporary, prototype FIRST device and a mock instrument channel were installed to test operation and reliability of the FIRST system, including the switches. This test has continued to date in order to accumulate operating experience in using the device and to validate its long term reliability. Within the first few months of the test, it was determined that the original center test hole canister wear ring design could potentially prevent proper contact with the switch plungers, thus preventing the switches from closing and 'making-up' the safety system input. The wear ring was redesigned to ensure full contact with the switch plungers and no additional problems regarding proper contact have occurred. The failure mode mentioned above - where a switch failed to close - is conservative in that the safety system cannot be reset. While the failure mode where a switch cannot open the contact has not occurred, the failure of one switch would not prevent the remaining switch from performing its intended safety function. The mode where contact make or break could change with respect to plunger travel or maladjustment have not been observed but would result in one of the above two failures - not closing or not opening. However, neither is a reactor safety system failure. Periodic surveillance and maintenance inspections will also reveal maladjustments in switch positioning or potential switch failures that do not make themselves apparent through nuisance trips.
ATTACHMENT 21
- d. The SAR states that the cablejacket will displaygood radiationresistancefor about 10 years of operation. Discuss the consequences of any potentialfailure of the FIRST cabling.
Degradation of the FIRST cabling is specifically noted during periodic inspections, and cabling is replaced if signs of degradation are present. Failure modes for the cabling will result in either open circuit, a conservative failure where the safety system cannot be reset, or closed circuit, where the condition would not prevent the remaining circuit from performing its safety function. Periodic surveillance and maintenance inspections are intended to bring to light any cabling degradation prior to failure, and failure modes can be shown to be conservative.
- e. Discuss the proposed methodology that will be used to determine sample reactivity when the FIRSTsystem is in use.
The current methodology that is used to determine the reactivity present in the flux trap region or center test hole involves several independent measurements as described below. The same methodology will be used to determine sample reactivity values when the FIRST system is in use. The reactivity neutral condition of the reactor, as far as the central flux trap region is concerned, assumes a center test hole filled with just water (at 110 °F) and no individual experimental samples or the center test hole canister (also known as the removable experiment sample canister as defined in TS 1.3) installed. The reactivity contribution of the center test hole canister is first determined by performing two back-to-back reactor startups; first one with the center test hole empty (only water present) and the second one with an empty center test hole canister - either the 3 or 6-barrel as described in Section 10.3.1.2. The difference in the control rod heights between the two startups in conjunction with the known integral rod worth curve is then used to determine the reactivity contribution from the empty test hole canister. Any reactivity contribution due to the temperature change is accounted for by the primary and pool coolant temperature coefficients of reactivity and the corresponding temperature difference between the two critical measurements.
ATTACHMENT 21 The same methodology is used to determine the total reactivity contribution from a fully loaded sample holder. That is, two back-to-back reactor startups are performed; one with just water in the central region and the second one with the loaded test hole canister. The difference in control rod heights is used to determine the reactivity contribution from the loaded center test hole canister. Individual sample materials are irradiated in the central test hole by placing them inside tightly sealed standard sized aluminum cans. Materials that require multiple encapsulations are first placed inside smaller sealed quartz or aluminum vials and then placed within the welded aluminum cans. Typically, several of these individual sample cans are placed inside the tubes that make up the center test hole canister. The reactivity contribution from these individual sample targets are also measured in a very similar fashion. After estimating the possible reactivity worth of a new individual sample target to determine no reactivity limits will be exceeded, two back-to-back reactor startups are performed. First, a hollow thin-walled aluminum can filled with water (referred to as water can) with the same dimensions as the individual sample can is placed within one of the center test hole canister tubes and a reactor startup is performed. Next the water can is replaced with the sample can of unknown reactivity and a second reactor startup is performed. The difference in the control rod heights is then used to determine the reactivity worth of the unknown sample. The current methodology that is used to determine the total reactivity present in the flux trap region, including the reactivity contribution of the center test hole canister itself, will be the same methodology used when the FIRST system is in BYPASS. The proposed methodology that will be used when the FIRST system is in use does not include the reactivity worth of the test hole canister, but continues to sum the reactivity worth of the individual samples. The sum of the individual sample reactivity worth is and will be subject to existing Technical Specification limits, as well as more restrictive administrative limits, and must be approved by the Assistant Reactor Manager and Lead Senior Reactor Operator prior to loading. The methodology is also described in a letter to the NRC, dated August 6, 2009, requesting to amend the Technical Specifications that would allow implementation of the FIRST system.
ATTACHMENT 21
- f. Provide a discussion of how the design of the FIRST system meets the requirements of IEEE-279.
The single failure criterion of IEEE-279 is completely met at the component level. The channel independence criterion of IEEE-279 will in large part be met, but in the case of certain components will not be fully complied with. Detection of the canister position must occur in the same physical space and from the same physical surface. This is a commonly accepted practice, where the channel independence criterion does not have to be extended to mean independent detection devices. Certain channel components, such as in-pool cabling and the BYPASS switch, are not physically separate. Where these proximities are concerned, no credible failure can be expected to occur that would simultaneously prevent both channels from performing their safety functions. Thus the design of the FIRST system effectively meets the intent of IEEE-279.
- g. There does not appear to be a surveillance requirement to help ensure proper operation of the FIRST system. Propose and justify an appropriate surveillance requirementfor the FIRST system or explain why a surveillance is not needed As required by Technical Specification 4.4.a, the FIRST system will be tested for operability on a semiannual basis. A draft surveillance procedure (compliance procedure CP-36, "FIRST Scrams") has been prepared to verify proper operation of the FIRST system with regard to the reactor safety system.
