physics coverage will be provided by a full-time Radiation '

Safety Service (RSS) health physicist and all personnel exposures will be maintained ALARA.

i Please note that the U-M is requesting an expeditious reply to this SNM-179 amendment request - due to an immediate need. by the Ford Nuclear Reactor (FNR) staff to initiate this work. Please note

, that the FNR is increasingly being utilized as the irradiation site for neutron irradiation damage studies in support of programs such as the U.S. Nuclear Regulatory Commission Heavy Section Steel Irradiation (HSSI) Program.

! Adequate neutron dose monitoring of test specimens being irradiated will require greater use of Np-237 and depleted uranium dosimeters.

The U-M is requesting an increase in the maximum possession amount for Np-237 from the current 20 milligrams to 5 grams with respect to Line I and adding Line X (doploted uranium) because of increased need for these type of dosimeters. Note that the U-M is requesting a modification to the encapsulation requirements for the NP-237 (Line I) to better accommodate the needs for various experimental designs.

Thank you for your time, effort, and immediate attention to this SNM-179 amendment request. Your expeditious approval will be greatly appreciated by the staffs at the Ford Nuclear Reactor and

) Department of Energy. Please do not hesitate to contact the PNR Assistant Manager, Philip Simpson, at the PMh/FNR Facility ((313) 764-6220) or me at Radiation Safety Service ((313) 764-4420)-should you have any questions, comments, or concerns regarding this amendment request or correspondence, t

j

Dear Mr. Null:

j The following are estimated activities for the various Np-237 encapsulation materials i requested in item 7(1). The estimates are based on a 100 hour0.00116 days <br />0.0278 hours <br />1.653439e-4 weeks <br />3.805e-5 months <br /> irradiation followed by 30 1

days decay in the reactor pool prior to handling for shipment.

1-Aluminum encapsulation: No significant long lived activity The primary activation products are Al-28 ( Tu2 = 2.24 m ), Mg-27 ( T ie= 9.45 m ), and Na-24

( T ic= 15.02 h ).

l

{. Titanium encapsulation: 1.0 pCi Sc-46 (Ti c= 83.8 d ) ar..! 0.15 pCi Ca-45 (Tu2= 163 d).

Other activation products are relatively short lived; Ti-51 (Tl/2= 5.76 m ), Sc-47

(T ic= 3.41 d ), Se-48 (Tic = 43.7 h ), Sc-49 (Tv2=57.3 m ), and Sc- 50 j (Tv2= 1.71 m ).

i-i Vanadium encapsulation: No significant long lived activity. The primary activation products are V-52 (Tu2= 3.76 m ), Ti-51 (Tu2= 5.76 m ), Sc-48 (Tu2= 43.7 h ),

l and Sc-47 (TU2=3.41d).

L Stainless Steel encapsulation: 10 mci Cr-51 (T ta= 27.7 d),1.1 mci Fe-55 (Ti n= 2.73 y),

! 1 mci Co-58 (Tu2=70.9d),300 pCi Co-60 (Tv2=5.27 y). 200 itCi Mn-54

{ (T ic= 312 d),200 pCi Fe-59 (T ic= 44.5 d),80 pCi P-33.(T e= i 25.3 d), and .

i 20 pCi Ni-63 (T ic= 100 y).-

L As is readily apparent, the stainless steel encapsulation presents a significantly greater radiological hazard than the other encapsulation materials. We conservatively estimate the

, exposure rate from the stainless steel at one meter in air to be less than 20 mR/hr. It is our 5

intent to use aluminum, vanadium or titanium in preference to stainless steel encapsulation -

- whenever possible, f All radioactive materials are handled ALARA at the University. IThe Phoenix Memorial

, - Laboratory / Ford Nuclear Reactor (PMUFNR) has a full time independent Health Physics

- staff assigned by Radiation Safety Service who approve and monitor all transfers of the radioactive materials from the facility which will include the materials in this amendment -

request. All reactor facility personnel handling the materials will be full time staff members .

Appropriate safety equipment such as lab coats, gloves, bootics, safety glasses, long reach handling tools, shieldmg, and minimization of handling time will be used as l needed to minimize personnel exposure, in addition, the PML/FNR has a fonnal daily contamination smear survey program to detect and eliminate radioactive contamination.

The survey program includes all areas where the materials requested in this amendment will be handled.

Following irradiation, the depleted uranium will be stored in the FNR pool or the PML radioactive material storage cage (Rm 10690) until they are shipped to the DOE or other . licensed facilities for counting, analyses, and disposal. Individual dosimeter foils or wires of depleted uranium will be limited to a mass of 50 milligrars.

Please note that the U-M is requesting an expeditious reply to this SNM-179 amt.ndment request due to an immediate need by the Ford Nuclear Reactor (FNR) staff to initiate this work. Please note that the FNR is increasingly being utilized as the irradiation site for neutron irradiation damage studios in support of programs such as the U.S. Nuclear Regulatory Commission Heavy Section Steel Irradiation (HSSI) Program.

Adequate neutron dose monitoring of test specimenu being irradiated will require greater use of Np-237 and depleted uranium dosimeters.

The U-M is requesting an increase in the maximum possession amount for Np-237 from the current 20 milligrams to 5 grams with respect to Line I and adding Linu X (depletsd uranium) because of increased need for these type of dosimeters. Note that the U-M is requesting a modification to the encapsulation requirements for the Np-237 (Line I) to better accommodate the needs for various experimental designs.

Thank you for your time, effort, and immediate attention to this SNM-179 amendment request. Your expeditious approval will be greatly appreciated by the staffs at the Ford Nuclear Reactor and Department of Energy. Please do not hesitate to contact the FNR Assistant Manager, Philip Simpson, at the PML/FNR Facility ((313) 764-6220) or me at Radiation Safety Service ((313) 764-4420] should you have any questions, comments, or concerns regarding this amendment request or correspondence.
