Region I HWLee CEWilliams CRChappell RH0degaarden NMSS r/f U.S. Department of Energy SGTB r/f ATTN: Mr. Charles J. Mauck Dp-4 Washington, DC 20545 Gentlemen:
This refers to your application dated August 29, 1987, requesting renewal of Certificate of Compliance No. 6678 and an amendment for the Model No. LP-50. .
In connection with our review, we need the information identified in the enclosure to this letter.
To accommodate the various packaging configurations on the same certificate of compliance a consolidated application should be submitted which includes the pertinent information from the applications dated April 1978 and August 1987.
The application should provide drawings and a discussion and analysis of those features common to all configurations. The application should address the specific features of each configuration providing drawings and appropriate supporting information. The application should be in the format of Regulatory Guide 7.9.
Please advise us within 30 days from the date of this letter when the informa.
tion requested will be provided. If you have any questions regarding this matter, we would be pleased to meet you and your staff.
Your application dated August 29, 1987, requesting renewal of the certificate is considered to satisfy the condition for timely renewal. Accordingly, Certificate of Compliance No. 6678, Rev. 4, will not expire until a final determination has been made by the Commission.
Sincerely, Original Signed by CH A"TJ" 7 mwee 8801040430 871230 PDR ADOCK 07106678 PDR Charles E. MacDonald, Chief C _

- 1. The application should explicitly identify each different package configuration and show that each configuration meets the requirements of 10 CFR Part 71.
- 2. The packaging drawings have been reduced to the extent that the aimensions and notes are not legible. Provide a legible set of packaging drawings, showing each different package configuration separately.
- 3. The material properties used in Section 1.0 Structural Evaluation do not correctly reflect the change in materials (casting vs. plate and pipe) andthechangeinconstruction(castingvs.weldment).
- 4. Figure UG-34(b-2), cited in Item 2, page 1-3, is not applicable to the welded construction shown on the packaging drawings. A value for "C" which reflects the construction details should be selected. This condition also exists with the various factors used in the flange calculations. It is also noted that the flange calculations did not consider the conditions of Appendix II, Part 8, of the ASME Boiler and Pressure Vessel Code Section VIII, Division I, 1974 Edition. Part B addresses flange designs having metal to metal contact outside the bolt circle.
- 5. The calculations are not consistent in that the maximum allowable stress value cited by the ASME Code is not the design criteria used in all cases (Bottom Head, page 1-6).
- 6. It is not clear that the material thicknesses used in some calculations are the minimum thickness as required. Material thicknesses which are pertinent to the analysis should be shown on the packaging drawings.