A draft preventative maintenance procedure (RX-Q2, "Inspect FIRST Support Rig") has been prepared to ensure mechanical integrity of the FIRST system, and will be performed quarterly.

- 5. Location Requested:
A dedicated laboratory in the eastward expansion of the MURR Industrial Building (MIB) has been constructed for this project. The Reactor Manager, Reactor Health Physics Manager and the Reactor Safety Subcommittee will review the 10 CFR 50.59 Screen prepared for this laboratory to help ensure all Reactor License and Technical Specification requirements are met.
- 6. Purpose and General Description of Project:
ATTACHMENT 24 The following is a brief description of the process:
- a. The irradiated tellurium dioxide targets will be delivered to the MURR Target and Waste Handling Hot Cell (HHC) where the targets will have their encapsulation removed. The target material will be placed in crucibles and transferred to the Processing Hot Cell (PHC) via a pass through between the cells.
- c. The bulk product solution will be sealed in a suitable transfer vial and transferred via a pass-through to the HHC for transfer via shielded cask to the Dispensing Hot Cell (DHC) for formulation into final product solution. It will then be dispensed according to customer requirements into vials suitable for shipping. An aliquot will be taken from the bulk solution and removed from the DHC for QC analysis.
After cooling down the furnace and removing the expended target material, a second process may be performed. The expended target material (waste) will be sealed in a can within the PHC. After multiple processes and when the can is full it will be allowed to decay for a sufficient time and then will be moved via the pass-through to the HHC for interim storage.
- 7. Special Facilities/Utilities/Equipment Required:
A hot cell train, specifically designed for containment of 1-131 during the production process, has been constructed. This system of cells and the processing equipment were purchased as a turnkey system from a manufacturer with extensive experience with 1-131 production. Details for these hot cells and their design are included in a 10 CFR 50.59 Screen that will be reviewed by the Reactor Manager and Health Physics Manager. The design incorporates multiple barriers to help ensure any potential release of 1-131 will be controlled to well within 10 CFR 20 limits for both normal operation and potential accident conditions. Any potential 1-131 release, during normal operation, will be controlled to be within the goals of the MURR ALARA Program. A description of the 1-131 Laboratory and equipment follows. A. 1-131 Processing Laboratory Location The 1-131 Processing Laboratory will be located within a new two level building addition attached to the MURR Industrial Building (MIB), (Figure 1). The design of the attached building will incorporate the necessary floor loading for the 1-131 hot cells and the height requirements for the necessary ventilation exhaust system filter banks. Two consultants, one with previous and one with current 1-131 production experience, have provided input to the laboratory and process design.
ATTACHMENT 24 Figure 1- MURR Industrial Building Expansion B. Design Considerations for the 1-131 Hot Cells The processing laboratory will contain three adjoined and inter-connected hot cells located on the ground level (see Figure 2, next page): a target and waste handling hot cell (HHC); a processing hot cell (PHC); and a dispensing hot cell (DHC). The HHC and the PHC will have 200 mm (7.9 inches) of vertical lead shielding and the DHC will have 100 mm (3.9 inches) of vertical lead shielding. The area to the rear of the cells, labeled the cask loading area, is where the cell support facilities and equipment are located and where all cell inputs and outputs occur. The area in front of the hot cells, labeled the operator area, is where the cell windows, manipulators and controls will be located. The design philosophy for the hot cells is to provide adequate personnel shielding and containment of the ]-131, precluding or minimizing any potential release to the individual cells to the reactor facility or to any unrestricted area. The three (3) cell hot cell processing system incorporates a six (6) detector radiation monitoring system (ALMO-6) designed to provide radiation dose level information to the process operators. Three of the detectors are located at the operator's work station where the hot cell manipulators are located. These detectors provide real time dose rate information to the operators when they are performing a process. The remaining three detectors are located next to the first in a series of charcoal filters located above each of the three bays of the processing hot cell. These are designed to give the process operators real time information related to the capture and loading of I-131 onto the first charcoal filter in each bank of the individual cells. This allows the process operators to monitor the condition of the charcoal filters and will alert them of the need to change to an available bank of alternate filters.

ATTACHMENT 24 B1. Target and Waste Handling Hot Cell Design Features The target and waste handling hot cell (HHC) is designed for two principal purposes: (1) to receive irradiated targets and house support equipment to remove the target encapsulation and (2) to store process waste for an interim period. This cell will have a floor access to allow entry of irradiated targets from a target transfer cask designed to seal with the cell floor port. Here the target encapsulation will be removed and the irradiated TeO 2 material will be placed in crucibles and transferred via a pass-through to the PHC. The HHC containment is provided by appropriate negative pressure and an exhaust system that includes high efficiency particulate filters (HEPA) and high efficiency gas absorber filters (HEGA). The cell will be designed to have waste materials from the PHC returned via a pass-through chamber for interim storage. The pass-through will have a door at each side and will be sized to hold any object that will be moved to and from the PHC. The waste material from the PHC (e.g., expended target material, contaminated used equipment) will be placed in containers with press-seal lids. The volume of the waste cell will be designed to hold the process waste for approximately 10 half-lives of the 1-131 (about 80 days) after which time the cans may be moved to longer term shielded storage. The cell will have 200 mm (7.9 inches) thick vertical lead shielding with a stainless steel liner and will have two master-slave-manipulators (MSM) penetrating the cell from the operator side. B2. Processing Hot Cell Design Features The processing hot cell (PHC) is where the dry distillation of the TeO 2 targets will be performed. This cell will have 200 mm (7.9 inches) thick vertical lead shielding with a stainless steel liner and two master-slave manipulators (MSM) which will penetrate the cell from the operator side of the cells. There will be a shielded entry door on the rear of the cell which will be used primarily for the initial setup of process equipment. After process equipment setup and cold testing it will be sealed and any subsequent equipment and consumables will enter the cell through the pass-through from the HHC. The PHC will have a pass-through chamber for moving waste material to the HHC. The sodium iodide (I-131) product solution will be moved to the DHC in a sealed vial via transfer back to the HHC and then with a cask to the DHC. The PHC, during processing, will provide three barriers to prevent the release of radioactive material to the environment: (1) the processing equipment itself, (2) an additional inner containment for the separation furnace within the PHC with a dedicated iodine filter, and (3) the PHC containment provided by appropriate negative pressure and an exhaust system that includes high efficiency particulate filters (HEPA) and high efficiency gas absorber filters (HEGA). The process is designed to contain 1-131 within the process equipment; therefore, there should be minimal release of airborne radioactivity to the hot cell. The hot cell will be connected to the facility exhaust ventilation system so that any releases from the hot cells will be through the ventilation system on the 1-131 processing laboratory (including a dedicated stack gas monitor), as well as the facility exhaust ventilation system where it is again monitored by the facility off-gas radiation monitoring system. B3. Dispensing Hot Cell Design Features The dispensing hot cell (DHC) will be des: to receive the bulk 1-131 in .rneciallv desi~med transnort cask_ This cell will have a sealable floor port for entry of items such as product vials, lead pigs, and dispensing equipment. This port will also be the exit point for the shielded pigs containing 1-131 product.
