460.16 Provide justification for taking exception to Regulatory Guide l
1.143 by designing the chemical drain tank and the chemical treatment tanks to Standard PS 15-69.

RESPONSE
Table 1 of Regulatory Guide 1.143 provides equipment code 1
requirements for radioactive waste components. Note 2 to the table states that fiberglass-reinforced plastic tanks may be used in accordance with appropriate articles of Section 10 of the ASME Boiler and Pressure Vessel Code for applications at ambient temperature. The chemical drain tank and chemical drain treatment j
tanks are provided for collection of decontamination and chemistry j
laboratory chemical wastes. The chemistry composition of the collected fluids includes acids, chloroform, sodium hypochlorite, j
sodium hydroxide, sulfates, acetone, alcohols, and carbon tetrachloride. The aggressive corrosive effects of these substances warrants the use of fiberglass-reinforced plastic tanks and is the reason for this material selection.
2 The chemical drain tank and ' chemical drain treatment tanks are not under the jurisdiction of Section 10 of the ASME Boiler and Pressure Vessel Code because the normal operating pressure is atmospheric and does not exceed 15 psig (see Article C-121 of'ASME 4
Section 10). However, the tanks are designed, fabricated and tested in accordance with Product Standard PS 15-69, developed cooperatively with the industry and published by the National Bureau of Standards under the Voluntary Product Standard Procedures of the_U.S. Department of Commerce. (This standard was effective until withdrawn on January 20, 1982.)
It includes I
requirements for material, mechanical properties, minimum wall l
thicknesses and testing. The methods used for testing of barcol i
hardness, flexural strength and flexural modulus conform to ASTM l
D2583-67 and D790-66 which are the required methods listed in 1
article M-120 of ASME Section 10.
Additionally, PS 15-69 requires conditioning for testing in accordance with ASTM D618-61, testing for glass content based on ASTM D2584-67T, and testing for tensile strength based on ASTM D638-68. The tank manufacturer performs tests on samples for compressive strength as recommended by the
}
standard in accordance with ASTM D695-63T. The tank flanges and fittings are designed in accordance with ANSI B16.5 and ANSI B16.ll.
l Based on the above discussion, these tanks are considered to be j
appropriately designed, fabricated and tested for their application.
