VPRAŠANJE
Dear Customer,

We would appreciate your responses on the following questions:

Question 1:
Section 5.3 provides detailed information about the drums (210 and 120 liters) to be used for conditioning secondary waste. In the section it is said that second-hand contaminated drums have being used in other occasions. Additionally, it is described the conditioning method and characteristics of the cement, sand, concrete mixer and the recipe. Should be understood that drums will be provided by NEK?. Should be understood that the conditioning process should be performed on site (Krsko) with existing mixer and materials from NEK?

Question 2:
Is section 7 some general radiological data is provided. It is also said that specific activity concentration of each isotope (per drum) will be provided to the Bider. However this detailed information can not be found in the tender documentation. This data is critical to verify waste acceptance criteria of our incinerator. Is it possible to have the announced information for each 53 drums?

Question 3:
Section 7.4 refers to 100 liter drums instead of the 120 liter drums requested in previous sections. Please confirm the requested size of the inner drum that shall content the secondary waste.

Question 4:
Section 8.1 request the bidder to be authorized for incineration activities. Would it be acceptable to involve the incinerator as a subcontractor, in such a way that the license holder will be the incineration company and not the bidder itself?

Question 5:
As per section 9.1 incineration shall be done in 2021. Considering deadlines of the biding process, necessary administrative steps to perform legal agreements for waste acceptance between counties, international transportation and other administrative constraints, it is not realistic to execute the incineration in 2021, unless a predefined bidder had this paper-work ready in advance. Is it possible to extent the date for accomplish the incineration?

Question 6:
The responses on the questions above have influence on our technical and commercial proposal. Therefore, we would appreciate if the deadline for presenting the proposal can be extended for two additional weeks.

Best regards.