ATTACHMENT 24 The dispensing cell will have 100 mm (3.9 inches) of vertical lead shielding and will have two MSM penetrating the cell from the operations side. Its containment will again be provided by appropriate negative pressure and an exhaust system that includes high efficiency particulate filters (HEPA) and high efficiency gas absorber filters (HEGA). C. Design Considerations for the 1-131 Process C1. Target Fabrication The targets will be fabricated in a laboratory space that includes a dedicated ventilated enclosure to assure the quality of the targets. Hazards identification in the Sigma-Aldrich Material Safety Data Sheet (MSDS) indicates that TeO 2 has no known OSHA hazards. The same MSDS indicates TeO 2 is not a dangerous substance according to the Global Harmonization System of Classification and Labeling of Chemicals (GHS).' The target mass will be adjusted to the fluence predicted at the target irradiation location to produce a peak 1-131 activity limited to by the RUR. The techniques for developing the targets for mass production while maintaining the necessary QC of the targets are being developed. C2. Target Processing MURR plans to remove the two layers of target encapsulation within the HHC using a MURR designed can opener. The irradiated TeO 2 material will then be placed in crucibles and transferred to the PHC via the pass-through. Below is an example of the processing equipment for the dry distillation of tellurium dioxide for 1-131 production. This process is similar to dry distillation processes described in IAEA-TECDOC- 1340,
ATTACHMENT 24 C3. Target Waste Disposal The crucibles, containing expended target material after each process, will be placed in a disposal container to reduce the spread of contamination inside the cell. When full, the disposal container will be sealed and transferred to the HHC for temporary storage. Health Physics staff has performed an analysis of the waste stream. This analysis is documented in the "Safety and Design Review for the Proposed Production of 1-131 at the MU Research Reactor," and will only be summarized here. The analysis indicates that expended target material would require a minimum of 52 weeks decay before being considered for disposal. The analysis recommends that adequate storage be provided to allow a minimum of 1.5 to 2 years decay in order to decrease the handling dose that would be incurred during preparation for shipment and to decrease the cost of disposal.

Written documents related to handling of radioactive materials Procedures approved by the Project Leader or Co-Project Leader and Health Physics Manager, or draft procedures with a Radiation Work Permit (RWP) are required for all target processing and activities involving greater than 100 mCi. Checklists associated with these procedures will be completed for each performance of these procedures to provide documentation of activities, dose rate measurements, dosimeter readings, and other information relevant to the process. Completed procedure checklists will be filed with Document Control in the project file for reactor license project RL-76. The following activities will be controlled by procedure and will incorporate the Standard Operating Procedures where applicable as required by the Reactor Manager and Reactor Health Physics Manager.

HP may require additional protective clothing during special evolutions. Gloves will be worn: When handling radioactive samples or performing work in the laboratory. Safety Glasses: Will be worn when performing or observing work in the laboratory. Monitoring requirements: Whole body and ring dosimeters will be worn by all personnel. Continuous air monitoring will be set up at predetermined locations to provide early detection of potential loss of hot cell containment. HP personnel will be required for all transfers into and out of the hot cells. Special monitoring requirements: MURR will establish an 1-131 thyroid monitoring program which will require all persons who will enter the laboratory to have a baseline thyroid measurement followed by periodic checks thereafter at a frequency determined by HP. The entire processing procedure will initially be covered under an RWP by HP personnel. Early warm run and scale-up activities may identify additional monitoring requirements for each step in the process or activity based on dose rates measured during a portion of the process or at a container surface for sam leP2en ssed out of the shielded hot cells. Analytical samples of the final product solution will be removed from the DHC for quality purposes. Product solution dispensed for transportation will be removed from the DHC in lead pigs. An HP is required to be present whenever material is introduced or removed from the 1-131 hot cells.
ATTACHMENT 24 Processing personnel must check out on frisker or portal monitor when leaving the 1-131 Laboratory. Lead shielding of product vial containers will be swipe-checked for contamination before being transferred to the transportation packaging area. Transfer casks used for target delivery will be swipe-checked before leaving the 1-131 Laboratory. Any work area suspected of potential contamination will be swipe checked in a timely manner.
