This information is required by Title 10 of the Code of Federal Regulations (10 CFR) Section 32.210 and described in the relevant guidance document NUREG-1556, Volume 3, Revision 2, titled Applications for Sealed Source and Device Evaluation and Registration.
Description/Construction
- 1. Please confirm that there have been no changes made to BWM, BWM-T, BWM2, or BWM4 devices or source holder to accommodate the Kr85.T3 sealed source, this includes how the sealed source is secured/installed into the device source holders.
Radiation Profiles
- 2. In the amendment request, it states that the activity tolerance for model Kr85.T3 is
+/-26.5%, providing a maximum activity of 506 mCi. In addition, the amendment request also identifies that the KR85.1 sealed source may potentially have an activity tolerance of +35%, providing a maximum activity of 540 mCi. The registration certificate NR-0596-D-113-G states a maximum activity for KR85.1 of 400 mCi.
Since the BWM, BWM2, and BWM4 may contain up to a potential maximum of 540 mCi, please provide radiation profiles which reflect the potential maximum activity contained in devices.
- 3. As noted above, due to the load tolerance, we note that the BWM-T is authorized to contain up to two sources Kr-85 please provide updated radiation profiles which reflect the potential maximum activity contained in the devices of 1080 mCi.
- 4. Please provide the date when the change to the Kr85.T3 model will be made.
- 5. Please confirm that the dose requirements for generally licensed user are not affected based on the potential maximum activity of 1080 mCi.
