There are a number of corrections that should be noted. Nevertheless, the scientific content discussed in the paper is not affected by these corrections.
Page 1: Revised author list. A number of authors who contributed to the paper were missing in the author list. Antonio Vergara has been added as the article editor. Finally, one authorʼs name was also misspelled in the author list and is corrected. The list of missing authors and the corrected authorʼs name are detailed in the relevant sections of this article.
Page 4: Modification of texts. The second sentence in the first paragraph of section 3 Timeline should be modified. The modified text is written in italic font below.
Kfacilities throughout Europe. The facility description presented in this paper reflects the design status and schedule as of 2015-2016. ESS is in construction and an important first milestone will be the generation of the first neutrons by the target, in 2019. The accelerator will K Page 6: Revised author list for the Accelerator Design. There is a misspelled name in the author list. Specifically, I Levinsen should be corrected to Y Levinsen.

The reference [HABAINY15] should be added.
The unpolished specimens showed a fatigue limit of 150 MPa, whereas the polished one showed 237.5 MPa at 25°C [HABAINY15].
Page 70: Missing reference in section 2.2-Second sentence in the third paragraph. The reference [GORYNIN92] should be added.
For the test carried out at temperatures up to 500°C, the irradiated tungsten specimens fail in a brittle regime even at low radiation damage of 0.1 dpa [GORYNIN92]. Indeed, the ferritic/martensitic steels irradiated at LANSCE with the irradiation temperature below 164°C showed prompt necking at less than 2% plastic strain at the dpa value of as low as 0.5 [FARRELL01,MALOY01].   The tensile samples taken from the beam entrance region of the target vessel at SNS have been tested after the service lifetime of the first and second target [MCCLINTOCK14]. Page 80: Correction of wording in section 3.3.3 The 'collimator' in the first paragraph should be corrected to 'moderator'.
Page 80: Redundant reference in section 3.3.3. The [137,141] in the first paragraph should be corrected to [137], removing [137,141]. Figure 83 shows the fluid dynamic behaviour of the cold collimator system, over five beam pulses [137].

Page 81: Insertion of a new sentence in section 3.4. With an insertion of a new sentence, the first paragraph of section 3.4 should begin as follows.
3.4 Manufacturing moderator vessels Extensive investigations were performed early in the project at Forchungszentrum Jülich, department ZEA, as preparation for the manufacturing of the ESS cold and thermal moderator vessels. Machining, welding and quality assurance tests have been performed on the AL6061-T6 alloy that is used for the volume cold moderators. Nine vessels ...

Page 82: Missing reference in section 3.5.1-Third sentence in the first paragraph. The reference [WEEKS88,KAPUSTA03] should be added.
Its total elongation is more than 4% at a thermal neutron dose of 10 23 neutrons cm −2 that corresponds to about 1.5% of silicon yield in aluminium [WEEKS88,KAPUSTA03]. Operating experience at the high flux isotope reactor at ORNL shows that AL6061-T6 is able to withstand up to 40 dpa of irradiation, indicating that the pre-moderator is replaced every 7000 h [LU08].

Studies of the chemical reactivity of irradiated beryllium and steam indicate that hydrogen generation is enhanced at a temperature of 700°C, in a test in which the specimen experienced a temperature excursion above 1000°C [ANDERL98].

The development of the ESS Integrated Control System relies on contributions from institutes and competences centred within Europe in order to benefit from the existing experience and knowledge base. The in-kind partners involved in the ICS subproject are listed in table C2.