- 9. Administrative Controls and Training Requirements:
Quality Control of the target material is extremely important to prevent the introduction of unwanted contaminants into the target material. This is important to help ensure the quality of the final product as well as providing consistency in correlation of dose rates measured during the warm runs and scale-ups. Personnel training and approval requirements will be unique to this project and will be reviewed and approved by appropriate supervisors and health physics. The hot cell and equipment suppliers will provide specific training for operation of the hot cells and operation of the process equipment within the hot cells as part of a turn-key contract for the production of 1-131. Class I training is required for authorized supervisors. Additionally, authorized supervisors must have comprehensive project related knowledge and experience sufficient for them to supervise and/or train workers to perform project specific procedures. Class II training is required for approved workers under this project. Additional task-specific training by an authorized supervisor is conducted in accordance with an approved SOP.
- 10. Anticipated Radiation Doses and Contamination Levels:
The HHC and PHC will have 200 mm of lead shielding. Calculations show that if a target were placed against the 200 mm wall of the cell the resulting dose rate outside the cell would be less than 20 mR/hr. The 1-131 process equipment will not be adjacent to the wall so contact reading outside the cell will be less and the processing person will have an additional distance which will make the dose rate lower at the receptor position. Monitoring of early wann runs will provide actual dose rate to compare to the estimates. Other results for Dose Levels: Microshield Results for Hot Cell Shielding Assumed 100 Ci of 1-131 and 6 Ci of Te-131m (24 hour decay) HHC and PHC - 200 mm Pb DHC - 100 mm Pb 1-131 Te-131im Total 1-131 only Dose (mR/hr) with (negligible) 0.09 mR/hr 0.09 mR/hr 0.16 mR/hr source in middle of hot cell Dose (mR/hr) with (negligible) 1.1 mR/hr 1.1 mR/hr 7.9 mR/hr source at inner wall surface
ATTACHMENT 24 The 1-131 target transfer cask is designed to handle up to four, 180 gram TeO 2 targets. These will be transferred to the hot cells no sooner than 24 hours post EOI, at which time the significant contributions to dose are from 1-131, Te- 131 in and Na-24. Using a conservatively high activity content for these isotopes of of 1-131, 20 Ci of Te-131m and 0.15 Ci of Na-24, calculations indicate that the contact dose rate on the transfer cask surface will be
- and the dose rate at 1 foot will be ý. Monitoring of early warm runs will be used to confirm these calculations.
Overall, it is anticipated that dose to workers will be similar to doses received by workers on other isotope production projects currently performed at MURR.
- 11. Transfer, Waste Production, and Disposal Requirements:
Waste Volume: Liquid waste is expected to be minimal for this dry distillation process. Liquid waste will be from water or dilute NaOH used for cleaning the cell after processing. This liquid will be absorbed and contribute to the estimated solid waste stream. Dry active waste is expected to be less than 0.5 ft3 per process and comprised of expended target material and paper product used for cleaning. The dry waste will be stored in sealed "paint" cans within the processing cell until full and then transferred to the HHC for interim storage.
Description:
Solid: expended target material, plastic syringes, QC samples, waste aluminum cans and lids Long-Lived: Long-lived isotopes will be decayed for sufficient time and then sent off site for disposal. It is anticipated that a minimum decay of 52 weeks for any target material is required to meet disposal criteria. It appears it will be most cost effective to store the waste for 1.5 to 2 years. Initially the plan is for waste to be stored in sealed cans within the waste handling hot cell and then transferred to shielded interim storage, after sufficient decay, prior to preparation for shipment. Liquid samples for assay: Liquid analytical samples will be transferred to an appropriate laboratory for analysis.

ATTACHMENT 25 Attachment to 10 CFR 50.59 Screen No. 12-07, "Iodine-131 Processing Laboratory" (In support of RL -76, "Production of 1-131 Radiochemical Sodium Iodide Solution") 1.0 Introduction The University of Missouri Research Reactor (MURR) has evaluated the safety considerations necessary to safely irradiate and process tellurium dioxide (TeO 2 ) targets to produce radiochemical sodium iodide (1-131) solution. Preliminary investigation into the feasibility of such an endeavor resulted in the document, "Safety and Design Review for the Proposed Production of 1-131 at the MU Research Reactor." This document, which includes a preliminary assessment of safety, regulations and process, recognized that a significant investment in infrastructure and equipment was necessary to pursue the goal of producing 1-131 safely and reliably. Using information provided by two consultants with 1-131 experience and literature research of other facilities producing 1-131 safely, this 50.59 Screen evaluates the infrastructure and equipment that MURR has incorporated into the design of the 1-131 Processing Laboratory. 2.0 1-131 Processing Laboratory Location The 1-131 Processing Laboratory will be located within a new two-level building addition attached to the MURR Industrial Building (MIB) (see Figure 1). The design of the attached building will incorporate the necessary floor loading for the 1-131 hot cells and the height requirements for the necessary ventilation exhaust system ducting and filter banks. Two consultants, one with previous and one with current 1-131 production experience, have provided input to the laboratory and process design. Figure 1 - MURR Industrial Building Expansion
ATTACHMENT 25 3.0 Design Considerations for the 1-131 Hot Cells The processing laboratory will contain three adjoined and inter-connected hot cells located on the grade level (see Figure 2): a target and waste handling hot cell (HHC or HC-1 1A); a processing hot cell (PHC or HC- I1B); and a dispensing hot cell (DHC or HC- I1C). The HHC and the PHC have 200 mm (7.9 inches) of vertical lead shielding and the DHC has 100 mm (3.9 inches) of vertical lead shielding. Table 1 provides the lead thicknesses of all of the hot cell components in millimeters. The area to the rear of the cells, labeled the cask loading area, is where the cell support facilities and equipment are located and where all cell inputs and outputs occur. The area in front of the hot cells, labeled the operator area, is where the cell windows, manipulators and controls are located. Table 1 - Hot Cell Lead Shielding (in millimeters) The design philosophy for the hot cells is to provide adequate personnel shielding and containment of the 1-131, precluding or minimizing any potential release to the individual cells, or to the reactor facility, or to any unrestricted area.
ATTACHMENT 25 Figure 2 131 Processing Laboratory
ATTACHMENT 25 3.1 Target and Waste Handling Hot Cell Design Features The target and waste handling hot cell (HHC or HC-I 1A) is designed for two principal purposes: (1) to receive irradiated targets and house support equipment to remove the target encapsulation, and (2) to store process waste for an interim period. This cell has a floor access to allow entry of irradiated targets from a target transfer cask designed to seal with the cell floor port. Here the target encapsulation is removed and the irradiated TeO 2 material is placed in crucibles and transferred via a pass-through to the PHC. The cell is designed to have waste materials from the PHC returned via a pass-through chamber for interim storage. The pass-through has a door at each side and is sized to hold any object that will be moved to and from the PHC. The waste material from the PHC (e.g., expended target material, contaminated used equipment) will be placed in containers with press-seal lids. The volume of the cell is designed to hold the process waste for approximately 10 half-lives of the 1-131 (about 80 days) after which time the cans may be moved to longer term shielded storage. The cell has 200 mm (7.9 inches) thick vertical lead shielding with a stainless steel liner and two master-slave-manipulators (MSM) penetrating the cell from the operator side. This cell will also have a sealable glove box for entry of items such as product vials and processing equipment. 3.2 Processing Hot Cell Design Features The processing hot cell (PHC or HC-1 1B) is where the dry distillation of the TeO 2 targets is performed. This cell has 200 mm (7.9 inches) thick vertical lead shielding with a stainless steel liner and two master-slave manipulators (MSM) which penetrate the cell from the operator side of the cells. There is a shielded entry door on the rear of the cell which will be used primarily for the initial setup of process equipment. After process equipment setup and cold testing it will be sealed and any subsequent equipment and consumables will enter the cell through the pass-through from the HHC. The sodium iodide (1-131) product solution will be moved back to the HHC in a sealed vial through a pass-through. Note: A pass-through has been designed between the PHC and DHC that could be used in the future to transfer the product solution from the PHC directly to the DHC. The PHC, during processing, provides three barriers to prevent the release of radioactive material to the environment: (1) the processing equipment itself, (2) an additional inner containment for the separation furnace within the PHC with a dedicated iodine filter, and (3) the PHC containment provided by appropriate negative pressure and an exhaust system that includes high efficiency particulate filters (HEPA) and high efficiency gas absorber filters (HEGA). The process is designed to contain 1-131 within the process equipment; therefore, there should be minimal release of airborne radioactivity to the hot cell. The hot cell will be connected to the facility exhaust ventilation system so that any releases from the hot cells will be through the facility exhaust ventilation system and monitored by the facility off-gas radiation monitoring system. An additional off-gas radiation monitor will also be installed in the MIB Expansion.
ATTACHMENT 25 3.3. Dispensing Hot Cell Design Features The dispensing hot cell (DHC or HC-1 IC) will be designed to receive the bulk 1-131 in solution from the HHC in a specially designed transport cask. The bulk sodium iodide-131 radiochemical will then be dispensed in bulk quantities to meet customer order requirements. This cell will also have a sealable glove box for entry of items such as product vials, lead pigs, and dispensing equipment. The dispensing cell has 100 mm (3.9 inches) thick of vertical lead shielding and two MSM penetrating the cell from the operator side. 4.0 Design Considerations for the 1- 131 Process 4.1 Target Fabrication The targets will be fabricated in a laboratory space that includes a ventilated glove box to assure the quality of the targets. Hazards identification in the Sigma-Aldrich Material Safety Data Sheet (MSDS) indicates that TeO 2 has no known OSHA hazards. The same MSDS indicates TeO 2 is not a dangerous substance according to the Global Harmonization System of Classification and Labeling of Chemicals (GHS).' The techniques for developing the targets for mass production while maintaining the necessary QC of the targets are being developed. 4.2 Target Processing MURR plans to remove the two layers of target encapsulation within the HHC using a MURR designed can opener. The irradiated TeO2 material will then be placed in crucibles and transferred to the PHC via the pass-through. Below is an example of the planned process equipment for the dry distillation of tellurium oxide for 1-131 production. This process is similar to dry distillation processes described in IAEA-TECDOC-1340, "Manual for Reactor Produced Radioisotopes," page 99.
ATTACHMENT 25 Figure 3 131 Processing Equipment 4.3 Target Waste Disposal The crucibles, containing expended target material after each process, will be placed in a disposal container to reduce the spread of contamination inside the cell. When full, the disposal container will be sealed and transferred to the HHC for temporary storage. Reactor Health Physics staff has performed an analysis of the waste stream. This analysis is documented in the "Safety and Design Review for the Proposed Production of 1-131 at the MU Research Reactor," and will only be summarized here. The analysis indicates that expended target material would require a minimum of 52 weeks decay before being considered for disposal. The analysis recommends that
ATTACHMENT 25 adequate storage be provided to allow a minimum of 1.5 to 2 years decay in order to decrease the handling dose that would be incurred during preparation for shipment and to decrease the cost of disposal. 5.0 Design Considerations for the 1-131 Laboratory and Hot Cell Exhaust Ventilation System 5.1 Introduction The heating, ventilation, and air-conditioning system (HVAC), which supports the MIB Expansion, provides heated and conditioned air for the spaces within that facility, creating an acceptable working atmosphere for personnel and equipment. The ventilation system is also designed to perfornn the following radiological control functions:
- Maintain rooms 299T (hot cell operator area), 299U (hot cell cask handling area), and 299V (QC Laboratory) at a slightly negative pressure with respect to the surrounding areas to prevent the spread of radioactive contamination;
" Maintain hot cells HC- I1A (HHC), HC-1 lB (PHC), and HC- I1C (DHC) at a negative pressure to prevent the spread of radioactive contamination; " Provide the necessary air exchanges to ensure that radioactive airborne concentrations are maintained at levels which are below the limits of 10 CFR 20, Appendix B, Table 1 for restricted areas; " Provide the necessary filtration [charcoal and high efficiency particulate air (HEPA)] to ensure any radioactive airborne releases discharged to the environment are kept at minimum concentrations; and " Provide continuous monitoring of all radioactive airborne releases discharged through the MIB Expansion ventilation exhaust system.
The MIB Expansion HVAC system consists of an HVAC unit, Fan Filter Units (FFUs), charcoal and HEPA filter banks, an airborne radiation monitoring system, constant volume control valves (CVCVs), chill water coils, a preheat coil, hot cell exhaust ventilation fans, flow and pressure measurement devices, and associated ducting and dampers (See Figure 4). Air exiting the MIB Expansion through the exhaust ventilation system is continuously monitored for airborne activity by a radiation monitoring system. The monitoring equipment consists of a single-channel radiation detection system designed to measure airborne concentrations of radioactive iodine in the exhaust air that is sampled by a shrouded probe located in the ventilation ducting downstream of all of the hot cell and room filtration systems. The HVAC system in the MIB Expansion is divided into the following six (6) distinct zones or spaces: (1) corridors C299U and C299T, (2) hot cell operator area 299T, (3) hot cell cask handling area 299U, (4)
ATTACHMENT 25 QC Laboratory 299V, (5) hot cells HC-11A, HC-IlB and HC-I 1C, and (6) basement 199. Each zone or space is explained in detail below. 5.2 Corridors C299U and C299T Conditioned air is provided to these spaces by the MIB Expansion HVAC unit. Fresh air is supplied to the building expansion through a louver located on the north face of the building. Fresh air is mixed with return air and conditioned by the HVAC unit and then ducted into corridors C299U and C299T. 5.3 Hot Cell Operator Area 299T The ventilation system for room 299T consists of four (4) FFUs and two (2) chill water coils. Make-up air is supplied to the room through louvers located on the north and south ends of the room FFU header at a rate of approximately 250 cubic feet per minute (cfm). The air is then exhausted through a CVCV, HEPA filter and a (selected) parallel charcoal filter (one filter on service - one in standby) into the facility main ventilation exhaust system at a rate of approximately 250 cfm. Air is removed from the room by the exhaust system at a rate of approximately 3 to 5 air changes per hour (ACPH). The make-up and exhaust air flows are adjusted to maintain the room at a slightly negative pressure (approximately 0.05 inches of H20 or greater) in relationship to the surrounding area. The four (4) FFU's recirculate the air within the room at a rate of approximately 30 to 60 ACPH through the two (2) chill water coils. 5.4 Hot Cell Cask Handling Area 299U The ventilation system for room 299U is very similar to that of 299T but consists of only three (3) FFUs, two (2) chill water coils and one (1) electric preheat coil. Make-up air is supplied to the room through a louver located on the north end of the room FFU header at a rate of approximately 160 cfm. The air is then exhausted through a CVCV and the same HEPA and parallel charcoal filter system which also supports room 299T and then into the facility main ventilation exhaust system at a rate of approximately 100 cfln. The air is also exhausted as make-up air for the hot cells at a rate of approximately 60 cfin. Air is removed from the room by the exhaust system at a rate of approximately 3 to 5 ACPH. The make-up air and exhaust flows are adjusted to maintain the room at a slightly negative pressure (approximately 0.05 inches of H20 or greater) in relationship to the surrounding area. The three (3) FFUs recirculate the air within the room at a rate of approximately 30 to 60 ACPH through the two (2) chill water coils and 1 preheat coil. 5.5 QC Laboratory 299V Air is supplied to room 299V from the HVAC supply ducting at a rate of approximately 450 cfm. The air is exhausted from the room through a fume hood, a CVCV, HEPA filter and a (selected) parallel charcoal filter (one filter on service - one in standby), and then into the facility main ventilation exhaust system at a rate of approximately 450 cfm. The supply and exhaust flows are adjusted to maintain the room at a slightly negative pressure (approximately 0.05 inches of H2 0 or greater) in relationship to the surrounding area. The air is recirculated within the room by two (2) FFUs at a rate of approximately 30 to 60 ACPH.
ATTACHMENT 25 5.6 Hot Cells HC-I IA, HC-11B, and HC-11C The supply and exhaust ventilation for hot cells HC-1 1A, HC-I lB and HC-I I C, which are the handling, processing and dispensing hot cells, respectively, consists of an intricate combination of HEPA and charcoal filtration systems, two (2) booster fans, and flow measurement and control devices. The supply and exhaust systems for each cell combine to form a common header, but each hot cell has its own independent filtration system. Air is supplied to each hot cell from a common header (suction located in room 299T) through a HEPA and charcoal filter at a rate of approximately 17 cfm. Air is exhausted from each hot cell through an intemal parallel set of charcoal filters, then through a (selected) external parallel charcoal and HEPA filtration bank (one bank on service - one in standby), a CVCV, a second (selected) parallel charcoal filter (one filter on service - one in standby), and then through a (selected) parallel exhaust fan into the facility main ventilation exhaust system at a rate of approximately 60 cfin (one fan operating - one in standby). Air is removed from the hot cells by the exhaust system at a rate of approximately 10 ACPH. The exhaust fans are 3 HP centrifugal models, each controlled by an Adjustable Speed Drive (ASD) that maintains a constant flow rate of 60 cfm through the system based on a control signal from a pressure transmitter located between the CVCV and the second set of charcoal filters. The transmitter measures a static pressure of approximately 2 to 8 inches of H20. The fans are powered from lighting panel LP-46. There are two glove boxes mounted to the hot cells; one on the north end of HC- I1A and one on the south end of HC-I IC. These gloves boxes provide the means of introducing or removing items from the hot cells. Each glove box also has its own independent supply and exhaust system. Air is supplied to each glove box at a rate of approximately 1.7 cfm through a combination HEPA/charcoal filter. Air is exhausted from each glove box through a charcoal filter and then a HEPA filter. The exhaust ducting for each glove box connects to the hot cell common exhaust header downstream of the hot cell filtration systems. 5.7 Basement 199 Air is supplied to the basement from the MIB Expansion HVAC supply ducting at a rate of approximately 450 cfm. Air is circulated through the area and back up to the grade level through a louver located in the stairwell.

ATTACHMENT 25 6.0 Evaluation of an 1-131 release in the Processing Hot cell The PHC will have the highest possible content of volatile 1-131. This is a very conservative assumption for two reasons: (1) and (2) the furnace is designed with a containment which has a dedicated charcoal filter such that minimal 1-131 can escape the furnace containment to enter the hot cell volume. Any indication of leakage from the process equipment into the hot cell (e.g., malfunction of the process equipment) would cause staff to secure the furnace resulting in the 1-131 evolution to be reduced and then to cease. 6.1 High Level Evaluation Initial assumptions regarding 1-131 release: Technical Specification (TS) 3.7, "Facility Gaseous and Particulate Radioactivity Release," specifies that the maximum stack discharge rate shall not exceed MPC (now Air Effluent Concentration - or AEC) for a maximum controlled instantaneous release concentration (averaged over 24 hours) for halogens with half-lives greater than 8 days (1-131 half-life is 8.05 days). The AEC for 1-131 in 10 CFR 20, Appendix B, Table 2, column 1 is 2E-10 pCi/ml. This is equivalent to the radionuclide concentration that, if inhaled or ingested continuously over the course of a year, would produce a Total Effective Dose Equivalent (TEDE) of 50 mrem. The MURR exhaust ventilation system, operating at 30,500 cfm, has a flow rate equivalent to 1.24E12 ml/day (4.5E14 ml/yr). If one assumes a release at the TS 3.7 limit concentration averaged over one day, this would equate to: (2E- 10 pCi/ml) x (1.24E 12 ml/day) = 248 pCi/day To meet TS 3.7 any 1-131 release from the stack, averaged over 24 hours, would need to be less than 248 pCi total. For this analysis, the design goal for the hot cell ventilation exhaust system is to limit the 1-131 activity to less than this value before the radioactivity enters the facility main ventilation exhaust system. This design goal assumption considers the dilution by the exhaust flow rate but does not take credit for any additional reduction of 1-131 activity (by plate-out or other means) in the facility main ventilation exhaust system.
ATTACHMENT 25 6.2 Conservative Evaluation of Charcoal Filters (intended to bound the assumptions in 2.2.6.2 of the Accident Analysis provided by GSG/ITD) GSG hot cell design provides two charcoal filters in series in the exhaust system for each cell; one internal and one external (see attached drawing). Each of these charcoal filters has a stated design efficiency of 99.97% (as derived from the absorption effectiveness of 3E-4 reported in GSG email, 12/9/2013). This implies a decontamination factor (DF) of 3333/charcoal filter. For this evaluation the DF will be conservatively assumed to be 1000/charcoal filter (which is a reduction in efficiency to 99.9%). [This is the efficiency used for the charcoal filters for the GA experiments]. This evaluation focuses on the PHC as the highest potential source of 1-131 gas. RUR 440, "Tellurium Dioxide," limits the maximum target inventory to
- such that the accident scenario during target irradiation is bounded by the Maximum Hypothetical Accident (MHA). It appears that yield calculations based on target density may actually result in an inventory of less than = per target. For this analysis a more conservative 200 Ci/batch will be assumed to be in the PHC furnace at one time.
[GSG document "Safety Aspects and Troubleshooting" recommends a transmission factor (TF) of I E-3 for the emission of 1-131 from the 1-131 iodide solution." Another document published in the Journal of Nuclear Medical Technology, "Volatility of radiopharmacy-prepared sodium iodide-131 capsules," indicates a release in an experiment of 0.035% of the activity in 24 hours which appears to be consistent with the TF recommended by GSG/ITD.]ii If the entire = inventory was released into the PHC the two vendor-supplied charcoal filters in series (one inside and one outside) would provide a DF of 11E6, such that the downstream inventory of 1-131 would be a maximum ý entering the part of the ventilation exhaust outside the 1-131 laboratory. This would be sufficient to meet the instantaneous (24-hour) release limit of 248 PtCi/day. GSG has recommended that MURR add at least one charcoal filter beyond their supplied charcoal filters as a precautionary measure (mainly to protect the main facility ventilation system from residual contamination). Two different scenarios are shown in the following drawing. The first assumes a release in the PHC filtered by 3 filter banks (two supplied by GSG and one additional filter bank supplied by MURR) all operating at decontamination factors of 1000. The resulting release into the MURR stack would be M. The second scenario assumes degradation of the filters to a DF of 100, resulting in
- E release into the stack.
ATTACHMENT 25 With DF of 100 (99-0%efficiency) the instantaneous release limit shou ld not be exceeded The evaluation above intentionally neglects the added barrier provided by the GSG design where the furnace is in a containment/confinement with a charcoal filter that could reduce any 1-131 activity within the furnace by at least a factor of about 1000 before the activity entered the hot cell volume. Ignoring this additional stage of charcoal filtration provides additional conservatism to the release scenario. The evaluation also neglects the fact that the 1-131 evolved from the furnace occurs over a short period of time (about 1 hour) and is continuously being captured in the = traps. Procedures will dictate that, if any unexpected 1-131 release were to occur into the cell during a distillation process, the furnace would be secured and 1-131 evolution would be reduced and then cease. Perhaps a more realistic source term could be considered based on the time release of 1-131. During the distillation process in the furnace the evolution of the target 1-131 inventory occurs roughly 6.3 Other Considerations Because containment (confinement) of 1-131 requires the hot cells to be kept at negative internal pressure at all times, redundant hot cell exhaust fans will be installed. GSG/ITD has provided a procedure by which the hot cells can be placed in a condition for exhaust fan maintenance activities but this procedure requires extensive time consuming clean-up of the cells prior to securing the facility exhaust fans.
ATTACHMENT 25 6.4 Analysis of a Stack Release of 1-131 from a Spill of 1-131 Sodium Iodide Solution Outside of the Hot Cell (this evaluation is consistent with analysis 2.2.7 of the Accident Analysis provided by GSG/ITD) The scenario involves a spill of 50 Ci of 1-131 Sodium Iodide solution during packaging of product outside the DHC. This 50 Ci is based upon the assumption that a nominal = shipment to a customer (U3) would be distributed among I vials. 13 has specified a concentration of ý, so 50 Ci would occupy 7.7 ml in the 20 ml vial. During the accident, perhaps a broken vial, the solution flows onto the floor of the laboratory. The value of possible airborne activity stack release is calculated using an estimated transmission factor (TF) equal to L.OE-3 for the 1-131 release from solution. This evaluation considers a charcoal filter with DF of 1000 (supplied by MURR) on the ventilation exhaust from the room. Release to stack = (50E6 1 iCi) x TF x DF (MURR laboratory filter) Release to stack = (50E6 jtCi) x (1E-3) x (1E-3) = 50 tiCi This calculated value is less than the 1-131 24-hour release activity limit. A rough calculation of the airborne activity possible in the 1-131 laboratory indicates about a four (4) minute stay time in the potential concentration before annual limits would be reached (see analysis below). Obviously, from an ALARA perspective, any clean-up effort would require persons to use respiratory protection equipment. The DAC for 1-131 is 2E-8 pCi/ml. The estimated volume of the laboratory cask loading area is 2900 ft3, or _ 8.2E7 ml. Applying the TF of 1.0E-3 to the 50 curie spill would result in a release of 5E4 gCi from the solution into the lab volume. This results in an 1-131 concentration of 6.1 E-4 pCi/ml in the laboratory volume, or: (6.1E-4 pCi/ml / 2E-8 pCi/ml / DAC) = 30,500 DAC Since 2000 DAC-hours results in a dose of 50 Rem CDE to the thyroid, the stay time to reach this limit is given by: 2000 DAC-hours / 30,500 DAC = 0.066 hours or 3.96 minutes or - 4 minute stay time. This scenario is very unlikely because the DHC will have interlocks that will only allow product vials to be removed from the hot cell while in a cask insert.
ATTACHMENT 25 6.5 General Information Regarding Charcoal Adsorption Filtersiv
- a. Elemental iodine is absorbed by attraction of the iodine to the carbon. This is referred to as Kinetic adsorption. Kinetic adsorption of a gas molecule or chemical vapor is the physical attraction of the molecule to the carbon granule by electrostatic forces. These forces, as they apply to small particles, are termed van der Waals forces.
- b. The capacity of activated carbon is the percentage of its own weight that an activated carbon can absorb of a given vapor under certain conditions (vapor concentration, temperature, humidity, air velocity). One gram of carbon will absorb one milligram of iodine.
- c. Elemental iodine, once absorbed, usually stays absorbed.
- d. The lower the concentration of a material, the harder to achieve a high removal percentage.
- e. With a properly designed HEGA system that includes proper absorber selection, absorbent and resident time, any absorbable contaminant can be filtered and contained. The grade of carbon designated Grade A is activated 8 x 16 mesh carbon and is used to absorb elemental iodine.
- f. Carbon filters must exhibit a minimum mechanical efficiency of 99.9%, use high quality coconut shell activated carbon, and be sized for about 0.125 second residence time.
- g. All filters should be installed in "bag-in/bag-out" housings to protect maintenance personnel.
- h. Decontamination factor (DF) is the ratio of the concentration (or activity) of a contaminant in the untreated (unfiltered) air to the concentration (or activity) of the contaminant in the treated air. It is the reciprocal of the penetration expressed as a fraction. It is calculated from a known efficiency as: DF = 1 / (1- efficiency). Efficiency is calculated from a known DF as: efficiency
= 1-(1/DF).
- i. Residence time is the term given to the time that a gas stream contacts a carbon bed. The concept of residence time is very important for the designer because the removal efficiency of an absorber is determined by the type and amount of contaminant in the gas stream, the type and amount of absorbent, and the residence time.
